Hello. NXP

 

My Board : i.MX 8M Quad Evaluation Kit

My OS : windows 10 iot

 Using MCIMX8M-EVK Image FFU File,

When connected to a monitor that supports 3840x2160 resolution using the native HDMI port, it displays at 1280x720 resolution.

  

How to change to 3840x2160 Display Resolution?

Hello Sunjib

Windows 10 IOT display driver for 64bit (imx8MQ included) doesn't support change display resolution yet. HDMI initialization (display) is performed in u-boot code (see imx8mq_evk.c file), display resolution is configured to the fix value 1280x720 60Hz. You can modify  imx8mq_evk.c file in u-boot and HdLcdiMX8.c file in UEFI (mu_platform_nxp) on you own and rebuild u-boot & UEFI.

We plan to support of display resolution change in Windows 10 IOT display driver in future.

Best Regards
