I've contacted Samsung here in Canada 3 times now, each time they deny me speaking with someone from Technical Support, instead my only options are Customer Service or their respective Manager(s). I've offered to document the exact issue, to provide any details and testing with the hope of engaging Engineering of some sort. The best the Manager could suggest was to set the PS4 Pro or PS5 to RGB Limited... SMH (obviously this had no impact at all and predictably muted the colours). They are now insisting I have the mainboard replaced by a 3rd party, so they can rule out their "Step 1", before looking deeper into a possible software issue. This is after explaining to them and confirming the following:
ONLY when you enable Game Mode , (with Game Motion Plus disabled) can you see visible rolling scan lines. I can observe this on the PS4 Pro, PS5, and SNES Mini (so far). All other Picture modes do not suffer from rolling scan lines, nor do the internal apps like Netflix or YouTube.
However, with Game Mode enabled and Game Motion Plus enabled, these scan lines disappear.
The problem is, with GMP you add input lag which defeats the purpose of this TV; to buy a gaming TV with the lowest input lag. I'm not sure visible scrolling scan lines is an acceptable trade off for low input lag.
And now we hear of so many others reporting the exact same issue, this time with the XBOX SX & VRR enabled.
Oddly enough, i do not have this issue with the Nintendo Switch at all. Its the only console I can have Game Mode enabled, GMP disabled, and no scanlines at all. Input lag is excellent as you don't need GMP to hide the scanlines.
Like many others, it goes without saying I've tried a plethora of different HDMI cables (including a fibre optic HDMI to rule out interference), tried all HDMI ports, different TVs, even different rooms to rule out power interference.
