dell did a full warranty on the older model xps 13. I got the one with the infinity-edge . only problem is when I go to play acutal 4k videos i get really choppy playback. Im on the highest power profile I can get and also have installed the latest windows 8 drivers for video. I got this from work so I really cant take it back. I mean I can deal with 1080 and 1440 but 4k is so nice. Has anyone fixed this issue before? Edit: here are the stats as follows: 13.3-inch QHD+ infinity touchscreen Intel Core i7-5500U 8GB memory/256GB SSD Windows 8.1 latest drivers from Dell as the automatic intel driver update cant seem to find any.
