### ⭐⭐⭐⭐⭐ Best Bang For Your Buck - Quality and Cost
*by  on Reviewed in the United States January 9, 2024*

I have to say I am thoroughly impressed. Pretty much a WOW experience from the second I turned it on.Bright and vivid colors, even in a lit room. 4000 lumens in 4k is pretty hard to beat at this price point.Believe me when I say that you get way more than you pay for with the PX748-4K. I had an Epson home cinema and this blows anything out of the water in the $2k and under category.Don’t hesitate to buy if you are looking. My Xbox looks amazing and on screen play is smooth with low latency enabled on the projector.I bought a tv tuner box and this thing is amazing for watching any sports game on the big screen.I project onto a 110” screen and have a semi lit basement unless it’s night time. Beautiful picture night or day!

### ⭐⭐⭐⭐⭐ Fantastic TV Replacement – A True Home Theater Experience!

The 4K resolution is stunning, with sharp details and vibrant colors that make movies, shows, and games look absolutely incredible.The 4000 lumens brightness ensures a clear picture even during the day, and it works beautifully in my living room without needing blackout curtains. Setting it up was quick and easy, and the range of connectivity options means I can plug in all my devices without hassle.The size and clarity of the image make it feel like I’m in a theater every time I use it. Whether you’re watching a blockbuster or just streaming your favorite show, this projector delivers. If you're looking to ditch your TV and upgrade to something truly cinematic, this is the way to go!

### ⭐⭐⭐⭐ Solid 4K HDR Projector for the $$
*by  on Reviewed in the United States February 14, 2024*

When I first hooked up this projector using my existing HDMI cable it looked bad, worse than my 7 yr old projector. I ordered a new 4K HDMI cable and laboriously ran a new 30 ft line to my receiver and lo and behold it was everything I had hoped it could be. Super sharp/crisp/good color saturation and the fan runs quiet. I'm still working out some kinks on the keystone, I docked it 1 star as it's not the most intuitive to adjust to fine tune the corners. I'm using a 165" elite screen at about 14 ft distance hooked up to an AppleTV 4k, overall this projector is really nice, especially for $1k and look forward to watching more movies/sports in 4K.
