The PX748’s 10-watt speaker is adequate, if not exceptional. ![]() With no lens shift or other features to correct alignment issues, your projector mount placement will still need to be exact, but it is relatively flexible for those with complicated viewing areas or oddly shaped viewing areas. With a 1.3x zoom and 2D keystone correction, along with a warping tool to get square, accurate images even on irregular surfaces, its image adjustment features are fairly standard. Most users will want to ceiling-mount the PX748 due to its long throw, and it is lightweight and small enough to fit standard projector mounts. However, most living rooms, game rooms, and other spaces can accommodate that, and it doesn’t at the very least require a dedicated, light-controlled home theater room. You’ll need about 9 feet between the wall and the screen to accommodate a 100″ image. In light of the fact that it makes use of a standard-throw lens, you will still require a sizeable space if you want a big screen. The ViewSonic PX748’s 4,000-lumen lamp has the capability to compete with any indoor ambient light level without sacrificing image clarity or saturation.

The Delhi daylight in October is so bright that it can be projected outside. This is the brightest projector I have ever tested, putting out 4000 ANSI Lumens. It worked well when I tried to project some mobile games using the USB-C cable from a OnePlus 9 Pro. For gamers who want to play at a high level, this projector is the best choice because of its 4.2ms ultra-fast input and 240Hz refresh rate. However, cutting edge technology is also in use here.
