Canon LV-8310

Throw (4.70)

The relationship between the screen-projector distance and the size of the image on the screen is a critical factor in choosing a projector. So, we calculate the range of distances from the screen that every projector has to be in order to fill screens of a certain size. If you want the projector to work with a certain size of screen, you will need to be able to mount it within the ranges indicated below. The LV-8310 includes a 1.2x zoom lens that provides a decent amount of flexibility here, which makes it more flexible than many in terms of where it can be mounted.

	Canon LV-8310 Required Distance for Screen Size
	64-inch screen	80-inch screen	100-inch screen	120-inch screen	140-inch screen
Wide Angle	4ft 8in	5ft 10in	7ft 4in	8ft 10in	10ft 3in
Telephoto	5ft 4in	6ft 9in	8ft 5in	10ft 1in	11ft 9in

Screen Brightness

The further the projector is from the screen, the dimmer the image is going to be. Below are our calculations for how bright the image is likely to be on various sizes of screens when running in the Presentation mode.

	Canon LV-8310 Projector brightness
64-inch screen	2270 lux
80-inch screen	1453 lux
100-inch screen	930 lux
120-inch screen	646 lux
140-inch screen	474 lux

Projectors like the LV-8310 have to overcome the ambient light in the room they are showing in, and this becomes increasingly difficult as the amount of incidental light increases. Below are our predictions for if this projector will be suitable for use with various sizes of screens at different incidental light levels, ranging from near darkness to a well-lit office. The bottom line is that this projector should be able to handle up to a 140-inch screen in a dark or simply lit room, but it doesn’t have the power to cut through moderate lighting on a screen bigger than 100 inches, or anything bigger than a 64-inch screen in a brightly lit room. So, if you are using this in a typical office or conference room, you’ll need to either dim the lights or use a smaller screen if you want your presentation to stand out.

Screen Materials

You don’t always get a nice screen to work with, so we test how well the projector does at projecting onto other surfaces, such as wood paneling and a couple of types of paint. We found that the LV-8310 did pretty well here: the image is still visible on all of the surfaces, and the Screen Color modes provide a good amount of customization. There are 10 different settings for different types of screen (whiteboard, greenboard, etc) and different colors of paint (light yellow, pink, sky blue, etc), which should provide enough options to find a setting that at least partially corrects for the surface color.

Optical Issues (8.75)

We noticed a few minor issues with the optics of the LV-8310. The right side of the image was slightly softer than the center and the left, making edges and fine details a little less defined. This seemed to be caused by a slight flaring effect; on close examination, we found that isolated pixels on the right side of the screen had a slight flare to them that bled into the adjacent pixels, softening the overall image.

Video Processing (2.00)

Only one video processing option is available: the Auto PC mode that analyzes and corrects signals coming in on the VGA port.

Formats (6.00)

The LV-8310 is a WXGA projector, which means it has a resolution of 1280 by 800 pixels. It can display any computer resolution lower than this, and can also display larger resolutions by scaling them down to fit. It can also handle video signals in any one of a range of resolutions, from standard definition video up to 1080i. It cannot, however, handle a 1080p signal, which is the same 1920 by 1080 pixel resolution as 1080i, but with 60 frames a second of video instead of 30.
