view screen Tab 3 7" to my tv with cable

Hi guys, I need to project the screen of my Tab 3 7" T210 on a TV that has both the hdmi connection that the usb.
I bought a cable network which on one side has HDMI and the other has both USB (to connect to the TV or phone charger) and micro USB to connect the phone precisely.
With the galaxy note 4 This cable works great, but with the tab 3 7 "does not go .... the tv says no signal, while the tab is not even the micro USB connection sound.
There is of special cables that "force" the screen projection of this tab on the tv?
Or maybe something universal that can be projected on the TV screen of any device?
Pretty sure the tablet has to have specific support for the feature. I'm not sure if the tablet does, but from the looks of it it doesn't

T-505 Galaxy Tab A7 USB OTG and charging at the same time, is it possible?

Hello all,
I plan to use the Galaxy Tab A7 as a Car Tablet.
Therefore I bought a USB C Hub with Audiojack and Powerdelivery.
Unfortunately it somehow does not charge over the USB Hub. The hub itself works, audio can be played through the jack and it recognizes the USB Sticks connected throught the hub. Is it something which can be solved by changing the software / Android Version or even flashing a custom Rom?
On my phone the hub works flawlessly.
Btw: Does anybody have any tips for setting it up as a car tablet? I already installed some OBD apps and a car launcher.
I use the Torque and Car Launcher in Splitscreen mode and use maps as a floating app on top. Further tips would be appriciated

Question Second Screen not showing on an external monitor.

I have a laptop that is connected to my Galaxy Tab S8 Ultra via "Second Screen", but when the "Second Screen" is in the foreground of the tablet it does not show on the external monitor connected via USB-C to HDMI cable.
I thought second screen is for wireless only?
I ended up buying SuperDisplay, that $15 is worth it, I've tried Duet, Second Screen etc...
My setup is mya laptop is cast to my Galaxy Tab S8 Ultra via "Second Screen" then my Galaxy Tab S8 Ultra is connected to an LG Monitor via USB-C to HDMI cable. The laptop screen is ok on the laptop but not showing on the LG Monitor.
