A display like this, with an extended colour gamut for HDR, should not only cover 100% of the sRGB gamut (the standard for Windows PCs) but a high proportion of the AdobeRGB gamut too. The rest of our objective image quality testing is done with the Spyder5 Elite colorimeter and software and the first test it performs is to see how much of the standard colour spaces a display covers. It can deliver a contrast ratio of 1065:1 which is on par with any other good-quality IPS screen. Instead it’s the native contrast of the panel that matters and thankfully the XB273K is decent in this regard. All these figures use the same technique and they’re all just as meaningless. It’s for this same reason that we always totally dismiss any TV or monitor contrast claims based on dynamic contrast. While the backlight can technically vary, because it has no zoning even just a few illuminated pixels results in the backlight lighting up fully. The results made our life considerably easier as all these various settings made absolutely no difference to contrast in real terms. That is, with HDR turned on in Windows, with HDR turned off but with the SDR Variable Backlight setting turned on and with the variable backlight setting turned off. We tested the display in all three of its main backlight-varying modes. We primarily use this setup to test for contrast levels as the Spyder5Elite under reports this figure. We start our testing with the Xrite iDisplay Pro colorimeter, which is used in conjunction with a piece of software called Displa圜al. These are devices that are placed in front of the screen and measure the display’s output. We test with two colorimeters: the Xrite iDisplay Pro and Spyder5Elite. Moving on from our subjective testing to our objective testing and the XB273K largely continues to impressive. Again, they’re not enough to make this display a must-buy for HDR, but the extra vividness is nice to have for games and videos that support it. Switch between the high and low colour gamuts (by turning off SDR colours sRGB or switching to HDR mode) and you can immediately see the extra pop that the high gamut colours bring. Colours are accurate, viewing angles are great, it has a reasonably deep contrast level and that 4K resolution can look stunning. Subjectively, right out of the box this display looks fantastic. 6650K from the spyder, does that prove anything?If the Acer XB273K doesn’t entirely convince when it comes to its HDR and gaming credentials, one area where we have very few complaints is its overall image quality. I measured X and Y using the visual white editor on a 2nd monitor and got approx 6350K from the iDisplay and approx. I’m sorry but I don’t know what else I need to do to setup measurement mode to get the correct settings for the spyderX, I can’t find any other options. From the 4 choices in the firmware, its not standard white LED, or either of the two wide gamut modes. I installed the argyIICMS drivers for the Spyder and intentionally selected generic mode as datacolor say to use for older standard gamut displays with CCFL. Nevertheless, I used them in the past but found the generic CCFL gave more reliable results. There is a spectral correction for the FS2331 but as White LED IPS, not the correct CCFL and VA panel. I don’t know if it’s 3nm or better or how to find out. One reason I choose it(over LED) back in 2011. This reply was modified 1 year, 4 months ago by Kobern. This puts back any hope of a new monitor for now □ I think I got a duff datacolor spyder? It doesn’t seem to measure blacks properly, gives the wrong contrast for the VA panel, and also gives a pink cast.Īs all the repeated advice, I need to return and future budget for an i1Display Pro. calibration from spyder verified using spyder MWP=6523K, then verified using x-rite MWP=5949K calibration from x-rite verified using x-rite MWP=6496K, then verified using spyder MWP=7178KĢ. If anyone is interested, or it helps, to show the differences between x-rite i1display and datacolor SpyderX, I verified each instruments calibrations with both:ġ. ![]() Spyder => hint/essence of salmon pink colour balance (feels a bit pink)Ĭomparing a spectrally neutral grey card (lit by daylight) to each RGB user presets the i1display greys seem right/more neutral. ![]() I1display => hint/essence of matrix style colour balance (feels a bit green) Out of curiosity used both i1display and spyder – they vary in measured white point by approx 500-600K!!
