Somewhat out of the blue, my P2415Q arrived today. I've only been using it for a few hours this afternoon, but so far I am deeply impressed. Windows 8.1 DPI scaling isn't perfect, but it's working quite nicely for me, and gaming is incredible. I am amazed at how good Skyrim looks at 3840 * 2160, even with the settings scaled back to enable my single GTX 970 to maintain an acceptable frame rate. Dishonoured looks wonderful, too. Hopefully the GTX 970 will hold up to the other games I have lined up![]()

It does come pre-calibrated with a report document, though I have to confess, I didn't look at it. Unfortunately I don't know anything about testing for input lag and response times, so I don't understand how to use the site you linked to - PCM2 will probably be able to provide a much greater insight.Can you comment on input lag please and check response times on various colour backgrounds with different overdrive settings here

Many thanks. Does it come pre calibrated with a report document?

For my part, I have not noticed any problems, but all I have to compare it to are the Dell U2212HM it replaced, and the ancient Hazro HZ30W I use with my other PC. Sorry for the vague, subjective responses, I suspect that they will not be of much use to you :|
Just FYI, total input lag is just under 12ms according to my testing. This includes an element of pixel response time and indicates quite a low signal delay. The pixel responsiveness is actually better and more consistent than on the 28" TN panels as well. It isn't hampered by some noticeably sluggish transitions in the same way. Overall I feel this is a good choice for 4K gaming if you don't want a large screen.
@ PCM2
Just a thought. Is the low lag figure in standard or the game preset like various other Dell monitors?
