I'm pretty sure this is just a function of the GPU that your laptop has to happen. I know the last two laptops I've had have had DVI; HDMI is probably more common now but you can get an adapter.

I've ordered a desktop anyway.

About DVI and HDMI: I said "DVI" in my post because last time I built a PC was 5 years ago and then it was standard for monitors and graphics cards to use DVI.

The screen I got is pretty modern and recent I guess, and it has the following information for its connector:

"D-Sub, DVI-D (HDCP)"

So it's still DVI, I see no mention of HDMI there.

Is HDMI better than DVI? Or is it something only for laptops maybe?

The video card specs says:

"HDCP Ready
Connections: 2x DVI (2x DualLink), 1x Mini-HDMI (1.4a)".

I hope this "HDCP Ready" means "ready enough for this DVI-D (HDCP) of the screen"? Because "ready" does not really sound like "fully supported" to me. It will support this monitor, I hope, right?

HDMI is the standard for TVs, game consoles, and home theatre setups, in a large part because it ships both HD video *and* sound over the same cable (plus a limited degree of control signals).

Most decent monitors provide HDMI in addition to DVI these days, incase you want to hook your PS3/XBox/Roku up to them. And as you can see, modern video cards have started offering HDMI as well.

'Ready' means 'fully supported' in this context.
