The ViewSonic X10-4KE (listed for $2,399 however typically out there for as little as half that) is an impressively small 4K UHD (3,840-by-2,160) short-throw projector. Like its predecessor, the ViewSonic X10-4K, and the LG Cinebeam HU70LA, this handy machine gives HDR10 help, a solid-state mild supply, and a reasonably mild weight—although at 9 kilos, it is extra luggable than portable. Niceties corresponding to a dependable auto-focus make it as simple to arrange as a TV. Most significantly, it delivers respectable colour accuracy, distinction, and shadow element straight out of the field.
Setup Is a Snap
Like most DLP 4K projectors, the X10-4KE makes use of TI’s XPR fast-switch pixel shifting to get 3,840 by 2160 pixels on display screen from a 1080p chip. It pairs the chip with a red-green-blue-blue (RGBB) LED mild supply, including the second blue diode for increased brightness and to assist enhance colour accuracy.
Setup is easy. Level the projector at your display screen, plug within the energy twine, and connect with a video supply. The short-throw lens has no optical zoom, so you must transfer the projector to regulate picture measurement, however the auto-focus works effectively sufficient that you do not have to fiddle with it.
The X10-4K measures 6.5 by 10.3 by 10.7 inches (HWD), which supplies it room on the again for all of the connectors you are ever prone to want, together with two HDMI 2.0 ports for video sources and PCs and one USB-C port for PCs and cell units. There’s additionally an Ethernet port for wired community connection and a bundled Wi-Fi dongle to attach wirelessly to your community for streaming or join on to PCs and cell units for display screen mirroring.
Good options come courtesy of the Android OS. By the settings, you’ll be able to entry a hyperlink to the Aptoide retailer for downloading streaming apps, hyperlinks for putting in Alexa and Google Assistant voice management, and an app that can flip your cell units into further remotes for the projector.
By default, body interpolation (FI) is enabled. It smooths movement and lots of think about it an enhancement for dwell and recorded video. Nevertheless, it additionally provides a digital video or “cleaning soap opera” impact to filmed materials. For those who don’t love FI, it is simple to show off.
The onboard stereo audio earns numerous factors. The 2 8-watt audio system ship sufficient quantity for a big household room together with increased high quality than most big-screen TVs. You possibly can even use the projector as a Bluetooth speaker for different units. If you’d like nonetheless higher sound high quality from an exterior audio system, there are analog and digital audio out ports in addition to help for Bluetooth output.
Avid gamers ought to word that my Bodnar meter measured a 76ms enter lag at 1080p 60Hz with FI off, which is a bit of sluggish even for informal gaming. That is too unhealthy, because the portability options—together with a panel that flips as much as cowl the ports when you’re transferring the projector—are in any other case gaming-friendly.
For Finest Colour, Some Fiddling Is Wanted
The X10-4KE’s 4 predefined image modes—Brightest, Gaming, Film, and TV—all delivered extremely watchable pictures in my checks, thanks largely to paint accuracy that diversified from a minimum of satisfactory to simply greater than acceptable by most individuals’s requirements. Even the aptly named Brightest mode confirmed hardly any of the inexperienced bias that is typical of the brightest modes in most projectors.
TV mode had the perfect distinction—verging on overdone with some pictures—however the least correct colour. Film and Gaming modes had the perfect colour accuracy. Not one of the modes delivered top-tier shadow element, and none delivered a great sense of three-dimensionality; Gaming mode did the perfect job on this rating, retaining a lot of the shadow element even in essentially the most difficult darkish scenes. It additionally had the perfect total stability of colour accuracy, distinction, and shadow element, and was virtually as brilliant as Brightest mode, a mixture that makes Gaming my most well-liked alternative.
For 4K HDR enter, the X10-4KE has HDR equivalents of the 4 SDR modes. As with most HDR projectors, it is advisable to modify an HDR setting—appropriately recognized within the menus as Electro-Optical Switch Perform (EOTF) as an alternative of the extra frequent HDR Brightness—to accommodate variations from one film to a different. In Film mode, with the proper adjustment, brightly lit scenes had properly saturated colour and good distinction, whereas darkish scenes had maybe a contact higher shadow element than the SDR variations of the identical motion pictures. Nevertheless, I didn’t see a big distinction between SDR and HDR in most points of picture high quality. The obvious is the additional element that comes from viewing 4K UHD content material at 4K UHD, slightly than 1080p content material upscaled to 4K UHD.
The X10-4KE additionally handles Full HD 3D properly, utilizing DLP-Hyperlink glasses. There are 3D variations of all 4 image modes. I did not see any crosstalk in my checks, and 3D-related movement artifacts had been typical for latest projectors. Picture brightness in 3D is increased relative to the 2D modes than with most projectors.
ViewSonic touts a 2,400–LED lumen score for the X10-4KE’s brightness. That is increased than the 1,000–ANSI lumen score as a result of LEDs produce extra saturated colour than lamp-based projectors, and with equal measured brightness, extra saturated colour is typically perceived as being brighter. Nevertheless, I believe that score oversells the X10-4KE. My subjective judgment is that the perceived brightness is a contact decrease than what I anticipate from 1,000 ANSI lumens.
In a darkish room, utilizing the Society of Movement Image and Tv Engineers (SMPTE) suggestions, 1,000 lumens must be sufficient for a 150-inch diagonal, 1.0-gain, 16:9 display screen. In reasonably brilliant ambient mild, it must be sufficient for an 85-inch display screen. Utilizing Gaming mode, I discovered the X10-4KE brilliant sufficient for a 90-inch, 1.0 achieve display screen at midnight and an 80-inch display screen in low to reasonable ambient mild at night time in a household room. For daytime use in a household room, nevertheless, even Brightest mode was washed out on an 80-inch display screen. You may want to maneuver the projector nearer to the display screen for a smaller, brighter picture that may survive a well-lit room.
As with every single chip projector, rainbow artifacts (red-green-blue flashes) are a possible challenge. I noticed extra with the X10-4KE than with most LED fashions, however they had been fleeting sufficient that should you aren’t delicate to them, it’s possible you’ll not see any. For those who’re involved in regards to the challenge, purchase from a seller you’ll be able to return the projector to with out a price, so you’ll be able to check it out for your self.
4K to Go
If you’d like a reasonably moveable 4K projector, the X10-4KE is among the few selections. Laser 4K projectors are heavier and dearer. Loads of lamp-based fashions, such because the BenQ TK850, each value and weigh about the identical or much less, however they are not designed for portability, and most do not embrace streaming, sensible options, or palatable audio system.
One competitor price taking a look at is the LG CineBeam LU70LA, which is LED-based, contains LG’s sensible TV interface and voice instructions, and provides a TV tuner. It even weighs rather less than the X10-4KE. Nevertheless, its onboard audio is not in the identical league. One other chance—should you’re prepared to drop to 1080p native decision slightly than 4K—is the Editors’ Alternative–successful Epson EpiqVision Mini EF12 Smart Streaming Laser Projector, which might settle for 4K UHD enter, helps HDR, is moveable, and prices much less due to the decrease decision.
The X10-4KE’s closest competitor is the marginally inexpensive X10-4K, which it is within the technique of changing. Examine the spec sheets and also you may conclude that they are equivalent. Nevertheless, ViewSonic says that the X10-4KE has a greater IR sensor for extra responsiveness to the distant management and higher auto-focus. That elevated ease of use makes the ViewSonic X10-4KE one of many higher moveable 4K choices.
The Backside Line
The ViewSonic X10-4KE delivers 4K UHD decision, HDR, and built-in streaming, plus a superb audio system. It is semi-portable—name it luggable—and its LED mild supply will final for years.
