At the top side we also get the built-in controls which feature a pretty standard layout. There are three LED indicators for power, temperature control and lamp condition while the power button is placed on the left side of the navigation controls. Next to that there are nine buttons for menu, color mode selection, source selection and blank functionality while you can also use the navigation buttons for the keystone correction feature if needed. Brightness Uniformity (Maximum Wide Angle): 66%. Despite the low number, the difference is noticeable only on a 100% white or light-colored image, thanks to the distance between the brightest and least bright measurement points and the gradual change in brightness. These pixel shifting projectors are usually distinguished in two different categories depending the type of pixel shifting technology used. There are projectors that shift the image only in two positions and these use slightly larger chips and are a bit more expensive while those that use the 1920 x 1080 x 4 technology tend to be cheaper without any meaningful loss of quality.
Colors in scenes I'm familiar with, from flesh tones, to the vibrant colors throughout La La Land, to the water, sky, and pastel-colored buildings James Bond passes on his way to his hotel in Casino Royale, looked like I expect them to. And in Hummingbirds Jewelled Messengers, a documentary on South American hummingbirds narrated by David Attenborough, the PX701-4K delivered both stunningly luminescent color for the hummingbirds and breathtaking views of the environment, from foggy rainforest to close up views of hummingbirds feasting on the nectar of vibrant-colored flowers. The PX701-4K was able to deliver vibrant colors of the hummingbirds and surrounding environment in the Hummingbirds: Jeweled Messengers documentary. (Photo Credit: Free Spirit Films) Standard and Gaming modes were also similar to each other, delivering the most neutral color straight out of the box. However, neither was a match for Movie mode for handling the subtle gradations that help give close ups of rounded objects like faces a more three dimensional look. Based on that observation as well as measurements, I chose Movie mode for SDR calibration.

The menus offer up to +/- 40 degree vertical and horizontal keystone correction, corner correction, and even a Warping option, for geometric correction when using a curved surface as a screen.As for the lens that is being used, the PX701-4K has a throw ratio of 1.5-1.65. In terms of size the unit can project a 30″ ~ 300″ diagonal image but as we mentioned above the projector is missing any lens shifting and if you combine that with the relatively small 1.1x zoom you don’t have many options when installing it. UHD/HDR Viewing. The benefits of Dynamic Eco mode apply to HDR viewing as well. Beyond that, I found the Mid EOTF setting worked best for most movies in a dark room and the High setting worked best with ambient light. However, for some movies in a dark room, Mid was a little too dark overall while High was washed out, leaving me with having to decide which compromise I was most comfortable with. This means that we get an image that is hard to distinguish from a native 4K resolution one. Clarity and sharpness was through the roof and even the tinniest of details on surfaces, clothes, materials and surfaces composition were visible. In essence you will not understand that this is not a real 4K unit as is the case with most pixel shifters nowadays.
In real conditions the unit was definitely audible from a distance of 5 feet especially during quiet moments. During busy moments the sound effects would mask the projector’s noise completely but in general we can say that we were not bothered by it and in comparison with some other projectors that come with the same technology the ViewSonic felt slightly quieter. As far as its size the PX701-4K measures 12.3” x 4.3” x 8.7” (312 x 108.37 x 221.8 mm) and weights just 6.17 lbs (2.8 kg) making it one of the smaller 4K projectors we have tested recently. Its small size and low weight combined with its high brightness and on-board audio definitely makes it a very portable solution in the projectors market. Apple's AirPlay technology is used for wireless transmission of content, such as music and videos, from iOS and Mac devices. These can also be receiver devices such as speakers, AV receivers and stereo systems or TVs. Streaming also works from an iOS device to a matching receiver. The protocol developed by Apple can also be licensed by other manufacturers.
Effortless Image Adjustment
I also tested the projector in a family room with lots of windows using an 80-inch 1.0-gain white screen. The calibrated image was easily bright enough to stand up to high hat lights at night. For viewing on a bright day, Gaming mode's higher brightness delivered a watchable, if not particularly impressive, image suitable for watching typical live or recorded video. On the top side, exactly above the lens, we find the controls for the zoom which gives the projector a 1.1x optical zoom and also lens focus. One thing to keep in mind is that the projector is missing any lens shifting so initial placement is made harder by this fact especially if you don’t have enough space to move the projector around. For our real world testing we had connected our PS5 to the projector and used our copy of F1 2021 for a few laps. For the review we used the fidelity mode which outputs at 4K@60Hz. The gameplay was as smooth as butter and as for its responsiveness we could not be any happier from what we saw. Everything registered extremely fast and all our commands would render on screen immediately making this projector ideal for any kind of games you like to play. Motion Performance
