Displayport to HDMI cord issue

[It_is_Owen]

Working on a Lenovo Think Center M91p, 1st screen VGA, second screen Displayport out, Displayport to HDMI cable, to HDMI input.
The PC doesn't recognize second monitor, so of coursr no picture.
However when I hook up an other monitor with Displayport to Displayport cable there is no issue.
Is there a setting that will enable the Displayport to HDMI cable to work?

I'll tried 3 different Displayport to HDMI cords, none of which work.

These cords have worked on other PCs around the office, it's just this one PC that it won't work with.

It depends on the type of the DP implemented by the manufacturer.

I'll order the connector and see what happens. Thanks.

You're welcome. Please post back the result.

That did it, it must be something to do with this being an older PC.
Thanks for the tip.
