Frequently Asked Questions
01 What type of panel does the Benq EX321UX use? ›
It features an IPS panel, which delivers wide 178° viewing angles and consistent colour accuracy. Colours stay accurate whether you're sitting centred or off to the side.
02 Can the Benq EX321UX handle gaming? ›
✓ Yes — the 144Hz refresh rate makes fast-paced titles noticeably smoother than 60Hz. Fast camera pans and character movement stay sharp. 1ms response time minimises ghosting. FreeSync Premium Pro support prevents tearing without V-Sync input lag.
03 Is the HDR 1000 certification worth it on this monitor? ›
HDR1000 delivers genuine highlights — sun glints, fire, and neon signs visibly exceed what SDR can show. Streaming HDR content on Netflix or playing HDR games produces a noticeably different result compared to HDR400 or SDR panels.
04 Is the Benq EX321UX suitable for photo or video editing? ›
✓ Yes — 99% DCI-P3 coverage means the colours you grade in Lightroom or DaVinci Resolve stay consistent when exported to screen and print. Suitable for professional colour work without a dedicated calibration monitor.
05 Who is the Benq EX321UX best for? ›
It is best suited for gamers, content creators. Check the "Who Should Buy" section above for a full profile breakdown.
06 Does the IPS panel cause issues in dark rooms? ›
IPS panels produce a slight glow in very dark rooms when displaying black content — this is normal for the technology. It is most noticeable in pitch-black rooms. For dark-room cinematic use, a VA or OLED panel would produce deeper blacks. For everyday and office use it is not an issue.
07 Is the Benq EX321UX worth buying in 2026? ›
Benq EX321UX remains a strong option in 2026. 144Hz refresh keeps motion smooth for gaming, which remains relevant as 144Hz+ is now the expected baseline. Wide colour gamut coverage remains relevant for photo, video, and content creation workflows. Our benchmark score of 8.4/10 puts it in the top tier of its category. Before purchasing, compare the current street price against newer models at the same price point to confirm it offers the best value for your use case.
