Did I possibly get a bad screen? I see report deltas of 0.5 and 0.7 in youtube reviews while mine is at 1.03...

Should I send it back?

Based on the factory pre-cal report? No.

Anything below 3 dE is already considered imperceptible. 1.03 dE average is still excellent, and these numbers will vary from panel to panel, even on the same model. That, and most monitors don't even include a factory calibration report, so you're already getting something most models don't offer.

Going through multiple monitors to get a "better" factory calibration chart is futile, especially if your unit doesn't have any other standout issues.

Also, it's just a report, and said report only applies to "SDR mode / Default Mode." You'd have to use your own meter to verify those results, which would entirely depend on your current monitor picture preset, brightness/contrast level, color temp setting, etc.

E.g. if you're deviating from the default mode in any respect, that report will no longer fully apply anyway.

So you're saying Asus' calibration average delta isn't indicative of the panels actual color precision?

However, upon further testing, it definitely is frameskipping. The jitters don’t show at the usual motion speeds, but coarse stroboscopics show at fast speeds (for 2000Hz pollrate and up).

Although I do not recommend this mode on the PG259QN, it is rather interesting to see a partially-working 433Hz overclock. The 366Hz overclock, however works, although an unnoticeable difference due to the geometric upgrades required for refresh rates. 6Hz upgrade is just about visible at 60Hz (10%) but invisible at 360Hz (2%)

I'm saying the report is only indicative of the panel's color precision in the reported mode.

If you deviate from OOTB settings for the calibrated presets (apparently the "sRGB" and "Default" modes), that report will no longer fully apply, as you may have then adjusted the panels color temp setting, peak brightness (etc), the former of which will throw off the grayscale, which, in turn, will throw everything else off to a degree.

If you want to ensure a "proper" calibration (which is relative to what standard you're trying to achieve), at the very least, you'd need a i1Display Pro colorimeter (~$250) and DisplayCAL software (free), and even then, while it's better than your typical TN where color reproduction and contrast ratio is concerned, you're not going to reach reference studio display quality on a consumer IPS display with a ~1200:1 contrast ratio (which, don't get me wrong, is still great for an IPS panel type; my main is a 1200:1 IPS as well).

It also depends on if you truly desire a fully "calibrated" image. For instance, this is an sRGB (non-wide-gamut) panel. So technically, if you wanted SDR colors to display at their "correct" luminance values (at least for Rec. 709), you'd have to target a peak brightness of 100 nits, which I'm sure many here would find far too dim (even though that's what I personally calibrate all my displays to).

So to sum-up, I wouldn't sweat the ASUS factory pre-cal report, as even if your pre-cal was perfect out of the box (which isn't possible on almost any display type), dE readings are continually subject to the given meter tolerances, room temp, current monitor settings, panel aging, etc.

-I have not tested ULMB. Quite honestly I was curious how this stacked again the VG259QM. I'll play with this later but not much interest due to the glaring 240hz situation.

Gotcha, I have the i1Display but I was wondering whether the Asus calibration report is indicative of the panel having a better overall color accuracy with 0.5 or 0.7 than the mine that came with 1.03 or will I end up having nearly the same result when calibrated at home?

I mean 700 bucks isn't a lighthearted purchase when it comes even to gaming monitors so I'd like to make sure I'd get at least a good batch?

I just found tftcentral's report:



And that's mine:

If resolution is reduced, can go over 366 ? like here, where /4 resolution cut in both axis result in x4 refreshrate boost
