Just bought a new Radeon Pro Duo to upgrade my graphics card. Follow all steps (outlined below) and cannot get signal to a monitor.
AMD Radeon Pro Duo
Windows 7, 64 bit
no driver yet installed (can't get that far)
Philips 246V5LHAB 24" LED Monitor, HDMI cable (also tried DV-I, no luck either)
Intel Dz68BC motherboard, Bios Version BCZ6810H.86A.0021.2011.0831.1555
Intel Core i7-2600K CPU @ 3.4 GHz
Corsair GS 700 Power Supply
16 GB Ram
I had a pair of Radeon 6950s crossfired, everything with my current setup has worked just fine for years.
I uninstalled drivers for the Radeons, powered down, disconnected all cords, removed the old cards, plugged power cables into new card, plugged new card in place securely, (the locking device fits as it should...) plugged all cords back into computer, powered on the computer. Nothing seems amiss, except that no signal is being sent to the monitor.
The card seems to be getting power, the fan is spinning, all lights on the computer seem normal.
Powered down, unplugged, removed the card and reset it in place firmly but cautiously just in case I had not seated it correctly, still no luck.
Tried powering down the computer, unplugging everything, holding the power button for a minute then replugging and restarting... still no signal.
Removed the new graphics card and switched back to the Radeon graphics card, and everything works just fine... signal goes to the monitor and the computer is working as usual.
Not sure what else I should do. As far as the specs read my system should support the card... my memory is the minimum that the card requires but I don't think that should prevent signal from reaching the monitor.
Thanks very, very much...
It was INDEED the BIOS that needed to be updated. I have never updated the BIOS since I put the computer together in 2011. Was a bit messy, I feared that I bricked my system when it would not reboot after updating... but the computer gods smiled on me and with some back and forth the GPU finally sent signal to the monitor. Took me another long stretch to get the drivers installed, but all is well that ends well.
Answering your question... I had a DV-I to hdmi cable plugged from motherboard to monitor... moot now, but I was just trying ANYTHING.
