    • Best budget 280hz monitor out there
Size: 24.5-inch Style: FHD 280Hz
This monitor is really good, been using it for 6-7 months (67) and it's really good. Although on warm light settings there is a lot of ghosting and doesn't look that good so whenever I have a headache I'm not able to use warm light settings cause it makes the headache worse. But overall great monitor. ... show more

    • Good starter monitor 😄 Good starter monitor 😄
Size: 24.5-inch Style: FHD 280Hz

This monitor is pretty good for the price it’s set at. I love the 280 hz I can get and while the color quality may not be the best on its own, I modified it with my AMD software for pc to have really good colors to make it pop more. The size is also not too big or too small, making it pretty compact. Overall a great monitor to start with in my opinion 🙌 ... show more

    • A solid investment in gaming gear nonetheless.
Size: 24.5-inch Style: FHD 280Hz
When I first got it I realized the colors were really bad. But I quickly found out that increasing the brightness fixed the color issues. It was set to about 80% brightness, should've been at a 100%. Resolution I don't really care about. The reason being is I bought this to play rocket league and rocket league in 4k just simply isn't worth it which is why I got a 1080p monitor knowing that. Also resolution these days isn't worth it since it is not like you can play most games anyways in 4k and expect high fps. I didn't really care that much for the accessories it came with. It came with an hdmi and display port cables. They were very short but it didn't really matter since I already had some plugged into my pc that were way better. The thickness of the monitor is relatively thick but doesn't matter since this is going on my desk and my desk is huge. I bought this because as I mentioned previously, I wanted to play rocket league from 120 fps settings to 240 fps settings and to be honest I am not at a stage in the game where I can notice a big difference in settings. The only things I really notice is that the game is a lot smoother for whatever reason but that is it. With that said this monitor is probably a waste of money for me, but a good investment in my gaming gear nonetheless. ... show more

    • Cheap in all the places that don't entirely matter
Size: 24.5-inch Style: FHD 280Hz
I bought two of these monitors and had an issue with the Display Port on one of them and had to get it replaced. The DP cables that come with the monitors kinda suck and I would recommend buying cables to replace them cause otherwise I had issues with artifacting. It's a great value however and the refresh rate feels high and I don't really notice ghosting too much. I did the UFO test and with overdrive on the ghosting is definitely there however pretty minimal which is impressive for a monitor of this price. The monitors are pretty thick, and their included stands aren't great but they work with minimal Y axis tilt adjustment, no X axis tilt at all. Nor is there any vertical movement with them. They cheaped out on basically everything but the monitor part of the monitor. Works great in games like osu! and CS2. Size is fine, maybe a little small but its fine for me. Overall 4/5, cheap in all the places that don't entirely matter. ... show more

    • Has amazing FPS and latency.. HDR is absolutely astonishingly beautiful :)
Size: 24.5-inch Style: FHD 280Hz
These are great monitors, we baught 3 of them.. Running them at 280hz and lock the FPS at 277 to prevent clipping.. very low Latency.. and the HDR is absolutely the best thing since Realtime raytracing! We run ours on RTX 4060 8GB and are able to maintain 277FPS without issues. Gaming performance is amazing in most games.. Eventually we want to upgrade to 500hz monitors but would need 5080 16gb of higher cards to put out enough FPS to make those monitors useful. Plus 500hz is cost prohibitive due to the RTX 5080 or higher 16gb requirements. ... show more
