Changhong V8S
4K UHD Laser UST Projector
With 2500 ANSI lumens and 8 points keystone adjustment, V8S is the 1st new UST added TO our 2021 product line.
4K UHD Experience at Home
V8S offers the native resolution of 4K UHD. Powered by its 2500ANSI lumens brightness, stunning, vivid image is to be delivered at your home theatre, even under the ambient light conditions.
MEMC
MEMC is a frame interpolation technique developed to enhance the quality and smoothness of the video. The process artificially adds additional frames between original frames.
MEMC is important for high movement pictures such as live sport program, with the help of 3rd generation MEMC, you will no longer so dragging /blur on the images.
HDR 10
HDR10 doubles the perceived image brightness along with a increase image contrast (comparison of the light reflected from an all-white image and an all-black image).
With HDR10, user’s won’t suffer from missing details and see more depth in the colour.
8 Points Keystone
With up to 8 points keystone adjustment, you can easily obtain a perfect image on screen even when the projector's position is not that perfect.
This is extremely helpful for UST projectors like V8S because any slight misalignment of the projector's position can cause misshaped image due to the short distance between the projector and the screen.
The True Colour
BT.709 is the worldwide HDTV standard for colour space to ensure accurate colour to be displayed.
V8S goes beyond the industrial standard in terms of colour space. V8S covers 130% of the BT.709 colour space so you can enjoy the most accurate and vivid picture in your living room.
Advanced UHD Optimisation
To deliver the finest image, V8S employs the 3D-NDR and MPEG noise reduction technology.
3D-DNR reduces unwanted picture noise, on the other hand the feature compensates for image distortion due to colour blending errors by extrapolating and removing even the smallest defective pixels.
MPEG Noise Reduction feature improves the quality of pictures by reducing the block noise and mosquito noise without compromising the picture resolution.
The UST At Its Best
V8S is a UST (Ultra-Short Throw) projector with the throw ratio of 0.21:1. It projects 100" screen at the distance of 19.5cm from the screen.
Because the projector is so close to the screen and it projects from the bottom to the top, it can efficiently reject ambient light coming from other directions so you won't suffer from washed out pictures. Also, because the light only travel an ultra short distance, you will get a much brighter image when compared with long-throw projectors.
