TFT monitor DVI : no posting of starting when booting (no signal)
Hello,
I changed my old CRT monitor for a TFT one (Mirai). When I use the VGA connection, I can see all the starting sequence : post, lilo, launch of kubuntu (GNU/linux). But if I use the DVI connection, the monitor doesn't receive any signal untill the desktop starts. In this case, I can't access bios or the boot-loader, I don't see if the OS is starting correctly or not... I use an ATI Radeon 7500 graphics board with free drivers. My motherboard is Liteon NA380. Do you know what could I do ? Thanks for help Gary |

I'd replace it with something else, and probably nVidia based as the driver support tends to be better. |

Or that monitor cant handle the other modes on the DVI, like with the bios screen or that card isnt putting them out on the DVI connector for some reason. The obvious thing to try is a different monitor and see if it shows anything on the DVI input when the system is on the bios screen. |
