It isn't their fault that Acer have no sample for UK reviewers. Cut them some slack.

Relax... Was just curious that's all. Normally I see them turn articles around pretty quickly, but I didn't know it was because Acer hadn't supplied samples (which doesn't make sense). They have had the X34 AND Z35 articles done for a while now, so no problem getting a sample of those monitors. Thought it would be similar turnaround for the XB1.

I'm more concerned about proper gamma settings which are harder to configure using just the Windows tool. My concern is if XB271 isn't capable of being calibrated properly. I don't understand how my cheap office monitors are at 2.2 gamma out of the box, yet my Windows-software calibrated XB271HU can't be set to 2.2 across all 3 categories on that Lagom site no matter what I do. It is just defect after defect after defect with these monitors, assuming I can't nail it using the Nvidia control panel instead. Granted I can't notice it all in my usage, but for the price this shouldn't be an issue.

Yeah, if you're curious, TFT Central has a forum and twitter feed, where the owner (Simon Baker) keeps people updated on the status of different reviews. He was expecting to receive his sample in December, but Acer sent him the wrong model (XB271HK, the 60Hz 4K display): It's been delayed I'm afraid for now. Not had the unit yet (was sent XB271HK instead)

He did say he expected stock in January, but he's also said that the review isn't currently in his work stack. Good job, Acer!mad.gif

But honestly, if you're mostly just wanting an ICC profile, I wouldn't worry about it much. For one, there seems to be a bit of variance from panel to panel, if you read people's settings in this thread... so you probably wouldn't get a great match for your particular panel anyway. Also, from my own testing (ColorMunki Display colorimeter), the panel is pretty well calibrated out of the box--other than the searing brightness! In my case, I got a reading of 6200K color temp, and a gamma average of 2.2. Most colors were acceptable error levels (~2 dE? I forget) except for red and green, which I think were a bit oversaturated, and of course their color mixes.

What also makes getting TFTCentral's color profile moot, is that the panel can definitely drift... as in, it may look more yellowish one month, then better the next month. Mine in particular went from 6200K temp initially, to almost 6400K after a month of use.

If I were you, I'd just eyeball the user color settings... if it looks too yellowish for you (seems to be the trend), then drop red a bit, and drop green a little more. For example: 98 red, 95 green, or 95 red, 90 green, etc. That will get you in the ballpark of 6500K and reduce the yellow tint pretty well.

The best solution would be to drop $1000 on a spectrophotometer like the i1 Pro (1 or 2) and do your own calibrations! But apart from that, you can get a consumer-grade colorimeter on the cheap, for $120-160. As long as you have a good correction file for the particular panel's backlight, you can get pretty accurate calibrations. I bought my ColorMunki for my Dell U3011 to help correct the wide gamut, and I've been using it ever since... love the thing!

Oh, did you use the Windows calibration thing to help fix the gamma? I have no idea how well that works, I remember trying it out a long time ago but haven't touched it since I bought a colorimeter. If it makes you feel any better, the default gamma might not be that bad. In my case without any calibration (other than fixing RGB levels), the gamma averaged 2.2 and hovered around that value through the 0-100% luminance, but at the 10% end it was more like 1.9, and at the 100% end it was closer to 2.4 I think. I can see a difference before/after calibration, but it's not a night and day difference. It's definitely not so bad as to cause clipping/crushing at either end, as you would be able to see in the contrast page.

If you want, I can upload a new ICC profile from my monitor when I get home... I'm currently running mine at RGB 99-95-100 I think? And 25 brightness. The ICC profile in theory should get your display to hit 2.2 gamma on that screen, if it's a good calibration for your specific panel.

Yes I tried using the Windows 10 calibration tool. I plan on heading to Microcenter after work and picking up a Colormunki + downloading DisplaycalGUI. Currently my RGB is set to 95-91-97 (maybe I adjusted B to 100, can't remember). It was pretty warm out of the box. Brightness I have at 30. Even if I don't notice much of a difference I'd still like to try using a calibration device just for kicks, never tried before.

Cool, that's where I bought my ColorMunki also. Are you going to get the "Smile" or the "Display" version? I got the Display, since it's basically a slower version of one of the best colorimeters available, the i1 Display Pro (i1d3), but apparently the Smile is similar to the i1d2 so probably not too bad. Both are supported in DisplayCAL.

You'll have to post your calibration results after you get it all figured out and running!

Edit: If you get the Display version, try to get MC to price match to Amazon... they don't officially but if the price is reasonable they usually will do it. Right now MC is selling for $200 but Amazon is $164. I think I got mine on sale at MC for $169 at the time, so they probably will match.

When I sent back my 4th one I did the same and also spoke with someone over the phone to document everything. Lastly I wrote a polite email in response to their "how can we improve" email, explaining everything again, and they responded with appreciation for the detailed feedback and for me "making sure my buying activity complies with their policies" whatever that means...I assume not just returning due to buyers remorse. All is fine with my account. I haven't since ordered another XB271 from Amazon, so no idea if returning another one would lead to account closure.

I would email them back and explain what you've been going through with this crap QC by Acer. If you return your next one definitely document everything that's wrong with it. I've noticed that Amazon isn't even selling the XB271 at all for the last couple of days, not even an "under investigation" message like before and no "more on the way" notice either. I'm sure they have gotten many returns of this monitor. The XB270HU is under review again too.

I did the same thing, i always took pictures and showed them what was wrong with the monitor. A part from monitors, i didn't return anything else. This is weird. I didn't like the way amazon communicated with me on that email. I understand that it is not their fault but it is also not my fault if items are defective.

I am relaxed. I was simply stating a fact. As a fellow UK reviewer who shares the same contacts as Simon I'm fully aware that certain things are beyond his/our control. And the lack of XB271HU sample availability is one of them.

Hey,
I forgot to ask.
On Xb270hu I could change 144 / 120 Hz on DP. On XB271HU i can only use 120 Hz on DP oO. My card is 770 Gtx.

Whats going on?
