Has anyone been able to validate this on other SoCs? I guess that's 
still the main concern - empirically I've found that clock rates that 
work perfectly on RK3399 can be glitchy on RK3288 to the point of being 
barely usable, and can result in no display at all on chips not using 
the Synopsys phy, like RK3328, where the HDMI driver considers the mode 
valid but later the phy driver is unable to match it.

I don't have access to a QHD display to test this myself; I've only 
played around with weirder 4:3, 5:4 and 16:10 modes on PC monitors.

Robin.
