AMD RADEON 5450 - Issues with using multiple monitors

therealhyper · 23 Aug 2015

Hi,

I have a HP Pavillion Slimline -S5311 running OS Windows 7 (Home Premium).

I had a single Monitor connected via the standard VGA Connection (VGA to VGA) which was working OK.

I installed a AMD RADEON 5450 card to try and use multiple monitors.

This allowed me to connect 2 Montiors:

Monitor 1 = DCI (AMD Radeon 540 Card) to VGA
Monitor 2 = VGA (Original PC Connection) to VGA

This was working OK, but recently the Monitor 2 (VGA to VGA) stopped working.

I have tried to trouble shoot this issue including changing cables and monitors but can not get 2 monitors working at the same time.

I found the VGA connection will now only work if I disconnect the AMD RADEON Card.
When I use the AMD Radeon Card, the VGA Connectionn will not work.

Has the Radeon Card burned out (approx 10 months old).

Also, I have tried to use the HDMI port from the AMD Radeon Card (HDMI to VGA) but this does not work either..I am assuming I will need a HDMI to DCI cable ?

Thanks

I can't get the manual for your PC from HP, but there may be a setting in the BIOS that has changed. If that PC allows you to use the onboard graphics at the same time as a graphics card, there would probably be a setting in BIOS that allows you to do so. Check your graphics settings in BIOS to see if there is such a setting.

On the other hand, the 5450 would probably be able to run two monitors simultaneously off of the one card. Just use the VGA connection on the card, and the DVI connection on the card. You'll likely get better quality on the monitors if you do that. If your monitor doesn't have a DVI connection, you can always use a DVI to VGA adapter and use a VGA cable if that is what you have.

The 5450 is not exactly a high end card, but it still should be able to run two monitors simultaneously without problems.
