I use both DVI-I and DVI-D and they both work just fine. DVI-I has 4 analog signals which you will not use anyway. DVI-D just has the ground pin without the 4 analog pins.
What he suggests testing a single link dvi connection with a different monitor will work all day. The 27Q will not accept a single link video cable. (mine) You will get backlight, blue power led indicating that there is signal, but nothing will be displayed. If this is true about intel which does not surprise me at all because I have worked with intel on a dozen driver issues then you should just buy a video card and be done with it. Or you can try adaptive converters like hdmi to dvi dual link or dp to dvi dual link. This should increase the speed. Sounds like you will need the full DVI-D dual link signal or nothing will be displayed. Thats really the main reason why crossover distributors list it as not being compatible with HDMI on laptops. Same reason.
So just an hour ago I tested a 23" hanspree monitor and it displayed video in bios and os. My test consisted of HDMI to DVI-D dual link passive adapter, DVI-D dual link M/M cable and monitor had DVI-D dual link input. All pins were populated at the input DVI-D port on the video board. I assume it is DVI-D dual link since all pins were there for dual link. I am waiting on the answer from hanspree. The Z77 and H87 motherboard only support DVI-D single link max resolution 1920x1200. So you will only be able to run 1920x1200 through intel 4k graphics with hdmi output since it is single link only. Like I said you should still get video though single link (most all monitors will) but you will be unable to run 2560x1440 @ 60 Hz. Guy has a HP 27" 2560x1600 and his still displays video just fine but not in correct resolution. The crossover video board is unscaled and its crap for compatibility.
"Well I thought, let's get HDMI to DVI cable as it says 4k@24hz and 2560x1600@60hz so I bought one and what did it give me, NOTHING stil 1280x800!!!
Now I could be stupid and try getting HDMI to DisplayPort cable as a last try but something is telling me that this solution is also not going to work.
So THANK YOU intel for nothing your HD graphic card SUCKS big time and is totally useless even nvidia nvs295 (old piece of junk) is giving me 2560x1600."
Please read the chart for intel 4k specifications. http://www.intel.com/content/www/us/en/performance/performance-xeon-e3-1200-hd-graphics-p4000-guide.htmlEdited by Craigaaa - 10/5/13 at 4:18pm
