Hi All, Thanks all for all your replies. The good news is that R720 does work with GPU. I tried with AMD V4900 and that did not show output. The missing part was - the onboard Graphics card needed to be disabled for the PCIe graphics card to work (from BIOS settings). I have been using AMD V49000 that and works without any issues. Thanks, Mo  
Hi All, I have added a Video Card i.e. ATI FirePro V4900 to Dell R720 PCI Riser Card. Downloaded the Catalyst software for ATI cards, installs ok. Windows Device Manager shows the card working ok - no issues. However when I connect the output from the Card a) DP (on card) to HDMI (Monitor) -- No output b) DVI (on card) to HDMI (Monitor) - No output The HDMI port on monitor is ok because it works with another Desktop PC and also the cables are ok too. I can see the output from Server on VGA port because of the built in onboard graphics display. I even tried putting a NVidia 8400 card but same issue i.e. no output however drivers are installed ok and windows shows device is running ok. OS: Windows 2008 R2 64 bit Is it something to do with the onboard graphics and would disabling that fix this or is there some other solution for this? Would appreciate your suggestions... Please advise. Thanks, Mo
