So this arrived around an hour or so ago.

First impressions are it looks and feels great. It feels a little more wobbly than my AD27QD, but nothing that would annoy me or become an issue.

Panel booted up fine.

I have noticed what looks like a group of dead pixels, or a lump of dirt? Which causes a small dark spot/blemish, sort of right centre of the monitor (urgh)

sRGB mode
Looks great, although the contrast feels a bit meh? (980:1) This might be me not testing correctly in Displycal though, although I’m pretty sure I am doing it correctly!

sRGB Colourspace
Leaving the monitor at default and changing the colour space to sRGB works too, the temperature here goes warm (5700k-ish), but, you still have access to the RGB controls, so this can be managed, managed to get this back to 6404k.

Just running through Displycal now to calibrate whilst it’s in the sRGB Colourspace, I want to see what the contrast ratio shows after a full cal.

Undecided on what to do with the monitor with the blemish/dust thing. Might be a case of sending it back to Amazon and having to order another, not sure they do door swaps?

Will fill in the gaps above with the relevant details when displayCal has finished

Thanks for sharing your initial impressions and findings. I often find the dedicated ‘sRGB Cal Mode’ (or similar) preset is just an oddly restricted and sometimes worse calibrated version of just setting the colour space to ‘sRGB’. Will be interesting to see how the contrast ends up with that setting.

The blemish or dust sounds annoying, especially given it’s towards the central region. Unfortunately you would usually have to send it back rather than them sending out a new unit and doing a swap. But probably worth the inconvenience anyway given those imperfections.

Okay. So I don’t have the exact measurements to hand, was in a rush ordering a replacement, this one is going back!

sRGB cal mode, everything was under 2.0, in fact, I think everything was under 1.5? Temperature was a little in the warm side at around 6100k. Contrast was in the high 9xx:1

sRGB Colourspace, with tweaked temperature using RGB, highest was 3.6, which was a red (23/24 in displayCal?) everything else was less than 1.5. colour temp was 6408k. Contrast ratio was still high 9xx:1

Running a calibration whilst in the sRGB Colourspace, got me to 6408k, and everything was less than 2. Contrast ratio was still high 9xx:1

Maybe a duff panel?

I did also notice when I flicked the refresh rate to 180hz, the screen would randomly go black, like it was switching on and off? 165hz and below all seemed fine.

I have kept the results in a folder so I will post them tomorrow. Along with the results of the new panel.

Ideally I don’t want to be using displayCal, I’d like to just toggle to sRGB and away I go.

Original Unit

sRGB Mode
White Point: 6184k
Measured vs. assumed target whitepoint ΔE*00: 0.91
Average ΔE*00: 1.17
Maximum ΔE*00: 1.9

sRGB Colourspace
White Point: 5718k
Measured vs. assumed target whitepoint ΔE*00: 3.21
Average ΔE*00: 1.13
Maximum ΔE*00: 2.08

sRGB Colourspace – Tweaked RGB
White Point: 6440k
Measured vs. assumed target whitepoint ΔE*00: 0.43
Average ΔE*00: 0.91
Maximum ΔE*00: 3.64

New unit arrived last night, booted it up this morning. No signs of any dirt/dead pixels etc. Feels a bit sturdier than the original one too.

I’ll leave it running for an hour or so, then look at dropping displaycal on to do a verification and see what it’s showing

Update: At first glance, this unit probably looks worse in terms of accuracy out of the box!

Urgh. Will update shortly

Second Unit

sRGB Mode
White Point: 6188k
Measured vs. assumed target whitepoint ΔE*00: 3.65
Average ΔE*00: 1.04
Maximum ΔE*00: 3.36
Contrast Ratio: 976:1

sRGB Colourspace
White Point: 5580k
Measured vs. assumed target whitepoint ΔE*00: 3.41
Average ΔE*00: 1.28
Maximum ΔE*00: 3.45
Contrast Ratio: 856.8:1

sRGB Colourspace – Tweaked RGB
White Point: 6675k
Measured vs. assumed target whitepoint ΔE*00: 5.57
Average ΔE*00: 0.89
Maximum ΔE*00: 3.54
Contrast Ratio: 899.6:1

Full Calibration (sRGB Colourspace using LCD PFS Phosphor WLED family Correction)
White Point: 6562k
Measured vs. assumed target whitepoint ΔE*00: 0.42
Average ΔE*00: 0.14
Maximum ΔE*00: 0.7
Contrast Ratio: 907.2:1
sRGB Volume – 98%
sRGB Coverage – 96.5%

All in all, I think it’s pretty disappointing? In Comparison to my sRGB Clamped AD27QD with Displaycal on top which gives the following:

AD27QD (sRGB Clamp tool and DisplayCal)
White Point: 6497k
Measured vs. assumed target whitepoint ΔE*00: 0.35
Average ΔE*00: 0.22
Maximum ΔE*00: 0.8
Contrast Ratio: 1153:1
sRGB Volume – 99.6%
sRGB Coverage – 103.2%

I think it’s safe to say, that it’s probably going back!

[PCM2]

Yeah, that’s not great. Understandably disappointing.

[jbennett360]

Yeah, it is when you think the Gigabyte is a 5 year old display, with a panel that’s probably a little older too?

I would have thought by now that all of this would be resolved or at least on par with the Gigabyte, but it seems like it’s not, or, it’s still such a massive lottery.

Another thing to note too is that I wasn’t keen on the matte coating on the XG27ACS, definitely a lot stronger with a bit more ‘grain’ than the Gigabyte model

Please can you tell me the exact BOE panel this monitor uses ?
Is it BOE MV270QHM-NF2 ?
TY 👍
