Hello there...I'm in a similar position in that my old Epson H262A has started making noises that sound like a dying cat. So...I'm looking to upgrade for the first time since 2009ish!
First of all, should I care about stepping up to 4K or not? I'm currently pulling/watching most content from a Chromecast.
Secondly, my room has a 12' throw that provides my 100" screen. I'm assuming that I'll need a projector with a proper lens shift. Just wanted to know of any options y'all might recommend!
Thanks so much!

I just purchased this projector used from eBay, it seems to be in very good condition and turns on with no issue but the focus ring does not turn at all. the zoom ring turns fine and so do both lens shift dials does any one know what would cause this? if you own this projector when you turn the lens focus normally does it turn on the end of the lens or does the lens turn in side of the machine it self when adjusting focus? im just trying to figure out if it got jammed up in shipping. the appearance does not suggest that it got damaged though the focus ring shows no damage or not being aligned with the zoom ring etc. thanks for any help.

I have had the Powerlite Home Cimema 1080UB for 6 years with a Severtson 109" Custom fixed screen. The projector is 14 1/2' from screen, ceiling mounted, and the the viewing position is at 13 1/2'. I get 600 to 1000 hours out of bulbs I buy on ebay, not OEM, but at about $80.00 @ they are much cheaper. The light output on OEM bulbs seems to fall off at this number of hours so it doesn't seem to make much difference. The ballast board failed 3 days ago and would not ignite the lamb. The new ballast board should be here tomorrow. It's a 33 screw uninstall so I wouldn't recommend doing it yourself unless you have some electronics background. 6 years of good service is outside the life of most pieces of electronics equipment being designed today, so I would recommend the 1080UB regardless of where it comes from.

Do these bulbs have a polarity? Or, does it matter which lead goes to which post on the connector?
I recently purchased some bare bulb replacements for my Epson HomeCinema 1080UB, which takes the ELPLP39 lamp. I had a previous cartridge with a blown bulb in it, so I got a set of 3 of these bare bulbs to rotate through the two cartridges I have.
Upon closer inspection of the bulbs, I see that the 2 leads coming from the front center of the lamp (where the thin glass bulb is located) and the rear center of the lamp (where the ceramic is located) are not always wired to the same post on the connector. The connector will only fit into the cartridge/housing in one orientation, having the "larger tab" facing outward (toward screen, or "front"). One bulb may have this "large tab" post wired to the front of the bulb, while another bulb will have this post wired to the back of the bulb. So my question remains...
Do these have a polarity? Does it matter if the front or the back of the bulb is wired to the "large tab" post, or vice-versa? Or are these bulbs strictly AC, in which case it shouldn't matter?
I realize that the connector must be positioned correctly within the cartridge in order to be inserted into both the cartridge and the projector itself, but if the leads are reversed on the connector-to-bulb front/back wiring, do I risk damage?
