Super quick 'which connection' question...

[Chris [BEANS]]

Hi, just unwrapped one of these and I'm about to hook it up.
I need to decide between DVI or HDMI.

I'm hooking it up to a GTX 670 as the primary monitor and I'm using seperate speakers so audio is no concern.

If it matters I've also got the TV hooked up as a duplicate screen for occasional use for gaming with a pad.

Google seems to suggest there's no difference, but considering the (advertised at least) 1ms response time, just thought I'd check here with people who know!

TL;DR:
Shouldn't make much of a difference, but use a DVI, if possible.

Long version in the spoiler.

Theoretically, there shouldn't be a difference between DVI-D and HDMI. But unfortunately, there might be some HDMI "optimisations" that GPU manufacturers include in their graphics cards. I think AMD has some weird overscan by default, while nVidia apparently has limited color range by default (16-256 instead of 0-256, IIRC). Or at least this was the case at some point (and possibly only with TVs), not sure what's the situation right now. Furthermore, both anomalies could be overridden through the settings. In any case, I would use DVI-D, if possible.

On the other hand, with TVs there is a more definite (theoretical) advantage to using DVI with computer input:
When using DVI, the audio flag is automatically disabled by the GPU, which in turn allows 4:4:4 pixel sub-sampling (more correct colors, but not to be confused with the above mentioned 16-256 issue). TVs usually don't have DVI ports, but there are DVI-HDMI cables, which by default also disable this flag (when using the DVI port on the GPU). Although, this is also a problem that was occurring few years ago, but not sure how modern TVs and GPUs handle these things. In any case, if possible, I would use DVI-HDMI (or DVI-DVI).

Do note, this doesn't affect game CONSOLES, as they don't output 4:4:4, in any case. But if you're outputting via computer, this can change the outcome.

PS. As you've probably already concluded, it's indeed best to stay away from D-Sub. That makes the image a little blurry.
