Review: Possibly the most impressive piece of tech I've ever ended up buying from desertcart. The picture quality has to be seen to be believed. I tried taking a few shots with my phone, but the image quality of the photos were so misleading in comparison to how it is to actually watch something on the projector that I've ended up not including them. The fan is almost whisper quiet too. The only niggle, if anything, is that the onboard speaker really isn't fit for purpose, but there's plenty of options to connect your own sound system so that doesn't detract much. Review: 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. ## Features - ULTRA FAST INPUT: With <5ms ultra-fast input and hyper-responsive 240Hz refresh rate, you can game with low delay and seamless viewing of fast-moving objects. - 4K UHD RESOLUTION: Delivering impressive visuals in true 4K clarity, as well as supporting HDR and HLG content to produce more dynamic-looking images. - LAN CONTROL CAPABILITY: The PX748-4K comes with LAN control capability that is compatible with a variety of home automation systems (incl.
