ViewSonic PX748-4K projector review: one for specialists

After the wave of ultra shot UHD projectors bringing big theaters home with really wide picture and sound, I had to try something a little more conventional. The ViewSonic PX748-4K projector is exactly that. A projector that is more conventional in its behavior but contemporary in terms of capabilities.

The ViewSonic PX748-4K has a traditional design with a lens on the front and controls on the top. There are two rings with the lens, one for zooming in and out and the other for focusing. It is not very big and can be moved easily. It also comes with a backlit remote that lets you control everyone with ease.

While I placed it on a table about four feet from the wall to get a 40 inch picture, this is the kind of projector that has to go on a stand across the room to get a giant picture. which uses 4K projection to its full capacity. It can easily go up to 80 inches while still being sharp. Unfortunately, I didn’t have the walls for it.

Besides a PC input, there are two HDMI sources and a USB-C source for content. And no, it doesn’t come with a built-in operating system that lets you stream content through apps. That’s why I wanted to say it was more conventional.

But there are also advanced technologies at work here. This projector is capable of super-fast 4.2ms input and 240Hz refresh rate, making it ideal for gamers who want to play at a high level. I tried projecting mobile games using the USB-C cable from a OnePlus 9 Pro and the experience was pretty good.

At 4000 ANSI Lumens, this is the brightest projector I have ever tested. So bright that it can be projected outside in the light of October daylight in Delhi. This is not the only aspect that you can adjust. I loved the multiple color temperature levels that allow you to get the perfect picture, like when you watch a series like Earth at Night on Apple TV.

There are preset modes for games and movies and different aspect ratios to make sure you view the way you want. In addition, despite the automatic keystone distortion adjustments, it is possible to adapt the image to each corner of the frame. However, I found this exercise a bit heavy. With the automatic keystone distortion adjustment, the image always ended up inside the frame and much smaller than the full projection.

While the image quality is good, you will notice that it takes a second to get to the right setting and you may also have to push it sometimes. Additionally, the audio quality is just passable and you will need external speakers to fully enjoy the big screen experience.
Another interesting feature is the multiplicity of eco mode options which allow you to save energy and lamp life. In addition, the projector goes into standby when it is idle.

At Rs 2,70,000, the ViewSonic PX748-4K is a premium option that will appeal to specific segments such as game and movie enthusiasts. However, at this price, ViewSonic could have offered better software and audio quality.
