Beware that the amdgpu kernel driver currently has issues with GPU scaling, see
bug 95131.

I'm very tired. I need to take a break. Even the native resolution for my
laptoop and the monitor im using arent available with the opensource driver.
Thank you for your help.

Also trying to adjust the scaling mode from the default of none gives me a
blank screen, regardless of wheter i have underscan set to off or on with the

Yes that's correct, catalyst doesn't see the 1366x768 either but it does offer
me other resolutions which are useful to me and i would like the same available

so what can i do? Catalyst/fglrx has some notion of it in spite of the edid
not reporting all it's modes. How does catalyst do that when the opensource
driver can not?

Turn off underscan if you want to use scaling. Also, underscan compensates for
overscan applied by the TV so you'll end up getting scaled twice (once by the
GPU and once by the TV).

You know what's funny is that i have seen the specs for the tv and see that
1366x768 is the default resolution for the tv. Also for this laptop that was

When the system boots, it boots into 1920x1080. if i use then the xrandr to
set underscan to on the desktop size is still greater than the viewable area.

the open source drive default scaling mode is none.
Also catalyst uses 30hz not 60hz for the resolutions above 1280x720 and when i
tried to use those with the opensource driver i get a

The TV does not appear to support 1600x900. I think catalyst must add it as a
"fake" scaled mode. You can enable scaling in the open source driver by
setting:
xrandr --output HDMI-0

Also when i used graphics scaling with the catalyst i had to set underscan to
7% at 1600x900 30hz under maintain aspect ratio.

Also i went back to the catalyst driver to see what it does differently that i
haven't tried and it uses for 1600x900 a 30htz refresh rate but also it uses
monitor scaling and not gpu
