I use the AW2723DF (1440p, 280hz Overclocked Monitor, updated firmware/drivers) and for years, the input lag I experience has been inconsistent. I tried many different things to diagnose the issue over the years: graphics card drivers, Nvidia Control Panel tweaks, ReBAR, Process Lasso, etc. It's been bothering me so much that I've started looking into how to get or build an LDAT for myself just to be able to confirm the latency change. I've since reset my drivers and settings back to default settings.

Partially due to this, I think I've finally narrowed it down to being a monitor-related issue. For whatever reason, G-Sync would sometimes turn itself on in the NVCP upon restart. This monitor has no OSD setting to enable/disable G-Sync, so it all must be done in the NVCP. Because my main game Overwatch 2 was locked at a frame rate (300 FPS) above my refresh rate, and I didn't want to use G-Sync in the first place, I had the Monitor Technology setting for OW2 and other games set to Fixed Refresh. But now that I've gone back to the default settings, things have changed.

In order to fix my heavy mouse/input lag issue (and this is repeatable), I essentially need to turn G-Sync on and off again. I've got theories as to what's causing this but that's why I'm making this post. I don't really know. I wonder if the monitor is turning G-Sync on or off on its own in the background, I wonder if the displayport cable isn't able to handle the data, I wonder if it's just the way G-Sync is implemented for this monitor?

I'm confused. I've turned off G-Sync in the NVCP, The G-Sync Compatible Indicator shows that G-Sync is not active, the OSD's Framerate setting shows that G-Sync/VRR is not active, so how and why does it matter that the G-Sync Compatible Monitor Technology setting is on or not? Shouldn't the latency be the same as the Fixed Refresh setting if G-Sync is disabled and the FPS is above the refresh rate anyway? Does anyone have any familiarity with this issue or this monitor? Does anyone know how this could happen? Thanks to anyone who responds. In the meantime, I am replacing my DP cable just in case but I doubt that will change much.

gsync called freesync in setting on your monitor

gsync called freesync in setting on your monitor

I don't have any Freesync setting in the OSD if that's what you're saying.

I've been researching this issue as it's repeatable and so strange to me and I've found a thread detailing the same issue: viewtopic.php?t=7284

Coincidentally, it is another Alienware monitor, this time the AW2720HF The OP, Arx, says:

But after switching between G-sync on and off, I kept getting the same feeling that enabling G-sync boosts my performance in Aimlab, even though I am 100% sure the G-sync is not affecting the refresh rate of my monitor.
(My monitor can display the current refresh rate, and if VRR is active, the displayed value will change dynamically. It shows 240Hz constantly, so the G-sync is not affecting refresh rate)

This is exactly what's going on with my AW2723DF. Despite G-Sync not functioning (VRR not active, G-Sync Compatible Indicator not present, etc.), it still affects the latency of the monitor. I know it's a sample size of two, but if it's an Alienware/Dell driver bug, how do I contact those that need to know? As most know on this forum, it is insanely frustrating to not know the source of seemingly random input latency so having the monitor be the issue without it being pointed out anywhere is insane. Seriously think AW G-Sync Compatible monitors should be tested for this, at least the AW2723DF and the AW2720HF. Glad someone else has been experiencing the same thing just so I know it's real and happening.

I have the alienware 360hz qd-oled and I turned gsynce on and I went 40/10 three times in a row because of how responsive and quick it felt. But it feels like it gets worse and worse the longer I have the game on. I try not to alt tab as well. I genuinely don't know what it is that is causing this off feeling for me since I got my set up with a 9800x3d. I haven't enjoyed playing competitive games since april and I've done every single thing you can think off to have that normal feeling back. I've played around 1500 deathmatches since the summer trying every possible setting that can be changed from windows to bios to peripherals.

So you have the AW2725DF and you're experiencing the same issue. For me, it was the same. I got my AW2723DF and the input lag felt worse than my previous monitor but I stuck with it thinking the problem was something else, sending me on an insane wild goose chase. I'm certain the issue is related to the G-Sync/Freesync implementation. That's a third Alienware G-Sync Compatible monitor showing these issues.

I don't know why it happens, but here's what has helped me step by step:

I have made it so my monitor never turns itself off/goes to sleep which alleviates it. It seems like whenever the monitor turns off, it resets whatever causes the input lag for me. This is something you probably can't do with an OLED unfortunately, which is why this issue needs to be addressed. Open the Nvidia Control Panel, click Display, then click G-SYNC Compatible Indicator. This just shows you when G-Sync is actually functioning. If the input lag is terrible on boot, I open the NVCP, go to Set up G-SYNC, and check "1. Enable G-SYNC, G-SYNC Compatible," then check "3. Enable settings for the selected display model." I hit Apply. The screen should flash. Uncheck number 3, hit Apply again. Another screen flash. From here, you can uncheck box 1 as well and Apply again but either way, the latency drops for me. Throughout this process, I have the Frame Rate Game Enhance Mode in the OSD on to make sure G-Sync isn't actually activated.

I don't know if all of this is necessary, I don't know why it happens, but this is what helps me sometimes. My initial guess was that some mechanism of G-Sync/Freesync would turn itself on/off in the background, whether you changed the settings inside of NVCP or not. Perhaps forcing the setting on or off yourself forces that mechanism to reset to what you've set it to. In other words, it feels like there is some sort of driver issue with the Freesync implementation that's adding noticeable latency at seemingly random until you reset these settings yourself. I want an actual answer so I don't have to theorize or describe what it feels like in this way which is why this post exists. I hope someone knowledgeable in this area sees it.

If you're looking for help from someone knowledgeable, this forum isn't the place to look. I have an important question: after you've performed your tricks, is your gameplay 100% stable throughout the entire session, or does it get worse over time/after restarting your PC?

Maybe try force disable in NVIDIA inspector

Not much of a trick, it's really just enabling/disabling G-Sync until the input lag is gone. But yes, once it works, the input lag is gone and stays gone until my PC restarts or the monitor goes to sleep/turns off. It makes me fear restarting unfortunately. I'm glad that something actually works and in such a repeatable way, but I don't like that I have to fiddle with G-Sync settings to have my monitor work the way it should. I also don't like how it seems randomly applied so when I boot up my PC, I never know what I'll get. It genuinely feels like the G-Sync setting is independently affecting the input latency without G-Sync (VRR) actually being enabled, exactly how the thread by Arx describes. It seems like there's some underlying, obfuscated setting that can add input latency yet there's no way to know if it's on or not until you turn G-Sync on/off yourself. Surely that's not intended behavior.

I did try this and it didn't work but that was a while ago. Thank you for the reply.

powen on pc, dont touch anything, download cru, open restart64.exe, it restart your gpu driver.
tell me result about game.
