Performs well, but.

Upon opening the box, I found a brief set of instructions included in the box, along with a CD for the drivers. The instructions never made it clear when or how to install the card and the drivers, so it was trial and error. The drivers need to be installed first, power down the PC, install the card, and boot up. The box has a requirement of a 400 Watt power supply posted, but nowhere else in the specifications or instructions. Mine appears to be working as expected with a 250 Watt power supply. The instructions packed with the box may have been incorrect, as it shows a power harness connecting directly to the card. There's no receptacle on my card for a power connector. This card was purchased mainly to make my HP tower PC compatible with my Ultra HD 43" LG monitor. While 4K videos produce breathtaking results, with no apparent digital artifacting, I can't find a monitor or adapter setting that doesn't over-scan the screen by about 1/2" in all directions. So I really can't give this product five stars, without knowing why the over scan, and the poor in box instructions don't provide much help.Read full review
