so you got this issue only after ASUS ROG Strix OLED XG27ACDNG purchase? or it was like this even on previous 144hz?frmslf4 wrote: ↑16 Feb 2026, 17:15Hey guys,
I’ve had the ASUS ROG Strix OLED XG27ACDNG(MCM105 firmware) (1440p / 360 Hz) for about 8 months, and only recently I realized something is seriously wrong with the way it behaves on my setup.
For months I kind of assumed “maybe that’s just how it is”, but I’m coming from 144 Hz and I know what proper smooth motion feels like(5k hours in competitive shooters). With this monitor, even when I’m sitting at 300–360 FPS, it often doesn’t look or feel like true 360 Hz. Motion can feel oddly choppy and inconsistent, and the input lag feels heavier than it should for this level of refresh rate and FPS.
What finally exposed it was a completely random experiment. While I was in-game(Escape From Tarkov), I went into the OSD and changed something in Aspect Control. The screen flickered black a few times, and it felt like Windows/NVIDIA suddenly re-detected the display. My NVCP settings reset, and the whole display pipeline felt like it restarted. After that I did an OSD factory reset, and that’s when I experienced the “holy sht” moment: everything suddenly felt exactly how I always expected a 360 Hz OLED to feel. The motion was insanely smooth, the input lag was basically gone, and mouse movement felt extremely light and responsive. I honestly thought I had fixed my “problem” and that this was the normal state I should have had from day one.
But it didn’t last. After a short time, sometimes a couple of minutes, sometimes after a few games - it drops back into the bad state. Same FPS, same settings, but it becomes less smooth and the input lag feels worse again. The weird part is that when it’s in the bad state, even YouTube gameplay, obviously limited to 60 FPS, can look more consistent and smooth than what I’m seeing on my 360 Hz setup. Like literally. And when the monitor is in the good state, it feels like watching that same YouTube video, just with way more frames. I know it sounds ridiculous, but this is my experience.
The most frustrating part is how reproducible the “temporary fix” pattern is. If I force some kind of re-handshake or mode rebuild, the monitor often snaps back into the good state for a moment, then slowly falls apart again without me touching anything. OSD factory reset has triggered it before. Switching refresh rate in Windows/NVCP (like 360 → 180 and back) often triggers it too(not anymore). Sometimes changing resolution used to do the same thing. Toggling VRR in the OSD can also bring it back temporarily. Toggling G-Sync or V-Sync (driver-level) has similar behavior, and I’ve seen this exact “state drift” thing before in PUBG as well: I’d get a moment where everything feels locked-in and perfect, then later it feels heavier again, and toggling G-Sync off or on would randomly bring back the “correct” feel… temporarily. One time i switched all settings to ultra in PUBG, instead of my normal 350+ fps I got 200 something, but man was it smoother, and felt exactly how it was desighned to feel.
For context, my usual setup is borderless (fullscreen doesn’t help; borderless used to be perfect when it “worked”), HDR is always off, G-Sync is enabled per-game, V-Sync is enabled in the driver (not in-game), Ultra Low Latency is set to Ultra, and I’ve been using RTSS with a 353 FPS cap the whole time. I’ve tried turning HAGS off, resetting the graphics driver (Win+Ctrl+Shift+B), re-plugging DP to force a handshake, deleting the monitor in Device Manager, repeating factory resets, switching between DP 1.4 and HDMI 2.1. The behavior stays unstable: something can make it feel perfect for a short window, then it degrades again.
At this point it doesn’t feel like a normal human perception / FPS placebo thing. It genuinely feels like the monitor/driver/Windows presentation path is switching into a different state (low latency vs buffered/queued or something like that), and only a mode change temporarily pushes it back into the “right” state. I'm thinking about bying MSI MPG 271QRX(same pannel as mine), and check it the issue also persist there. One guy left a post here where he had almost the same problem. If anyone has seen something similar on this monitor or on other 1440p/360 Hz OLEDs, I’d really appreciate any ideas.

maybe try old 144hz and rule out the monitor?
