Product Information

ViewSonic’s proprietary SuperColor™ Technology displays a wide color range, ensuring that users enjoy a true-to-life color performance in both bright and dark environments without sacrificing image quality. To determine the Image Size (screen size) enter a distance measurement number in the Throw Distance value box and hit the Enter It shouldn’t come as a surprise to learn that the recent influx of budget level 4K DLP models are all based on the same underpinnings and chassis, with just software tweaks and manufacturer specific items added. It keeps the costs down and allows development and R&D to be spread out, so no one company has to bear the weight of these costs. As such, most models have a similar looking body layout and the menus, while having different colours and naming conventions from each other, are also the same basic design and interface. The 4,000-lumen lamp of the ViewSonic PX748 has the power to compete with any indoor ambient light level, without losing clarity or saturation in the image. Now you will still need a fairly large space to get a big screen since it uses a standard-throw lens. For a 100” image, you’ll need around 9 feet of distance between the wall and screen. That’s doable in most living rooms, game rooms, and other spaces, however, and it at the least doesn’t need a dedicated, light-controlled home theater space. Scale up the excitement with a screen size easily made larger than a TV, even in limited space. Immerse yourself in 100” of entertainment from only 2.5 m away.

Using the Zoom Range SliderThe latest SuperEco+ mode technology greatly extends the lamp life of the projector from 15,000 hours to 20,000 hours – meaning 4 hours a day for more than 13 years – saving you maintenance cost and effort.

It is also made from tough plastic and portable so it can be transported to a friend’s house for some gaming, or watching big sporting events on the side of a house or a wall at parties. It is not designed for home cinema use where critical viewing and the image quality is key. It doesn’t pretend to be that kind of projector and if that is what you are looking for, you need to look elsewhere and at a much higher price point. If your selected projector has a Zoom Lens then the projector's Throw Distance or Image Size can be finely adjusted by moving the

Be it on the side table in the living room, bedroom or any other location you like, the projector can provide perfectly shaped images from any angle with comprehensive H/V keystone and 4 corner adjustment capabilities. The auto V keystone further frees you from manual adjustments no matter how you tilt the projector, up or down. There are also some video processing features on the ViewSonic and these are found under the MoviePro section in the advanced menu and give the options to enhance skin tone, colour and resolution that are basic colour and sharpness tweaks. There is no frame interpolation mode on the PX747-4K.calculator, you will see dimension lines that will tell you the height, width, and diagonal measurements of your image. Calculating a Throw Distance when you know the IMAGE SIZE As we covered within the introduction, the ViewSonic PX747-4K uses the latest TI chipset to produce an image, which fools the eye into seeing 8.3 million pixels on the screen. It does this by flashing parts of the image four times to create the illusion of resolution. It’s clever technology that ultimately saves money when compared to trying to produce a native 4K DLP chip. As such, the ViewSonic PX747-4K will accept 4K content from external sources such as your UHD Blu-ray player and a streaming device such as an Apple TV 4K box or similar. Of course, it will also accept 4K games from appropriate consoles. That also means that the Viewsonic will take HDR10 signals and it will tone map these to the projectors capabilities. Just don’t expect HDR images as you know them from flat-panel TVs. The colour wheel is an RGBW unit and there is no mention of colour space coverage or if it has any special coatings to help it reach Rec.709 coverage. There is certainly going to be no wide colour gamut coverage here at this price point and with this technology.

fit your image onto a screen you need a projection calculator tool or throw chart to tell you the image size dimensions at the corresponding away from the screen or wall, the image will get bigger, and as you push the projector closer to the screen or wall the image will be smaller. To properlyThis is where the PX748 is the most impressive. It uses a DLP display with XPR technology for sharp, true 4K resolution. This sharpness and accuracy is enhanced by its support for HLG and HDR technology. The frame refresh rate is on par with the top performers in the home theater space, at 240Hz, so that clarity is maintained even when you’re watching sports or other fast-paced content. It's small - This is good because I have a low ceiling where this is installed and need people to be able to walk under it. My setup is in a light control environment, from 6 flood lights, to hit your toe against the table kind of dark. so, I can turn on some lights and do other things while watching if needed, Like I little gaming, Total darkness not necessary for it. And still have a great picture.
