The ViewSonic PX747-4K is the bright room version of the PX727-4K, a 4K UHD projector intended for use in the home theater. Also a 4K UHD projector, the 3,500 lumen PX747-4K will be at home in any living room, family room, media room, or bedroom that cannot be fully darkened, and therefore will always have some degree of ambient light. Now, Art reports that the projector did not quite hit its mark, coming in at around 3,200 in its brightest mode – but that’s still plenty to cut through some pretty serious ambient light.
This is a DLP projector with an RGBW color wheel, rather than the RGBRGB type found on the PX727-4K. Generally speaking, that RGBRGB color wheel is more of a home theater type wheel, whereas the RGBW is found more often on home entertainment and business/education projectors. The “W” in RGBW refers to a clear slice that allows a lot of light to pass through, improving the amount of white lumens the projector is capable of outputting, resulting in an ultimately brighter image.
The ViewSonic PX747-4K has an impressive lamp life of up to 15,000 hours – but that’s with SuperEco on. With it off, you can probably expect it air on the higher side of the norm for lamp based projectors. Either way, the projector will give you a lot of bang for your buck – especially at the reduced price – and have you enjoying many thousands of hours of entertainment before you will need to switch out the lamp.
It has a 12,000:1 contrast ratio, which is the same as its home theater twin, but you can expect the ViewSonic PX727-4K to have better black level performance than the brighter PX747-4K. No matter – the ViewSonic PX747-4K will undoubtedly have better dark shadow detail, which means you will be able to see details in dark scenes better than you will on the PX727-4K
Like most ViewSonic projectors, the PX747-4K is compact and portable. Weighing less than 10 pounds, this ViewSonic measures just 13.1” wide, 5.3” tall, and 10.3” deep.
