What is the best 4K monitor for the Xbox Series X?

Respectfully, I'd consider another option because the M28U has some HDR limitations that might disappoint you. If you want better contrast, the LG 27GR93U-B 27-inch UltraGear UHD 144Hz Gaming Monitor or the Sony INZONE M9 27-inch 4K 144Hz Gaming Monitor are way better for HDR performance on Series X.

Honestly, if you're worried about HDR performance without spending a fortune, I've gotta jump in with a reality check. True HDR on monitors is pretty rare unless you're dropping huge cash on OLED or Mini-LED tech. But, for a solid balance of price and reliability, I'd suggest looking at the Samsung 28-inch Odyssey G70B 4K UHD 144Hz Gaming Monitor. It hits that HDMI 2.1 sweet spot for the Series X and the build quality feels a bit more robust than some budget brands.

Another one I've tried is the ASUS TUF Gaming 28-inch 4K 144Hz DSC HDMI 2.1 Monitor (VG28UQL1A). It's basically a tank. The ELMB Sync tech is great for motion clarity, though the HDR is still just 'okay' because it's edge-lit. Just a heads up—always check for firmware updates immediately cuz they fix a lot of early HDMI handshake issues. It's a safer bet for your money imo. gl with the setup!!

In my experience, Gigabyte M28U 28-inch 4K 144Hz Gaming Monitor is basically the king of value for Series X. HDMI 2.1 works perfectly and it won't kill your wallet. Seriously, just get it. 👍

So basically, besides just picking a model, you really need to think about the DIY calibration side of things. Factory settings are usually way too bright or have weird color tints that mess with the HDR look. You dont really need to pay for a professional service to come out and tune it, but you should definitely do a thorough self-service setup instead of just plugging it in and hoping for the best. It is a bit of a process but it makes a huge difference for long-term reliability.

• Use the Xbox HDR Calibration app as your first step to set the black and white clips.
• Check for firmware updates manually on the manufacturers site to fix any HDMI 2.1 handshaking bugs.
• Run a screen uniformity test in a dark room to check for any manufacturing defects early on. I have been looking at the Dell G3223Q 32-inch 4K UHD Gaming Monitor lately. It seems like a safer, more conservative choice because Dell is usually pretty good with their exchange policy if you find dead pixels or issues during your own testing. Its not the flashiest brand, but the build quality feels solid. Just be careful with the out of the box settings because it might look a bit dull until you spend some time tweaking the profiles.

Bump - same question here

Honestly, I totally agree with the point about HDR being a bit of a letdown on most of these. It's basically just a sticker on the box unless you're dropping a couple thousand on a high-end display. Like, I’ve been doing some market research lately because I wanted to upgrade too, and it’s sooo hard to choose because the brands are basically just fighting over the same specs. I think I read somewhere that most of these mid-range 4K monitors actually share the same panels from the same manufacturers? Not sure but it would explain why the performance is so similar across the board. Tbh, it feels like you're mostly paying for the brand name and the menu layout at this point. I've noticed that ASUS usually feels a bit more "gamer" and rugged, while LG and Sony seem to go for that cleaner, minimalist look. If you aren't in a massive rush, I'd maybe wait a bit because IIRC prices have been dipping lately as newer OLED tech gets cheaper. Just make sure whatever brand you pick has decent firmware support because some of those budget-friendly brands are notoriously bad at fixing bugs after launch.

No way, I literally just dealt with this yesterday. Small world.
