Results: Color Gamut And Performance

There are some interesting things to observe in the XL2430T’s FPS 1 mode. First off, the green primary is largely untouched as far as the CIE chart is concerned. Each saturation level is pretty much on-target. Green luminance, however, drops progressively more as you approach 100 percent. Yellow is significantly under-saturated, but its luminance rises to compensate. Red is mostly over-saturated until you get to the edge of the gamut where it’s just about right. The magenta and cyan secondaries are both over-saturated and off in hue. And blue is under-saturated except for the 100-percent level, which is near-perfect. It all adds up to a strange mish-mash of color that just doesn’t look right.

Switching to Standard improves the situation, assuming that a correct sRGB gamut is your goal. Without calibration, red, magenta and blue are still under-saturated. But at least the hues are correct and the cyan/green/yellow end of the gamut is good. The luminance chart shows that proper compensation is applied to the under-saturated colors.

Since we barely moved the RGB sliders, the improvement shown above is mainly due to the change in gamma from preset three to five. Now we have an almost perfect result that would rival many professional displays.

We return to the comparison group:

Our calibration changed the color gamut from 2.4dE to an excellent 1.15dE. It’s not an earth-shattering difference, but we could see it in real-world content. If you can’t do an instrumented adjustment, just use the Standard picture mode with Gamma 5 and you’ll have an almost-perfect image.

Gamut Volume: Adobe RGB 1998 And sRGB

If you need to do color-critical work, the XL2430T can fill in nicely for a much more expensive pro display. The .34 percent deficiency we measured is not visible to the eye or even on the charts we use to calculate gamut volume.

    Me IPS all the way. One you switch to an IPS display you are done with a TN panel

    Don't be interrupted by want type of panel it is.
    TN and IPS both have there own advantage. TN for low response time and relatively high refresh rate, whereas IPS has better color reproduction and viewing angle. However, IPS panel generally has long response time, which might cause ghosting when gaming.

    For XL2430T TN panel which might seem bad color reproduction, the color is actually fine and it can be adjusted by "Color Vibrance" mode. It's a great choice for you.

    Nearly $400 for a 24in 1080p monitor, that's quite expensive.

    Wow. Some people don't bother to read the article. The reviewer clearly states that the ONLY difference between this TN panel and an IPS panel is viewing angle. How is this a problem unless you're using more than 1 monitor? How many people sit and game when they don't have their monitor right in front of them? EVERYTHING ELSE about this monitor as far as performance is concerned completely out-classes IPS panels. Stop complaining, read the full article and unless you have anything constructive to say, rather don't say anything at all. Commenting that you're waiting for an IPS panel or wouldn't ever go back to a TN panel is rather useless. As for me, I think the price is very reasonable for this monitor, given its excellent review on everything that matters to a gamer.

    I stopped reading after "TN panel". Not even worth my time.
  • wishmaster12
    all your paying is for 24 more hz, I bought a 24in 120hz for 250$
  • chenw
    I stopped reading at 'IPS', not even worth my time.

    Seriously, after comparing the VX2770 and swift (which is a classic IPS to TN), I wasn't even sure what IPS was all about, the IPS had much worse BLB and didn't look that much greater (granted, it was probably a bad IPS panel).
  • chenw
    Just to clear up, I know the monitor in review is a TN panel

    Is it known if this monitor is FreeSync-compatible, or can be upgraded to be FreeSync-compatible?

    Thank you
