Acer XB270hu To blurry

[Phixsator]

So ive just purchased an Acer XB270HU, coming from an LG 29um57, hoping i could keep the good colors while removing the horrible blurring and i found out that i was wrong. Problem is whenever i look at the screen and im turning left or right semifast/fast in a game the screen blurs so much that my eyes are strained to the point where i can psychically feel it. Its not very pleasant and the monitor will be going back but i need a replacement.

I already tried the ROG swift like 7 months ago but the coating on that monitor is horrible not to mention the color/gamma shifting (whatever its called). I could perhaps live with the color shifting if it meant next to ZERO blur. Would also prefer g-sync if possible but main goal is to kill as much blur as possible. Any ideas? budget cannot be higher than the cost of the Acer XB270HU. Thanks in advance

Enable ULMB or swap it for a CRT.

ULMB i tried and it did amazingly for blur reduction. Problem however was the overshot.. it was so visible and annoying. It appeared in a dark greenish fasion like a ghost of the previous image tinted green. EWW.

This is because you can't adjust overdrive during ULMB for some extremely stupid reason.
This was a noted complaint when the first Asus VG248QE Gsync do it yourself module upgrades came out and you had to swap out the Asus electronics (losing Lightboost and Tracefree, etc) for the Gsync hardware. On ULMB monitors, you are stuck with what the factory gives you, so you have to hope it's good enough.

While the colors were better in ULMB mode with the module, there was significantly worse crosstalk at the bottom of the screen.
(This is because Lightboost used "Accelerated scanout" which is equivalent (I've tested it pixel for pixel) to the Benq blur reduction equivalent of the "VT 1500" trick.. They actually do the exact same thing, which is why the Benq monitors go "out of range" at VT 1503, but not at VT 1497-VT 1502 (this is what lightboost uses).

Lightboost mode used per line overdrive and was generally calibrated quite well in most cases. On some Asus monitors, you could enter the Service Menu and reduce the overdrive gain even more, which applied to Lightboost mode. (OD Gain was a gain, not the actual TraceFree value. This value was called "OD Strong/weak" on older Asus monitors.

On the Benq monitors, there are several methods for adjusting overdrive while strobing.

Also you need to remember you are using a IPS monitor, which will have slower pixel transition times than a TN.
Try 85 hz ULMB and compare it to 120hz.

is the ghosting less?
Use this test.

First thank you very much for the extensive reply and explaining a ton of stuff that i have to be honest about i know very little about. That said, the screen would overshot less at 85hz ULMB or not doesnt matter but problem was even more blurr would appear(logically). So the end results are that i have given up getting it to work as i wanted, as i got headaches after 10 minutes and severe eyestrain, so i have returned it to the shop pending a refund. Looking for something else and im pretty sure it will have to be TN based, sadly as i dont like the color/gamma shift. Got any recommendations? for the same or preferably less than the Acer xb270HU? Has to be 120hz minimum but the rest would be open for discussion.

Did you end up getting a different monitor? I have the next gen of the XB, the XB271HU... I'm not sure if it solves your problems with ULMB mode, but I didn't see any pixel overdrive ghosting. The problem is I think I saw a lot of strobe crosstalk, particularly at the bottom half of the screen. I'll test it again today and let you know.

If you are looking to cut costs, you might be interested in a monitor that doesn't have G-Sync, but still has strobing. I know BenQ has a few models. There's that VA panel also from a couple of years ago, the Eizo Foris FG2421 that has a strobed backlight. It got really good reviews, though people complained about QA problems. Also, VA panels tend to be even slower than the current gen of fast IPS, so there is probably some ghosting introduced. Though I think it mostly affects specific dark colors and is more subtle.
