Beautiful display — be warned if someone starts screen sharing and they don’t use dark mode for whatever reason, it’s BRIGHT! I ended up turning the brightness down to 50% during a meeting and I haven’t set it back, still very vivid and easy on the eyes.
It’s connected to a DisplayLink hub to get the multiple monitors working on the M1. Had no issues getting this monitor to cooperate with the software and I can easily adjust the arrangement natively.
UPDATE: Are you getting a flickering monitor? If so you can turn of/on the free sync. I saw this in a internet article but that did not help in my case. What did help was to adjust the "Black Stabilizer" setting to anything but 50/100. This is under the "Picture" and then "Game Adjust" menus. I bumped it up to 60 (lightens the blacks up slightly) and that fixed the issue. Before doing that I rebooted the monitor and it would temporarily fix it until one day it did not. I adjusted this the Black Stabilizer and that fixed it for good. One interesting thing was this only effected my latptop as my xbox had zero issues. I run both though a KVM switch allows my monitor/keyboard/mouse to be shared among multiple devices.
Pros: This has made work so much better being able to see multiple windows next to each other. There is very little glare compared to the previous monitor I tried and the button for settings being on the bottom in the middle makes it so much easier to change inputs then if it were on the back. I was on a bit of a budget so I have not tried a curved monitor for comparison, but I don't find any problem with it being flat, but I also don't use this for any gaming. The color on this is great for the price. As a hobby artist I'm not looking for the best of the best, but it did need to be relatively accurate compared across multiple devices which I have found it's acceptable.
Cons: I personally think that the stand isn't the best in both quality and function. It's mostly plastic. Moving the monitor up or down was just okay. The stand really depends on the weight of the monitor and I don't know if it would hold up for a long time or not. I decided to put it on a VESA mount instead for more desk room anyways but still could have more thought into the provided stand in my opinion.
Side note: It was a weird set up to get the resolution correct with Mac OS. It's not so much the monitor but Mac OS but it was still a bit frustrating trying to google what the issue was. Also, who gives the user manual on a CD? The manual wasn't helpful at all but also had to search for my old external CD drive to even tell if there was anything useful in it.

Pros:
- Bocinas suficientes para skype / zoom, me evito la bocina adicional sobre el escritorio
- Monitor muy amplio mucho espacio de trabajo
- El brazo ahorra mucho espacio en el escritorio y permite acercar y alejar el monitor según se necesite
- IPS. Mi monitor anterior era un VA bastante decente, aún sí es una gran mejora en el ángulo de visibilidad
- 2xHDMI y DP, tiene ambos
- Resolución vertical 1440 - punto medio entre 1080 y 2160, tanto en resolución como en precio
Le falta:
- Ser curvo
- Carga de laptop con USBC,
- Side by side, para ver una PC del lado derecho y la Mac del lado izquierdo
- Accesos rápidos para cambiar modo video e input. solo tiene un botón para controlar. sería muy bueno un par de botones adicionales para estas funciones
Hubiera preferido el 34wp88c-b - similar, con brazo ergo, curvo y USBC, pero no está disponible todavía
The 3440 x 1440 resolution is top of the price range ($439-539) when you compare it to Gigabyte & Samsung (which they usually just offer in VA panel). You can easily tell the difference with this resolution (3440 x 1440) when watching movie and selecting 21:9 wallpaper.
Highly recommend this monitor in 2022. Don’t buy the one with only 2560 x 1080 resolution.

Highly recommend this monitor in 2022. Don’t buy the one with only 2560 x 1080 resolution.
However, this is a big plus is the speakers, they sound quite awesome, not boomy bass, but definitely better than most laptop speakers.
I like this for productivity just because of how wide it is and its great for content creation/video editing. ALso great for split screen if Iwant to have two windows side by side for programming and data analysis, web development.
