These monitors produce heat which will create condensation in cooler weather.

I will write on this issue to Acer again and also referred to your case, in writing I will give them a link to this forum thread. So I have a request to you, could you take a photos a few more pics showing your shape of this shadow artefact (more accurated/clearly) post them on the forum.

I would but it's early in the morning here and mine is nearly unnoticeable until the monitor warms up for several hours. Here is another pic I had on file

Hey guys! I just got this monitor and found this thread. 409 pages is a bit intimidating to read through.
Are there any must-follow tips to setup? Anything I should know?

i.e. is everyone overclocking to 165hz? or is it agreed upon that 120hz UMLB is better?

One last q: what is the Gsync range?

Has anyone experienced an issue where the monitor will no longer go to sleep?



When I lock my computer it normally turns off all my monitors after a minute and they go into their sleep or energy saver mode. They flash no signal briefly and then turn off.

Recently my XB270HU just goes blank instead. Does not flash "No Signal" and does not turn off. The Blue power light remains on and the screen remains lit up (the backlight) but there is obviously nothing showing.

I can manually power it off/on without an issue. It'll also resume picture as normal when I move the mouse or hit a key and wake the computer up.


The issue seems to have coincided with the Windows 10 Creators Update and the most recent nvidia drivers but I don't think it's either of those as it doesn't turn off when I have the monitor's display port cable unplugged either (though it will show the no signal OSD then).


EDIT: Further testing shows it isn't the monitor. False alarm! For some reason the center DP port on my 980 doesn't seem to tell the monitor to turn off anymore. Whatever monitor I have plugged into that port will not turn off.

My monitor has been turning itself on since I installed 378 drivers, 376 should be fine.
If I turn the monitor off, when my computer normally puts the monitor to sleep after 10minutes, it instead turns my xb270hu on by itself. Didn't even know that was possible.

I'm on Windows 10 Anniversary update, not on Creators. I'm using a 970.

Hi Guys. Anyone knows what's a good replacement stand with full movement ?

Attention XB270HU owners

You've been doing your monitor calibration all wrong!! If you haven't been adjusting contrast along side color temp settings, then your monitor is likely not showing its full potential. Even professional calibration software won't help you properly calibrate an XB270HU because it doesn't account for the dynamic relationship between color temp and contrast in this specific panel. That means those ICC profiles you've been downloading, well they're garbage!

My current calibration:

Contrast 93%
Gamma 2.2 in OSD, and ~2.2 in windows color calibration (use lagom LCD test site to help calibrate gamma, at the brightness level you intend to run at)
Brightness: 73%

Color Temp
R: 18
G: 17
B: 17

While monitors may differ, the rules of these settings are a guideline to get the best contrast ratios from black to white to colors that pop without going out of spec. Only minor tweaks to these settings should be necessary.

After calibrating my monitor like this, it was infinitely better in every way. The difference is night and day, almost like going from a TN to an HDR display. Most people don't move the contrast nor the color temp much at all, and none of the presets drastically alter the color temp this much, but these settings really are what makes this monitor shine.

Even when I did fiddle with contrast or color temp, I didn't do it in tandem or change it much and it always ended up looking off a bit or just OK. One thing not to do is raise or lower both equally. If you raise contrast by 10 points over 50, then you must lower color temp about 10 points too, and vice versa. But if you push both of them to the extreme opposites, they'll actually give you a much brighter vibrant image without washing out the darks or bright colors or making things overly saturated, and still display proper gamma. It'll feel like having a new monitor.

And if you want to take your newfound settings for a spin, here's a good video to do it with, really looks amazing on the XB270HU.

Looks decent, though that brightness is quite high. What brightness did you calibrate to?
