You should normally see the kubuntu splash screen on an LMCE 810 install.
My Zotac ION doesn't show a splash or text during boot if I use the vga connector to my television but it does if I use the HDMI connector. I have not tested DVI but it should be the same as the HDMI. I would expect you should be able to see a splash screen, especially if you've got boot text scrolling.
You should try adding a vga=xxx line to the kernel boot options. Edit /boot/grub/menu.lst and find the '# defoptions ....' line and add 'vga=791' (for 1024x768x16, as an example) to the end of that line. Save the file and run 'update-grub' then try a reboot. Your television may or may not support that resolution (mine does) so you can always try others in that case: http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers
Running 'hwinfo --framebuffer' at the console should spit out a list of supported video modes on your system, these may or may not be supported by your television.
