Asus VG279qm/VG259QM vs MSI MAG251RX. in depth comparison of the best IPS 240hz(i've tried them all,Amazon BAN incoming)

[js27]

Have you tried to disabling gsync? your problem might be it keeps turning on and off due to fps going above 240

Hi, I registered on the forums today to start a thread about the vg259qm AND rocket league. So I feel like this is the right thread to bring this up.

I have played Rocket League on a 24" 144hz 1080p TN panel for 2 years, Acer xf240h. Just got a tax refund and wanted a new, fancier panel. Ended up getting the VG259QM. The max fps in Rocket League is 250.

I am getting horrible tearing, or artifacts, not sure which, at 240hz/uncapped fps. I go into freeplay, start jerking the camera around, and i see black lines everywhere. I film in slo-mo on my phone, best i can do, and see that it's actually tearing, really fast. If i use G-SYNC ON/V-SYNC in NVCP ON/V-sync ingame OFF/cap 237 it looks awesome, of course. If i lower the fps cap it also diminshes the lower i go. But i would really like to play with uncapped fps. And it also worries me what will happen in the future when i play other games. This is an investment that i will be using for years to come.

My question really: How come this is does not happen on my old TN at 144hz/uncapped fps? Is this a Rocket League problem, or the monitor? As mentioned, most pros play with 240hz/uncapped. I dont notice anything while playing DOOM eternal for example. Maybe because I am focused on the crosshair? Am I just not an IPS-guy..?

I turn off any form of adaptive sync on my MSI MAG252rx but i don't really notice any tearing(sure, there's probably tearing but at 240hz on 250fps, i really have to look for it). But it doesnt' obstruct me from playing the smooth buttery gameplay the MSI provides(unlike my 60hz and 144 hz IPS monitors).

what GPU and CPu are you using and are they well synchronized? I'm using the rtx2070 gpu with a Ryzen 7 2700 cpu and i don't really notice much tearing leaving the FPS at 250 on a 240hz monitor.

but yes, the Meta is. TURNOFF g sync/free and maximize the 250hz framerate. You have the asus though, why aren't you using 280hz+elmb sync and modding the FPS from 250 to 300? U should consider taking advantage of your monitor's hardware capabilities.

I load into free play on DFH Stadium, and start jerking the camera stick up and down. The arch thing above the field looks horrible, and I see a bunch of dark lines from the stands, the hexagons on the ground/walls and so on. It's very obvious at 240hz/250fps. On my old 144hz/250fps it looks smooth.

Huh, synchronized..? I have an 8600K @ 4.8, RTX 2070 super, 16gb RAM@3200, games on SSD.

Got the monitor last evening, I am trying all the capabilities/functions of course. I just found it strange that I get this tearing at native. Since the only thing i changed was a higher refresh rate. FPS cap 237 looks ok. 280hz+ELMB looks better. G-sync 101 looks even better than that. Idk. 280hz just seems a bit excessive to me.

I just tried capping my fps to 154 on my 144hz monitor and got a similar result. Maybe it's a perfect storm with +10 fps on that map. Either way, think I'm keeping the monitor. Enjoying it.

either you are more perceptive than me or you have a defective product. You shouldn't be seeing any tearing(if there was, it should be subtle and not noticeable) on a 240hz monitor.

OR

you have a defective product. If you have time, could you screen shot those photos?

if however you can't see tearing on your 144hz TN monitor but you can with your 240hz monitor, then you might have a defective product where your monitor isn't refreshing correctly. It's VERY common fyi, the 1st generation IPS AU Optronics models have very poor quality control.

Chief could probably elaborite more on this but i'm fairly certain you have a defect. the Asus VG279qm/VG259qm is the fastest IPS monitor right now. I had it and i didn't notice any tearing at all(with or without g sync) at 250hz FPS on 240hz refresh

got my AW2521 the other day and it will be PACKED and ready to be returned(this is the quickest i've ever tested and returned a monitor).

Believe it or not, the new 25 inch alienware is the same AU optronics panel as the VG279qm and the MSI MAG251rx. But its overdrive implementation is horrible. Anything above the standard overdrive, there's overshoot. I measured at around 4.7-5.0ms g2g on my oscilloscpoe. on its standard overdrive. but it did clock in at .7 on some of its transitions on its "extreme" overdrive setting. it's fairly quick, but the overdrive implementation is awful. (then again, it's less subtle at 240hz).

I can confirm the new 25 inch AW panel isn't the same panel as its 27 inch predecessor 2720. it's using the same panel as the MSI and the 280hz asus models. except it's 8 bit(whereas the MSi is 10 bit)

You have to make sure Freesync is enabled and there'll be no overshoot on the Extreme overdrive setting. If it's off, then there'll be lots of overshoot like you experienced. Other users reported the same.

I do think I am highly perceptive, from experience with friends and family. I'm always the dude that notices a problem with the picture and people roll their eyes.

Oh man why'd you have to bring that up. Time? Corona. All I have is time. But screenshot of what photos..?
The best i can do is probably this, which is filming it with my phone in slo-mo: https://www.youtube.com/watch?v=JOx2EnchdxU
I have another video in real time but i really don't think you can see it once its on youtube. I can't. But in VLC I can.

I have several solutions for it. Right now im at 280+ELMB and fps unlocked. It only seems to happen in RL. I was more perplexed as to why it was happening in the first place. Love to learn.

Edit: Oh and I did the DDU in safe mode from Guru3d. Noticed there was an update for my BIOS available, might get that aswell.

For VSYNC OFF:
fps > Hz creates upwards-rolling tearline
fps < Hz creates downwards-rolling tearline
250 modulus 240 = 10 tearline rolls per second (and 10 stutters per second)

If you never used blur reduction in the past (144Hz without blur reduction), and you turned on ELMB only with your new 240Hz -- it's noted that motion blur reduction amplifies the visibility of stutter/tearing.

If you enable ELMB, you need to use fps=Hz -- or massive overkill framerate far beyond Hz -- to fix amplified visibility effects. Some can tolerate the cyclic stutters of fps-near-Hz, but not everyone can.

If you use ELMB-SYNC, a frame rate cap below Hz becomes important to eliminate tearng with ELMB-SYNC. The G-SYNC 101 recommendation is 3fps below Hz. If you're using ELMB-SYNC, it is necessary to use a frame rate cap BELOW Hz. That will eliminate tearing.

[Kimpalon]

Ok quick update. Having tested different combos pretty much all evening, it seems like 240hz/250fps is the ONLY one that produces the tearing that bothers me. 240-280hz. With or without ELMB. Unlocked fps. GSYNC. VSYNC. It ONLY happens at 240hz/250fps/VSYNC off. And only in Rocket league. So. A perfect storm for my setup it seems? I'll just stay away from that combo.

Chief. Do you think I have gotten a defective unit? I want to say the answer is 'No'.

Chief. Do you think I have gotten a defective unit? I want to say the answer is 'No'.

No. Video looks like what I expect for 240Hz/250fps combo.

It's more likely a situation of amplified visibility of harmonics. sometimes game-specific. 250 is pretty close to Hz, and pretty close to a multiple or divisor of a mouse pollrate (250Hz, 500Hz and 1000Hz). This can amplify beat-frequency behaviors such as rolling tearlines & non-random harmonic stuttering. So you've got 240-250-250(or 500 or 1000) situation for Hz-fps-pollrate.

fps-near-Hz sometimes creates more noticeable beat-frequency side effects such as more noticeable stutters/tearing, so would not be surprised if tearing/stutters are a bit more visible for 250fps when running on a 240Hz monitor than a 144 Hz monitor.

I would presume 240Hz/245fps will produce more noticeable tearing than 240Hz/250fps, but it is possible that some games (e.g. server tick rate interactions, mouse poll rate interactions) will have amplified fluidity harmonics at 250fps instead of any other frame rates, since 250fps makes the mouse feel unusually smooth.

Theoretically, with a 250Hz, 500Hz or 1000Hz mouse, the most ideal fluidity might occur with 250fps cap that is pollrate-divisor synchronized on a monitor capable of >250Hz VRR.

What happens to your motion fluidity feel when you cap at 250fps with VRR enabled (during 280Hz VRR), or VSYNC OFF (during Custom Resolution Utility created 250Hz mode)? Also test multiple mouse poll rates 250, 500 and 1000 -- the opportunity of attempting a 250=250=250 sync combo (fps=Hz=pollrate) is very interesting for the 280Hz montor and upcoming 360Hz monitor.

Overkill frame rate and overkill poll rate was classically used to smooth things out (e.g. 1000Hz mouse with 144Hz monitors) but with refresh rates and frame rates rapidly getting closer to poll rates, this can produce harmonic stuttering worse than what is fainly in this image -- mouse manufacturers need to release 2000 Hz mice soon.

Look up how to uncap rocket league FPS. It is a simple change in the dll file. I run at 400-500 fps with the VG279qm @ 280hz with elbm-->ON and sync-->OFF. looks great to me with no noticeable tearing. Correct me if im wrong but having your fps far exceed your refresh rate is similar to matching fps and refresh rate w/ ELMB but now with less input lag.

Kim is talking about rocket league which I am assuming he plays with a xbox or ps4 controller. Those devices have low polling rate, Xbox one controller is only 125hz.

That would also have harmonics with 250fps / 240Hz.

I'd like to see how 250fps-capped 280Hz VRR looks, or alternatively if using VSYNC OFF, what a custom-resolution 250Hz looks like. Not much experiments have been done yet, but with the new 280Hz monitors supporting 250Hz, there's an opportunity to eliminate one additional microstutter weak link.

That said, uncapping and going far beyond Hz (e.g. 400-500fps) creates enough overkill to eliminate microstuttering.
