Our Verdict
AOC CQ27G1
AOC CQ27G2
The AOC CQ27G1 and the AOC CQ27G2 are nearly identical, and most of the differences we measured can be attributed to panel variance. The newer CQ27G2 uses a slightly different panel structure and has clearer text than the CQ27G1, and it has a slightly more aggressive curve (1500R vs. 1800R).
