Boot time screen resolution

[osmcb]

This discussion suggests that it should be possible.

Resolution of the boot image

No, I don’t believe so. It seems that U-Boot believes the preferred video mode of your device is 720p50. It would be good if you could run the following commands to confirm whether the kernel also believes this: cat /sys/class/amhdmitx/amhdmitx0/edid cat /sys/class/amhdmitx/amhdmitx0/disp_cap If you have an AVR, you may wish to connect directly to the TV temporarily. It’s possible it’s giving the device the incorrect EDID. Sam

Resolution of the boot image

There should be an asterisk beside one of the modes on the output of the second command next to the TV’s preferred mode. Your TV is not reporting a native/preferred mode. Because of this we default to 720p. This doesn’t stop you selecting 1080p in Kodi however, so it only affects the resolution of the boot screen. The program that displays the boot screen does not do high quality scaling so any boot resolution besides 1080p will cause the word OSMC to look a bit jaggy.
