### ⭐⭐⭐⭐⭐ Good Monitor for Macbook Air M2 for the $$
*by C***. on March 29, 2023*

I purchased this for use as an external monitor with my Macbook Air 2022 M2 for general business use - email, web, spreadsheets and running business applications. I haven't used it for gaming. I shopped around in this price range and was interested in this monitor because it was UHD, has height adjustment (many in this price range surprisingly didn't) and had video input connectivity via USB-C to USB-C. As a bonus, it has some docking station features with downstream USB ports (although not USB-C). The USB-C connectivity may not work for older computers so you should do your research.I’ve only had this monitor for about a week but so far I am very happy (I will update if I run into problems). It has decent resolution/picture for the price and the USB-C connectivity for video works great. Since the single USB cable for video simultaneously charges my MacBook, I don’t need a separate power cable attached to the MacBook. This means I can unplug one cable and take my computer with me. When I return, I can plug in one cable and I’m ready to work at my desk. I haven’t used the additional downstream USB ports yet but it is nice to know they are there.There is an annoying issue with a 15-30 second delay for the monitor to pick up the video signal when I awaken the MacBook from sleep. When I return from a break I often have a blank screen and then have to move the mouse or press a key and wait for the video to return. I have been experimenting with screen saver and sleep times on my Mac to find the best solution. I have not yet been able to determine a way to speed up the monitor reconnect time after sleep.The product documentation included was mostly safety warnings in multiple languages with no user manual. Fortunately, I had downloaded the user manual from the manufacturers web site while shopping for this unit. That manual is sparse with grammatical errors and doesn’t provide much explanation of settings other than how to change them (about what I expected). Most are self-explanatory but I had to look up a few online.This unit arrived without any damage and worked pretty much out of the box when I plugged in the USB-C cable. Overall I am very pleased.

### ⭐⭐⭐⭐⭐ Great for productivity and video
*by K***H on August 20, 2023*

I have a 2 monitor set up that I use and switch between my personal and work computers. My other monitor has a KVM, so that makes it super convenient. Anyway, about this monitor.I was skeptical of this monitor at first because it is a VA panel. Turns out the picture quality is great. If there are any pixels burnt out, I couldn’t tell you as they are too small for me to see. This is my first curved monitor, and I have to say, I think I personally prefer curved monitors now. Especially whenever monitors start going above 27”. It just makes everything easier to see, for me. I’ve watched 4k videos/movies on this monitor and it’s flawless, with vibrant colors. I didn’t need anything super fancy or expensive for my secondary monitor, just something that works. 60Hz suits my needs.I did a lot of research between the VA panels and the IPS panels. The IPS monitors cost a lot more money, and for my primary use, which is office productivity, this is fine. If your primary use case is gaming or something with high accuracy color reproduction, then you might want to look at other monitors. I’ve played WoW on this monitor, and it worked fine, but I prefer my other monitor, which was made for gaming and higher FPS.After a year of owning this one, I am very pleased with it.Update: I have an M1 Mac Mini and running dark mode causes this screen to flicker, quite a lot. I have to run it in light mode, which I'm not a fan of, but this is not a problem of this monitor. The M1 Mac Mini, for some reason, doesn't support dark mode when running through HDMI. I haven't tried running this through USBC, so that may solve the issue, as I stated in my earlier review, this is my secondary monitor. I just wanted to provide that update in case you happen to have an M1 Mac, I can't speak to models other than the Mini, that you may experience this issue and it is your computer, not the monitor. My rating does not change as this monitor continues to be a great purchase.
