If you don't need audio, is there any significant advantage of DisplayPort over Dual-DVI?
Another benefit is for multimonitor setup. DisplayPort 1.2 supports
daisy-chaining, i.e. routing data for several monitors through one cable. In such case you connect subsequent monitors not to the video card, but to the previous monitor in the chain. It reduces cables clutter.
Was planning on getting a Dell U2412M to replace my ancient TN panel HP monitor once I get my PC build up and running. At the moment the 27 inch 1440p model is on sale but it's still twice more than the 24 inch one. Too much, way way too much..
I thought of getting Dell U2412M too, but ended up buying U2413 which has
lower response time (so it's better for gaming). It has also better colors, though it's more expensive. Also, Dell already made the next iteration to replace U2412M, namely
U2414H. It has a downside however, like Guy N'wah noted. They cut the resolution down to 1920x1080. I don't like this trend. Luckily U2413 was still 1920x1200.
I remember the day I switched from my old 17" dinosaur to my current 24" monitor a few years ago. I thought that was kind of overwhelming, and it did take some get'n used to. And so much more room on my desk...for all them empty soda cans : /. Yeah, I don't see myself going bigger than that any time soon.
Yeah, I think 24" is more or less an ergonomic limit for the desk monitor. Higher than that is uncomfortable to me. But resolution can be higher with the same screen size still.
