Best 240hz monitor w. lowest inputlag for competitive gaming

[daviddave1]

I am gonna sell my G-Sync 27" Acer XB272 240Hz for 300 euros cause A its to big. ( my eyes have to track to long to see enemys) and B the Gsync causes inputlag ( correct me if i am wrong please)

What 24,5 inch 240hz monitor shall i buy with the lowest imputlag for competive gaming? (mainly PUBG and Apex legends.)
I don't care about crispy graphics for eye candy. only if i can extra frags with it its good. . I only care about high FPS en the lowest imputlag possible. (PS i have a GTX 1080 GPU)

I am thinking about

ACER PREDATOR XB252Q with GSYNC disabled
BenQ XL2540
BenQ XL2546
ASUS PG258Q with GSYNC disabled.
Asus XG248Q (23.8") with GSYNC disabled. Any suggestions are welcome!!

What I’ve read on this forum Asus XG258Q should be one of the fastest. But the Benq should be up there. But the difference in input lag is that small you Will not recognize it.

I went with the Asus XG258Q as I have a monitor stand for it as the original stand is ugly!

[daviddave1]

tnx. im kinda OCD about best performance possible on the field of inputlag. if someone knows the difference plz let me know!

BenQ XL2546 is the best competitive monitor out there with its special feature called Dynamic Accuracy. It helps you a lot when you're shooting

He was asking for the lowest amount of input lag and as it seems like the Asus 25 is the best/one of the best

My 165hz VG258QR has insanely low input lag which makes me a great player in multiplayer games.
I was average gamer before that.I had 22 inch 60 hz monitor.

B the Gsync causes inputlag ( correct me if i am wrong please)

When GSYNC is used properly, it can actually improve competitive scores in heavily-stuttery games such as PUBG.

GSYNC only adds excessive input lag when not configured correctly (e.g. framerates consistently hitting the max Hz), or used in games that don't really need GSYNC (e.g. CS:GO because it always likes to run at framerate exceeding refresh rates)

Also, consistent latency can be as important as absolute latency. Proper tweaking of GSYNC can make your latency more consistent too, since there can be wide fluctuations in latency with GSYNC if you haven't properly optimized GSYNC.

It's easier to aim with "consistent stable 4ms input lag" than "varying 2ms-8ms input lag". Know what I mean? Absolute input lag is not everything. And things like stutters can throw off your aiming, to the point where adding 1ms of input lag in exchange for "removing 4ms of randomness" can actually be a worthwhile tradeoff.

The rule of thumb for esports-quality GSYNC are:
1. Have as high a GSYNC refresh rate as possible (e.g. 240Hz GSYNC instead of 144Hz GSYNC) for maximum range; 240Hz GSYNC has much less lag than 144Hz GSYNC. You want your framerate range and refresh rate range to overlap. GSYNC stops benefitting you for framerate above/below your refresh rate range.
2. Use GSYNC mainly with games that has enough stutter to interfere with your aiming (fluctuating-framerate games that doesn't stay at max Hz). That means GSYNC won't benefit CS:GO as much as it benefits PUBG.
3. Use a frame rate cap slightly below Hz (e.g. 235-237fps) when enabling GSYNC to avoid the VSYNC ON latency. Use the in-game framerate capper, and cap a few frames per second below Hz. Capping allows you to avoid the sudden lag-increase effect when GSYNC turns into VSYNC ON when framerates hit 240fps@240Hz. By avoiding the max framerate, you keep GSYNC latency consistent since 240fps@240Hz GSYNC can have 1-to-2 refresh cycles more latency than 235fps@240Hz GSYNC -- so definitely cap to avoid max framerate.

Sometimes it's better to turn off GSYNC, but sometimes optimizing GSYNC can feel like a whole monitor upgrade, too.

That said, different GSYNC monitors can have less input lag than other monitors. Not all GSYNC monitors have the same lag, and a lower-lag GSYNC "Monitor B" can have less lag than a non-GSYNC "Monitor A". The lag penalty of GSYNC can be made quite insignificant to the point where the benefits of GSYNC helps you score more frags. However, your mileage will vary depending on the games you play, and your competitive techniques.

Now, you might have trained for VSYNC OFF for years, and are used to it. It certainly feels pretty good in CS:GO and older games that runs at several hundred frames per second, with extremely minor tearing. Now, in very fluctuatey-framerate games like PUBG, there are times where GSYNC actually feels like it helps aiming (fewer stutters = less erratic aiming), but one also must calibrate GSYNC for consistency latency to avoid those latency-change effects of hitting "framerate=Hz". Now, it doesn't help everyone, and maybe turning GSYNC off is better for you, but those people who say "I feel GSYNC lag" or "GSYNC hurt my scores" sometimes ends up meaning they didn't adjust GSYNC correctly.

The Right Tool For The Right Job!

tnx aloth man. appreciate it.
