GTX 680, Which HDMI Version?

post #1 of 5
Thread Starter 

Long story short, paid a low price on a Dell U3011 monitor without realizing the DVI ports are dead on it apparently. I'll need to use the HDMI inputs since VGA is crap of course.

 

Basically it needs HDMI version 1.3 or higher in order to accept a full, 2560x1600 feed from the card and display properly.

 

Does anyone here know if the 680 has HDMI 1.3+ outputs?

Reference GTX680's HDMI output is 1.4a. However, Dell U3011's User Manual states the highest/optimal preset resolution for its HDMI input is 1920x1200 (60Hz).
http://support.dell.com/support/edocs/monitors/u3011/en/ug/about.htm

Perhaps you can 'force' 2560x1600 (60Hz) onto that U3011 through the HDMI but I would suggest against it.

If the Dual Link DVI input of the said U3011 is defective, this means you should use its Display Port input which is also capable of 2560x1600 (60Hz).

And reference GTX680 does have a DP output.

Supremely helpful post, thanks very much.

 

Would a DVI to Displayport adaptor such as this: http://www.amazon.com/GTMax-Premium-Black-DisplayPort-Cable/dp/B002CSUZSU allow me to output a 1600p signal from my GPU and get a proper monitor feed? Or is it generally only going to work for a straight up, DP to DP connection?

 

Thanks again!

This is not going to work as the adapter/converter needs to be active for Dual Link DVI at 2560x1600 (60Hz).

Converting a Dual Link DVI to Display Port signal, I only know the Atlona DP-400 works for some people. It converts DL-DVI to mini DP and so you will need another conversion (from mini DP to DP) to get the signal from the GTX680's DL-DVI output to the full size DP input of the U3011.

Atlona DP-400 for US$80 (note that it needs to connect to an USB in order to be active, for 2560x1600@60 Hz purpose)

Okay so basically it's time to just nut up and buy a GTX 680 to get the native Displayport output so it can drive the U3011 properly.

 

Was kind of looking for an excuse to buy one anyway, though I wouldn't mind waiting on 4GB models.

 

The weird thing is all of this type stuff:

 

"The U3011 provides a ton of input options - two DVI-D ports, two HDMI 1.3a ports with Deep Color suppor"

 

"12-bit internal processing which tested HDMI1.3 with deep color (12-bit)."

 

Yet it then clearly states on their site:

 

"2560 x 1600 at 60 Hz (DVI/DisplayPort input sources) | 1920 x 1200 at 60 Hz (HDMI input source)"
