  • Literally as described!
Style: QHD Pattern: Ergo Stand
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). ... show more

  • Wonderful Monitor. Spectacular clarity
Style: QHD Pattern: Ergo Stand
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. ... show more

  • Super easy installation, great appearance
Style: WQHD Pattern: Tilt and Height Stand
Currently my main monitor with a couple ancillary ViewSonic monitors. Mounted this one pretty low and it takes up too much space for me to keep the laptop lid open — 3 displays are enough and the 13” MBP from work is an eye strainer anyway. 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. ... show more

  • Works great for working from home
Style: WQHD Pattern: Tilt and Height Stand
I bought this for working from home during the day as a software engineer and using this at night for digital art. This was my second test of a 34" ultrawide, the previous samsung was terrible for digital art, but it was also a cheaper VA model. 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. ... show more

  • It is a great monitor!
Style: QHD Pattern: Ergo Stand
This monitor is great! I do want to clarify for any that are wondering, there is a "kind of KVM" feature, but it essentially uses network connectivity and a software application that needs to run on both devices intended to use your keyboard and mouse between in a kvm style manner, the screen snapping software is great as a side note but I don't use the kvm as I have a USB switch and would rather not use peripherals over network so no comment on that.... even if this device has no kvm utility, it is still very worth the amount I paid for it and the stand it comes with is amazing. Just wish the display cable it came with was a bit longer and that it came with the USB extension cable like it did in the Linux tech tips video, it does not in the model I bought, but that is cheap and I had a few prior. ... show more
