I've started using a Technika LCD TV with my PC and, while it displays full OS graphics, the text that is usually displayed during boot up (with the exception of the initial BIOS screen) does not show - the screen goes blank. I can sometimes see text for a brief fraction of a second before it disappears from the screen.
The TV's on-screen display menu will also not show during times when the text does not show but it occasionally shows a "No signal" message. The OSD menu will display again as soon as the OS graphics appears.
The main problem this causes me is when I test a new graphics driver in Ubuntu and it fails I cannot see any text on the screen to type command line instructions.
Another situation that involved a blank screen output was while playing a 3D game in full screen. I changed the game resolution mid-game and the screen went blank.
Please clarify why this problem is happening and tell me how I can use the console when the Linux graphics driver fails to load. Thanks.
UPDATE I am pretty sure it is to do with my HDTV not supporting the resolutions being used in each blanks screen scenario. Can this be fixed in Grub? See Reducing video mode switching during Linux boot. I am unsure about Grub and its settings.)
Technical info: Nvidia GeForce 9600 graphics adapter connected to a Technika LCD 32" TV via a VGA cable connected to a DVI adapter/port on the computer. My working resolution in Ubuntu is 1360x768 but according to the TV's OSD menu the TV is operating at 1280x768 resolution.
