Not exactly.
For a computer monitor to be compatible with Nvidia's 3D shutter glasses, all it needs is for it to be 120Hz. The connected computer has a USB dongle which the 3D glasses sync with. For a TV to really 3D capable, it has to have the dongle built in, and be able to interpret a 3D signal (HDMI 1.4a[1]). What confuses the issue is that most TV's and computer monitors these days have both HDMI and DVI ports on them.
