ViewSonic X10-4KE True 4K UHD Short Throw LED projector review


The ViewSonic X10-4KE is a 4K UHD (3840×2160) resolution home entertainment projector with an LED light engine. It measures 10.3” wide, 10.7” deep, 6.5” tall, and weighing 9lbs, and comes equipped with a sturdy handle that allows you to carry it easily from room to room, or out back for an outdoor movie night.


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 X10-4KE has two HDMI inputs for connecting digital high-definition sources such as Blu-ray players and HD cable/satellite boxes, plus a USB-C and two USB-A ports. Its HDMI inputs are 3D-capable for viewing 3D Blu-ray discs with other compatible equipment, which is available separately. When connected to your LAN, the projector can be controlled with just your voice through your Amazon Alexa or Google Assistant devices. The X10-4KE includes a USB-C cable, a Wi-Fi adapter, and an IR remote control for added convenience.


This projectors lens is positioned on the front of the projector, in the center, behind a protective sheet of glass. To the left of the lens, when facing the front, are two sensors – one for IR, and one for Auto Focus. Also on the front, below the lens casing, is the Eye Protection Sensor, which senses when someone moves in front of the projector, and shuts off the light so as to protect their eyes. This is particularly useful if you have a curious toddler, dog, or cat roaming about the house.

Throw distance

The X10-4KE’s short-throw lens has a throw distance of 1.6 – 11.5 feet, allowing for an image size ranging from 30 to 200 inches. Since the lens has no zoom capability, you’ll need to situate the X10-4KE at a specific, fixed distance from the projection surface. While the X10-4KE is 4K- and HDR10-capable, ViewSonic doesn’t list a P3 color space spec, though it does cite Rec. 709 color coverage at 125 percent.


On the audio side, the X10-4KE’s built-in speakers were designed by Harman Kardon and are Bluetooth-capable for music streaming. An included Wi-Fi dongle lets you set the projector up to stream from Netflix and YouTube among other apps that can be downloaded directly from the Aptoide app store.


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.

DLP chip

ViewSonic designed its flagship portable with a dark gray case and leather carrying handle that give it a sleek and substantial look and feel. The projector features a 0.47-inch Texas Instruments DLP chip that uses XPR tech to achieve 4K resolution via pixel-shifting.

Projector lifespan

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. 

How to setup ViewSonic X10-4KE True 4K UHD Short Throw LED projector?

Filling up a 92-inch diagonal, 1.1 gain Stewart Filmscreen Cima screen in my home theater with an image from the X10-4KE required placing the projector on a low table at a fixed 65-inch distance from the screen. Because the projector has no vertical or horizontal lens shift adjustments, the center of the lens needs to be aligned exactly perpendicular with the screen’s bottom edge to avoid image keystoning. With its Auto Vertical Keystone and Auto Focus and features enabled, the X10-4KE can automatically align and focus the image after you’ve roughed in placement. Auto Focus worked well, but I found that making keystone adjustments manually delivered better results.

ViewSonic X10-4KE True 4K UHD Short Throw LED projector Performance review

Overall, the quality of the projector is good. The unit offers the basic features and is the cheapest of the 4K projectors in the market right now. You definitely get what you pay for with this unit. I use it as the focal point of my entertainment center, with a Roku and PS4. I also have a receiver that allows 4K pass-through, so the 4K content from roku/ps4 is actually being shown in 4k on the projector. If you are passing audio to a unit that isn’t 4K compatible, you will not be able to see 4K quality.
