Acer XB271HU- share your experience and show pics! - Page 350

post #3491 of 7725
So I installed the newer ColorMunki software and used it to calibrate rather than DisplayCAL. I am impressed. Anyone know how I can view the results of the calibration? If I open up DisplayCAL (which does not re-load my prior calibration made by DisplayCAL) and load the generic "office D65 and 2.2" setting and then run report on calibrated display, is the report that gets generated accurate or is it not based on the actual calibration settings that ColorMunki app used? I did run the report, contrast ratio is lower than I want at 932 and white point is about 6460. Black level .12. But color-wise and gamma-wise it looks much better to my naked eyes than the calibration I got from using ColorMunki hardware + DisplayCAL calibration.

I can't upload my settings because I didn't touch a thing on the monitor OSD, I let the ColorMunki software take care of everything. If there is a way to share I'm happy to do it.

Got my XB271HU in today. Looks fantastic, very minimal backlight bleed. October 2015 production from NCIX. Gotta love 165hz with GSYNC. Coming from 1440P 60hz PB278Q monitor.

I'm not totally sure how that report works. I think it takes readings and determines if the current profile is still a good match for the display. Maybe someone else here knows more about how it works? I downloaded a separate app called HCFR, it's great for taking measurements and generating a report. If interested, I can PM you some pointers for using it.

I thought that if you let CM automatically adjust your screen settings, when you go into the menus you would see what the end results were (ex. brightness, contrast, user color, etc). Personally, I would make the adjustments manually using that interactive calibration in DisplayCAL first, and skip the auto thing in CM (can be disabled in preferences). That way you can tweak it yourself and see exactly how it affects the color and brightness.

I'm not sure if you noticed the disclaimer or already knew this, but when calibrating your display, make sure the display has been on for at least 30 min so it warms up first... an hour would be even better.

Like I mentioned earlier, your monitor is going to have the highest possible contrast when running at the native colortemp and without any corrections. If you want to see what your max contrast would be for the display, try this: start a calibration in DisplayCAL, and for the interactive part, once the white square is displayed, place the sensor over a black picture on the screen (ex: dead pixel text). That will give you the black level, and the Initial reading should be your white level.

I wrote down a list of my black / white levels based on my brightness setting: Warning: Spoiler! (Click to show)
Brightness: White / Black Level (using warm setting)
  • 0: 57.241 / 0.048 = 1193 : 1
  • 5: 72.852 / 0.061 = 1194 : 1
  • 10: 88.753 / 0.075 = 1183 : 1
  • 15: 104.304 / 0.087 = 1199 : 1
  • 20: 119.623 / 0.100 = 1196 : 1
  • 25: 134.740 / 0.111 = 1214 : 1

You may notice that the contrast ratio floats right around 1200:1 throughout those settings... nice and consistent!

If I adjust the RGB to reduce the green tint (100-96-100), I get a 6350K color temp and these white/black levels:
24: 122.199 / 0.108 = 1131 : 1

If I adjust the RGB to 6500K (99-95-100) I get these levels:
24: 119.588 / 0.108 = 1107 : 1

Thanks for the info again. I could not see any of the settings within the monitor OSD when running with the ColorMunki calibration. Re-calibrating now with DisplayCAL. I set it to use "as measured" white rather than setting it to 120cd/m2. I could not adjust my monitor to less than 27 brightness and still get balanced colors and white within the interactive calibration (goal set to 6500K). With 27 brightness and RGB set to 96-92-100 I get white level of 120.94 and black of .11. So that would be contrast ratio 1099.45 : 1 which is fine by me. Hopefully the end result will be good. I'll post the report later when it is done.

Here's the report after calibration. Looks very good to me.

Heya

My 2th Acer is here. I can't remember, standard settings on WARM had a Yellow tint?

My Acer looks like this w/o calibrate http://www.overclock.net/t/1581181/acer-xb271hu-share-your-experience-and-show-pics/530

Edit: Omg again Dead Pixel Left bottom ...

The "warm" setting within the monitor's OSD is exactly that- a warmer looking white. I agree it is a bit too warm for my taste. Usually they can be calibrated but not always, some monitors can just be wonky. A properly calibrated screen (set to 6500K) will appear warmer than typical screens that we're used to that have a cooler / blue hue.

Try playing around with the OSD settings and change the color profile from warm to user. Adjust the red, green, blue to your liking or within the Windows calibration program. A higher blue and lower red + green will result in a cooler white. Every monitor is different and someone else's settings may not look good on your screen. For my monitor my best settings so far within the OSD have been to lower brightness to 27 and set R-G-B to 96-92-100. I used DisplayCAL and a ColorMunki for calibration target of 6500K and 2.2 gamma. But you can try the OSD color and brightness adjustments and also adjust your gamma within the windows calibration tool and get pretty close to ideal.

That is of course, if you decide to keep the monitor despite the dead pixel...that sucks. I feel your pain. Went through 7 monitors myself.

I think all the people getting these emails deserve it. There are tons of people who won't be picky about BLB yet you guys opening up monitors and sending back without penalty is bad for Amazon considering it is not their fault. If you have an issue one time then returning once is fine but purposefully playing panel lottery with a reseller is bad form considering reseller offers full refunds without penalty.

If you don't like a product take it with the manufacturer and resolve it with them or vote with wallet and stop ordering.

So what message does this send to the manufacturer (i.e Acer) exactly? That it's OK to produce monitors with BLB because consumers won't be able to keep returning them without incurring financial penalty so they should just keep it (or not buy in the first place... yeah, they really don't want that)!? The only reason they keep producing this junk is precisely because tons of people aren't picky as you say, but in reality if everyone was, they just wouldn't sell any and would be forced to produce a better quality product. It's pretty simple.

Oh, and have you seen Amazon's profits lately? They aren't hurting by accepting returns on this monitor... no matter how many there have been. They will take this up with the manufacturer anyway, and if you think Acer have more clout than Amazon, keep dreaming... Amazon aren't losing a penny over this, the ultimate cost for returns will hit Acer, but as I say, when enough people keep accepting their shoddy products, they can continue to absorb those losses. Instead of having a go at consumers who are TOTALLY WITHIN THEIR RIGHTS to demand a quality monitor, why don't you direct your attention to the monitor manufacturers instead and demand they improve the quality of their product.

That's a very broad brush, guys. I went through 2 Asus PG279Qs, the 1st had a dark top half of the screen that was way off compared to bottom half, that could not be fixed with adjustment. It also had bad backlight bleed that was visible in every day normal usage, not just solid black screen. The 2nd one had a bright white hotspot about 5x5 pixels square shape in the middle of the screen. These are flaws that are not tolerable in an $800 monitor.

I went through 7 Acer XB271HU's, yes. I returned not a single one solely due to poor uniformity or normal backlight bleed. The first 6 monitors had a combination of dead pixels, stuck bright pixels, dust under the screen, an eyelash under the screen. One of them was previously opened and re-packaged by Acer, box torn, packaging not sealed, which I posted about earlier and Amazon agreed with me on, spoke with them over email and phone about it.

Who are you people (in general, not you two specifically) to tell me that I should keep a monitor with these defects, which costs $800, just to appease Amazon / NewEgg? I have said many times in this thread and the PG279Q thread that some backlight bleed is not a deal breaker for me. Dead pixels, stuck pixels, hairs, hot spots, heavy BLB are all valid defects that we shouldn't tolerate.

My current XB271HU has some backlight bleed at the bottom center and bottom right. But it is not at all noticeable in regular usage, gaming, or even when displaying a black screen in a normal viewing environment. Not at all similar to the Asus that I tried. Uniformity is close to perfect and no pixel defects. Which is all I ask for. I don't expect perfection.
