Acer Predator XB271HU bmiprz 27" WQHD NVIDIA G-SYNC IPS Monitor,

I lowered my rating from 5 starts to 1 star.
The monitor is good. Moving from 60Hz to 144Hz is actually an amazing experience.
However, this monitor appears to have a known defect. In the middle of the screen there are times when a random vertical tear will appear. The tear is approximately 6 pixels wide. To accurately describe it, it seems as if someone removed a vertical strip 6 pixels wide from the middle of the screen and relocated it to the far right.
It is extremely noticeable, and the only way for me to fix it is to repeatedly power off and power back on the monitor. Many others have reported the issue, and so far the only permanent solution I read was to return the monitor to Acer for them to patch it.

Hopefully they sort out this issue in future revisions... but all for now, I wouldn't recommend it.

The monitor is great when it works: This monitor is known to have a bad panel that Acer Refuses to fix: Within 2 years of purchase date G-Sync will cease to function correctly, causing a flashing black screen. Disabling G-Sync fixes the issue, but like many others here, I didn't pay $400 to not use G-Sync:

Acer will not pay for you to ship the monitor to them, they will only pay to ship it back to you.

I gave this monitor a good review, but that was under the assumption it was a working product and didn't have any design flaws. And here I wanted to buy 2 more of these monitors for a 3 monitor setup. I'm so glad I didn't.

Great monitor if you get one that works. The one I received still has the Gsync bug from 2016 due to having falty/old firmware on the Gsync module. This is unacceptable as this was supposed to be fixed at least a year ago. Be aware when buying this monitor that the one you receive could have gsync issues.
