ViewSonic will soon release a new 4K HDR high refresh rate monitor. The ViewSonic XG275D-4K features a 27-inch IPS panel with dual-Hz functionality, allowing you to switch between 4K (3840 x 2160 pixels) at a maximum of 160 Hz and Full HD (1920 x 1080 pixels) at up to 320 Hz. This means you always have the choice between image quality and frame rate/input lag optimization.

The ViewSonic XG275D-4K also boasts 10-bit color depth (8-bit + FRC), 300 cd/m² typical brightness, 1000:1 contrast, and 99 percent sRGB. FreeSync Premium and G-Sync-compatible Adaptive Sync ensure tear-free gaming.
Two internal speakers, each with only 2 watts, were also included. For connectivity, the monitor includes two HDMI 2.1 inputs, one DisplayPort 1.4 (DSC), a headphone output, and a USB-C port with DisplayPort Alternate Mode and 65 watts of Power Delivery. Additionally, 4K at 160Hz (or Full HD at 320Hz) should be possible across all graphic interfaces.
In terms of ergonomics, nothing is left to be desired, as the monitor offers tilt, swivel, height adjustment (130 mm), pivot, and a VESA mount (75 x 75 mm). Additionally, it features blue light filtering and flicker-free backlighting for enhanced comfort. Moreover, the 4K HDR high refresh rate monitor weighs 4.4 kg without the stand and consumes between 32 and 38 watts in Eco mode.
