Maximum resolutions for different cables

[Pada]

Hi all,

I would like to know what are the maximum resolutions for the different kind of cables: VGA, Single-Link DVI, Dual-Link DVI, HDMI & Display Port

One of the reasons I want to know this, is because I'm currently sitting with an Asus HD6970 DirectCU II graphics card with 2x DVI + 4x Display Port, but I'm unable to run my 30" Dell screen at 2560x1600. I've tried both the Dual-Link DVI & Display Port cables on all the ports.

Funny thing is it's supposed to work on 2nd DVI port as far as I know....

What cabling did you get with your monitor?

Does the card only have Display Ports or does it have HDMI port aswell?

The card comes with a shocking four DisplayPort 1.2 connectors, two DVI connectors of which one is single (up-to monitor resolution 1920x1200) and the other dual-link (2560x1600 and even higher). We had a problem though, on our 2560x1600 IPS screen dual-link did not kick in. We had to revert to a newer monitor over one of the DP ports.

This is from Guru3d's site....

Check the ATI CC...there is an option there related to large panels. Called reduce frequency or something like that.

Thanks for the replies.

The Display Port on my brother's laptop (Nvidia Quadro 880M) works 100% with my screen at 2560x1600@60Hz at 32bpp.

I'll give that ATI CC thing a go, but I'm not that keen of switching back & forth between graphics cards + drivers
I think I'm going to wait for Asus for a response on this first.

So it seems to me like the connectors:
VGA: limited to 1920x1200 (or perhaps even 2048x1536?)
HDMI 1.4: 2560×1600@75Hz at 24bpp / 2560×1600@60Hz at 30bpp / 4096×2160@24Hz @ 30bpp
Single-Link DVI: limited to 1920x1200
Dual-Link DVI: at least 2560x1600
Display Port: at least 2560x1600
