    Literally as described!
    I wanted to wait a week to review this product. When it arrived the set up was very easy and straightforward (some people may need assistance with the desk mount as it is fairly heavy/sturdy). As I am starting medical school very soon I wanted an ultrawide monitor for all the tasks I know will be demanded of me. After literal WEEKS of research (ie, youtube, Reddit, google, amazon reviews, etc) I decided that this monitor was in the "sweet spot" of price and quality -- boy was I right! I connected this to my M1 Macbook Pro (see picture) and the factory settings are very very good. However, I ran a calibration on the screen and it adjusted the monitor even better! I love this monitor so much and I do not think I can go back to regular monitors after this. I wish it had a USB-C connection, but I cannot complain still since I use a USB-C to DP 1.4 cable.NOTE: M1 Macbooks may have issues with external monitors -- this is not the monitor issue it's a Mac issue. The workaround I use is hot corners (google it if needed) as well as extending my screen time out time to like 30 minutes. Additionally, manually putting the MacBook into "sleep" mode when leaving allows you to wake it up on the external monitor without having to plug/unplug the USB-c and/or restart like so many people have been having issues with. Lastly, get a USB-C (thunderbolt) -to- Display Port 1.4 cable if you are using a Mac. This allows you to obtain the 75hz that is advertised; otherwise, if you use the USB-c to HDMI connection you will be capped out at 50hz (still looks good IMO).

    5.0 out of 5 stars Wonderful Monitor. Spectacular clarity
    Reviewed in the United States on January 12, 2021
    There is everything to love about the 34 inch 780. The support arm is so flexible, perfectly counterbalanced for easy adjustment. I will never buy a monitor on a stand again. The image is calibrated spot on . Colors are clear, strong and detailed. The 1440 resolution is the 'sweetspot'. 4k is an awful drag in the system if you do video conferencing. GO-TO-Meeting runs like a dog when my colleagues with 4k monitors share their screen. The 1440 resolution has no problems. The wide screen allows two windows open for app and data comparisons which is very helpful for software implementation . You need to use a DP cable to get the 75 HTZ rate, but 50 that I got with HDMI seems equal to the 75 htz rate. I switched from HDMi to Dp and saw no difference. I would buy this again in a heartbeat. I love the 34 inch and am very very glad I did not buy the 27 or 32 inch versions.

    Reviewed in Canada on October 22, 2022
    Awesome widescreen for multitasking. It is a decent price to value ratio. The sound from the monitor is decent considering it is just coming from the screen. I wished they had more PIP and PBP capabilities but otherwise I am happy with this screen.

    I haven't found a easy way to auto switch between available signals.

    I'm happy with the screen quality and build quality.
