Environment: -------------------------------------------- Kernel: (drm-intel-next-queued)8f588cfc349bbbd8ae62a13679b9efba41645064 Author: Ben Widawsky <ben@bwidawsk.net> Date: Wed Jul 17 12:19:03 2013 -0700 drm/i915: Create VMAs Bug detail Description: -------------------------------------------- We bought a new SKYWORTH 50E780U 50" TV which supports 3840x2160. I tested it on our HSW desktop and found that some modes can't show competely on the screen. I take a picture of this and attach it in the attachment. And I will attach the whole boot messages too. Here I list all of the HDMI modes and mark the wrong modes as [not full].

Isn't that just overscan?
Yeah, we still need to fix our overscan hint implementation to dtrt in the infoframe headers ...
As far as I can tell, this TV doesn't support underscanning CE modes, so we'll need to play with the panel fitter here. To use the AVI infoframe to tell the TV to overscan CE modes (to be compared to IT modes) I think you need sink support to do that and the EDID tells you if it's possible or not. For that TV, I isn't.
Created attachment 89914 [details] Gently ask HDMI sinks to underscan Cancan, could you try the attached patch to give the sinks an underscan hint?
Created attachment 89936 [details] dmesg of TV mode test with patched kernel I added the patch in the latest drm-intel-nightly kernel.But some modes still can't show completely on the screen.

To clarify, Cancan has completed her internship and left Intel. Now Qingshuai will follow the QA work.
