Hey guys,

I'm hoping someone can help me with a very annoying problem I am facing. I just upgraded my graphics card to an MSI Radeon R9 280x 3G Gaming Edition card. The problem I'm having is that during post I get a distorted, almost out of range muddle image which does not allow me to see the BIOS or UEFI. If I leave the computer to boot the windows starts up fine and the display is normal. It is only during the POST that there is no display. The TV I am using is a Panasonic GT50 plasma and upon booting my TV tells me that the refresh rate detects a 1080p 50hz input however, there is no display. Of course my TV supports this resolution as it is standard PAL.

I've been looking on the net and found only a handful of people with a similar issue but I haven't found a solution as yet. I'm guessing it's my TV as the BIOS/UEFI displays fine when I connect my TV to another set. I have absolutely no idea how to fix this and I'd appreciate some suggestions. I'll try uploading a video of the problem if that helps. Thank you in advance for your suggestions!
 
It's a UEFI/50hz tv issue that that affects both Ati cards and Intel on gpu graphics. Nvidia's card's seem to be able to get around this problem.

If you hook up a 60hz monitor that will allow you to see the post screen and enter the bios.

Setting the motherboard bios to "CSM only" allows me to use the intel on gpu to display the bios/post screen correctly through vga using a hdmi to vga converter.

In "CSM never" mode the motherboard is completely in UEFI so graphics card bios needs to be set as uefi never and ssd formatted for UEFI. The Ati card produces a squashed bios screen/post screen in this mode through hdmi.

Can I ask are you using a HDMI cable ?

The drivers for this are not loaded until Windows starts up.

This works well but if you feel the need to enter the BIOS you will need to connect a VGA or
a DVI-d cable. Then set the TV to PC.

There is no other way than connecting apart from using hdmi as the OP's plasma does not have dvi or vga input's.

You can connect through hdmi to dvi cable but that only produces the same result's.

It's not that hdmi drivers are not loaded before windows as nvidia cards get around this problem, it's more a UEFI/50hz issue with Ati and Intel cards.

Thanks guys. I don't think there is a way around this problem which renders the card pretty much useless. I will try the BIOS switch to see if by some miracle it works. Win 8 .1 is spot on. DVI is not an option for me. Cheers for the help guys!
 
As I have a Panasonic plasma and as Ati card as well my workaround is either to use the onboard gpu through hdmi to vga converter or connect a 60hz monitor if on occasions I need to access the bios.

You need the BIOS often? If it works in Windows I don't see the card as useless.
 
pretty sure I could access the bios fine with my 7850 and Samsung tv through hdmi

could depend on tv model though

Not too often once I get the PC set up the way I want it, but I'm trying to make some clocking tweaks here and there which is a bit of a pain. My onboard HDMI is an option but it doesn't actually work. I'm thinking it could be disabled in the BIOS or something as I've never used it. Now; how do I see the BIOS to change it :D

By hooking up a 60hz monitor changing it and switching back to the tv.

Only works if you have a spare 60hz monitor though. :)

Worst case scenario, I'll shift the unit back into my kitchen TV and change it from there. It isn't exactly portable though. Oh well! ;)

A cheap 60hz monitor that you could connect anytime you needed to access the bios might save all the hassle. :) That or a cheap low power nvidia card with UEFI bios that you could fit in a spare pci-e slot and switch to if needed.

if you keep pressing delete or F2 then would it boot to bios?

That's a good point mightymouse. I did try that once but it didn't wor for whatever reason. I will give it a try again some time tomorrow incase I was pressing the button at the wrong time or something. Cheers!
