May I ask a non-nook Question?

I want to set up my PC as a TV and DVR, what's the best way to do this? I have a cable outlet right beside the PC, I know I could get a TV Tuner card but I know nothing about them at all and there are so many it's confusing. Hauppage(sp?) seems to be the most popular but are they any good? Are there any questions I should be asking myself before I chose? Any help would be much appreciated. Is there a better option altogether? I've searched the internet but it's basically an information overload, no good guides can be found for all the 5 year old junk

tuner you get depends on what software (dvr software) you want to run, what you want to do, and how fast your computer is.
things to know:
some with one tuner and some with 2
some with only OTA and some with QAM (unencrypted cable), some do both
hauppauge has pci/pci-e cards as well as usb
HDhomerun has several models, 2 tuner OTA/QAM, 4* tuner cable card, etc
Ceton has a 4, and a 6?, tuner card
some of these have hardware encoders, some dont (slower computers will need encoding otherwise it will be choppy, audio dropouts)

You should first figure out exactly what type of signal is coming in on that cable. Does your area still have analog cable service (my area does, but I think that's getting more scarce), or is it digital only? Are there any clear-QAM channels (which are usually just the local networks) or is it all encrypted? If it's only digital and encrypted channels that you're interested in, then you need something that can take a CableCARD.
After that, it's all about what software you want to run and how many tuners you require.

You may be better off just using a combo of Netflix, Hulu, Amazon Prime Instant Video and Bittorrent.
Otherwise you haven't given us any of your specs to be able you help you out. What type of PC do you have? Windows/Linux/Mac... Processor/RAM/HD, also like others have noted are you going for Over the Air signal, analog or Digital Cable, standard def or HD. Are you going to be using a set top box or going for a cable card(very expensive option). Give us as much detail as possible if you want competent answers.

As for using your PC as a TV and PVR, I'd recommend using XBMC to turn it into a Home Theater PC (HTPC). The site, LifeHacker, does an XBMC/HTPC guide every few months. You would still need to buy hardware like a TV tuner but XBMC does a lot on the software end.
Also, if you use XBMC, you can use your Nook Color (assuming you at least have rooted it and have access to the Andoid Market) to control the XBMC software via the XBMC remote app.
Here is a guide that lifehacker did. It's a little old but the basics are still relevant and correct. http*://lifehacker.*com/5536963/the-ultimate-start-to-finish-guide-to-your-xbmc-media-center (remove the asterisks)

What everyone else has said -- need more info on what you have, also what budget, and what cable setup.
I have an HTPC set up but it's for media streaming, not dvr recording.
One forum I found very helpful is the AVS forum (search in google), they have a sub-forum dedicated entirely to HTPCs.

Sorry for the lack on info didn't know that my PC specs mattered all that much. I am running:
Vista Home Premium, 64bit
Intel Core2 Quad CPU (Q9300 @2.5ghz)
4GB RAM
Nvidia GeForce GT240
Appx. 600gb ofhard-drive space plus a 500gb permanent external USB. I can add more HD space if it becomes a problem.
Not sure if there is any other system info you guys need.
As for my cable I dunno for sure what signal I have, I have COMCAST if that helps anyone. Mainly I want this for recording sports. I can't always watch them live and it'd be nice to DVR them for later. I'd also use it for shows, but those I can always watch online later. Can't really watch sports later though. And I'd also like to be able to just normally watch TV on my computer. I'd like to be able to do something on monitor one while the other plays live TV. Sports or whatever.
Also, to this:
Are you going to be using a set top box or going for a cable card(very expensive option).

I am not sure what you mean. I was thinking you get the TV Tuner, install it in your PCIE slot, and watch TV on the PC. Do you need another device?

A basic TV tuner will only be able to pick up Over The Air signals and basic cable(very limited channel selection). If you want to be able to watch digital cable you'll need either a set top box or a cable card and cable card reader(like this one).

I believe you have Windows Media Center included with your Windows version, it's probably going to be your best option for software.

HDMI to VG cable

I got myself the first HDMI to VGA adapter I could find, and once I got all the parts for my RPi connected, I found that the display on my VGA monitor is worse than crappy. Whether I use a plain terminal, the XDisplay of RaspBian, or the latest XBMC-based distro, I could not get anything useable. Until I patiently played with the XBMC and changed the actual display resolution to 640*480. Not very impressive, but it is stable.
I need to know how to change such setting for, say , RaspBian.
I want to find a *GOOD* HDMI to VGA cable that will actually work with the RPi.
Thanks

How much memory do you have allocated for the GPU?
I was looking around and here's a test someone done (full source here):
64 MB = No-HD Playback (Black screen)
80 MB = No-HD Playback (Black screen)
82 MB = HD Partially working (Some HD movies dont play)
84 MB = HD Partially working (Some HD movies dont play)
88 MB = HD Playback (seems to lag a bit)
90 MB = HD Playback <- Seems to be good. I will test it a bit longer.
92 MB = Perfectly working
96 MB = Perfectly working

The user mentioned that the optimal memory split for decent HD output was 100MB.
Don't forget that VGA is an analog signal, so make sure you don't have anthing generating a lot of interference.
If the cable you bought is of low quality, it may be and easy subject to interference.

Will try your configs

That may sound like a stupid question, but where can I change this information ? For sure I will try this before getting another cable like that, to see whether this makes a difference. As for the interference, this is also something that I want to check, like installing the minimum cabling on a clean table to see whether this makes a difference.
Thanks

If you're using any of the raspbian based distros, just ssh into it and edit /boot/config.txt using nano:
Code:
sudo nano /boot/config.txt
and search for gpu_mem and edit it.
If you're not on a raspbian based distro, shut down the pi, put the SD card in your computer and edit the config.txt as mentioned above.

[SOLVED] HDMI to VGA adapter cable
Since then, I got myself a decent monitor that actually has an HDMI input that I can use and my RaspBerry PI now gives me a perfect display, and out home TV also has HDMI input, so I guess this issue is closed (from my point of view)

Remix OS carputer build

Hello guys, I'm planning to build my first carputer. 2 years ago I have modified a tablet, Asus zenpad 8, very similar to Nexus 7 in my opinion. Now I want something more.
What I want:
Fully automated pc that works exactly like an android head unit but much better and more flexibility when it comes to external devices like an external DAC with optical output. Actually this is the main reason for not buying an android head unit, didn't find one that works very well with an external DAC. Some other things that I want from this carputer: the compatibility with steering wheel controls, backup camera, fm or even DAB radio, gps, phone calls( via bluetooth), 4G internet and so on. Many of those things are pretty simple to integrate, will talk about them later.
The components:
1. The pc - didn't think about it yet because there are loads of mini pc on the market for good prices. The only problem I'm thinking is the start up on ignition. First I wanted to go for a Remix mini pc but I don't know how could I make it start on ignition and after that automatically play the last song. If I would go for a normal PC, I found a smart PSU which has the possibility of ignition start and stop and puts the computer in sleep mode. That way I will avoid the waiting time for the boot, in fact the computer will be permanently turned on. The only problem I can think of, is the compatibility of this PSU with the android Remix OS. Is it possible?
I've tested the Remix OS and I like it, very quiq, easy to use in car with a touch screen, support all the external devices( wifi, 4g, fm and DAB, external DAC with optical output) and the launcher can be changed. I know I can opt for Windows OS and that way I will be sure that the PSU works but in my opinion windows is not so "mobile friendly", not so easy to use in car.
2. The screen: not so many to talk about, found on ebay some 9" tft touch screens, very good resolution, hdmi connectivity and USB for touch. The best thing with these screens is the AV2 input for the backup camera. The screen automatically switch to this input, has guidance lines, and this way I solved the problem with the camera. And also is quite cheap.
3. Steering wheel controls. Found on ebay the Joycon steering wheel adapter that is compatible with Android. I just have to make an initial configuration and that's it, nothing more, simply works through USB.
4. The other external devices: all of them can be found on ebay for good prices. The only thing that worries me is the bluetooth compatibility. I remember when I built that Asus zenpad tablet, I couldn't find a solution for this. Now my question is, what type of bluetooth adapter should I buy and how do I integrate this in the carputer. And I'm not talking about physical connection, I think I will need some kind of software, app, that knows what to do with this bluetooth adapter.
So, in the end, I would need some help regarding the ignition start, just the hardware part of it, all the other automatic things (launch the app and play the song) can be made with tasker very easy. Also I would need some help with the bluetooth phone calls.
Hope I didn't miss any important thing and I will appreciate any help. Thanks.

Have you thought about using a rock 64 single board computer like a Raspberry Pi that Android is really supported something like that could work really well as it has gpio outputs for various functions USB inputs for audio dacs and DAB radio and can work with touch screens or even projectors for heads up.

The truth is I know nothing about raspberry pi, heard about them but nothing more. Can you please explain a bit more? Is it possible to make it automatically turn on/off on ignition? How? Apparently that's the hardest part of the job. I've read on the internet that Remix OS doesn't work very well with stand-by function and if I'll make it to shut down completely, I'm afraid that will take too long to boot back. I was thinking about Remix mini pc and a controller that simulates pressing of the on/off button simultaneously with the ignition but it has to be tested.

So, quickly searched on google about raspberry pi and banana pi possibilities, there are some power supplies for in car use, basically they simulate a shut down from the button with a delay. That looks very good, very easy to do and also very cheap. But, how fast can boot a raspberry or banana pi running Remix OS? Does anyone know?

To make it turn off and on with the ignition, just plug it into a 12v line that is powered when ignition is on. Generally the 12v line to your head unit fits that criteria. If you want constant power to keep the device in standby mode, you can connect a relay to an a wire that is powered when the car is powered, then use the relay to short the pins of the standby button.
For boot time, you can achieve quite a bit of improvement by getting the fastest sdcard you can buy.

Thanks for advice. I've searched on youtube how android works with raspberry pi and in my opinion they don't do it very well, I mean it struggles even on youtube playing videos. So, I bought an ssd hdd, 32gb and made some tests on my pc. Found a version of android 7 special made for in car use and I'm quite happy with it until now. This android has a "special" feature, when the power button is pressed the pc shut down without displaying any confirmation message on screen. That means it will work perfectly with an intelligent power supply like m2-atx, m3-atx etc. In the next few days I'll get a new pc, micro atx mainboard so I'll begin the tests on that. Until now I've got a boot time around 30-40 seconds. Is not a bad time but I'll try to remove the unnecessary apps from startup and see what happens then. I'll post some pictures or even videos when I'll have good results. Any advice is welcome. Thanks.

I think you didn't read, I couldn't find any that works with an external sound card(DAC). My audio system is quite expensive, made for sound quality, and of course I want the head unit to be as good as possible. An external sound card with optical output I think is the best you can get.

Google search "raspberry pi alternative" theres lots of these little gadgets now adays, raspberry pi 3B is one of the most popular ( and cheapest) but there are more out there that are more powerful & better hardware.. The ASUS Tinkerboard is becoming popular as well I think I may be getting one for a streaming machine.

I've already purchased the PC and ordered the PSU. The price for all those components(+ a 30gb ssd) was under 100£ so not very expensive. Why I went for a pc instead of a single board pc? I don't know, maybe because I have no previous experience with them. Yes is true that is way much bigger than a raspberry alternative and the power consumption as well but I don't mind, maybe in the future when I'll get bored again I will try one of those pc's.
So, I've tried to install the Android X86 64bit (there is one version on internet with a patch that removes the confirmation message when you want to shut it down) on this pc with no success, all I've got was a black screen or a continuous reboot. Found out that Android X86 64bit is not so friendly with AMD cpu's. Should've search for that before buying it. Anyway, tried the 32bit version so that one works very well but I didn't find any with that patch installed. How can I remove that confirmation message when the power button is pressed?
Thanks.

first tests, quite happy with it, still lot of work to do.

ASUS Professional Dock...Best RoG Accessory

Linus did a great "real-life" usage video for all the RoG Accessories, and I agree the Professional Dock is best of them all.
Just connect it to the wireless Keyboard Mouse Combo, and you are ready for some Hi-Speed Gaming...
ASUS ADSU001 Professional Dock
- Gigabit Ethernet
- Dual USB 3.1 Type A
- 4k HDMI
- USB 3.1 Type C
Also tested on my Razer Stealth without any issues

Just FYI, By design it seems like the HDMI Output only works via the "SidePorts", specifically the "BLACK" connector, or the one on the LEFT when the RoG Phone is held in landscape mode.
The SidePorts will contain Dual TypeC, they are colored LEFT=BLACK, and RIGHT= BRONZE, ONLY USE the LEFT one for Charging, and HDMI OUT. The RIGHT Port is mostly-Likely for AUDIO ONLY
Just referencing the AirCooler that comes with the phone, that's the same arrangement

i used some other brand but cant get the mapping to works.. can tell me what game u try shows the mapping

Is that all you did with it? Because trying to run a browser on a big screen with a screen mirror is terrible when you have the status bar that's like an inch tall, and then all the fonts are ridiculously sized way too big. Basically it's useless for email or browsing on a bigger screen since it doesn't work as a second screen but just a screen mirror.

Dear Sean, I don't know which external monitor you are using, but I recommend you enable developer options on the device.
In developer options there is DRAWING, Simulate Secondary Display, and select the resolution your monitors supports. Let up know how that works out for you.
I have a Tablet, and a laptop for email, and web browsing. TBH...
In general I don't think Android was developed properly for the large screen size, and that's why it has never taken off. Samsung is trying with their DEX, but the RoG was designed for gaming on the large screen.
ASUS also offers the DESKTOP DOCK, maybe that will offer additional display options, but that was just out of my budget.
ZiCott

It's a 30 inch Dell 2k display, but I expect to plug it into any random 24inch display. There aren't really a lot of differences between the pro dock and the desktop dock, the desktop has a lot more ports and does enable a second screen experience but it's still a small screen android experience on a much larger screen, so about the same. I just decided to go the root route and get an actual Linux distro on with Linux Deploy. What it's doing, once I figured that out, is running a VM on the device and then you remote connect to with VNC from the device itself or any other device on the network. That's kinda nice because it means the VM is running in the background and you can still use the phone as is. It also means that running the RealVNC app on the device on a big screen is a lot more useful as an actual desktop environment. What it doesn't mean however is that you're running on the local Linux that actually operates the device, which may be for the better if you don't want to try running an actual desktop class window manager on Android's flavor of Linux. Good news is, it appears to operate really quickly, but I haven't yet tried to get a web development environment running on it, that's next.

Maybe I'm stupid and correct if I'm wrong but what exactly is that going to help with? It's not like I can just move over the simulated screen to the tv/monitor like you can do on a computer.

It just playing games on the larger screen, no need to tell me you're stupid, and you're not wrong. Merry Xmas

FYI I tried a 3rd party portable dock I had for my Switch and it worked (via side port) perfectly connected to my 55" 4K TV. I'm running Nova launcher and had no issues rotating my home screen to landscape. Saved myself about $100. Also had a $14 USB to LAN adapter connected. http://a.co/d/65jc58T http://a.co/d/bma6jOL

That does not need to be toggled on to play games or even to view the phone itself as it just mimics a secondary screen on the current screen only. Doesn't fix the resolution for viewing or playing either.
On a side note, for people that want to fix the giant resolution there is an app for that lol it's called secondscreen (https://play.google.com/store/apps/details?id=com.farmerbb.secondscreen.free)
You can change the resolution for a connected display and then revert back to the phone screen resolution when you disconnect, change the dpi to around 180 when your connected display is on also as there is a tablet like ui that looks better imo.

Will this accessory work with any usb-c phone?

Mileage may vary, but I have tested with Razer Phone 1, Lenovo X1, and also with RazerBlade 13", and works fine

Question: Can you sign in using a password, using the dock. Like can you type your password in using a keyboard in mouse? My screen is broken and I'm trying to get into the device.
I know this isn't where questions go but, I think the website is bugged it won't let me create a new topic or anything because "I'm not signed in" then when I click to sign it it says I am.

hello, if I use another brand dock instead of Asus professional dock or desktop dock, will the keyboard and mouse still work for gaming because Asus products are no longer sold, I couldn't find it anywhere??????

Question Second screen on NON samsung windows computer?

I would buy this in a heartbeat if someone could confirm and show me how to use it as a second screen on my Windows laptop
Thanks In Advance,
matt

You would go into the drop-down settings and toggle second screen to on. Then on the Windows laptop press the windows key + K. It will show wireless displays, select your galaxy tab. Checkmark the button to allow external inputs. You have a choice to extend the display, duplicate or have second screen only.

Windows Key + K works on my custom-built Win 11 desktop and my MSI laptop. It's not specific to Samsung-branded laptops.

Works great on Dell Inspiron 2-in-1

It doesn't work with my Ryzen 5 3550 APU.

Works great on Eluktronics 17.3 Win10 laptop.

Can't understand why it doesn't work with your laptop. This is a default W10 function and it shall not depend on the laptop's CPU. Have you managed to deal with it?

That's the only reason I can guess. My wireless card is Intel AX200, driver updated to latest. I had tried Tab S7+, S7 FE, and S8U, no one works. In the laptop window, it's showing connected but my tablet's showing black screen. Couldn't find answer any where. Thinking about using a third-party app: SuperDisplay.

I fullheartedly recommend the app SuperDisplay. I tried second screen, but did not like the lag. I prefer a wired solution, so I installed SuperScreen on the tab and the corresponding Windows App on my laptop. Now when I plug in a USB C to USB C cable (that is capable of carrying the display signal), the tablet instantly switches the mode to be an additional screen for the laptop and windows also instantly picks it up and also remembers the last configuration. Touch and pen input also work beautifully.

Same here, doesn't work on my Lenovo Flex 5 Ryzen 3 4300

I am using the app called SuperDisplay. Personally, it is better almost all aspects like support for 120Hz refresh rate, auto initialization when connected with USB. Try for yourself.

Is there cable usc c to hdmi for galaxy s8 ultra? I have a mini pc (6 core 12 threat, 16giga ram), which i have win10, win11, Linux mint with a grub bootloader.
I want to use tab s8 ultra as monitor.
I can use it as second monitor with the apps of this thread but i cant select os to boot. Also can't use Linux. Is there any app in Linux for 2nd monitor through usb?
If anyone have any kind for a cable usb c to hdmi which will work, post it.
Thanks,
