I bought this monitor and plugged it in straight away, the DP was a great addition. it worked perfectly for a while and then all my games started to lag, I thought it was my computer so I switched it out with my old monitor and that worked fine, my theory was the monitor was too intensive on my computer. the colours on the monitor are also quite poor but it would've been 3 stars if my computer could use it, just don't use it on an old PC
