W1080ST

Those are really not that great for a 3 meter screen. I just upgraded from a GV50 to a w1080st because the GV50 was really not that bright. What I suggest is get a second hand name brand projector (like a w1070 or others) and a firetv stick or xiaomi tv box. You'll be way happier. Right now I'm using the w1080st which I got for 250$ and a 50$ xiaomi tv box and it outperforms the GV50 in everything, especially price. Keep in mind I was using the GV50 on a 90 inch screen, not a 120. Even if you need portability, I'd look for something that has at least 700-800 ANSI lumens tested by a third party. You have the budget for it. Edit: Even tho the build in OS seems like a good idea, the GV50 was slower than my xiaomi tv box (both have Google TV integrated) so I just used the xiaomi box with an HDMI.

Skip the PJ40. Pickup the BenQ W1080 or the Optoma HD142X

It’s built better and uses real lens optics. I wouldn’t even bother with the Ultimea unit. Pick the BenQ W1080ST unit.

To be fair you should be looking more like $1500. I picked up my BenQ W1080ST (short throw version of the W1070 essentially) 12 years ago for just under $1000, which was a good price at the time. Inflation has eaten a good chunk of value in the last 10+ years.

A good quality 1080 projector that can pass through 4K content is fantastic (especially on a 100 inch). I have a 1080 BenQ and haven't felt the need to upgrade to 4k yet. I get the mastering and bitrate of 4K discs, just not the actual raw resolution. I didn't have to spend over $1000, not even close. In fact I spent $425, which is *insane* for the level of quality. It works out very well. Though I may have to change the bulb soon lol.

It's good. Many of us have been down your road, till we understand that there's always better projectors that can fit a budget. I had a 720, moved up to be BenQ 1080p, and an Epson 1080p. I'm thrilled with these two and one day, when I get some cash, I'll try a 4K. But you're doing good. And they won't be as loud.

Projectors last a long time, so spend the money on a good one now. I picked up a $750 1080p Benq, expecting to replace it within three years. It's been eight. I'm now willing to drop $5000 on an Epson LS12000 because I now know it will last me a decade. Silver Ticket screens are solid. Sure the Steward is better, but there's diminishing returns after a certain price. You can always upgrade your screen at a later date, but I doubt you'll feel the need.

Have a look at Richer Sounds. I picked up a BenQ 1080p projector for £200 and gor a discount for signing up to their newsletter. It was a return / open box. I was projecting almost my full wall height - it was amazing. Room layout change means a smaller projected size now but still great.
