Looks nice but: - Will your graphics card handle it? I have found that if you are sitting close to a large 28" screen it requires swivelling my head to see all over it. Your choice of course but I find my 22" screen large enough. Also the cost. Wow! $500 or £400+ just so you can get 4k resolution? Why not wait a year and you will get same monitor for £200.
