I'd wager that's because CS:GO is the only game you've tried in which you can maintain 120 FPS. If one can maintain 120 FPS with ULMB @ 120 Hz then it's simply the best option especially with Fast Sync (although I've read this needs improvements). ULMB simply removes almost all perceivable motion blur with the only downside in this case being brightness (but it still gets bright enough for most).

With that being said there are some exceptions. Penumbra (both games and the expansion) look terrible with ULMB no matter what. Tons of odd ghosting.

Another thing i noticed, lowering brightness to 25-35 really gets rid of a lot of blb and glow. Default brightness of 50 or 60 is just too much, in my opinion. Also, since you are calibrated, I will suggest to get a backlight it to further enhance your color especially the dark ones. Also a 6500 backlight behind the monitor hides even more blb and ips glow. Here is what I am using

Cheers
Which one did you buy? cooler or warmer?
post #5485 of 7841
At first i bought the cool one. With my Tn panel it looked fine. However, with the ips panel, the cool white background made my screen feel a bit yellowish. So next, i bought the cool and warm combo, which has switch for both cool and warm white. I noticed, the cool color of the combo is actually 6500k while the cool only one has a blueish tint to it (6800k). Since I calibrated my panel to 6500k, i prefer the color of the combo. Hope this helps.

Hello guys,

After a long research period, i finally pulled the plug on this monitor. My old monitor was a 10 year old 21'' LG TN and after reading all the comments about how IPS is the real deal, i was expecting an incredible step up in image quality. Then i get this:



On the left is my old monitor. Am i hallucinating or my xb271hu's whites (and other colors) are REALLY off?

This is with standart preset colour temp, 80 brightness, 50 contrast


I also tried various icc profiles, nothing seems to do it right. This is also a photo with the following calibration mentioned here Warning: Spoiler! (Click to show)

The tape on the outside of the box was the original Acer tape and had not been taped over. Also, the box came in pristine condition with no signs of wear unlike the PG279Q I received a few weeks ago.

I have the most minuscule black light bleed in the bottom left corner. The other three corners show no BLB what-so-ever and it exhibits basically zero IPS glow across the entire screen. I see zero dead pixels, zero dust specs/spots and uniformity looks nearly perfect to my naked eyes.

This one is a keeper. thumb.gif

Out of the box colors were not as close to sRGB as I thought they would be, but were decent.

CALIBRATION:

XB271HU Menu Settings were set to the below to achieve the best desired starting point and as close to 6500K as possible before calibration:

The Standard Profile was used along with these settings.

  • Brightness: 28
  • Contrast: 50
  • Gamma: 2.2
  • Color Temp: User Mode, (R Gain 99) (G Gain 93) (B Gain 97)
  • 6-axis color was left at default settings and was not changed.


I calibrated and profiled the display using my X-rite colormunki display paired with the Argyll + Displaycal GUI combo. It acheived a white point of 6485K near perfect to the desired 6500K. A black depth of .010 cd/m2 which is outstanding, a contrast ratio of 1143:1 which is above the rated 1000:1 contrast ratio listed by Acer. A Delta E Average of 0.19 and a Delta E Maximum of 0.75!!!

  • Achieved White Point after calibration: 6485K
  • Black Depth: .010 cd/m2
  • Contrast Ratio: 1143:1
  • Delta E Average: 0.19
  • Delta E Maximum: 0.75





These results are simply amazing and the display looks gorgeous after calibration.

I will post the calibrated .icc profile below that was made for anyone that would like to use it on their XB271HU.

Cheers thumb.gif

Mine is the same, most of the settings I've tried from this thread give mine a red tint. XB271hu is on the right, Dell U2312HM on the left.

@ Chyral,

Congrats on your new purchase. In order to get a decent color temp, you need to set your rgb individually by urself. My panel is a little bit on the red side as well, so I set mine to R 97, G 98 and B 100. Also, if you really want to get the best color possible, you need to invest in a calibrator like Spyder5 pro or Colormunki Display. Those have settings there that will get your screen to as close to as 6500k possible. GIve that a shot, and if not satisfied you can always return the monitor for a newer one, but the next one could be worse or better, its a lottery.

If you dont like your tint of the panel, you can always drop red level and green level to make it more blue. However, if you have to turn it too low, like below 90, the I would recommend returning it gor a new one. Also, whats your manufactured date?
post #5490 of 7841
Thanks for the fast reply, i guess i'll look into buying one of those calibrators..
