Frequently Asked Questions

What is Dual QHD resolution?
Dual QHD (DQHD) is 5120 x 1440 resolution, which is essentially two QHD (2560×1440) monitors side by side. This provides an incredibly wide, detailed canvas for immersive gaming and productivity, equivalent to having two 27″ QHD monitors without the bezel in the middle.
Is this the best monitor for golf simulators?
For monitor-based golf simulator setups (as opposed to projector setups), this is one of the most immersive options available. The 32:9 aspect ratio and massive 45″ size provide a panoramic view that wraps around your peripheral vision, delivering an unmatched sense of immersion on virtual courses.
What graphics card do I need?
Given the high 5120×1440 resolution and 165Hz refresh rate, we recommend a mid-to-high-end graphics card such as an NVIDIA RTX 3070 or better, or AMD RX 6800 or better, to get the most out of this display in demanding games and simulators.
