DVI-D to (mini)DisplayPort Adapter/Kabel

[ochsenbauer]

Hi,

I have a MacPro3.1 with the NVIDIA Quadro FX 5600 1536 MB grafikcard. I want to use the Dell U2515H monitor, which only has HDMI, mDP und DP connectors. Which cable or adapter can I use to get the full resolution of 2560x1440?

I have already tried:

• Apple Mini DisplayPort to Dual-Link-DVI-Adapter
• Apple HDMI to DVI Adapter
• Amazon HDMI to DVI-D Adapter Cable

With these I only get a resolution of 2048x1152.

Does anyone have a idea?

Have you tried creating a custom resolution using switchresx?

I'm afraid nothing will help.

your display needs dual-link dvi signal on hdmi input, hdmi can provide it if connected to hdmi port on videocard. But all dvi->hdmi adapters I saw only pass single-link dvi signal, hence 2048x1152. Displayport adapters wont help either, they convert from display-port to dvi, not vice-versa.

You either need a display with dual-link dvi input or upgrade videocard.

switchresX wont help either.

but wait, it was 1800$, not worth it.

Aaah I misread I thought he wanted to go mDP on Mac to dual dvi, it was the other way around

Thank´s for the information.

The conclusion is: If I have a dual DVI connector on the Mac I need a dual DVI connector on the display to get the full resolution!
