hi, i've searched everywhere for this issue but i can't seem to find a solution for it. I bought my u2414h monitor yesterday and it sometimes randomly switches off while i'm using it. i've tried resetting it, unplugging the cables but it still happens. there isn't a fixed pattern of the occurrence. its pretty annoying because it affects me when i'm gaming as I'd have to manually press the power button to turn it on again. Also, where do i find the service tag for the monitor? I want to register my warranty but I can't find the service tag.
details:
u2414h
custom built pc
windows 7
nvidia gtx760 (DVI, HDMI, DP)
using miniDP from monitor to DP in video card (using the cable that came with the monitor)
Thanks in advance.
