Hi,
I've got Dell ST2210 FullHD monitor connected via DVI (and DVI means not HDMI) to my GTS250 and I've noticed black border during bootup (POST screen, BIOS settings, GRUB2 bootloader, system splash screen etc). Once login system appears (with loaded graphic drivers), everything looks fine.
Strange things are:
* monitor shows me 1920x1080 60 Hz mode
* GRUB2 bootloader background looks like ~1920x1080 (and not 800x600 stretched) as I've managed background saving it as 1920x1080,
* borders differ a bit - they are not in the same places (for example POST borders are a bit smaller - 1 or 2 mm each size - than GRUB2 bootloader background)
* on my previous Samsung 1680x1050 everything was fine - POST and BIOS screens was stretched properly.
Is it anything I can do with it ? It's annoying to have black borders at FullHD monitor. And basic question: is it monitor fault (like scalling), or graphic card VBE wrong implementation ?
Any clues welcome,
Thank you in advance

Well I can't profess to be an expert on monitors but the BIOS screens have always been at a lower resolution than the OS. For obvious reasons they are limited in size and colour depth. Whilst it is possiblew for a monitor to stretch them to appear to be full screen this depends on the display. I would say that your problem is caused by the size of your display and it may be possible to extend the picture by settings on the monitor.
Just my thoughts on it but hopefully may help.

You are able to customise your bios splash screen. I have a image of my two kids that comes up at home. But I suspect you are meaning the actual bios screen itself. Since I can not find what motherboard you are using I am unable to check and see what the default setting is. But I do suspect it is 4:3 based which would explain why it worked on your previous monitor. But I am guessing as I said.

No, that thing what you describe is stretching smaller display size to nominal LCD resolution. In my Dell this option is called "Wide mode" and is set to "Fill" by default.
I've asked the same question at Dell forums and will see who's gonna to confirm first that is "known" issue of its brand ;-) So far Dell's admin deleted my post once, huh.. and what about BIOS emulator in GB graphic card, is it true that VBE doesn't support FullHD resolution, just 1600x1200 ? :) Maybe it's possible to change some values using Nibitor then ?
P.S.
My mobo is Asus Striker II Extreme, but even if I customised somehow PC's BIOS (to avoid borders during POST & BIOS settings), how to customise my OS' bootsplash & GRUB2 background, which is set to 1920x1080 and looks like FullHD, but a bit downscalled + borders added ? BTW, 1680x1050 is 16:10, not 4:3-based.

Yeah I hear you but since I do not have a Dell monitor to test this out with I am stuck at the moment. Oh you could send me yours of course. ;D ;D
As to he 4:3 I am referring to the bios image used not the monitor. Sorry for being unclear.
Let us know what if any response you get from the DELL forum please.

Before they deleted the whole thread, one answer appeared and it referred to HDMI connection (which is usual problem as I've read), but I underlined that I didn't use HDMI but DVI, so the thread dissapeared :-/
I could bet if I was able to do some changes in graphic card (which I don't know if they - specific ones responsible for signal details - are editable via Nibitor), it would be solved, in my opinion. On the other hand, patch applied to monitor firmware should eliminate this issue, too, but I have no tools to reprogramming LCD ;-)
