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. There are two HDMI and one USB-C source for content, as well as a PC input. And no, this does not have a built-in operating system that enables app-based streaming of content. I meant that this was more traditional because of that. For iPhone and iPad, users need to buy an Apple-authorized Lightning-to-HDMI adapter for content display via the HDMI port.
The PX748 excels in this area. For clear, genuine 4K resolution, it uses a DLP display with XPR technology. Its support for HLG and HDR technology improves this clarity and accuracy. While watching sports or other fast-paced content, clarity is maintained because the frame refresh rate, at 240Hz, is comparable to the best in the home theater industry. To determine the Throw Distance for where you should place your projector in the room, enter an image diagonal measurement number in the Image SizeAs 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. 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. The PX748-4K is a 4,000 ANSI Lumens 4K home projector that shines in value and brightness and delivers pixel-perfect visuals in true 4K clarity with HDR/HLG support. Experience a whole new level of gaming with 4.2ms Ultra-Fast Input, a 240Hz refresh rate, and USB Type-C connectivity for direct streaming from Nintendo® Switch. Set up faster and easier than ever before with powerful warping, auto V keystone, H/V keystone, and 1.3x optical zoom, capable of creating a screen of up to 300” on any surface. Adding on to that is the LAN control capability compatible with home automation systems and 12V trigger output, making the PX748-4K a perfect addition to your smart home. 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.
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. Most products are shipped as standard on a next working day delivery. Delivery can be anytime between 7.30am and 6.00pm and will require a signature upon delivery.
Using the Zoom Range Slider
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 properly To ensure you view how you want, there are pre-set modes for video games and movies as well as various aspect ratios. There is also the option to fit the image to every corner of the frame despite the automatic keystone adjustments. This exercise was somewhat difficult for me, though. Auto keystone adjustment always resulted in an image that was much smaller than the full throw and inside the frame. Highlights
