OK.
"First":
IMHO, an HDMI cable running alongside the wall, on the floor doesn't look that bad. This is subjective, but this is what I'll say: When anyone comes over and sees the most beautiful picture they have ever seen, at any time, at any place, including the IMAX, in their entire life . . . the black wire is the last thing they will notice. They will notice your seating, paintings, room treatments, and the food stuck in your teeth before they ever will notice that cable. This is what I have observed in any case.
I just had another virgin visitor to my home cinema. He said "You are totally %*#@^! crazy". That was a first! I've only had "You are completely insane", or " You are totally insane", or "Holy #%&!", or *diabolical laughter*
Second:
Please get your screen last. Don't make the unfortunately common mistake of some persons by either getting them at the same time, or even the screen before the PJ, as did AcuDefTechGuy. He suffered for it.
Please, please, please get the PJ first. Spend at least a few days playing with the pic on the blank wall. I myself took a whole week before ordering. It's not as easy to decide as you might think.
For gaming, please specifically ask David Gaudreau, and others. David was the one who getting nauseous, but yet he recently was raving about how amazing games looked with his PS3. IIRC, Clint DeBoer might've said that he prefers the larger screen for movies, and smaller screen for gaming. So, YMMV.
Ambient Light = Death for PJ picture. Its how it is. Sorta. I would seriously consider a High Power screen such as the one I use. Very affordable, very good at shedding ambient light, and some think its the bang for buck PQ regardless. Main compromises are narrower viewing angle (but I still fit 8 seats), and impossible to be acoustically transparent (which is $$$$ anyways).
The Epson 1080UB has been noted to be of excellent value. However, I would definitely take what ADTG says with some salt. The bulb is 170w and it appears this unit comes decently far enough away from a calibrated state. Tom Huffman at AVS has said to expect only 250-300 lumens in a calibrated state. Jason Turk, as well as Tom, have said that the QC is really all over the board with these units, particularly with panel alignment and white uniformity. Jason said he has had extensive experiences with these PJs, so much so that you cannot use other's settings for your own model.
That all being said, the Epson is still a value buster.
If you do get a high power screen, and its too bright for you at night, you can always add a filter to the PJ for night viewing.
However, due to costs of bulbs I would seriously consider my idea of the cheap flat panel behind it. Two bulbs are about the same value as a cheap flat panel. That being said, I just recently bought my first warranty in forever. Mack, that's been around 70 years, offered an AVS powerbuy. $260 got me 6 yrs on PJ, and 5 years on bulb, replete with two free replacements. Yeah, $260 is the grand total. Unfortunately, some azzholes took advantage and got bulbs for free without needing it, and sold them for great profit. So now you have to send in your old bulb. Anyways, I'm pretty sure the sale is over, but contact Mack, see what they say, and tell them jostenmeat sent ya.
When I send you a pic of the treatments sometime next week hopefully, I'll also send you a far-field (12-14 ft away) pic of the HDMI cable that runs along the wall, on the side. Its very subtle looking IMO. Well, that's just me.
Whew. OK. Just to get you all worked up my dear cbraver, here are some pics to salivate over. You'll see how there is no comparison in immersion. Pics are of a Samsung 71 series 46" LCD and 133" screen:
Wheeeewwww . . . . . . . . .
