Viewsonic PX748-4K Review – 4K UHD Projector

The Viewsonic PX748-4K 4,000-lumen lamp has the ability to compete with any indoor ambient light level without sacrificing image clarity or saturation. Since it employs a standard-throw lens, you will still need a room with a sizable amount of space if you want a big screen. You’ll need about 9 feet between the wall and the screen for a 100″ image. However, most living rooms, game rooms, and other places may accommodate it, and it doesn’t at the very least require a specialised, light-controlled home theatre room.

Most users would choose to ceiling-mount the PX748 due to its long throw, and it is light enough and small enough to fit common projector mounts. With a 1.3x zoom and 2D keystone correction, along with a warping tool to create square, precise photographs even on irregular surfaces, its image editing tools are quite basic. With no lens shift or other features to correct alignment issues, your projector mount location will still need to be exact, but it is quite flexible for individuals with intricate viewing regions or weirdly shaped viewing areas.

The PX748’s internal 10-watt speaker is adequate, if not outstanding. With a sound quality similar to what you’d expect from most flatscreen TVs, it is loud and clear enough to be used for watching TV or playing games without the need for additional sound sources. In order to get an immersive soundscape or surround sound experience—which this projector’s speakers can’t provide—the majority of home theatre consumers will want to link it with a soundbar or sound system.

It is 22 cm long, 31 cm wide, and less than 3 kilogrammes in weight. This is amazingly small and ought to fit in even the smallest spots in your apartment. Though not an extremely short projector, this one is. You’ll need to plan for a projection, which could come from your ceiling or a tiny table. With this projector, you can make a 100-inch picture from just 2.5 metres away thanks to its short throw distance. Such a projector was more typical in boardrooms a few years ago. All that has changed due to the pandemic. It’s encouraging to see companies like ViewSonic adapt to this market transition by adding useful features that make their products simpler to use.

Picture Quality

Picture Quality

The PX748 excels in this area the most. For clear, real 4K resolution, a DLP display with XPR technology is used. Its support for HLG and HDR technologies improves this clarity and precision. Even when you’re viewing sports or other fast-paced entertainment, clarity is maintained since the frame refresh rate, at 240Hz, is comparable to the best home theatre systems.

On the PX748 as well, ViewSonic’s own SuperColor technology is utilised. This gives it a wider colour spectrum than other projectors of a comparable price and allows it to maintain the same brilliant colours in any lighting condition.

However, it does have certain drawbacks. In contemporary home entertainment setups, its absence of wireless connectivity could be problematic, and its longer throw distance restricts its use in smaller places. But for a lot of users, its responsiveness and image quality make it a very appealing choice.

    Not quite the right color

    By Uttam Mishra 

    Overall Experience:

    This projector provides decent contrast and brightness. Maybe it’s just me, but I have trouble getting some of the colors to look right. If you want to use it with a Firestick, you must use both controls and not Arc. Make sure to unplug the power from the wall before going on vacation because if there is a power outage and it is restored, the projector will turn on and consume lamp hours.
