For its cost, it is the best option that has been released. Tested with MSI gaming laptop for games, Macbook Air intel and Macbook Pro M1 for office work without any problem.
As others have mentioned, the viewing angle is not very good, but if you are viewing from the sides, it doesn't affect much. The colors are quite good, compared to an older LG Ultrawide VA that I had, which had some issues with black, but maybe due to the refresh rate, the overall image is better. Of course, for full 144MHz, you need to connect with a display port, otherwise with HDMI, it goes up to 100MHz. There is also a setting to display the refresh rate on the screen. I haven't adjusted the colors, I play with the preset settings, which are plenty.
The menu is very good and easy. The picture by picture mode is very easy, I tried it with two laptops without any problems, you just need to manually change the resolution of the devices because sometimes it doesn't scale automatically. Calculate a resolution of about half the maximum, for example 1720 x something.
I haven't tried the gaming modes and other modes.
The stand is very stable, but it has large feet. Since my desk is somewhat narrow because it is L-shaped, I have supported it on an arm to save space. Although the arm is good, I have lowered it a lot to minimize movement, it's at the weight limit, but so far it holds up.
In terms of connectivity, it has the basics, many outputs but nothing extra. It doesn't have speakers, only a headphone output, like other monitors, it is recognized as speakers by Windows/MacOS, so don't get confused.
Also, a good thing is that it has the best nominal power consumption in its category, it is one class better than the others, but I haven't verified it, I don't care that much. For office work, I leave it in eco mode, for more demanding games, I change it.
Overall, it's a great value for money. Beyond that, if someone is more demanding and wants to increase performance, they will have to spend at least twice the amount to start with and see. So decide accordingly.
The only thing I personally miss is that it's not curved, but you can't have it all. Obviously, once you go ultrawide, you don't go back.
EDIT: To add that I quickly tried the AOC application, but I didn't see any changes, maybe something didn't work right away, so I didn't bother with it further. As I said, for the use I have, the menu with the settings covers me.
