Display port cable

I have a Hp Pavilion p6-2100 computer and I bought a HP elite L2201x monitor. The monitor has a display port cable.My question is if I buy a converter to hook up to my HDMI port will this work with my model?

Re: Display port cable

Hi,

 

They both use digital signals. A DP-HDMI cable should work.

 

Regards.

Re: Display port cable

[ Edited ]

Most DisplayPort to HDMI cables are passive and designed to work in one direction only. That direction is from the graphics card DisplayPort output to the monitor HDMI input. The DisplayPort specs state that when a DP-to-HDMI or DVI adapter cable is connected to a PC that supports DP++ (Dual-Mode) capability, the PC senses the presence of the adaptor and sends HDMI or DVI signals over the DisplayPort connector rather than DisplayPort signals. No signal conversion is performed by the HDMI or DVI adaptor. HDMI and DVI signals are merely passed through.

 

Going the other way requires a very expensive active convertor such as the "StarTech HDMI® or DVI to DisplayPort® Active Converter" to work properly. Even then, there are many reports of this solution not working as described.

Re: Display port cable

Hi,

 

Thanks Frank. I think the reason behind is HDCP therefore they only make one way.

Re: Display port cable

@ banhien...

 

Please read the FAQs at DisplayPort.org for more information on this subject.

 

From http://www.displayport.org/faq/

Q: I just purchased a monitor that only has a DisplayPort connection. How can I hook this up to my computer that only has VGA, DVI or HDMI?
A: There is not a cost effective way to do this. The adaptors that are available only work from a DP computer to a VGA, DVI or HDMI monitor and not the other way around. If you have a desktop you can purchase a graphics card with DisplayPort. Our best advice: Before you purchase a DP only monitor make sure you have DP on your computer.
