Installation of When I fit card I get blank monitor screen. Is there a conflict with onboard graphics?The motherboard is HP MS-6575 v3.1Peter Wiggins

Try fitting a working graphics card, this will remove the onboard graphics chip form the possible causes.

make the changes to the bios before you put the card in and also install the drivers to your operating system then turn off pc fit card and let me know if it works

hook monitor cable back to your onboard video port then 1st make sure you have already downloaded the driver for your new graphics card. then at start up go into system setup and go to your display and make sure that you have your new graphics card enabled as your primary graphics instead of onboard video. it will say something like 1.Onboard 2. AGP/OR PCI MAKE SURE YOU DONT HAVE YOUR ONBOARD ENABLED AS YOUR PRIMARY VIDEO. AFTER THAT JUST SAVE AND EXIT THE JUST HOLD POWER BUTTON DOWN TILL PC SHUTS DOWN THEN SWITCH YOUR CABLE MONITOR CABLE FROM THE ONBOARD TO THE AGP/PCI CARD THEN RESTART YOUR PC. THEN YOUR PC WILL SAY FOUND NEW DATA AND WILL INSTALL THE DRIVER YOU HAVE DOWNLOADED FOR IT THEN YOU SHOULD BE OK IF THE CARD IS COMPATIBLE WITH THE MOTHERBOARD

Your new Foxconn motherboard Primary Graphics Adapter settings in set to onboard vga that is why there is no display in your monitor. Do not install yet your agp video card. Use first the onboard vga of the motherboard.
Power up your computer and go to the BIOS settings. Locate in bios about the Primary Graphics Adapter settings and then select AGP. Save changes and the exit. Turn off your computer and now install the agp video card.

Hello

In that way no need to change the BIOS settings, you can install a new graphics card directly. Once you are already installed the new graphics card you need to install also the driver so that it will work properly. Connect your monitor cord to the new installed graphics card. Now you can enjoy using your computer with the new installed graphics card.

Yes the card does support the screen. If you have blank screen right from turn on, chack that you have not plugged the monitor into the onboard graphics port instead of your Radeon. If you have plugged it into the right port then you have hardware problems. Could be any of the following:
1. Monitior
2. Video Card
3. System memory
4. Motherboard
5. Powersupply
6. CPU

Try a different monitor and get back to me if you want troubleshooting tips.
Cheers

enable your onboard graphics and plug your monitor into the onboard. start up your pc and install any needed drivers for the secondary graphics card. right click on your desktop and go to your display properties you should see a faded out screen that has a 2 and a lit screen that has a 1 right click on the faded screen and check enabled then move your monitor cable over to the new vid card right click on the lit 1 and disable it making 2 your primary.

try a 3 way monitor vga switch 1 imput and 3 outputs to your monitors

BIOS Setup Utility; go to Advance Chipset Features
PEG Port is your PCI-EXPRESS…Enable/Disable

If you take the side off the pc case and look inside, you will see the back of where your vga lead is connected to from the monitor, if it is straight into the the motherboard, you have onboard graphics, if tou see your lead connected to agraphics card fitted into a brown (AGP) slot or a white (PCI) slot, then you have a seperate graphics card. If you have onboard graphics and suspect it is the graphics then you can fit an AGP graphics card and dissable the onboard graphics in the bios set up.
