Blur Busters Forums

I'm OP, I ended up returning the PG248QP and bought zowie 540hz because I heard they could be operated at 500hz mode full RGB without DSC on. I wasn't able to make custom res again after switching gpus it was stuck to 360hz dsc off.

What's up with these random accounts making threads & commenting with no data?
DSC does not add any noteworthy input delay, despite how many people want to try and feel something.
What most here are "feeling" is better refresh rate compliance due to lower refresh rates, hence placeboing themselves that DSC is the culprit (heavily due to the thread of a similar title of a somewhat-known placebo-induced user). This is very noticable on the PG248QP, which is completely compliant at 360hz, but heavily missing the mark at 540hz.

You are just bringing up data while not actually owning the monitors and experiencing it for yourself. Refresh rate compliance has nothing to do with my cursor feeling heavy, it would just change the perceived motion blur due to the slow pixel transition. My no DSC 390hz Acer IPS panel was snappier than the asus 540hz despite the extremely bad refresh rate compliance. 540hz DSC on that asus monitor is comparable to playing in windowed mode with vsync on albeit at a lower degree. I found out that DSC isn't inherently bad but the input lag could stem from a bad DSC implementation on a monitor though. I've tested the 480hz ASUS OLED and it doesn't suffer from this issue.

I've experienced a similar thing. I don't understand how this could be if it doesn't show up in measurements (as long as they measure input lag in full-screen motion).

I've owned a PG279QM (IPS, 240hz) for years. Recently got a PG27AQN (IPS, 360hz) used.

After a few weeks with me not really understanding what was wrong I tried A/B:ing this yesterday - swapping monitor back and forth between DM rounds in CS2. Again - it's "feel" based now, not measurements - something I understand is a faux pas but I want to share my experiences.

No G-sync, ULMB or similar activated. FPS unlocked. FPS consistently way above the Refresh of either (450+). Playing at 2304x1440 stretched. Scaling on GPU.

The PG279QM feels snappier ("Mouse feel" as OP stated) at 240hz than the PG27AQN at 360hz. Utterly bewildering to me as all reviews, and specs, seem to state that the PG27AQN should be the faster monitor (TFT central measured refresh rate compliance and it looks really good at 360hz).

Hello so I'd like to share my dilemma with DSC and mouse input feeling. I have recently purchased the 540hz pg248qp and a RTX 3070TI because my 1080ti has no DSC capability so it capped the monitor to 500hz & 4:2:2 chroma subsampling; the picture quality was also hella ugly and I wanted to get a new gpu to rectify it. Now I have both GPUS, I get into a game with the 3070ti installed and instantly I can feel my cursor feel very heavy and my input delayed. Then I suspected it could be the DSC, I swap my old 1080ti back to the system and everything seems fine again, I swap both gpus again for 6 times already and I can notice the same input lag on this rtx card. I've also tried tweaked nvidia profiles on both cards and it's still the same. My system is also fully capable of running 540hz with high end parts. I'd like to know if anybody else experiences this issue.

I'd love to try esports pro mode on valorant but it just gives me black bars on the top and bottom of my screen regardless of any scaling option in nvidia control panel so I'm stuck with default. Any ideas? This monitor drives me fucking nuts lol.

Hey guys im not the smartest in this area but i play since i have memory, now i own a xl2586x i noticed in cs2 when i put 1280x960 in 540hz with dp, everything looks smoother but not much clarity? and when i put it like in 144hz or 240hz inmediatly i see the image not smooth but so crystal clear i dont know, in 360 its like a mid, smooth but are something a little bit more clear. Wanna say i owned the first 240 from zowie, owned a 360hz alienware and i sell it in 1 week, then come the 360hz zowie and was so much better than the 360hz alienware like much better but something jut feels off, i dont play like i was playing in the legendary xl2546 or the xl2546k, like if the monitor have a little bit of blur or something to make me miss, but with 540hz zowie everything changes for me but the DSC thing is driving me crazy, i tried everything i dont want the smoothest image, i just want something balance like SMOOTH but when you move your mouse fast you see clear everything, i noticed that the 240hz monitors where refined a lot to the point it becomes perfect but with the 360hz and 540hz panels seems like they are rushing releases to see who have bigger d..., the 360 can do 240 image perfect without strobbing and the same for the 540hz AUO panels, looks like can do some okay job in that 540 refresh rate but when you put in something lower like 360hz the AUO E-TN panels can do some amazing job, i buy also a OLED 240hz panel and compared to the legendary xl2546k, the oled beats everything except one thing, the strobbed image like come on i see a lot of people defending OLED, and i buy it being from a 3rd country just to prove if was that good, if you just want to click heads and no other things matter just go with the old reliable TN STROBBED, what do you think guys? and also it seems like from this forum another user post in the xl2586x seems like DSC is off when not need to use it, but when it need it i turn on for itselft its not like the asus one that you can disable the DSC Manually, maybe the zowie disable DSC when putting EDID 500HZ and settings the HZ to 360?.

I recently bought a 4K, 240 Hz QD-OLED monitor (Gigabyte FO32U2) and, although I'm pleased with its picture quality, the DSC technology is terrible. I never experienced any black screens on my old Gigabyte M27QP (1440p, 170 Hz) LCD monitor connected to my RTX4080S, but as soon as I connected the OLED monitor with DSC enabled, I started seeing them. The latest firmware update for my monitor has drastically reduced the frequency of black screens, so it's tolerable.

DSC however affects my aiming very noticeable and that's not tollerable. I have played quake 1 / 2 / 3 since 1999 and my aiming and reaction time is much better compared to average gamers. With DSC enabled, my aim is no longer accurate. I don't know if it's a lag issue or if the GPU drivers don't sync mouse movement correctly, but my precision takes a big hit with DSC enabled. Not even Vsync, or DLSS FG reduce my precision so much. Luckily my monitor has DSC switch and 1440p 240Hz is still very usable from up close on such big monitor (my monitor has dedicated 24'inch 1440p picture mode).

Edit : today, after a good night's sleep, I started testing everything again. Luckily, I found out why DSC affected my aim to such a noticeable degree. It was as if I were playing with motion interpolation on a TV, or when using crappy Lossless Scaling FG (I could feel the lack of precision during fast mouse movement). I changed the RGB range in my monitor's on-screen display (OSD) settings from 'manual' to 'Automatic', and the lag when aiming disappeared completely. It's a strange fix and I don't know why it works, but the difference is very noticeable.

To sum it up, 4K 240Hz with DSC works perfectly fine as long as RGB range in my monitor settings is set to automatic.

I managed to get a responsive experience with DSC and a 222 fps cap (using RTSS) instead of the usual 237 or 240 fps cap. The DSC lag is still there, but it's now so minimal that I can barely feel it, and it doesn't affect my aim. I can finally enjoy playing games with the DSC on like on my previous monitor!

I wonder, though, why playing with uncapped FPS and DSC leads to such noticeable input lag. Perhaps some VSync buffers are filling up, preventing DSC from working optimally. Without the RTSS cap, my vsynced frame rate is 240 fps or 225 fps if I use the ultra-low latency settings in the Nvidia drivers. Both 240 fps and 225 fps feel terrible, but capping the framerate with RTSS at 222 fps solves the input lag problem.
