this is wrong. there are several people in the Catleap club who can confirm running HDMI at 2560X1440 as well as the specs for HDMI 1.3-1.4 prove it has the bandwidth needed to support this resolution.

2560X1440 ~220MHz HDMI 1.4 can do 340MHz

You can not use an HDMI to DVI cable due to it only being single link. You would need an active adapter (like the display port one) to convert the single link Input (such as HDMI/DP) into a dual link output.

They do not make these adapters for HDMI but you can run a straight HDMI to HDMI at 2560X1440...

Just don't want people to get the wrong idea about HDMI capabilities

is it because i have an eyefinity video card that Passive won't work ? I only have one dvi hooked up I was under the impression if you needed to use more than 2 You needed another Display port with Active
Thanks again to everyone for the help

There isn't any difference between Display port and Mini-displayport other than the connector size. What I was trying to say is that you need an active adapter in order to push out the 1440p resolution. I believe non-active adapters are limited to 1080p.

I was under the impression it was a hardware limitation (not the right pins), not that it was a bandwidth thing.

And yes, you are going to need the active (powered) adapter for 1440p. thumb.gif

Can anyone link me to displayport to dvi that would work all the ones I'm finding online say supports resolution upto 1920x1200 eventhough they say dual link dvi

you are correct it has to do with HDMI being a single link connection and not a dual link connection so any HDMI-DVI adapters only have a single channel of output IE; single link dvi.

Display port is the exact same and that is why they need Active adapters to convert the single channel into dual channel.

The phrasing of your first statement made it seem as though you didn't believe any way shape or form of HDMI could out put 2560X1440 when in reality it can.

Here is an active mini DP port adapter that can do 2560X1440.

Nope, that's exactly what I thought. I didn't know there was a way to turn ANY signal on a HDMI cord into 2560x1440. For example in audio once you loose quality via a connection there is nothing that will bring it back. But from what you're saying two compatable devices could do 1440p if one pushes enough info through the HDMI (standard) and the other device knows how to read it, in our current case the 'dummy' adapters can't decode it into dual link DVI.

Guess who can't wait to get home from work?





And guess what? Perfect pixel smile.gif

Damn.... That looks AWESOME!!!!

Who did you buy from? Did you pay any extra for perfect pixel?

Funny route your package took Yak, Alaska to Tennessee and back to Oregon. Postal efficiency at it's finest. wink.gif
Mine went from Korea to Hong Kong and left HK customs about six hours ago. Lets see where it lands in the US!

I bought it from "fastterakorea". It's a QH270-IPSB. I didn't pay for perfect pixel, $316.60.

I'm not sure why they go to Tennessee. I think it may be because they don't fly FedEx from Alaska to anywhere else. Not like there aren't enough flights.

That happened to mine. Despite living in Los Angeles, mine went to Memphis.

BTW, Grats on your new Shimian and welcome to the club. thumb.gif

It looks like an IPSI
