## Description

With incredible Ultra HD resolution, HDR/HLG support, and a high brightness of 4,000 ANSI lumens, the ViewSonic PX748-4K projector delivers stunning home entertainment around the clock: day or night, in bright rooms or dark. With an ultra-low 4.2ms input lag, 240Hz refresh rate, and USB-C connectivity for direct streaming from gaming consoles such as the Nintendo® Switch, this projector provides a whole new level of gaming. Set-up is a breeze too: 1.3x optical zoom, warping capabilities, and H/V keystoning allow for more flexible mounting and easy installation with screen sizes up to 300” on nearly any surface. What’s more, LAN control compatibility and a 12V trigger make this projector a perfect addition to any smart home.

Review: Great picture and worth it, just not great speakers. - Very good, even with sunlight. Does take a while to turn on but that’s normal. I do wish it had Bluetooth for exterior speakers as the speakers are not very good.
Review: Best Bang For Your Buck - Quality and Cost - 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!

### ⭐⭐⭐⭐ Great purchase with minor limitations
*by M***R on September 29, 2025*

I bought this projector for a set up in the backyard for movies and while it is great crisp in color and projects. Well it is missing some of the adjustability to smaller screen sizes on further distance quality and contrasts are amazing. Would definitely recommend to anybody that needs a projector within this price range.
