Acer XB271HU- share your experience and show pics! - Page 355

post #3541 of 7663
Thread Starter 
Funny how on some monitor BLB is increasing over time (happened to one of my faulty PGs) and on other units BLB is vanishing over time, getting less visible (happened to my last faulty XB).

My retailer hired some specialist who will pre-check my next XB271HU for any defects, so they won't loose their and my time with sending me another defect unit just so I can send it back next day.

I highly appreciated my retailer decision. It is irritating for both me and them.

Well, we shall if that will finally deliver me a good unit.

I think it's the double-sided foam that is susceptible to temperature or/and orientation. Or just the steel panel backplate bends under the frame's pressure... it's hard to know for sure...

Which retailer is that?

Damn Benny you are still playing the lottery?

Code:
White level = 318.32 cd/m^2
Aprox. gamma = 2.39
Contrast ratio = 1365:1
19:42:17,959 White    Correlated Color Temperature = 6085K, DE 2K to locus = 12.2
19:42:17,959 White Correlated Daylight Temperature = 6083K, DE 2K to locus =  9.2
19:42:17,959 White        Visual Color Temperature = 5693K, DE 2K to locus = 11.8
19:42:17,959 White     Visual Daylight Temperature = 5813K, DE 2K to locus =  8.9



Doing first wave of calibration since it's been on for hours now. We'll see if it stays this way wink.gif

This is hilarious, it's degraded already!

I've performed some initial calibration for 120cd with 6500K and gamma 2.2 on my model, here are the results:

ColorMunki original software

2016-02-05_XB271HU_D65_120cd.zip 8k .zip file - 30 brightness, 55 contrast, 91/88/96 RGB



ColorMunki seems to be preferring gamma above all else.

DisplayCAL
XB271HU22016-02-0520-07D65002.2SXYZLUTMTX.zip 673k .zip file - 27 brightness, 55 contrast, 94/91/96 RGB



2016-02-05_gamma_2.2_perceptual_64.zip 646k .zip file - ReShade 3D LUT, Gamma 2.2 with perceptual intent

Edit: 55 contrast instead of 50, the OSD was wrong after MCCS.

Fantastic. So now we have to worry about this too. Is the bezel so thin that increased temperature from prolonged use causes some warping and / or more pressure on the panel?

Well... Since this is my last try at this monitor and the panel seems very good... I removed the case and the frame biggrin.gif

Edit: Which was the stupidest thing I could've done, it almost cost me the monitor. DO NOT DO THIS!

When the frame and case are removed the only thing holding the panel together with the electronics box (where the VESA mount is) is some black tape. It will not hold the monitor for long!

Fortunately I caught it in time, literally!



This is not for the feint of heart. It took about 30min with very simple tools: a screwdriver and a plastic opening tool (I used a bicycle tire tool). There's 12 screws in total and a lot of latches. If you don't have a VESA mount it won't work since the stand is useless without the case. I think I was found out since the power LED changed colour to orange so my warranty is probably out of the window wink.gif

It's quite interesting checking in on this thread after "winning the lottery" with an XB270HU last year. Back then it was common that people found that their BLB got better with time. But now with this model, people's are getting worse with time?

Some people had it get better over time for 271 as well. It's hard to tell why exactly, but I suspect it happens in relation to operating temperature. It can warp in a good or a bad way. I guess that's the price we have to pay for the slim bezel design.

That turned out to be just the service menu's Burn-In mode being active for some reason. After deactivating it all seems normal.

This monitor's versions are identical to my last one, HW and Panel Name are also the same, but after losing the case G-SYNC module's die temperature went down from 55°C to 46°C (same room temperature, same resolution/refresh rate).
