On my ThinkCentre M92p which has Windows 7 pro installed I am using a standard monitor from the onboard VGA.
But now I want to run a 2nd display to my LCD TV. So I have a new cable into the onboard displayport and the other end is HDMI into my TV. Nothing showed on the TV (no signal). So I went to the display settings and click on Detect but (Another display not detected) came up. Then I went into BIOS and set up the video to Multiple Displays. Still No Signal.
As far as I know I have the correct drivers for this model from the support downloads. Driver (b2vdo41us14.exe)
I am hope now someone can guide me through what I am doing wrong. And be thankful for any input.

What is your BIOS version ? And exactly what cable are you using for DP to HDMI ?

That BIOS is super old, they're up to version 95 now, and the readme doesn't go back as far as yours. Just to eliminate the possibility it could be associated to the problem, I suggest updating. Best to use CD ISO method, you may need to reorder the boot for DVD player before HDD.
Is there a brand associated with the cable? (Many threads here of DP adapter that don't work or work marginally.)
I know that on my TV, computer input is on a particular port, have you checked the owners manual and searched forums?

Does your monitor have a HDMI port? Or can you borrow one, to test with? It should display with only the DP port connected.
Check Windows Update / Optional updates, for a newer graphics driver.
These adapters from the AMD list, more are on page 2, you don't want the 'mini' adapters, and either passive (lower cost) or active will work.

I bought an passive adapter today and plug it into the DP and then a HDMI cable into that and my TV.
YES I have a signal. Picture and sound works perfect.
Retried the other DP to HDMI cable and still nothing.
It's funny because this cable had worked before on another PC with a twin Displayport graphics card.
Thank you BiggAl for your help.
