Are there any Dell laptops which have both HDMI outputs AND HDMI inputs? What about other manufacturers?

I want to have a portable compact solution (i.e. laptop) for testing the HDMI outputs of various types of audio and video components without having to connect them to a HDTV or to a 21" HDMI-input monitor, for example.

The HDMI input support hosted on this theoretical laptop must support at least HDMI 1.3 with full multichannel LPCM audio.
