Windows 11 bug is messing with colors on some HDR monitors

Windows 11 suffers from a bug which is causing colors to be rendered incorrectly – with the most common error cropping up being white showing as yellow – at least with some HDR monitors when running certain image editors.

As Tom’s Hardware spotted, this is something Microsoft is actively investigating, and the software giant has flagged it up in the support document which lists the current known issues with Windows 11.

Microsoft observes: “After installing Windows 11, some image editing programs might not render colors correctly on certain HDR displays. This is frequently observed with white colors, which could display in bright yellow or other colors.

“This issue occurs when certain color-rendering Win32 APIs return unexpected information or errors under specific conditions. Not all color profile management programs are affected, and color profile options available in the Windows 11 Settings page, including Microsoft Color Control Panel, are expected to function correctly.”

The color glitch affects those running Windows 11 version 21H2, and Microsoft says it is working on a fix right now, with the expected timeframe for delivery being late January.

Analysis: Not so mellow yellow, but at least that fix is coming swiftly

The expected arrival date of late in January could mean we see this fix bundled in the cumulative update in preview (testing) for that month, which will see a full release come Patch Tuesday in February. So, if this bug is one which is plaguing you at times – and we imagine seeing white as ‘bright’ yellow (not even just a faint yellow) would be pretty jarring – at least you won’t have to suffer with this for much longer (assuming the cure arrives as planned and is successful, naturally).

While annoying, at least this particular bug is confined to a fairly limited subset of Windows 11 users in terms of it just affecting some image editors, and only with certain HDR monitors.

It’s a fairly niche problem, then, but more widespread Windows 11 bugs are an ongoing theme for Microsoft, and as we recently pointed out, it’s disappointing to see quite a lot of glitches popping up. Particularly ones which pertain to fundamental parts of the interface like File Explorer, as these contribute to the general impression of the new operating system being released before it was fully ready. Before it came out, we felt Windows 11 was a good opportunity to change the perception of Windows 10 being bug-ridden, but thus far, that hasn’t panned out.

Its Ultra-Slim Aluminum monitor, for example, is hailed for its sleek, ultra-thin bezel design and ultra-wide viewing angles at 178°. This monitor isn’t particularly feature-rich – there are no built-in speakers, for example – but its IPS panel allows for extremely sharp image, FreeSync tech reduces screen tearing and Monoprice’s Pixel Perfect Guarantee gives it vibrant color performance.

If you’re looking for a 4K monitor for gaming, ViewSonic’s XG2700-4K is the perfect fit. It is not without quirks: the screen brightness could be higher, the red on black trim is an acquired taste, and it has no built-in speakers. On the other hand, you get amazing picture quality, quick response time, accurate color performance, multiple ports, and a versatile stand for multiple viewing angle options. Its most notable feature is AMD FreeSync to prevent tearing and ensure that your games are running smoothly. Of course, the picture-in-picture and picture-by-picture modes are also helpful because who doesn’t multitask nowadays.

IPS displays may offer better viewing angles and color representation, but a good TN panel makes for a much better gaming monitor, thanks to much faster response times, higher refresh rates and affordability. This is why the AOC U2879VF has a 1ms response time and a refresh rate of 144Hz for a low price. If you can forgive the restricted viewing angles, the occasional flickering at 144Hz, the absence of a USB port, and the ho hum color performance, this AMD FreeSync enabled monitor is for you.

Not only is it a 27-inch 4K monitor with HDR, but it also has a refresh rate of a whopping 144 Hz. If you have the horsepower, you can play games in 4K competitively without losing an edge to the person playing in 1080p. But, as you may expect from a spec sheet like this, it’s very expensive – but if you need the tech, it’s definitely there.

You’ll need a bigger desk with 43UD79-B’s hefty, 42-inch screen. Unfortunately this bigger than life screen might also be darker around the edges and a sluggish refresh rage. However, this 4K monitor’s other features will more than make up for its flaws. The screen split software, for one, allows for a range of screen configurations. This, coupled with its four HDMI inputs, a DisplayPort 1.2a port, and a USC-C port, will let you effortlessly run multiple devices at once. Along with its true IPS screen, color-rich display, and FreeSync compatibility, you might just be getting a bargain.
