splash screen requires that terminal output is set to gfxterm

insmod gfxterm
terminal_output gfxterm

before loading gfxterm you may set preferred mode with

set gfxmode=xxxx

(see manual)

Hello Andrei, Thanks a lot for your response.

In the grub shell I typed the following commands:
   insmod png
   insmod gfxterm
   set gfxmode=1920x1080
   terminal_output gfxterm
I see and error at this point: "no suitable video mode found"

I also tried setting gfxpayload to 'keep', but did not help.

I did read the manual (partially)  but did not find anything on how to set the video mode. Sorry if I overlooked some portion. If you have any more suggestions it would be of great help.

Regards, Pj
