“i have the same issue with my Epson Home Cinema 3800. It’s just over two years old so the warranty expired. The unit tries to start up and goes into a flashing Temp warning kicking on the loud fan even though it’s not warm at all.”
“As for the quality, it simply blows us out of the water—shows in UHD HDR have brights that are almost like looking at the sun—some people call it a “light canon.””
“I have the Epson Home Cinema 3800 and it’s pretty legit for most small scale use.”
“I was very happy to find the 3800 because it provided a simi-affordable 4k upgrade while still being 3D ready. Not a bad projector for what you get.”
“4K @ 60fps. Epson Home Cinema 3800. Just upgraded from HC 2030. Still need to make screen adjustment but huge difference! Biggest I have noticed though is the input lag. I went from 118ms to 16ms.”
“Not the Epson Home Cinema 3800 / Tw7100. Edges go blurry. :-(”
“I have an Epson Home Cinema 3800 (1.5k) and the HDR is incredible on it. Nearly shit myself the first time I watched "Our Planet" on Netflix. The UHD Blu Rays look incredible too.”
“i have the same projector but unlike yours, I am unable to have frame interpolation and 4K enhancement on at the same time.”
“I had multiple 3800's and they suffered from uneven focus if lens shift was in use (shifting the image more than about 6" would decrease focal uniformity with my set-up).”
“I just upgraded from a 3700 to a 3800 projector and am having a problem with uneven focus. Parts of the screen are blurry while other parts are crisp.”
“I'm loving mine, great picture at 100" in a slightly lit room (the wife likes it that way). Very sharp even if it's not real 4k. Only thing I'm dissapointed in is HDR, even with all light out, it remains too dark”
“IMO I've owned both and I find the Epson superior all around, my input is you don't need the 5050UB to beat this machine”
“My second was a bit better but there's a dead pixel right in the center. Sending that one back and keeping the first with the out of focus 2 corners.”
“I game on my Epson Home Cinema 3800 w/ 120" screen. It's fantastic, and pretty hard to go back to something smaller.”
“I did and I'm happy with it but honestly haven't been using it all that much. As I moved away from physical media to streaming, I find myself using the Sony X950G that the projector screen lowers down in front of.”
“We casually game on an Epson Home cinema 3800. Some online content. No issues at all, it’s awesome.”
“The 3800 had very, very well known soft focus issues in the corners. The general Epson rule of thumb is save $$ until you can afford a 5050. Look for factory refurbished units directly from Epson on Ebay. Skipp the 3800”
“It's much brighter, the colors are amazing, the 1080 "4k enhancement" is impressive, but this project suffers from focus uniformity.”
“with real world content it is only noticeable with subtitles or so but with a pc connected it looks quite ugly in the bottom left corner...”
“I am having issues with this projector. First, let me say I love it. I would hate to have to change to a different model.”
“I have a pixel shift Epson (home cinema 3800), and can confirm Plex does recognize it as a legit 4K player. Files play like a traditional 4K display no issue and picture is great.”
“I went with the Epson Home Cinema 3800 its at bb for about 1200 at the time. To me its incredible. Not the greatest in bright daylight but at nights it like the movie theater.”
“just picked up an Epson 3800 and the left lower side is slighlty out of focus when the rest is in focus, cannot get all even.”
“Well tuned they are excellent but you have to really put the work into these to get them to this point.”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“The Epson 3800's fan noise isn't too bad. At the worst end of the spectrum: on 'Dynamic' picture mode with 'High' lamp setting I think the review found it measured at about 35db. I don't have a meter to measure mine, but it's noticeable during quiet scenes at this setting.”
“Yep, I have a soft focus spot in the lower right hand corner. While I didn't have this issue with my HC3700, I'm still not completely ready to blame the projector for a few reasons.”
“The 3800 is still a great projector - it does >a lot of things< very well. 4K60 sports or events in a bright room - set it up anywhere! - wireless input! - even OK without a sound system! Your peeps will love it.”
“I got the Epson 3800 over the Benq HT3550 1.5 years ago due to the brightness performance in not-so dark conditions.”
“I went from a 3800 to a 4010 to a 5050. The 4010 was a huge step up from the 3800.”
