Is there any different between passive DP and DP ++?

 

My MB has a DP++ port and I got one of the passive adapter, DP to HDMI, but it is not working, no AV.

 

Is that menas since my MB has a DP++ port, therefore I need an adapter which can do DP++ and pass thru DVI/HDMI signals?

 

Is that means there are 2 DP ports/standard out there, DP++ and DP, and DP++ can pass thru DVI and HDMI signals without conversion?

DP++ can transmits DVI/HDMI signals as well as DP (so a passive adapter is enough). DP transmits DP only; it requires an *active* adapter to convert DP signals to DVI/HDMI.

 

I assume you want to attach three DVI/HDMI displays. Then you will need an active adapter (~$30 like this) whatever i/dGPU you use (Intel/AMD).

renethx welcome back! We all missed you here!

 

Regarding my problem... my new MB has a displayport powering by the Intel HD4000 and should be DP++, which triggers passive DP signal, right? But I got one of the passive DP to HDMI adapter, se belo, but no luck. Any idea why?

Which mb are you using? I checked ASRock, ASUS, GIGABYTE Z77 mb with DP port, but none of them has this logo:

Thanks for looking into this one with me. I've the Asus P8Z77-V Premium.

 

I wrote to Asus Support and below is their reply.

"The display port provided by the Intel HD4000 is DP++, which triggers passive DP to HDMI cable."

P8Z77-V Premium does not have *DP++ logo* either. Perhaps better not trust tech support (the majority of these tech support people actually don't know technologies, even of their own products). smile.gif

LOL!!!

 

So I guess I need to be creative now...

 

What do you think one of below and DVI to HDMI converter them HDMI to my projector? I should have picture there, right?
