LG Ultra Gear is great Monitor
I recently bought an LG Ultra gear Monitor from PB Tech and it is a joy to game with. Beautiful display and great contrast helps immerse me in whatever world I choose to roam. 100% Recommend.
Just awesome!
Bought this as an upgrade from a 1080p monitor, and I am not disappointed. It comes with an adjustable monitor stand, which is very helpful. The built-in USB-C port for charging and data transfer is a game-changer. It has a built-in speaker as well, but I still prefer using my old pc speakers. All in all, I am delighted to have chosen this monitor.
Easy to set up & Brilliant picture
This QHD monitor provides a very bright and clear screenm, comparing FHD one. I am satisfied with this LG UltraGear 27" monitor.
Highly Recommend
One of the best monitor
Highly recommended
Perfect match with my existing 27-inch 4K 60Hz monitor—didn’t expect the visuals to be this smooth and vibrant! Highly recommended. My viewing distance is about 70 cm, and honestly, I can hardly tell any difference in sharpness compared to 4K.
