This is a minor issue but i want to know if there is a solution. I have black borders up/down/left/right in bios/boot screen, but once i login to windows it goes fullscreen. Also this only happens when i connect the monitor witha dvi cable. my monitor is a lg w2361v-pf. I have tried the same monitor connected with dvi to another pc and everything is in fullscreen.
Any ideas?
Thank you
ps.I use the onboard gpu

This only happens because when booting the BIOS uses a different set of drivers(very limited) for the display and then as Windows loads the proper drivers take over. It is not a problem and I wouldn't lose any sleep over it.

You are right it's not such a big deal, it's just that it seems weird that a 478 socket mobo with gforce 5700 is doing it right but my 2010 mobo doesnt :/

any idea about how to solve that?

Hi,
as Dark Mantis has stated there isn't much that you can do although it is annoying. The basic video output that you are seeing on your screen is not controlled by standard drivers but by the very basic ones available though BIOS and might only be resolved with a different BIOS version. Although it is frustrating and it would be nicer to see BIOS as a full screen image it is more important that you can actually see everything, even if it is bordered by black stripes, as you describe rather than losing parts of the screen owing to screen size/resolution.
I'm sorry but I don't think there is anything that you will be able to do yourself to change the situation.

Yes, years ago you could set the BIOS option for the display but it seems to be something that went along with DOS.

I just cant understnand since you say it's a driver problem, why when i use a vga cable it is fullscreen. How the cable can interfere with bios?

Hi
In BIOS I believe the video output is only sent in analogue although you can see it through the DVI it is a limited image constrained by the BIOS. When you are using the full system resources this restriction does not apply.
The BIOS is a very small piece of code, about 8 Mb's on Gigabyte boards and an update re-writes approx 0.79 Mb of this code and this 8Mb's has to handle all of the basic in/out instructions that are needed to make your PC work. The drivers for most graphics cards are 10x this size and all they have to do is drive the GPU.
Analogue video uses less resources than digital, think about the difference between a DVD and movie film, it also needs less instructions to handle image scaling than Digital images and to write the necessary instructions to power ALL digital monitors as well as the Analogue ones would mean that something else would have to be dropped from the BIOS.
Whichever cable or adapter being used, the signal being sent is analogue not digital.
