TFT monitor not displaying boot set up when selected

By TOG182 ·
I have a Vusys TFT monitor that does not display the boot set up screen for my desktop running Windows XP or the recovery console for my other desktop running Ubuntu 9.10.

The monitor displays OK once the operating systems have loaded.

Both these computers use the same monitor (mentioned above) through a KVM switch.

I connected the monitor directly to the Windows XP computer and it still did not show the boot set up screen.

Would I be right in thinking the problem actually lies with the monitor, rather than the computers.

Maybe. Here it depends on the actual computer if it has On Board Graphics and a Plug in Video Card.

If it has On Board Graphics you may need to enter the BIOS and disable it or if that doesn't work plug the monitor into the On Boards Video Outlet.

Then assuming that the Monitor is warm before you turn on the computer and you have more than 1 Video Out on your Video Card you may need to move this monitor to the other Video Output as it could be connected to the Second Video Output. Depending on the Video Card this may not be active till Windows has loaded and it's drivers are installed.

If this monitor has a DVI Plug on it and your Video Card has both SVGA and DVI you may need to use a SVGA to DVI Adapter if you want to view the POST Screen and Boot Loader.

Finally this monitor may require any special drivers for it to be loaded before it displays a picture, though not a common issue I have seen this before with some of the earlier Flat Screen Monitors.

The thing is there are 2 computers using the same monitor via a KVM switch.

One computer is running Windows XP SP3 with a Geforce 5300 graphics card (on board gaphics disabled).

The other computer is running Ubuntu 9.10, with onboard graphics card.

Both outputs are SVGA (though the Geforce has a DVI output).

The problem is that when boot set up is selected on the XP machine & when recovery option is selected on the Ubuntu machine the screen goes blank.

I have tried connecting the XP machine directly to the monitor and the same thing happens when the boot set up is selected.

As it is both machines I thought the common factor was the monitor.

Forgot to mention the monitor display is OK once past the boot up sequence, on both machines.

It is only the boot set up (on the XP machine) and the recovery option (on the Ubuntu machine)when the screen goes blank.

I'm understanding your question differently than OH Smeg.

You don't say that you don't see a picture after booting, just not being able to see the "boot set up screen." <br>
I've seen in a computers BIOS where there's the option to turn off the "boot setup screen" by which I think you mean the BIOS setup. You have to enter the BIOS and turn that option back on. You can't see what key to press to enter the BIOS because the option is disabled.<br>
You can press a key while booting to enter the BIOS but the key to press varies by the BIOS manufacturer, mine is the Home key. You can often look up the manual online for your computer by brand and model or look up the motherboard manufacturers manual. A manual should tell you what key to press.<br>
I'd give you a list of the most common keys to press to enter the BIOS but my brain refuses to divulge that information right now. <br>

If I've misunderstood your question feel free to completely ignore me.
