Hello,
I recently got the new build of Ps4gentoo installed on my 5.05 ps4.
The issue I'm having is that the edges are cut off on my screen.
I've played with my TV settings like crazy but none of them are helping in this situation.
I had the same issue when I hooked up a windows pc rig but was able to fix it using settings within windows.
Is it possible to compensate for the overscan within Gentoo.
I'm a complete noob when it comes to Linux so any help would be greatly appreciated.
Thanks!

does this only happen with the ps4, or other hdmi inputs as well? i recently had to use the service menu on my tv to fix some erroneous overscan affecting the bottom edge of my tv when using composite video. if it affects all hdmi inputs i'd probably do it at the tv side.

a ps4 would be using a radeon card i believe, do you have the catalyst control panel installed?

cheers

Thanks for the reply! This only seems to happen when running an OS on this tv. It's an old 2008 vizio fat back tv. Unfortunately it doesn't have the proper options to solve the issue within the tv settings. I'll look into getting the radeon software worked out!

turdbundy,

In the days of analogue TV, overscan was common. From a user perspective, its better to crop the image all round that to show black borders.
Most TVs with digital inputs have an overscan adjustment.
Turn it off on the HDMI inputs.

With digital sources, overscan is not required. Indeed, it should be avoided, so you get a 1:1 pixel buffer to pixels on the screen mapping.
Rescaling digital sources can lead to some ugly video artefacts.

If you're using the radeon kernel driver, try booting with the HDMI sound disabled (radeon.audio=0).
