I have a Windows 8.1 Tablet with an Intel Atom Z3735F SoC. This has an integrated Intel HD GPU.
The tablet has an micro HDMI port at which i want to attach a tv.
But on the tv i only get a signal with an huge overscan (black frame around the screen).
I checked the reason for that: my tablet runs at a resolution of 1280×800 which is the same resolution i selected for the tv (hdmi port). But the tv says it gets a 1920×1080 resolution. And in this HD image is the tablet screen centered.
I tried multiple configurations and settings, but the only way in which i get a fullscreen image on the tv is when i set 1920×1080 as a resolution. Which is bad because i can't use the tablet screen in full hd.
I already un/installed the newest driver multiple times.
I also tried this solution:

but the customModeApp will not work with the newest drivers anymore.
I have searched the intel forum for hours, where multiple pepole reported the same issue. Unfortunately without an real solution.
So you guys are my last hope on getting this issue fixed.
Has anyone an idea how to solve this problem?
Thanks.

I can confirm that most resolutions will display a centered image with black borders on all sides. I connected my Z3735F Chuwi Vi8 tablet to a Samsung and an LG television. Only on some resolutions you can select "Maintain display scaling", which will remove the black borders on your TV.
Resolutions that work for me are:
The 1280 × 720 resolution allows me to mirror the display of my tablet (1280 × 800) to the TV, losing only 80 pixels.
To set the "Maintain display scaling" option do this:
Alternatively,
If the "Maintain display scaling" option is not there, you will have to select a different resolution and try again.
