The XG321UG’s Mini LED backlight delivers tremendous light output in HDR mode. It is the second brightest computer monitor I’ve yet measured. Only the Asus PA32UCG, a $5,000 professional reference display, is a hair brighter.

HDR Brightness and Contrast

In this group, the XG321UG takes the HDR brightness contest over the PG32UQX by a comfortable margin. One might be able to tell the difference, but at that level, the screen is too bright to view directly when a full white field pattern is displayed. To get the highest possible reading, I measured a 25% window pattern. A full field measured around 1,300 nits which is very impressive.

The black level was hard to measure because the backlight is completely shut off when a full black pattern is displayed. By turning on a small info bug, I was able to measure 72,690.8:1 contrast, the second-best result I’ve ever recorded. With black levels this low, it’s hard to tell the difference between the top screens. Suffice it to say that a Mini LED monitor will deliver the highest contrast available from an LCD panel. To say that HDR looks amazing is an understatement.

Grayscale, EOTF and Color

In HDR mode, the color temp presets are still available, so you can calibrate if you wish. The only caveat is that the RGB settings remain the same for SDR and HDR. So, I used the same values for both modes and achieved excellent results. The brightest steps are a tad blue, but this error is almost impossible to see unless there are a lot of super-bright highlights. Nearly all HDR content will have perfectly neutral whites, grays and blacks. The EOTF takes a few slight detours from the reference line due to the action of the variable backlight. It has three modes, of which number two is the best and most balanced.

I measured HDR color against DCI-P3 and Rec.2020 and saw similar performance. DCI-mastered content will be a little over-saturated, but I doubt that will offend anyone. Rec.2020, the more commonly used standard for HDR, is also a little over-saturated until the XG321UG runs out of color just shy of the triangle perimeter. Hue targets are all in line, and saturation tracking is linear. There are no perfect HDR monitors, but this one comes darn close.

    It's comical! Who's paying these prices?!
    No one.

    Not only the price but what I would like to know what current video card can run games in 4K @ 144Hz at High settings? I recently purchased a 43" ASUS ROG 4K HDR monitor for $799 and I am quite happy. No way would I drop $2500 for a 32" monitor. I'd rather buy an LG C2 OLED TV for that price.

    I'm a photographer who shoots Fuji Medium Format (GFX) gear as well as Leica full frame. I'm a resolution junkie for my image files and have been using Asus 32- inch 4k IPS monitors since day 1 (many years).
    I'm not a gamer but do build my own high-end gaming PCs (with some help from a gamer builder friend) to use with Photoshop / Lightroom and working with and viewing my hundreds of thousands of images.
    Anyway, since the release of the 5 grand ASUS Mini-LED Pro monitors, I know I'm going mini-LED. But I wasn't ready to spend 5 grand for the past year or so.
    I shoot and edit no video, but am addicted to the 32 inch 4K IPSs monitors I have had for working with for the past 7 years with my big raw files. Viewing them on those monitors is incredible and I just can't imagine any serious photographer not having one these days (the basic 4K IPS LED that now can be had for under a grand). The fact that this mini-LED 4k 32 incher is only 1500 bucks is amazing.
    So I want a mini-LED 32 inch 4K Pro display, and this is it.
    I'm getting this monitor based solely on this review. I don't care about the gaming specs, but I can get everything the top-end Professional mini-LED monitors have for less money with this baby, and not sacrifice anything on the productivity end.
    For the past 7 years, one had to choose between Pro monitors or gaming monitors. This baby can give me the pro end while having all that gaming capability at my disposal (which could have other benefits even though I don't game).
    One question: Will this high-end HDR capability be noticeable or beneficial when viewing and editing 100 MB raw files in the LightRoom and Photoshop? Will it be beneficial when viewing the full-size 40 MB exported jpegs on the various viewing platforms for still images?

    :rolleyes:Reviewer did i great job reviewing this monitor but missed a CRUCIAL metric to evaluate; The Mini-LED halo-ing "glow" effect that is present in all Mini-LED displays. This effect can be noticed when moving your mouse cursor over a black or dark background.

    This was a huge missed opportunity during the reviewing process.

    If the reviewer happens to read this, please let us fellow consumers know the level of haloing (glowing effect) this monitor has. Thank you!

    Old games exist.
    Also with next gen coming soon, Minecraft RTX + DLSS will be a breeze.

    I play 8k on some games at high refresh rates.

    I would LOOOOVE to know how you manage to play in native 8k @ "high refresh rates".

    Not sure if sarcasm, curiosity, or genuinely never played old games?
    Oblivion, Fallout 3, Fallout NV, The Last Remnant. Wolfenstein: Enemy Territory can do x4 SS. Yes, 16k gaming. I'm sure there are many other old games out there beyond whatever I happen to play. Minecraft without raytracing. Minecraft WITH raytracing is not too far off either. (45fps w/ 4090ti x2 for next gen = 90FPS, turn down chunks from max or wait for gen after that and voila, path traced, 8k, 120fps.)

    In the future, DLSS/FSR2 will help make running current gen games at 8k easier. Of course, that would be for future hardware.

    My comment was part sarcastic and part frustration. Even though you may seem versed in computer hardware and getting high frame rates I will try to make this as clear as possible to dispell your previous claims so as to make more position more understanding....

    So......There are ZERO monitors or TVs as of 2022 that NATIVELY (inherently with no downscaling/upscaling trickery like DLSS) run @ 8K over 60fps. PERIOD. FULL STOP! Stated differently there is currently zero options to get an 8k display that supports over 60hz.

    Additionally, even if you are upscaling x2 on a 4k monitor with DLSS type tech you will stil be visually limited by pixel density of a 4k panel. There is NO point to upscale modern titles to 8k if the end user will not visuallly benefit from it. (this is different than post-processing over-sharpening which is a different conversation)

    So your base claim that you are able to run 8k at "High refresh rates" is NOT visually achievable with current screen technology no matter what computer hardware you have.

    There are no high refresh rate 8k displays and I claim to game at 8k high refresh rates. How is this possible? It's easy to infer it's DSR. DSR is DOWNSCALING. You RENDER at 8k and DOWNSCALE to 4k. You have it ass backwards because you are totally lost and have no idea what I was saying. Next time if you see a term and don't understand like "x4 SS", just ask.

    DSR is essentially a form of ordered-grid supersampling. TAA is not a perfect AA and has issues with ghosting and blur that can be worse in movement rather than being still. The blur decreases as render resolution increases even if the output resolution is the same. With supersampling, textures can also get sharper due to better texture sampling. Subpixel level detail improves. 8k render downscaled to 4k is not as good as 8k render displayed by 8k monitor, but it beats 4k render displayed by 4k monitor. Supersampling is not new. Do some basic reading.

    Example of subpixel/pixel level detail:
    1080p native: https://techreport.com/r.x/dsr-capture/mill-1920.png4k DSR (Render 4k, downscale to 1080p): https://techreport.com/r.x/dsr-capture/mill-3840.png
    Notice how the rope is straight up missing on right hand side at 1080p native. This is easiest to see in fine lines at a distance. Fences, ropes, to lesser extent grass at a distance. And also, "DLSS hype tech"? ...Really?

    You lack basic information. That's all I got to say, I'm done.
