05/22/2020 UPDATE. The IPS 240hz monitor tier list.(I've measured/tried the all) and my honest explanation why.

[fowteen]

Unfortinately, against the fastest TN like the omen x25fs or the benqs or the xv272 nitros gave me fits because the differences in g2g averages will help them. Especially when moving the camera. And yes, the fastest TN input lag is just as good as the acer nitro/predator ips 240hz panels

Have you used the omen 25f? The ips monitors you recommend are always out of stock/not available where I live however the omen 25f is and at a pretty good price. I heard it had really low input lag so was wondering if you have any experience with this monitor or would recommend it to someone who is purely looking for performance?

Why would you not want to return monitors with dead pixels until you get a monitor that has no defects? Is it that you are eager to use a new monitor or some other reason?

It’s bcs idk how many more times I’m going to bother to carry this 8kg package for a post office that is a kilometre away.

@ fowteen

Purely performance wise the X 25f will be a good choice especially when you get it for a good price.
I tried two of them before and both suffered from "inversion artifacts" vertical lines when moving in game but you could be lucky to find one without that problem, for me it was really annoying.

I would opt for that walk, that dead pixel doesn't go away and can get really annoying once you know it's there.
But maybe you don't mind it's a personal thing

Erm people buy high refresh monitors at 240hz because they play competitive titles like csgo, overwatch. Why will u buy a 240hz monitor and play AAA titles to begin with? AAA titles u should get a 1440p 165hz ips monitor.

In my case (maybe he wants the same, maybe ), as RLCScontender reported that the MSI MAG251rx set at 120Hz can show 12bit colour i'm wondering if i can get best of two worlds by having it at 120Hz+12bits on some (most ) games and at 240Hz+8bits on faster ones (i mean, if lucky to find the "good" panel).
Still wondering if that would have any advantage or more futureproof over a 144Hz monitor, or should choose a 144Hz one and forget about these "tricks".

Yeah I contacted the company yesterday by email and I received the return number this morning. Took me some hours to think about though.

Have you got any images or examples you could show of these vertical lines? I have heard and seen what coronas / inverse ghosting looks like but have never heard/seen vertical line artifacts.

No I haven't a picture, to give an idea it looks a bit like this https://forums.overclockers.co.uk/threa ... .18503082/ but much more faint and only visible when you move in game horizontal ( a-d on your keyboard) or when you make 360 turns, it is more common with TN panels with a fast pixel response time but also a panel lottery issue. Like I said you can give it a try (It's not on all and you could be lucky) make sure you buy the monitor from a shop with a good return policy. It's one of the reasons why I choose for a IPS panel.

After intensive VRR and strobing testings on the VG259QM I want to point out a thing that hasn't been discussed on this thread:

- Standard ELMB with no VRR on this monitor has a noticeable improvement in motion clarity compared to ELMB-Sync, the devil's horn is more noticeable than I previously tested causing image doubling.

At first I didn't really understand why a5hun criticized ELMB-Sync's implementation, I think Freesync failed to correctly enable giving me the standard ELMB result which was too flawless to be true, there were no devil's horn arctifacts.
Iirc I changed the 48-240hz VRR range to 48-280hz with CRU after my frog pursuit testings, so it forced standard ELMB at 280hz the first time I tested.

a5hun is right, don't buy this monitor for the ELMB-Sync feature.

So what I use now for competitive gaming is 280hz refresh rate + ELMB (with VRR disabled), at 280hz I don't really notice tearing even in the 220-280fps range.
The strobe duration last 1ms compared to ELMB-Sync's 2ms, which is surprisingly long enough to remove crosstalk and idk if it's placebo but I feel like processing lag is reduced compared to ELMB-Sync (there's no need to sync strobe with framerate).

This is a message to VG279QM/VG259QM owners who are currently using ELMB-Sync at either 240 or 280hz: Disable Adaptive Sync and try to ELMB with no Freesync/Gsync.

Disable Adaptive Sync and try to ELMB with no Freesync/Gsync.

I only have a setting in the OSD called ELMB-Sync, no ELMB by itself. Same with Freesync disabled, so is the setting ELMB-Sync but Freesync off, or is there a separate setting for ELMB?
