Cons
Con Limited connectivity
This monitor has two HMDI ports, which is pretty good. However, it misses other display inputs such as DVI or Display Port, making incompatible with older computers.
Con Lack of support for ultra-widescreen in (old) games
A handful of games do not support 21:9 aspect ratio by default. Some examples are Overwatch, Fallout 3, and Starcraft 2. If this is important for you, it is recommended you test this issue before getting this monitor. But there are solutions: you can either install fixes (only available for some games) or play in windowed mode, using a different aspect ratio.
Con Slow response time
A response time of 5 ms on a gaming monitor is pretty awful. Considering its refresh rate, it is understandable but not acceptable. Note that this response time is from gray-to-gray.
Con 720p and 1080p videos are sandwhiched
This monitor's aspect ratio means that many online videos, such as those from Netflix or YouTube, will have black spaces on the sides, which can be annoying.
Con HDMI connection is limited by 30Hz
Full resolution of 60Hz available via DisplayPort and HDMI also, but intel-based systems limit resolution to 30Hz while using HDMI.
Con To use the 4K gaming, high performance of your computer is required
That means, at least 16GB of RAM (system memory), it will never run out of RAM no matter what game you play; and 4GB of VRAM (video memory).
Con Lack of speakers
Con Heavyweight
Approximate weight of this monitor is 7.3 kg (2.1 kg - removable stand).
