BIOS bootup screen looks weird, help please

[steve2470]

I'm using a Gigabyte 990FXA-UD3 motherboard. Recently I could not access the BIOS, so I reflashed the BIOS. I can get into the BIOS now fine. However, the original problem has not gone away.

On my 24" Samsung monitor, the BIOS screen displays perfectly. I can read all the text with no problems. When I hook up my box to my Samsung TV (37&quot , then the BIOS screen is cut off on the left and right. When I first installed the motherboard I had no BIOS screen problems. I'm using the same video card (Nvidia GTX 560) that I was using originally. When I use the computer fully booted up, I have no video problems at all, which is why I'm so puzzled. I've gone into the BIOS and tweaked everything that makes sense. I'm not even going to try to do any overclocking lol

If it matters, I'm using a DVI to HDMI cable (DVI at video output on computer, HDMI input for the TV). I've never had this problem before about 2 weeks ago. I finally got annoyed enough that now I'm trying to fix it. Normally the BIOS screen displays perfectly on my TV, and I've been doing this for years.

Any help is appreciated. Thanks.

1. Hey, I've got the same board!

This is probably something to do with the tv scaling the low res output from the bios.

However, I'm not entirely sure why this would start all of a sudden.

Once the machine is booted, does everything display OK?

I've read that using VGA will allow the TV to handle the scaling and may help.

Something I would try would be to boot the machine, hop into the BIOS, then change the channel on the TV, then go back to the HDMI input, maybe the TV will re-adjust.

EDIT:

Are you doing any overclocking with the mainboard? I was able to hit 4.1 stable under water with my 1100t, dont ask about the voltage, haha!

Not doing any overclocking, I'm too afraid lol

eta: After doing some more reflashes, I think the BIOS is just flaky. I'll go to the Gigabyte forum to ask. Thanks all.

eta2: Did a reflash back to FC bios version, and plugged hdmi cable into a port labelled DVI on the back of the TV. Bios boot screen looks ok now. Ok, hope it stays that way.

3. Overclocking is cake!

If you ever decide to take the dive, I'd be happy to answer any questions.

I don't think it's your BIOS, if everything looks normal on different monitors.
