[Various] ASUS debuts ROG SWIFT PG279Q 144hz IPS and G-SYNC - Page 170

Overdrive without overshoot is absolutely issue-free.

but the fact that it needs error correction to keep from overshooting, shows there's more going on than simple increased voltages, and that's where the frame interpolation comparison come in.....no it's NOT exactly frame interpolation, but I never said it was.

once you turn overdrive off, the monitor has a latency of G2G of 11ms. That's 90hz maximum, even though the monitor will still report it running at 144hz, which means it's a lie. Fact is, monitors can say they're running at refresh rates they're not actually physically running at.

What error correction? The error is when overshoot DOES happen. All overdrive does is apply voltage for a much higher luminance in order to greatly increase the speed with which a pixel performs a transition. Overshoot only happens when the voltage is not normalized in time.

Yeah, so? That's like saying sports cars are not fast because it's only the turbo doing all the work...
You need voltage either way to have a functioning LCD panel. The only difference is overdrive makes the voltage application much more dynamic.

What? I did not say a word about blur, I was talking about input lag, if it is over 6ms then it will be more than 1 frame of lag, which will make it effectively worse at 165hz compared to 1 frame of lag at 144hz.

eg. 2 frames of lag at 165hz is worse than 1 frame of lag at 144hz.

Also what is this madess about "if a monitor cannot run fast enough response times without overdrive, then it is not 144hz"

If the monitor can run fast enough response times with no overshoot, or not noticeable overshoot, why the hell does it matter if it is using overdrive?

Sometimes I think people say things out of sheer boredom.

If a monitor can only do the speeds with massive overshoot, then there is a problem, the only problem with overdrive, is overshoot, so if there is no overshoot, then that is the effective speed of the monitor.

Maybe someone should make a separate thread for "random ramblings about monitors in general"

I think he's actually under the impression that the monitor is "making up" frames in order to maintain 144 Hz. At least that's what i could gather from his post.

Delta E à 1,8 http://img1.lesnumeriques.com/test/11/11415/couleur--calibre.jpg

This is not good for an IPS considering Delta E of MG279Q is about 0,7, of course the MG279Q has its own problems, but for 900 euros monitor (PG279Q) it should have been perfect.
At least to me color accuracy is very important because I don't want this monitor only for gaming.

I must have misread your post, sorry.

As long as screen can finish pixel transitions in time of 1/refresh rate then you won't see blur - it doesn't matter at all how much time monitor electronics spent on processing image since all frames are delayed by same amount.

If you have TV with motion enhancing functions it can easily have 100+ms of input lag and somehow that still works as cleaner less blurry picture than standard mode (and if we followed logic from quoted post it would be 8Hz display then).


Not aimed at me, but it is an informative post. So, if the PG279Q use the same panel as the XB270HU, shouldn't it have the same response time and signal processing theoretically?

We can see that the XB270HU has lower signal processing than the PG278Q, but is it possible to tell the difference in real use? It would be interesting to know the differences if there are any.

What I've read suggests that the added video connectors may increase signal processing. The MG279Q doesn't have the same response times/lag as the XB270HU.

The HDMI port being there definitely has something to do with the signal processing time being higher, if the french review is anything to go by. This is gsync V2 which allows for that HDMI port to work with other devices because the gsync module actually replaces a typical monitor's scaler and is why earlier gsync monitors only had displayport. Now with V2 you get DP and HDMI, but HDMI won't be benefiting from gsync's capabilities.
