ViewSonic X10-4KE Home Entertainment Projector Review

Posted on February 28, 2020 by Art Feierman

The ViewSonic X10-4KE takes the big screen experience, makes it portable, and gives it a handle. Add to that the 4K UHD resolution (3840 x 2160), short throw design and smart TV capabilities, you’ve got a highly versatile, portable home theater. The X10-4KE combines the very best of home entertainment and packages it into a super compact form, measuring just 10.3” wide, 10.7” deep, 6.5” tall, and weighing 9lbs.

This full review of the ViewSonic X10-4KE takes an in depth look at the projector’s features and benefits, and puts its manufacturer claims to the test. Our reviews check the performance of the projector and report on the strengths and shortcomings we find during our process. You’ll get an honest, third-party account of the X10-4KE, and by the end of the review, you should have a pretty clear idea about whether or not this is the projector for you. There is no such thing as “the best” projector – only the projector that’s right for you, that best suits your needs.

Let’s get started.

The ViewSonic X10-4KE – At A Glance

Immediately, I was struck by the projector’s design, for which it actually won the iF Design Award. I’ve been creating graphics involving the ViewSonic X10-4KE for months for Projector Reviews, so I am intimately acquainted with all angles of the projector, and I was quite eager to get this little guy in for review. Occasionally, I get thrown an exciting home entertainment projector to break up the steady stream of classroom projectors I usually review, and the ViewSonic X10-4KE did not disappoint.

This is a compact projector made even more portable by its handle. The projector is a sleek, matte gray with brown leather accents, making the X10-4KE look retro with a modern touch. That handle’s top is lined with a classy strip of leather, its color reminiscent of a briefcase from the late 60s. Even cooler, the inputs are hidden by a leather door that flaps down to reveal a simple connector panel that has everything you require for your home entertainment needs.

The ViewSonic X10-4KE has a 2,400 lumen claim, which is bright enough for most living rooms, media rooms, and family rooms with decent lighting control. This is not a bright room projector, but it is capable of handling a modest amount of ambient light without the picture being severely washed out. It’s also not a gaming projector – its input lag is far too high for most gamers, save for the super casual gamer or families playing Nintendo Switch. More on gaming later in the review.

The ViewSonic X10-4KE is capable of really good color.

The projector has 4K UHD resolution and an RGBB LED light engine. That light engine will last up to 30,000 hours. That means next to no maintenance on the X10-4KE, as compared to lamp based projectors, whose lamps last between 3,000 and 8,000 hours. It can project an image of up to 120” – this is the preferred size of many home theater enthusiasts. I have a 92” screen, but think I would prefer 100” for my space. Though, I wouldn’t say no to that 120”.

Since this is a super portable projector, you may find yourself taking it outside for a movie night when the weather warms up! This ViewSonic has built-in Harman Kardon speakers for great onboard sound, or you can hook up your favorite Bluetooth speaker or sound bar. Since I’m getting into the projector’s special features, let’s take a look at the X10-4KE’s highlights, then dive deeper into the individual features on the next page.
