DLP-Link uses an integrated flash (originally a white insert flash (*) with older 3D projectors but later models moved to a red flash) to provide a sync signal to the glasses. This additional sync flash slightly tints / washes out the perceived onscreen image, but part of the DLP-Link system ensures the glasses are in the closed mode during the sync flash cycle. Meaning there's no tinting or washing out of the image when wearing the DLP link glasses.
(*) The decision to go from a white to red sync flash was smart, as there were times when an almost all white scene could confuse my DLP link glasses and cause them to loose sync. The red flash sync flash in newer projectors would require an exact red frequency scene to cause that same type of sync issue, and should in theory be extremely rare.
RF glasses use radio frequency to lock sync to the 3-D glasses, so the on-screen image has no sync flash insert added. RF glasses are always locked and unlike IR or DLP link, is almost impossible to trip up. DLP-Link is pretty good but on a few occasions I've had stray light sources cause some issues.
Many RF emitters have tuning modes where one can tweak on the sync reference if needed. That's great if you buy a new projector and even a different model, or going from DLP to LCD or vise versa, it often can be possible to simply move the RF emitter & assorted glasses from one projector to the next.
Because RF doesn't alter, tint or wash out the on screen image in any way, if one has content that is mixed 2-D and 3-D (The Mask 1961, Spy Kids 3 and Spy Kids 4, Tron Legacy, etc) if one wanted to take off their 3-D glasses during an extended 2-D sequence, they can do so and see a normal 2-D image.
A VESA sync output not only allows for RF glasses but other possibilities as well, including the older IR glasses or for elaborate set-ups such as polarized 3-D with an electronic z-screen filter and silver screen.
DLP-Link is TI's way of at least getting 3-D in under the radar and doesn't take much to implement. And that's great as if it gets some manufactures to include 3-D in model in at least this mode at a minimum.
But a VESA 3-D sync port provides one with more options if they are so inclined, including the use of an optional emitter with RF 3-D glasses.
