DVI-D, 10-bit colour and scaler conundrums

Yo.



TLDR if you can't be asked to read below:

- Can DVI-I be converted to DVI-D Dual Link with any sort of cable, does it actually work?

- Is 10-bit colour going to make any difference to me, a user coming from a TN 24 inch Samsung monitor @ 1080p?

- Is the Dell U2713HM a good choice over the Hazro 27" on OCUK? I kind of want the option to plug other inputs than DVI-D (which I don't even technically have) in

- Would my HDMI > DVI-D cable work with one of these monitors with a single input and no scaler?



I was eyeing up the Hazro 27" display that is on the OCUK site here: http://www.overclockers.co.uk/showproduct.php?prodid=MO-019-HO&groupid=17&catid=1120.

I have managed to buy a GPU that only has DVI-I which is an absolute ho because it isn't meant to work with these monitors with DVI-D connections. Of course I have HDMI and 2 Mini-DP too. I was just expecting these higher end monitors to rely on the DP standard when they all seem to rely on DVI-D dual link which is... weird.

Here's another funny thing to think about. I'm currently using an HDMI > DVI-D Dual Link cable. As far as I know, HDMI 1.4b (What this GPU has - MSI R7950) supports up to 2560x1600 @ 60fps. That, in theory should do for a 2560x1440 monitor with no scaler. Now what I want to know is, is this monitor using anything internally to accept an HDMI > DVI-D signal, or is the cable doing it for me? This doesn't look like an active cable so I'm assuming the latter but I can't be sure, I'm not great with this stuff.

Any help is appreciated, thanks.

Uh... DVI-I means it can do both DVI-D and VGA signals. As for HDMI, it uses the exact same signals as DVI-D, except it's also capable of carrying sound. All you will need is a dual-link DVI cable (which should be supplied with the monitor). What GPU card did you buy? Usually on AMD cards only the DVI-I port is also dual-link DVI-D (Other DVI port is just a single link DVI-D), where as on Nvidia cards it's usually both DVI-I ports that are dual link.
 
In addition to other replies:

From what I've seen, all passive DVI-HDMI cables are actually single link. Therefore, you can't output 2560x1440, only 1920x1080.

Some DVI-HDMI cables even have pins for dual link, but can still only output single link. Here's a very informative buyer review quote (edited for clarity and typos) from one such cable, and sums up the situation quite nicely:

"I found out after buying this product that there is no such thing as HDMI-to-dual-link-DVI. Dual link DVI means two TMDS links. HDMI has only one TMDS link and it is therefore single link. HDMI is theoretically capable of high bandwidth and very high resolutions like WQXGA (2560×1600) for example. But the way that works with HDMI is a super high TMDS link, the fact is that there just aren't any high resolution devices (displays over 1920x1200 ) that can run off HDMI. This converter has all the pins but it won't actually do anything for you."
 
Right, that's a great help.

I knew DVI-I did both signals but had no idea if it did dual link XD That's great to know.

I feel so stupid now ._.
