Alongside the recently showcased VX25G26-4, ViewSonic has revealed the VX2766-2K-PRO-4. It's a 27-inch Fast IPS gaming monitor with a native 400 Hz refresh rate and a listed overclock to 425 Hz at 2560×1440 - great for high-frame-rate QHD gaming. Specified for the display are a 1 ms GtG response, 450 nits typical brightness, and 1000:1 static contrast, with 10‑bit color achieved via frame rate control (FRC) color shifting on a native 8‑bit panel, and with gamut claims of 100% sRGB, 97% Adobe RGB, and 97% DCI‑P3.
The monitor includes AMD FreeSync and Nvidia G‑Sync compatible variable refresh support, along with HDR10 signal handling within SDR-class brightness limits. Connectivity on current materials lists two HDMI 2.1 ports, one DisplayPort 1.4 input, and a 3.5 mm headphone jack; the stand is tilt‑only, and the design uses a slim three‑sided bezel.
Operational details cite a matte anti‑glare finish and ViewSonic gaming features such as low blue light, flicker‑free operation, and preset color modes, which matches the brand’s recent esports‑oriented releases. Availability and pricing were not specified in the initial announcement, and regional rollout, including markets outside China, has not been listed.
If we look at the past models within the series, it shows a steady escalation in refresh rates across the PRO and 2K-PRO families. The VX2758A-2K-PRO-2 offered QHD at 180 Hz, followed by the VX2758A-2K-PRO-3 at 240 Hz, both with IPS panels, 1ms MPRT, and FreeSync/G‑Sync compatibility; the new VX2766-2K-PRO-4 advances to 400/425 Hz at the same QHD resolution. These predecessors also used tilt-centric stands and HDMI/DisplayPort connectivity.
