LG 42.5" 4K IPS Monitor

I found this monitor on sale for $800 CAN and it is tempting. Staples has a 30 return policy.

Anyone out there have a issues with their 4K monitor set up.

Main reason i want this monitor is to have a bigger work space (especially a slightly bigger video review panel) for colour grading.

Any advice is welcome.

I use a 32" 2160 monitor. I think I would find 42" too big for my desk, but if you don't...go for it!
