Real world support via specs

Be careful, as most laptops will not support anything higher than 1920x1200 via HDMI or VGA connections.

HDMI often supports much higher res than that: The HDMI spec since 1.3 (2006) certainly allows for it.

The problem is that many many graphics chipsets don't allow that.

For example, the latest Intel HD graphics will not support anything higher than 1920x1200 via HDMI or DVI connections. You'll need a DisplayPort connection for anything more (the DisplayPort will support up to 2560x1600).

Note the "2012 Display Overview" section on this page discussing the Intel Ivy Bridge graphics implementation.

"Moreover, there are a few limitations in resolutions and monitor connection types. Theoretically, a desktop system on an Ivy Bridge processor can offer three outs: the first one - a universal out (HDMI, DVI, VGA or DisplayPort) with maximum resolution of 1920x1200, the second one – a DisplayPort, HDMI or DVI with up to 1920x1200 resolution, and the third one – a DisplayPort supporting higher resolutions up to 2560x1600. In other words, a popular connection option when WQXGA monitors are connected to Intel HD Graphics 4000 via Dual-Link DVI is still unavailable"

Some of the AMD and Nvidia chipsets allow higher resolutions via HDMI (and make sure to check each chipset on a case by case basis when buying a laptop, as not all of them will support more than 1920x1200).  You'll also find limitations on refresh rate at a given color depth and more when trying to support anything higher than 1920x1200, even if using a video chipset that allows a higher resolution.

In any event, if you get a typical mainstream laptop using integrated Intel graphics, you'd best make sure it has a DisplayPort, as you're going to be limited to a maximum resolution of 1920x1200 via other port types, even with a laptop using the very latest Ivy Bridge CPUs with the latest integrated HD 4000 Intel graphics.

Sorry, they just do not support more than 1920x1200 resolution via other ports types.  Some of the newer Nvidia or AMD graphics chipsets can go higher. But, with Intel, you need a DisplayPort if you want more than 1920x1200.
