To enable 4.2ms Ultra-Fast Input, turn it on in Advanced Settings and make sure the input content is with 240Hz refresh rate. When enabled, the highest resolution supported is 1080p. **The response time stated refers to the reaction time of DMD chip. I wouldn’t hesitate in the least if you’re on the fence and have a room big enough to support the long throw on this projector. 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.

represents the diagonal distance between the top right corner of your image (screen) and the bottom left corner of your image (screen). On The ViewSonic PX747-4K is clearly designed, (like all the 4K DLP budget machines we have tested), to be used in normal living rooms with light coloured walls and ceiling surfaces and some ambient light. 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.Most users would choose to ceiling-mount the PX748 due to its long throw, and it is light enough and small enough to fit common projector mounts. With a 1.3x zoom and 2D keystone correction, along with a warping tool to create square, precise photographs even on irregular surfaces, its image editing tools are quite basic. With no lens shift or other features to correct alignment issues, your projector mount location will still need to be exact, but it is quite flexible for individuals with intricate viewing regions or weirdly shaped viewing areas. the graphical representation of a projector in the middle of the calculator, you will see dimension lines that will tell you the Throw Distance

In addition to the stunningly detailed images that true 4K resolution can offer, the projector also supports HDR and HLG content to produce more dynamic images and bring flat images to life with more displayable information in the darker and brighter parts of a scene. 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.Most users will want to ceiling-mount the PX748 due to its long throw, and it is lightweight and small enough to fit standard projector mounts. With a 1.3x zoom and 2D keystone correction, along with a warping tool to get square, accurate images even on irregular surfaces, its image adjustment features are fairly standard. With no lens shift or other features to correct alignment issues, your projector mount placement will still need to be exact, but it is relatively flexible for those with complicated viewing areas or oddly shaped viewing areas. 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.

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. measurement between the front of the projector lens and the surface of your wall or screen. Using the Zoom Range Slider 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.The Viewsonic PX748-4K 4,000-lumen lamp has the ability to compete with any indoor ambient light level without sacrificing image clarity or saturation. Since it employs a standard-throw lens, you will still need a room with a sizable amount of space if you want a big screen. You’ll need about 9 feet between the wall and the screen for a 100″ image. However, most living rooms, game rooms, and other places may accommodate it, and it doesn’t at the very least require a specialised, light-controlled home theatre room. Say goodbye to motion blur due to input lag. With our 4.2ms Ultra-Fast Input and hyper-responsive 240Hz refresh rate, plus the microsecond-level response time, you can watch with low delay and seamless viewing of fast-moving objects that will bring your sports-viewing-experience to the next level. I put off buying a 4k projector for a while because 1080p on a 200″ screen just wasn’t cutting it. I grew weary of being able to see the scan lines, and my previous projector only produced about 600 lumens, so it could only be used in essentially complete darkness. The 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.
