Happy with my old model one after 6 months odd. Running it at 30Hz is really not such a problem for coding, office work etc. Video even plays well enough for the most part.

Running off Intel HD 3000 (i7 2640M) works OK. Occasionally you see it struggle with all the pixels but on Windows 7 and now 10 it's perfectly usable.

Use a decent DisplayPort cable. I found one reasonable looking quality one gave a number of issues when hot plugging. Reverting to a Philips supplied one and the problem went away. I have a new XPS13 that can do UHD at 60Hz via USB-C and that occasionally blanks out - could be the USB-C adapter but it was a pricey one so hopefully not.

No issues with "burn in" like one of those Amazon reviews complains about on the new model.
