The 480Hz Tour De Force, Chef's Masterpiece: 480HZ OLED PURSUIT CAMERA

Can anyone hypothesize what the input lag would look like w/ 240hz ELMB? Could it still be competitive in esports? Assuming it’d be much better than 120hz ELMB.

I estimate the chnace for it to be a problem at 0,00%.

120Hz backlight strobing is already OK with v-sync OFF.
120Hz backlight strobing is laggy v-sync ON, but much less laggy than 60Hz.
240Hz backlight strobing should be usable even with v-sync ON, although you'd still be better off using v-sync off for score-focused gaming. I see no reason why any monitor manufacturer would screw things up so badly that it would give some super stupid amount like +20ms. 240Hz full frame cycle is 4ms, so the backlight strobing itself will have close to zero effect.

OLED does not have a backlight, so you have to use BFI / multi-refresh techniques.

There's some special considerations with OLED BFI only working up to half OLED max Hz on many OLED panels that do not have two-pass pixel refreshing per refresh cycle...

Only a few OLEDs (e.g. LG CX, Oculus Rift, PSVR2, etc) can do a double-refresh per refresh cycle (once to turn on pixels, again to turn off pixels), allowing sub-refresh BFI at max Hz.

Has there been input lag test done about this? (LDAT/ high speed camera/reflex equipped monitor/...)

I mean, it’s not that hard to test yourself since there are monitors like the XG27AQMR that let you toggle it on and off in the OSD. This is something you don’t need any fancy machinery to test because the difference is pretty noticeable toggling back and forth where you’re definitely going to like how it feels better off.

Blurbuster man says it might just be bad implementation but I think it’s an inherent DSC problem since the behavior is identical on every single monitor I’ve tried with it. As for actual measurements, it’s slightly anecdotal, but the HP 27QS and LG 27GR83Q-B both use similar BOE panels with the HP not using DSC while the LG does. RTINGS reviewed both and the HP has lower input lag. Don’t think anyone has actually benched it on and off on a monitor like XG27AQMR. It’s not something I personally need to bench as it feels unplayable turned on to me.

So my prediction is that you will see people in the competitive scene either fail to adopt new monitors like the Asus 540hz at all, or the people that do use it will probably underperform. And this will be the first sign of time for engineering to go back to the drawing board.

Hello roach

If the bottom line is that dsc is shit and most new oleds will use it

Can you name a good monitor for competetive games?

Should I consider benq new xl2546x/xl2548x?
Or another model that already exists and available!

Im using very old tn 144hz and want to upgrade

I’ve tried like 10 monitors in the last two months and each one either has 1). INSANELY HIGH EYE STRAIN 2). Sluggish cursor movement or 3). Both.

There’s a very high chance whatever you buy will be worse than what you already have (144hz TN panels aren’t exactly slow).

for now I'm keeping my old benq 144hz tn. it got some issues going on for it but it does the job
I'll wait to see what 2024 will bring to the table and hopefully I will find my "endgame" later this year
