Intel IGPs 1920x1200x60Hz limited to their DVI and HDMI

Intel IGPs 1920x1200x60Hz limited to their DVI and HDMI

Microprocessors Intel Core 3rd generation “Ivy Bridge” have been available for some months, but it is curious that recently some news media do note that although in theory their IGPs are capable of handling resolutions much higher than Full HD (1920 x 1080) in practice is limited to 1920 x 1200.

As seen on the websites of many manufacturers of motherboards, the Intel IGP Graphics HD 4000 and 2500 support a maximum of 1920 x 1200 at 60Hz when used their and outputs, although these same IGP that supports resolutions of 2048 x 1536 at 75Hz in VGA, and 2560 x 1600 at 60Hz in DisplayPort output.

Apparently this limitation is caused because their DVI / HDMI have only one link (single link), which prevents them from supporting resolutions up to which would require two links (dual link).

When this be a hardware limitation, users of monitors with resolutions up to 1920 x 1200 will be forced to use active adapters DisplayPort to DVI / HDMI, or use a DisplayPort monitor. It is believed that this limitation will not affect most users.
