I'm not so sure I get the whole DPI subject, I thought DPI referred only to the "printed resolution" in other words , that DPI is the same as PPI but you talk about DPI from printed things and PPi for digital things, am I wrong?
The nexus 6 comes with a stock value of 480 DPI and if I want to have more space available when I'm using chrome, so I can fit more text on the screen I should lower it, but by doing it am I reducing the quality also?
I'd appreciate your input on this :laugh:

DPI refers to androids scaling where as PPI is the physical amount of pixels per inch on the screen so a lower DPI makes things be smaller on screen (which is what you want) where as higher makes text and things larger.
Also, stock DPI on the nexus 6 is 560 where as the PPI of the screen is 493. Personally, I like 520 DPI as its smaller than stock, but not so small that you can't see anything

Thanks for taking the time to explain [emoji57] , and every android uses 560 dpi as default ? What do manufacturers take into account when choosing the DPI, only the screen size ?

Nah, just the n6 uses 560 that I know of. It all comes down to personal preference on what you like.
When a manufacturer chooses a DPI they look at no only screen size, but resolution of the display because as PPI goes up DPI needs to as well

Not necessarily. Generally yes - but with big screens at higher resolutions, they may want to opt for more screen real estate than maintaining a proportional ratio to smaller screened devices.

There is a lot of confusion and misinformation about this subject.
Fact is, that PPI and DPI are actually synonymous.
One pixel is one dot. Hence the number of pixels per inch is the same as the number of dots per inch.
The "standard" DPI/PPI resolution for Android is 160. It is so because the first Android device, the HTC Dream, was physically 160 DPI.
Now the way it works in Android, is that the SOFTWARE needs to be made AWARE of the physical resolution of the screen. This is why the build.prop file often has a parameter "ro.sf.lcd_density". This is the DPI/PPI value for the physical screen.
The kernel tells it what the overall resolution is, in the case of Nexus 6, 2560x1440. Knowing the DENSITY, and knowing the overall resolution, you can calculate the physical size of the display.
The reason why this information is necessary, is to be able to SCALE things -- text, UI elements like buttons, images -- such that they take a proper physical space on the screen. I.e., if you have a font size that displays with a character height of 1/3 inch on an HTC DREAM, then using the same number of PIXELS on a Nexus 6 would result in a character height of 1/10 inch, i.e., too small to actually read.
So instead, the fonts/UI elements/etc. are sized using something referred to as a DiP -- Density independent Pixel. This is, basically, 160 dpi. So what it does, is it SCALES everything into NATIVE pixels by the ratio between ro.sf.lcd_density and 160, so that things look the same size on the screen, and you are actually able to read it.
Now, it is technically incorrect to screw with the value of ro.sf.lcd_density, since this will convince Android that the screen is larger or smaller than it actually is. However, some people like a tighter or looser UI, so it is there in case they want to tweak it... within reason.

So basically a device like the nexus which has a 1080p 5" screen has a 445 PPI and a 445 DPI and the nexus 6 has a 5.96" display which is 493 PPI and 493 DPI, I just get confused for example because on a macbook pro retina you get a resolution which is greater than QHD but still get a "working space" of a 720p display and I assume it has to do with the DPI
hey,
what is the max resolution that can be achived with dex on a highres monitor?

1920x1080 is both min and max res
Hi,
K20 pro got 81 hz display mod from our beloved xda guys.
Are we NOTE 8 guys getting any such mod? It will be awesome.
Thanks
I believe that the Note 8 only has a 60hz display. Overclocking the display would probably kill it.
Im looking for a Native 10 bit QHD Oled phone panel with atleast 510 ppi 6,7 inch screen size.
I came at the OnePlus 8 Pro the Oppo Find X3 Pro and Xiaomi Mi 11.
The X3 pro is 200 euro's more costly then the oneplus 8 and the xiaomi about 130 euro more.
I had thought the mi 11 had dolby vision but maybe this is only for thexiamoi ultra and the mi 11 Lite?
Seems strange if the base model wouldn't have it but the lite budget version would.
The ultra version doesn't seem to be sold anyway in my country (holland)

I have the Xiaomi Mi11 and find it fantastic it may not have Dolby vision but it has HDR 10+ 6.8" screen with 1500nits peak brightness, very smooth 480htz sampling and 120htz screen. The sound is amazing for a phone, great camera's and an IR blaster to annoy your friends Down the pub when you turn the TV from footy to a soap. But the choice is yours.

Yes aside from dolby vision the other stats seem perfect.
So what you are saying is only the ultra and the lite version have dolby vision?
@6:22 video color enhancer SDR to HDR technology
@6:25 video image sharpener
@6:35 bright HDR video mode
Do you think the xiaomi mi 11 have similiar options like this?

I would say they're both similar just did a side by side comparison on GSM Arena and they are both good, and yes the mi 11 does upscale any videos.
The screenshots you send. Thanks!!! by the way!
1. Seems to do with motions
2. HDR AI enhancement.. I suppose this is only for HDR content
3. Upscale videos that are not native ress to native ress I suppose
Number 3 might be the same as the " video image sharpener" in Oppo
However for SDR to HDR technology and bright HDR video there does not seem to be such option. Now maybe bright HDR video option might not be needed since the firmware already does what it needs to do in a way it lieks or something i dont know.
But the SDR to HDR technology seems really interesting to me. Especially since I will be streaming my desktop to my phone alot. I don't know how useful this is. but if it isn't on the xiaomi 11 might be a shame idk.
Just found this on the oppo site hmm
The O1 Ultra Vision Engine supports Video Image Sharpener and Video Colour Enhancer features, which are implemented only for certain adapted apps.
The Video Image Sharpener is available for Photos and YouTube, whereas the Video Colour Enhancer is available for YouTube.
"You can only enable one of the functions at one time."
Doesn't seem to help with moonlight streaming then I suppose.
Also I see there is an option "enhanced countours",on the Mi 11X though.

The first time I saw a hdr video on the mi 11 it seems to be very bright but does not have very wide color gamut, so I tested it with my colorimeter . when playing a hdr video it switches to profile that able to get very bright, I think for a medium patch around it measured 1000 nits but the color gamut measure only 83 precept of dci-p3. It not very bad as the high brightness give a perceived look of a more saturated color. When you are on sdr mode, there are very good color profiles. The original color color mode target a SRGB(99%) .It has very low de 2000 and have good white point. You also can change the white point. The p3 color mode target dci-p3(95%).The average of de2000 1.3 ,max 2.9.It does not support hdr as it will switch automatically when watching a hdr video. Also, the dci-p3 mode does not allow very high brightness (not an issue as you won't need it on sdr ). As you lower the brightness you start to crush black on dc dimming, when not on dc dimming it switch the pwm frequency and does not crush blacks until quite low brightness. You can switch to 90 hz mode, and it won't crush black on dc dimming but has green tint (worst while display a gray color), you can change the white level to reduce it . The display has a Diamond sub pixel arrangement and not rgb but still very sharp because of a very high resolution. It is much sharper than a full hd oled with Diamond sub pixel arrangement . I really like this display.I use original color mode with 90 hz . For me, a display that do not crush blacks looks so much better, especially for watching video. I saw so many phones with oled screen that crush black and look not good.
Note 10 Pro has 1200 Max peak Brightness and almost 100 DCI P-3 But it's only 8bit panel. Can it look better than SDR?
HDR is the one that you wanted... especially for movies and accurate color rendering.
8 bit ain't cutting it. The dynamic range is too limited to give accurate greyscale and color reproduction which also skews the gamma to hell.
All variable refresh rate displays are very difficult to accurately color calibrate. It's their Achilles heel. The N10+* has one of the best (maybe the best) color calibrated displays, even now. One of the reasons it's still my device of choice.
