We compared all the other PC monitors with a built-in speaker(s) to this LCD screen and we think because of it's better review score, the AOC Q3277PQU, and the Asus MG278Q ($508.99) is also worth considering.

It is worth also looking at alternative PC displays which also have a built-in speaker(s) including the Acer H277HU.
