Looking for clarification on if AOC AG251FG supports 1440p

Post by CRTguy » 05 Dec 2017, 09:07

So when I look for the stats of the AOC AG251FG in stores or even on the AOC official page, the monitor appears to be a 24.5 inch 1920 by 1080 res TN panel at 240hz.

However, I found these three review articles that claim the monitor can do 1440p:

http://www.guru3d.com/news-story/aoc-la ... nitor.html

http://www.pcgamer.com/aocs-agon-ag251f ... -or-240hz/

Is this just a case of all of these reviews / previews spreading misinformation? If anyone can help clarify the history of whatever happened here, that would be great. I saw that RealNC posted a comment on the guru3d.com review site (at bottom of page) back in May 2017, and he also seemed interested in knowing about the resolution capabilities.

Thanks.

There never was answer for this, but I think the most logical conclusion is that the monitor has a 1440p panel. So I would suspect that if you lower the refresh rate (probably 170-ish Hz?) you can use 1440p, but for 240Hz you can only run 1080p.

If that is indeed true, then this monitor will be pretty crappy at 240Hz due to scaling.

Eh.. I can't believe that a manufacturer would market a monitor as 1080p when it is actually 1440p. I suspect there is more to this story, and my guess is that AOC announced the AG251FG as 1440p before release, but on actual release they just went with the stock 1080p 240hz panel that everyone else is using.

The AG251FZ is apparently the exact same panel as the AG251FG, and yet the AG251FZ was never advertised as 1440p. This makes me think those two monitors are using the exact same 1080p 240hz panel since one is the G-Sync model (AG251FG) and one is the Freesync (AG251FZ).

I'd love for this monitor to be a secret mystery panel that supports 1440p, but that just seems so unlikely. Maybe we'll get lucky and someone who knows more info will see this post.

It's a 1080p panel running at 240Hz.

Although the AG251FG and AG241FZ use the same panel, the overdrive on the AG251FG is MUCH better -- motion looks clearer. This is due to NVIDIA's better overdrive calibration work -- this is part of the G-SYNC premium even in non-G-SYNC mode.

From TFTCentral's review of the PG258Q:
(They use the BlurBusters-invented pursuit camera tests).

Both 240Hz, same panel, but much better overdrive in G-SYNC capable 240Hz panels -- even if you do not use G-SYNC.

I have determined the AGON AF251FG has a pursuit appearance similar to the ASUS ROG PG258Q and ACER Predator XG252Q. The overdrive is extremely similar in all 240Hz G-SYNC monitor, and from what I know, NVIDIA's G-SYNC help for manufacturers -- includes overdrive calibration services and currently NVIDIA has the best 240Hz overdrive algorithms at the moment (even with G-SYNC turned off). It's part of the G-SYNC premium (sometimes as little as ~$50 during sales) which pays for a lot more than just G-SYNC.

Alas, the AF251FG (G-SYNC version of AOC 240Hz) is more easily purchased in Europe than USA.

Nah. It seems to have been a mistake by AOC. They removed the "2560x1440" from the site. So it's safe to assume that this is not a 1440p panel.
