Yes, the downside is that you will get tearing without a syncing technology. V-Sync will always add input lag, though this can be reduced by using triple buffering and setting an in-game FPS cap to around 118. Also, Fast Sync is a new alternative that won't add lag, but I've read mixed results about it (the problems being stutters).

ULMB itself might add some amount of input lag, but I've never seen anyone complain about it.

Just got my XB271 set up, no dead or stuck pixels to report. March 2016 batch. However, there's some very questionable BLB, but im just not sure what's worth sending back. It's only really noticeable during movies, but it's definitely there, dead center at the bottom. Also, a ton of IPS glow in the bottom right corner, but that's just par for the course. Worth keeping or sending back?

Loosen the screw at middle bottom on the backside of the monitor, lower brightness to 25% or so or whatever you feel is good for you and give it a week of heavy use. If you're not at the PC i would just let the monitor run 24/7 anyway to give it a good burn in. The XB271HU is reported to have greatly reduced bleed with a bit of use, the glow on the other hand cannot really improve by much as its inherent.

I'm not sure what distance you took the photo from but going by how much glow is visible it wasn't three meters back. The camera also overexposes it so we see it worse in photos than what you're actually seeing. Also if you're running it at default brightness that's too high and unrealistic to take photos of demonstrating the bleed/glow.

I'll definitely give it another try with that middle screw loosened. Honestly the only thing that bothered me was the blb above the predator logo. The other ips glow really wasn't a problem. Thanks for the info, I'll post back in a couple of days with any changes.

Here is my XB271HU screen (Dec 2015 batch) BEFORE loosing the middle screw:



and AFTER:



it's the third monitor in a row after returned Asus PG279Q (had very bad IPS glow) and another Acer XB271HU (had 3 stuck pixels).

Glow in right bottom corner is still unacceptable for that price, but probably I will keep it because of no stuck pixels.
post #5996 of 7842
I think I'm going to overlook the small scratch and recessed button in light of the fact that I probably got quite lucky with the panel itself. No blb no dead pixels no noticeable ips glow.

However I've noticed that sometimes in games or after playing a game there is an odd vertical tear right in the center of the screen which is usually coupled with some sort of mirroring on the left edge of the screen. Anyone else experience this?

Over the weekend a new issue (for me) starting happening with my monitor. Has happened twice so far so I'm not yet very alarmed, but it is not a good sign. My monitor turned itself off and then back on causing my PC to stutter. I was ripping a CD at the time and it caused EAC program to completely freak out. Yesterday it happened again but nothing else happened. I checked event viewer in Windows and nothing happened, so it was the monitor both times.

Hopefully it isn't a monitor power supply failure waiting to happen. I bought the 2 year replacement plan from Microcenter but honestly if it does die, I am thinking of just requesting store credit rather than getting another POS Acer / Asus. I'll post here if my monitor does die. Bought it in April (Jan 2016 unit).

I have noticed that my newly connected XB271HU via DisplayPort (GTX 980 TI) sometimes affects other USB devices connected directly to the motherboard.

For example, when I'm locking my Windows 10 PC via Win+L keys and turning monitor off, USB mouse sometimes (not always) suddenly stops working (like being disconnected from USB).

Scrolling the wheel restores its functionality and Windows afterwards shows tray notification that there was a problem with USB device.

I have noticed this several times already after connecting XB271HU.

Moreover, 2 months ago I had another XB271HU (returned due to 3 stuck pixels) and while testing in Windows 7 it showed the same behavior with mouse disconnections.

Then I looked into DisplayPort specifications and noticed that it's able to transmit USB signals, so can affect USB devices indeed:

"In addition, the interface is capable of carrying bi-directional USB signals." https://en.wikipedia.org/wiki/DisplayPort

I'm not using XB271HU USB cable and not attaching any devices to the monitor. So, only DisplayPort itself can affect other USB devices in my case.

What a crappy technology...

Shardnax pointed out that if G-Sync & V-Sync are turned on in NVCP then your fps won't go beyond 144hz.... I'm yet to test this as I have always had V-Sync off and G-Sync on in NVCP with my frame rate locked in game at 144. Although as you point out, on occasion I noticed that my FPS will jump above 144 despite the lock. Is V-Sync in NVCP any better at locking than say an in game fps lock?

If you're playing a game that has an FPS limiter option, use that and set it to 142 or so. Then it doesn't matter whether or not V-Sync is set to On, because this FPS cap will ensure that the only thing active will be G-SYNC, and it will prevent FPS from going over what you set it to. G-SYNC adds far less lag than V-Sync which is why this is the best option.

If you're playing a game that does not have an FPS limiter, then it doesn't really matter if you have V-Sync enabled or if you have a global FPS cap instead. Both add lag, and either way most people won't detect the added lag of either.
