I would like to know if it is possible to change the HDMI resolution on the SHIELD Tablet, preferably to 3840 x2160?
I tried to rebuild from source and adding CONFIG_TEGRA_HDMI_PRIMARY to kernel’s config file. This did not helped, in fact, nothing was being displayed on both the tablet and TV.
Few other things were changed: buffer size allocation, max pixel clock, frame buffer resolution. Did not help.
Has anyone done that? Any pointers would be appreciated.
