Acer Predator XB273K Gpbmiipprzx 27" UHD (3840 x 2160) IPS NVIDIA G-SYNC Compatible Monitor with VESA Certified DisplayHDR 400, Quantum Dot, 144Hz, DCI-P3, Delta E<1 (Display Port & HDMI Port), Black

One of the best monitors I’ve used thus far.

4k - CheckIPS - Check120-hz - CheckG-Sync - CheckYou would be surprised how difficult it is to check those 4 specification above without paying an obscene amount. The monitor market at the moment is quite expensive with the release of the 30 series Nvidia cards. 4k 120hz is now a reality. This monitor is $700 MSRP but you will be hard press to find it at that price new. I have gone from 1440p 144hz(TN Panel) to this monitor and the difference is night and day. Once you go 4k, you don't go back. TN panels have good response times but you can achieve similar response times with IPS panels and have drastically improved color accuracy and image quality. The games I've been playing feel like they've had a new life breathed into them.There are 3 different variants for the Acer Predator XB273K: Pbmiphzx, Sbmiprzx, and Gpbmiipprzx. Pbmiphzx is the original with an actual G-Sync module. Sbmiprzx is a refresh of the Pbmiphzx also with a G-Sync module. Gpbmiipprzx(this monitor) is a cheaper variant with the only difference being it lacks a G-Sync module but uses freesync technology to be G-Sync compatible.At the moment, this monitor is about $800 compared to its counterpart model Sbmiprzx which is about $1200 on Amazon. The difference? This monitor is G-Sync compatible while the Sbmiprzx model has an actual G-Sync module. G-Sync is a Nvidia branded technology that uses a variable refresh rate to prevent tearing in your image. Do a bit of research on G-Sync and you will experience a tear-free experience with a G-Sync module or G-Sync compatible monitor. With my current settings, I haven't experienced a single tear with a wide variety of games on this monitor. If G-Sync's primary goal is to get rid of screen tearing, well you can achieve that with this cheaper model no problem. There are no major discernible differences between the two models besides that. If a dedicated G-Sync module is worth $400 more to you, be my guest.

I was fortunate enough to get a rtx 3070 in March at a reasonable price. Last month, I decided to do research for a 4k monitor. After doing all of my research, I decided to purchase this one.Everything about this monitor is amazing. The specs are just right and in combination with my graphics card, helps deliver a stunning gaming experience. For reference, I am now running a Ryzen 9 5900x with a rtx 3070 graphics card and 32gig ram on a x570 master motherboard.I don't need a full 144mhz and with setting the best response time and gsync, I have no issues at all. I am still learning how to apply hdr settings properly, but I can tell a difference. And even without installing the flaps on the monitor, I am impressed.So far, this monitor handles Shadow of the Tomb Raider, Doom Eternal and World of Warcraft without any issues. I did have some screen issues with 4k on Rage 2, but I may have done something wrong with graphics settings.The menu is easy to work with and I didn't expect the led lights at the bottom of the monitor for added extra lighting. I am slightly disappointed with the color options but oh well.If you are looking for a good quality 4k monitor and still want the capability of gaming at 2k with high end specs, do not hesitate to spend the money on this monitor. You won't regret it.

Acer Predator XB273K is a complete disaster. Two of my monitors started flickering out of nowhere. After days of trying every possible fix, one stopped flickering, but the other kept going. Then, overnight, a dark, discolored spot appeared on the screen, making it unusable.Acer advertises this as a 4K, 144Hz gaming monitor – what a joke. The build quality is trash, and their customer support is nonexistent. I spent good money for a "high-end" monitor, only to get the worst piece of tech I’ve ever owned.If you value your time, money, or sanity, stay far away from Acer. This monitor is a scam wrapped in flashy specs. Don't make the same mistake I did.Worst monitor. Worst company.
