I count 3 connectors on my ATI Radeon HD 5450:
- DVI connector
- HDMI connector
- VGA connector
I connected a monitor via VGA, then got another TV screen by connecting HDMI and everything worked fine.
I recently acquired a monitor with DP and bought a DP to DVI converter to connect this, but it didn't work. I have tried:
- another DP to DVI and nothing converter
- another DVI cable
- restarting (which too many times I've done and nothing happens )
The only thing that remains to me to know is if the DP to DVI converter can work at all, which would be illogical to make them if not.
