Windows 7: UEFI BIOS split/offset on HDMI output?

UEFI BIOS split/offset on HDMI output?

This is my first time encountering such a strange issue, I don't really know how to describe it and googling doesn't really turn up much either (most just say auto-adjust display but this is a HDTV) so here's a pic.

MSI Z68A-G43 (G3)
i5-3570K (not overclocked)
Powercolor HD7850 PCS+ 2GB

In fact, I connected the small screen just so that I can read things in the BIOS properly. It's connected via MiniDP > VGA.

Tried connecting the TV using:
HDMI direct
DVI-D > HDMI adapter
MiniDP > HDMI adapter
Also tried 16:9 overscan on/off, it only makes the image bigger/smaller.

All the same. TV got no VGA input to test, not that I'd want a VGA connection anyway, for quality reasons.

The issue persists from boot up through post and Windows logo loading screen. Windows login screen onwards, all is well. I have updated with the latest 15.4 Catalyst drivers. Chipset drivers are also current. The issue does not appear when using onboard video.

Does anyone know what's going on please?

I am not familiar with UEFI BIOS, maybe an option for display resolution? Seems you get this with standard VGA and it corrects when drivers are actually loaded.

Does TV have display modes? For example mine has: Auto fill/ Auto zoom/ Super zoom/ Movie expand 16:9/ Wide screen/ Unscaled

UEFI BIOS (or any BIOS that I know of) does not have resolution settings. I only have 16:9 overscan and Aspect Ratio settings. The latter only works on 16:9 settings. If I set it to "just scan" it makes the image smaller and blurry.

Is the Dell Vostro 400 (my computer) and Toshiba T135 (my laptop) legacy BIOS or UEFI? Note: I have not yet updated the BIOS because I'm too lazy to do so and because it is not required.
