I am new to the world of hardware and spent the last 2 days trying to resolve this issue. I have had SAPPHIRE HD6450 installed in my PC. I have connected it with Samsung series 5, 27" monitor via the HDMI cable, and it was OK. now I am trying to add Samsung series 5, 42" LED TV as a second display. when I connect it to the graphics card using DVI-to-HDMI convertor it appears in my PC as a 2nd display, yet, the TV shows black screen and sometime "Searching for signal".
I tried switching the input between the monitor and the TV, it keeps showing the same thing. Any clue ?
