If your TV has a DLP-Link on/off setting or the choice between DLP-Link and IR in the 3D Menu's then the DLP-Link signal "issue" for IR glasses setups isn't a problem at all for you.
Even if you don't have that capability on your TV, there is no flash or flicker visible on an IR setup as a result of the DLP-Link signal for TV's like my old Samsung that do not have a DLP-Link on/off setting in the 3D Menu at all. What it does cause is an apparent hue to black and the hue color depends on the brand of TV. Samsungs have a deep dark blood red blended into the black which can be noticed in the credits screens of movies and such and I can never remember if the Mitsu's is a green or blue hue, blue I think.
There's at least one brand of IR glasses that DOES filter it out and eliminate that "problem" but they're crazy expensive.
There are no rainbows with the IR UC Glasses, at least not on my Samsung or my buddy's new 73" DLP Mitsu set with the two different brands of IR glasses being simultaneously used to watch 3D content on both TV's at different times for testing.
There's also no ghosting or haziness that I've ever seen with them either, although being in the incorrect L/R mode does make 3D look hazy and sometimes out of focus to me on my TV with an IR setup.
In the correct L/R mode with an IR setup on my old Samsung DLP TV that can't turn DLP-Link off, I'd say 99.999 % of the time the entire picture looks completely normal, always totally crystal clear, sync is rock solid even with the curtains open with 5 windows in the room during the day and no trees outside, and 3D just works.
Not everything black looks all colored up (tinted from the DLP-Link signal) with an IR setup on a TV that can't disable DLP-Link.
I only notice it on "fade to black" screens and credits screens normally, if at all. I could see where a space movie or space documentary might make it more apparent but I don't even recall seeing it at all during Resident Evil Afterlife or Avatar other than during the credits and it certainly wasn't a distraction at all if it was noticeable or I'd actually remember seeing it...
Plus I have a feeling I'd rather have the hue'd black than rainbows myself, but it really comes down to personal preferences and a personal decision/opinion which is least distracting from the 3D viewing experience or even downright annoying to see.
I strongly encourage people to try more than one brand of glasses and not just one type or the other (DLP-Link "vs" IR)...
There's no one perfect solution for the older TV's that can't disable the DLP-Link signal yet (that doesn't cost a major mint) and what works great for one person might look like total crap to someone else or vice versa.
There is no one "buy this, it's awesome" solution to 3D unless price and total cost is your main concern, in which case you can't beat the DLP-Link UC's for what they do at that price.
