Add additional display resolutions #1

Open EndlessDelirium opened 7 years ago

EndlessDelirium commented 7 years ago

Currently the display resolution seems to be fixed to 1280x800px on Pine64. It would be awesome if the most popular resolutions could be supported by this BSP.

Set Display Resolution and Orientation

Your device only supports one display resolution
I can't change the existing device resolution settings

We haven't built a display adapter in Windows system. Instead, the display output is supported in UEFI , so the resolution is unmodifiable in Windows. If you want to change the resolution, you can rebuild a UEFI with a new resolution in sysconfig. Refer to this repo for more information about UEFI https://github.com/Leeway213/WinIoTBoot

The config file is ./edk2/SunxiPlatform/pack/chips/[chip id]/config/pine64/sys_config.fex. Find HDMI configuration and modify it.

Thanks for the speedy reply. The unmodified sys_config.fex looks like being configured for the Pine64 MIPI DSI attached 7" touchpanel? That however doesn't work at my end.

Furthermore I couldn't figure out how to change the HDMI resolution to 1024 x 600.

;screenx_output_mode (used for hdmi output, 0:480i 1:576i 2:480p 3:576p 4:720p50) ; (5:720p60 6:1080i50 7:1080i60 8:1080p24 9:1080p50 10:1080p60)

Is it possible to somehow configure a resolution that isn't mentioned in that list?

About the MIPI DSI issue, need different adapters for different screen model because of their different specification. This BSP is not an all-round software indeed. And actually we are working for the display engine on Windows right now. We will support some common screen model, and also we can open a SDK for different screen model to adapt.
