Great picture, quality, and response time. Only downside is the stand feels cheap. All in all very great quality monitor for the price

DO NOT BUY. 3 MONTHS OF USE. PANEL SHOWS VERTICAL PURPLE LINE DOWN THE MONITOR. OTHER REVIEWS SHARE SAME EXPERIENCE. I'm hoping that support fixes this, but I have a feeling they are going to make it as difficult as possible. In no way should I have to pay for shipping for something like this. Do not make the same mistake and buy an off-brand monitor like I did. I have a feeling that if I get a replacement I will just end up needing one again later. Extremely disappointed as up to this point it was working perfectly fine.

Right off the bat I want to address the deceptive marketing with this monitor, though you can turn on HDR and play HDR content, this panel is not actually HDR10+ capable, it simply supports HDR content. The biggest issue here would be this monitor only supports 8-bit color depth, HDR10+ requires 10-bit or higher. Higher color depth prevents banding because it allows a monitor to display more shades of colors meaning you get more colors the higher your color depth is. It's also not a particularly bright monitor, 300 nits is what is advertised which seems about right. HDR10 content is typically mastered for monitors with peak brightness of 1000 - 4000 nits, ideally with HDR10+ you have local dimming or self-emissive pixels. This screen does not have any local dimming and has a VA panel. Though this is not true HDR it's not a terrible picture, contrast is good and colors are still vibrant. Being a VA panel this will offer higher contrast than IPS or TN panels but can't compete with OLED or monitors with good local dimming. Watching videos on this monitor is pleasant and everything is nice and sharp. Gaming on this is good, using DisplayPort you can get the full resolution and refresh rate; however, if you have to use HDMI you will be capped at 144Hz 1440p, this is still a high refresh rate, and most people won't notice a difference once you get past 120Hz. With this particular panel I didn't really notice any black smearing while gaming which has been a problem for VA panels in the past. That's not to say there is no smearing, it's just not as bad as I've experienced, I assume this is because there is no way to disable overdrive on this panel. The overdrive menu is listed under "Response Time" and you have Normal, Fast, or Faster. User interface is good, it has a joystick to navigate the device menu. The user interface is pretty basic and allows you to change different settings like brightness, sharpness, contrast, etc. Ergonomics are pretty poor for the included stand. You can adjust the tilt of the monitor and that's it. You cannot adjust angle, height, or pivot with the included stand. You do get Vesa mounting holes though so I would recommend picking up a cheap monitor arm for this if you want adjustability. Overall, I like the picture for SDR content and found it perfectly usable for gaming. Do not get this if you want HDR capability as again it is not actually HDR. I'd recommend a monitor arm as well.

I ordered this monitor for use with my gaming desktop computer, and when I first saw the listing, I thought it might be too good to be true. Fast forward a couple of months, and I can safely say that, at least for me, it is a little too good to be true. The monitor comes boxed with a DC power adapter, which is different than your typical everyday monitor, which typically uses AC power. While this monitor is nice to look at, and the screen looks pretty nice when not doing anything graphics intensive, once you get into heavy gaming, with high frame rates, it starts to look more like the budget monitor that it is. At higher frame rates, I tend to get a bit of ghosting, but games with lower frame rates seem to be alright. There have be other times where the monitor was off, rather than standby, which is where I leave it, as I never turn it completely off. The times that it did this, I was not able to just turn it back on using the power button; I had to completely pull the power adapter out, wait a minute or so, and then plug it back in. Once I did this, the monitor would turn back on. I'm not sure what the cause of this is, but it doesn't seem normal to have to do this, and seems like maybe something is shorting out, or maybe there's a bad solder joint that opens up, either in the power adapter or the monitor itself, when it gets too warm. Either way, this hasn't happened during use, so I'm thankful for that. Other than these issues, the monitor is okay to look at for typical purposes, but again, where it really matters, and likely the reason anyone would buy it, it seems to fall short. Certainly, I purchased this 165Hz 1440p monitor for gaming, yet it doesn't look the greatest while doing so. If you just need a monitor to satisfy the need for a monitor, then this would probably do, but if you're a gamer, I wouldn't necessarily recommend this one.

Looked great, but thirty minutes into using a random purple line appeared across the screen. LAME.
