Although I still dislike the Beovision Eclipse "Full LG" interface, I have finally found an interesting value in it for some users (which doesn't make it cheap but helps to swallow the price pill) : people who want to connect a video projector to their Beovision, let me explain :
The Videoprojector output is gone since the BV7/Beosystem 3. Since then, your only solution is to get at least a HDMi x*2 switch, or a HDMI matrix x*x. If you want full integration (control everything via Beoremote One), you have to get this switch/matrix from Atlona, which means, for a 4K HDR compatible switch, at least 800/1000€.
Side note at this step : people are complaining about the astronomical cost of the B&O "soundbar", but what about Atlona cost for simple switches : it's just "out of this world pricing"!!
So here is my idea : with the Eclipse, you get a B&O switch with an LG TV over it, linked by a single HDMI. Which means that with a HDMI mirror splitter between the Soundcentre and the LG screen, you get a HDMi output for a Beamer, without having to buy expensive PUC-compatible stuff (the mirror splitter always copies the input to 2 outputs). You'll be able to get all external sources to the beamer. And as I'm not very interested by internal sources for big screen, that's a very nice solution I think.
