Review on Acer CG437K Pbmiiippuzx 4K Display, 144Hz, Backlit, Compatible with DisplayHDR 3840x2160 by Patrick Tomlin

I originally gave 3 stars; But now that I have a really good monitor I had to reduce it to 1. There is absolutely no reason to buy this monitor for desktop, gaming or video. If you have enough cash to buy this and a 3080 for 4K 120Hz, please spend the extra $500 on an LG CX or other OLED/QLED. The LG CX I got instead has 0 bleed-through, 0 ghosting and still decent enough HDR brightness. I can use it for desktop text with perfect definition. Pros: Dimming at the edge of the screen is minimal/meets my standards. Angled viewing and looking at the corners of the screen didn't result in color distortion either, which wasn't okay for my liking. Cons - It's a desktop/gaming monitor (120Hz, G-Sync); but this panel is completely unsuitable for him. It has fairly strong transmission from one pixel to neighboring ones. This makes reading small text on your desktop so difficult that it feels like you're blind. Why spend money on a 4k render and monitor when the blur is so bad it could be 1440p?! This statement applies equally to the desktop, games and films. There's also the dreaded ghosting, meaning images moving across the screen leave afterimages for a lot longer than they should. A 3px wide line becomes 15px wide when it's moving, and then gets back to 3px wide after it stops: incredibly distracting! You're effectively using 720p every time the scene moves. Turning backlight flicker on is actually worse as you get flicker, less brightness and no G-sync while still getting 3 or 4 more noticeable overlay afterimages instead of blur. Finally, and this is a bit more technical, there is a moderate level of vertical "screen door" artifact that only appears when objects are moving. This is because each pixel's red LCD elements don't have enough power to change color quickly, causing all red elements to dim as the image moves. So every time the scene moves, it appears that someone has closed the screen door in front of the image; everything is broken up by vertical lines, like a striped printout from an old printer. As soon as the scene stops moving, everything smoothes out again. Aside from the jarring effect and objective loss of fidelity, this suddenly makes the image feel like a 2D cardboard cutout with every movement of the scene.
