TechSpot takes a look at the Acer Predator X27
A quote from the article:
The Acer Predator X27 is an impressive 4K 144 Hz gaming monitor with DisplayHDR 1000 and, of course, G-Sync HDR. It's a direct competitor to Asus top-of-the-line ROG monitor, but Acer's is better looking and better built for the same monstrous price tag.Acer Predator X27 Review
