Acer started taking orders for the first 4K HDR 144Hz G-Sync monitor last week, and now Taiwanese compatriot Asus has a product offering that same enticing combination of specs. The PG27UQ is another 27-inch IPS panel, and Asus says it's the first monitor to offer DisplayHDR 1000 certification, though Acer's Predator X27 also goes up to 1,000 nits.

Until now, PC owners have had to choose between resolution or refresh rate when picking a gaming monitor. (I myself picked the latter a while back when I bought Asus' 1440p 165Hz PG279Q, since the 4K equivalent only went up to 60Hz.) It's questionable how many people have rigs that are actually capable of pushing 4K resolution at super-high frame rates, and HDR support on PC is still extremely spotty, but bleeding-edge early adopters will be pleased that the ceiling for monitor performance has been raised.
