Is there any information about the backlight configuration for these two models and whether or not it can be disabled?
Guessing these will be the typical edge-lit fare with only 8-16 zones where poor implementation (game / movie dark scene flickering, subtitle strobe effect etc) can ruin the ability to actually use them in HDR.
Just read over the specs - 1000:1 contrast on both of these panels is shocking low for a monitor targeted at creators?
