According to the reviews I was a little afraid of the monitor, but there's really nothing to worry about, you just need to be careful with the wiring
1) sharpness, contrast - if I had the monitor through the docking station, the max resolution was 2560*1080/50Hz, and the dock only increased it to 3440*1440 at the same frequency and the sharpness was less, but even so it was acceptable, for the eyes it was paradoxically much more pleasant. If the monitor is straight on and the dock is used only for the 2nd and 3rd monitor and other peripherals, this 34-inch is beautifully sharp, contrasty and easily readable in all its parts, in the graphics card it can be played to perfection even at 100Hz (150Hz horizontally and 99 vertically). Except, and this is why I bought it, I have to have a blue light filter, and the white set to yellowish so my eyes don't hurt, so I purposely devalue the image a bit. The monitor is 95 cm (bent) - 115 cm (straight) from my eyes, contrast at 25%, brightness at 15%, Gamma 1 and DCR off.
2) sound - sure, it's not Magnats - but for regular work, Teams and background music and movies it's OK. No need to switch on BT speakers. In addition, it is possible to tune it through the sound system, the music from it does not offend, if you do not expect Hi-Fi level.
3) between my three monitors I can set the master and slave to any of the three without any problem, so it's bullshit that it can't be done (WIN11)
4) graphical outputs (AutoCad, Corel, Sketchup) are not distorted like on the rounded CU variants
5) for normal office and graphic work, Photoshop, AutoCad, InDesign, SketchUp, DaVinci, and for the occasional movie, the monitor is perfectly fine
6) you will be pleased with the setup options and LowBlue mode as well as USB options for connecting other peripherals.
7) as a replacement for an older 24 AOC monitor definitely a step forward and at a reasonable price
8) small depth and light weight with VESA 100x100 hanging
