The OLED range are not being sold as gaming monitors though. The motion looks fine to me, as someone who has come from a world of plasma-owning. No trails or smearing. You get typical 24fps judder during films, unless you engage TrueMotion, but on the whole, this notorious 'motion problem' is a myth being spread by people who have either no experience with them, or have only seen them in-store, set up incorrectly.
Yes, OLED has great response times so you don't get trails or smearing.
The problem with OLED is motion blur.
Anything moving quickly across the screen becomes a complete blur because they don't flicker at all.
That's why they have 0.1ms response times but only 300 lines of motion resolution in tests.
It's the same problem LCDs had years ago before they added black frame insertion and impulse backlight modes.
Easier said than done, brightness will take a nosedive and unlike LCD that can just flicker the backlight to hide pixels switching the OLED needs to go from picture -> black -> picture flawlessly. And pretty much requires a panel that can work at 2x the input frequency
That's exactly what you need to avoid.
If you refresh at 2x the source framerate, everything becomes a double-image when it moves across the screen.
Refresh rate has to be equal to framerate.
The other thing that LCDs can do that OLED cannot is overdrive the backlight on the strobe impulse. This would hurt the OLED panel immensely.
The thing with OLED is that it can get quite bright when you light up a small amount of the panel, but dims a lot when you light up the full thing.
With the B6 that is 800 nits for 10%, and only 150 nits for 100% of the screen.
So you wouldn't need to overdrive the panel.
What you would do with is scan the image like a CRT where 10% or less of the screen is lit up at once, instead of strobing the whole screen on/off.
800 nits with a 10% height scanline would give you 80 nits brightness - a little bit less than the SDR spec of 100 nits.
If the new panels can do 1000 nits this year, you could meet the SDR spec while improving motion blur 10x.
So, if you could try setting Clear all the way to the max, I wonder if the Z9D does have backlight strobing in Game Mode when you do this. If it does, you will immediately notice the flickering of the image, much like an old-school CRT.
Unfortunately I think Sony removed the 60Hz Clear mode from all their new TVs and they only refresh at 120Hz now.
