Q: Why the HDR function seems not working when it’s enabled?

A: Please check the list of recommendation below before you enable the HDR function:

• Ensure your GPU supports PlayReady 3.0 and 10-bit decoding capabilities. DisplayPort 1.4 is one of the best display connection options. If it isn’t available, HDMI 2.0 or USB-C Thunderbolt connections is the alternative.
• Ensure your GPU driver version is compatible with HDR10. We recommend drivers such as NVIDIA GameReady 446.12 (Windows 10 v1909 and earlier  versions), 451.48 (Windows 10 v2004 and later version), or AMD Radeon Software Adrenalin 2019 Edition 12.12.1 and later version.
• Ensure your Window version is compatible. We recommend Windows 10 64-bit v.1809 and later version.
• Ensure your internet browser is compatible and HDR option is selected. (Due to the current technical limitation of Chromium-based browsers such as Microsoft Edge on Chromium and Google Chrome do not officially support HDR playback. Upcoming updates are planned to add HDR support to these browsers. A workaround is to use Microsoft Edge UWP browser installed by default with Windows 10.)
• Ensure necessary video codecs are with hardware acceleration capability such as “HEVC Video Extensions” or “VP9 Video Extensions” is installed for optimum viewing experience. It can be found on Microsoft Store.

Q: Why I have strobing flicker on my screen when I turn on MPRT mode?

A:

• MPRT is one of the strobe backlight techniques which make panel display flicker to improve the perceived motion clarity for gaming.
• MPRT mode is only recommended to enable for gaming as it may cause a deliberate strobing flicker to the display which is not for normal office-type uses. You can refer to the article from TFT Central for more detail about MPRT: https://www.tftcentral.co.uk/blog/why-moving-picture-response-time-mprt-specs-can-be-misleading-and-where-1ms-mprt-is-sometimes-abused/
• We recommend the “Fast” setting of Response Time Override in conjunction with MPRT mode which provides the best setting to be a comfortable brightness for a start.
