yes he have but the overdrive feels fast in start but in other day its feels lazy ELMB makes overdrive more worse but less motion blur could be add little input lag to cause mouse movement worse on elmb i suggest if you take the xg248q use adaptive-sync and overdrive 3-4 to get much better gaming experience


I think you might refer to when the monitor is cold right? Because overdrive tends to get better when a monitor is hotter!

99% of FreeSync monitors do not support "variable" overdrive, which causes the issue you are describing when using VRR. All genuine G-SYNC monitors contain an actual hardware module that performs variable overdrive adjustments during VRR operation to prevent this issue.

As for the new "G-SYNC on FreeSync" driver feature for Nvidia GPU VRR use on FreeSync monitors, there is almost a zero chance Nvidia will ever add variable overdrive support, as it's extremely difficult to accomplish solely with software, a reason why 99% of even FreeSync 2 monitors paired with AMD GPUs don't have it either.

For LCD-based displays, variable overdrive is one of the biggest (and most overlooked) advantages of hardware-based G-SYNC over software/cable-based FreeSync.



Now I see why the overdrive gets so bad at lower framerate!

But im confused again, on the other thread you mentioned even if I drop to 160fps + gsync on a 240hz Im still at 240hz? I notice very well how this Asus XG248q struggles so much at lower Hz.

To take the best from this panel I need to sustain constant 200-240fps and thats very hard with current day hardware. Man I love the 240hz low input lag and motion clarity but I still think it is really early to take the best out of it. Even 9900k 5ghz struggles keeping up, unless Im playing CS or Overwatch. On battlefield V, black ops 4 or quake champions is a no go. Plus when CPU and GPU are close to 90%-100% usage the input lag is higher and takes away some 240hz advantages.

Would someone call me crazy if I said that Viewsonic Xg2402 (fastest 144hz monitor only 0,4ms slower than Benq xl2546 240hz according to rtings and amazing overdrive) + 141 fps lock no VRR (60% cpu usage + 60% gpu) provide a similar lag free experience to 240hz on a modern game engine? That's exactly what I feel! Lol

never tryed the viewsonic but i will compare the xl2546 to the xg248q in the next days, anyone with the asus can tell me if the monitor has color vibrance and black eq setting (that is avalible while i use elmb?) would help me out a lot. I dont think i will order the xg248q if he is missing this settings.

It has those settings yes but I dont know if they are available when on ELMB because I never used ELMB. I am very sensitive to flicker and in 30min I have massive eye strain and pain in the head so I avoid any form of strobing. But when I come home I can try it for you.

Because it's a different subject from overdrive (apples vs. oranges), which has to do with how much the pixels smear/ghost on LCD due to lower pixel response time when compared to display technology such as CRT and OLED.

More motion blur/ghosting doesn't necessarily increase input lag like lower framerates or delayed frame delivery do from certain syncing methods. With poor overdrive, the frames aren't delivered slower, they're just blurrier.

As for my reply to you in the other thread, I'll try to clarify whatever you still don't understand there (just to keep things properly separated).

Have you tried disabling overdrive? If that's an option in the OSD, try disabling it. This might actually improve things. TN panels are usually fast enough to still look OK even without OD. The increase in blur might be better than an increase of OD artifacts.

bumping this thread because I had the same question about which monitor is best?

which of these three has the best strobe based blur reduction?

which of these three has the best panel image quality with strobe based blur reduction on?

which of these three has the best contrast ratio and brightness with strobe based blur reduction on?

Which of these three has the lowest input lag with strobe based blur reduction enabled?

Hi.

Is not the XG248Q supposed to be inferior to the XG258Q?

In any case, I will stay here and investigate which is the best, whether the XG258Q or XL2546, mainly for professional use in fast response games (Quake, Apex, competitive Battlefield), at 240Hz-240fps. Especially considering that the GPU is an AMD (Radeon VII).

Thank you.

A cordial greeting.
