Any resolution at 75hz. My FullHD modelines are:

[   802.898] (II) AMDGPU(0): Modeline "1920x1080"x0.0  148.50  1920 2008 2052
2200  1080 1084 1089 1125 +hsync +vsync (67.5 kHz eP)
[   802.898] (II) AMDGPU(0): Modeline "1920x1080"x0.0  170.00  1920 1928 1960
2026  1080 1105 1113 1119 +hsync +vsync (83.9 kHz e)

First one is 1080p at 60hz (good), second is 1080p at 75hz (flickers)
