AOC U27B3A

This is a 27-inch IPS panel at 3840x2160, refreshing at 60Hz. Response time is rated 4ms. At 60Hz this targets productivity and cinematic gaming rather than esports. Its $189.99 price tag places it squarely in mid-range territory.

PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total. Warranty coverage follows AOC's standard policy — confirm regional terms on the listing. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked. The category page surfaces comparable models near the same price, which makes shortlisting against this monitor straightforward.
