Viewsonic CPB701-4K Review – The Home Projector

You’re not the only one who is debating between a home projector and a big-screen TV. There has been a significant surge in consumer interest in home projectors, as we have been starting for more than a year. The epidemic has transformed a sector that was mostly an office boardroom phenomenon into a massive retail consumer potential. The crossover to include additional functionality that we’ve come to anticipate in smart TVs is still being made by many makers for this reason. In addition to providing a wide screen for your den, ViewSonic’s CPB701-4K claims to be a genuine 4K projector choice with a price advantage over modern 65 to 75-inch 4K TVs.

A nice option for upgrading to 4K is the CPB701-4K, a 3,500 ANSI Lumens high brightness 4K home projector. Enjoy stunning images with HDR/HLG compatibility and real 4K clarity, or take your gaming to the next level with 4.2ms Ultra-Fast Input and 240Hz refresh rate. With strong warping, auto V keystone, H/V keystone, and 4-corner adjustment, it is now simpler than ever to project a huge screen up to 300″ on any surface. Its 20,000-hour bulb life and energy efficiency make it even more affordable to purchase than a normal light projector.

Our Verdict


The CPB701-4K, a 3,500 ANSI Lumens high brightness 4K home projector, is an excellent upgrade choice. With true 4K clarity and HDR/HLG support, enjoy breathtaking visuals, or step up your gameplay with 4.2ms Ultra-Fast Input and 240Hz refresh rate.

The Viewsonic CPB701-4K projector resembles the one you may find in the boardroom of your workplace. Though it is lightweight—less than 3 kg—and portable. However, you probably won’t do that, especially if you have young children who enjoy practising their fastest sprinting techniques indoors. I was able to project onto a screen that was around 90 inches wide and 10 feet away. Given a large enough wall and a projection distance of 36 feet, you can extend this all the way to 300 inches. For this projection, I put the projector on a small table, but most homeowners should really choose a ceiling installation.

Picture Quality

Sound Quality

The projector, which is based on a single 1,920 by 1,200 DLP chip, utilises just 1,920 by 1,080 of the chip’s total 1,920 by 1,080 pixels, limiting its native resolution to 1080p. Due in part to its RBGCYW (red-blue-green-cyan-yellow-white) colour wheel, it has a high brightness rating. The picture is better equipped to withstand ambient light thanks to the white section, which allows more light to enter the lens than in a projector without one. Sadly, it frequently reduces colour accuracy. The cyan and yellow panels increase some colour accuracy, which helps to counteract that tendency. However, take notice that DLP projectors are made for viewing in a dimly lit space.

The Viewsonic CPB701-4K projector is similar to the one in the boardroom at your place of business. Despite being portable and less than 3 kg in weight. Even if you have young children that prefer practising their quickest sprinting methods indoors, you generally won’t do it. I was able to project onto a roughly 90-inch-wide screen that was 10 feet distant. You can stretch this all the way to 300 inches with a big enough wall and a projection distance of 36 feet.

However, the CPB701 excels in terms of reliable picture quality, especially during the day, and has sufficient connections for connecting casting devices or external media devices. Solid lamp life of up to 20,000 hours checks the box for durability. With all of this in mind, the Viewsonic CPB701-4K is an appealing choice if you’re looking for a 4K home projector.

    fantastic projector but I didn't like fans noise

    By Gaurav Chopra 

    Overall Experience:

    The fans are exceedingly noisy, and to make matters worse, there was an unpleasant high-pitched whine (coil whine?). Not certain if it was a problem with the one I had, but I had to return the item in the end. The image itself was excellent and was compatible with Xbox One X.
