Display problems.

Hello.

Two monitors are connected to the two DVI connectors on the graphics card. The motherboard also has onboard graphics, which is set to 'Auto'. The monitors automatically use the graphics card for video.

If I disconnect both monitors from the graphics card and leave the onboard option to 'Auto' (and connect one of the monitors to the onboard DVI graphics connector) , the monitor does not come on at all and goes on stand-by.

If I want to try the onboard graphics, do I need to to change the option from 'Auto' to onboard? If yes, and the monitor still does not come on, if I connect the monitors to the graphics card again, will they work again automatically even though BIOS has now been changed to use onboard graphics or will my computer be stuck without video with no way to change the setting back to 'Auto' as there is no display?

Thank you.

Thank you for your reply.

Both the motherboard and CPU are old! The motherboard definitely has onboard graphics. Not sure about the CPU but it's about 15 years old!

As the title says, I am having display problems. It is possible that it may be the graphics card that's failing, so I want to use the onboard graphics. I don't need anything fancy for graphics, so onboard graphics would suffice. The graphics card was mainly to run my dual monitors. One monitor will do for now.

Thank you for your advice. I will try setting it to onboard. If I don't post back with an update, that means everything has gone wrong! Haha.

I set the motherboard to DVI, but the monitor still did not come on. Do I need to take the graphics card out entirely for this to work?

When I connected the monitor back to the graphics card, the monitor came on and worked even though the BIOS setting has been set to onboard DVI.

Thank you for your replies.

I do apologise, I normally include system specs, but I just thought it was a generic query and might not require additional specifics.

Motherboard
CPU
Graphics Card
Monitors
OS - Linux
No idea if motherboard graphics driver is installed.

Makes sense but the title on its own is rather vague.

I deliberately omitted additional info as I just wanted to know how to get the onboard to work and not concentrate on trying to fix the issue with the graphics card.

Just for your information, the issue is flickering and taking several minutes for the monitors to show anything. Initial startup showed fine, but not login screen, however, now even the initial startup doesn't show at times. Anyway, as mentioned, this post is about getting the onboard to work, not trying to fix the issue with the graphics card.

Thank you.
