DVI-D vs Display Port (with GTX 660 and ASUS PB27Q)

post #1 of 4
Thread Starter 
Is there a difference in image quality?

I'm pretty sure the answer is no, but I just want to check with you all you knowledgeable people to confirm. I have a GTX 660 and I've read---although you can really find and read anything on the internet---that sometimes display port doesn't require any conversion as DV- D does? Not an anlogy / dig conversion, but something else. I think this isn't accurate.

Anyways, I'm not concerned with daisy chaining or audio transfer. Just want nice colors and 1440p resolution.

Thanks for your assistance smile.gif

Most people go with dual-link DVI for 1440p monitors since most monitors do not yet support native Displayport and still rely on some form of conversion between inputs.
Image quality-wise there shouldn't be any difference however monitors that offer multiple connections often have higher input lag than monitors with only one connection.
An example would be the Auria 1440p monitor vs the Yamatski/Catleap 1440p monitors. Auria offers multiple inputs but suffers from significantly higher input lag versus the two other Korean brands with only a single DL-DVI input.
That's about the extent of my knowledge.

Running that exact display (though multi) on my titans. My advice is this: NV drivers are major blowhard when it comes to DisplayPort reliability (at least they are with the Titan) and it results in black screen of reboot, heinous lag to wake the monitor, and serious issues with multi-monitor stability in games. That's why I've switched back to DL-DVI.

Quality-wise, it was the same.

Interesting. I've been having issues with sleep and resume from sleep with my ASUS PB27Q. Going to try to DVI D now.
