From f0602b709985b28bc8ce572d6c517d9c26669735 Mon Sep 17 00:00:00 2001 From: Satyeshwar Singh Date: Tue, 16 Nov 2021 14:11:03 -0800 Subject: [PATCH] edid: Added support for 4k@60 Hz monitor Previously, the large modes (>1080p) that were generated by Qemu in its EDID were all 50 Hz. If we provide them to a Guest OS and the user selects one of these modes, then the OS by default only gets 50 FPS. This is especially true for Windows OS. With this patch, we are now exposing a 3840x2160@60 Hz which will allow the guest OS to get 60 FPS.
