I know this is an old post, but I stumbled on it and thought I would put in my two cents.
I own 4 Yamakasi 301 Sparta monitors. Very similar to the one in the question. They are 30" 2560x1600 displays. They do not have an ad board. I use them for my home office. I have a GTX 770 and a GTX 750 driving the video signal. I have only been able to get them to work using Dual Link DVI. I have tried all manner of converter to try and connect them via display port and via hdmi and have never been successful.
I also have a 13" macbook pro with the 2560x1600 display. It has 2x mini display port and HDMI. I have also tried to connect the monitors to my macbook pro and have never been succesful. I did on one occasion get the macbook pro to actually recognize the monitor, but was only able to get the resolution up to 1280x800.
Personally, I would recommend not getting monitors with no ad board unless you are going to have them connected to a desktop with a dedicated video card 100% of the time. And it's better if you keep your computer running most of the time. They have caused some headaches. Every now and then I have to unplug the video and power cables, disable and re enable my video cards, and then plug them back in to get my computer to recognize them. This happens after driver updates or sometimes when my computer restarts. It's not a huge deal because it doesn't happen often, but it's still a pain having to crawl under my desk and try and disconnect the cables. I bought them to save money, but in retrospect, I wish I would have just bought monitors that had an ad board that were more flexible.
Another thing to note, which may or may not apply to all monitors with no ad board, but may be worth noting. I have burned through 3 power supplies. Not sure if this is just the particular model I have, but the power supplies that came with the monitors are I believe 140 watts? They get very hot, and 3 times now have gotten so hot that components in the power supply actually came soldered from the board and fried the power supply. In one case dripping capacitor fluid all over my carpet. This has happened over the course of 2 years, and the replacement power supplies aren't very expensive, but they haven't always been easy to find. The ad board free monitors all seem to be fairly cheap from what I've seen, which is fine because that's the reason I purchased them in the first place, but it's important to know what you're getting yourself into.
Hope this helps someone.
