What reviewers say

Reviewers agree it is among the best gaming monitors available, praising the very sharp 5K2K picture, accurate colour, good brightness and smooth, low-lag gaming. The common caveats are the high price and the powerful graphics card needed at native resolution; Tom's Hardware found gamma slightly light, and Club386 noted some uniformity issues and high power draw.
