Among 4k gaming monitors running faster than 60 Hz, the Viotek GFI27QXA is a decent value. Only a handful of UHD screens run at the 120 or 144 Hz level, and they all cost more than the Viotek.
But there are some caveats to consider. If you want FreeSync or G-Sync, 120 Hz is the practical limit. And you won’t be able to use HDR with Adaptive-Sync at any refresh rate. This isn’t a huge loss because we didn’t find much impact from HDR in the games we played. HDR mode did enhance the look of 4K HD Blu-rays, however, so the feature has some merit.
For less money, one could choose from QHD monitors like the Asus ROG Strix XG279Q or ViewSonic Elite XG270QC. They both deliver good HDR alongside Adaptive-Sync at high refresh rates. If you’d rather pair solid gaming performance with HDR, one of the QHD screens is a better and less-expensive choice.
But the GFI27QXA can claim one important victory: color volume. It covers 100% of the DCI-P3 gamut with accuracy. Other positives include its build quality and solid gaming performance at 120 Hz.
If you want a 4K monitor for your gaming rig, the Viotek GFI27QXA is a good solution at a reasonable price.
