In projector, Should be check firstly 'Quality of Picture' :
There are a lot of different factors that contribute to a quality picture, including projection type, resolution, contrast ratio, refresh rate and brightness. This mini projector offers the LCoS projection type, and the lamp uses triple RGB LEDs. The native resolution for this product is XGA (1024 x 768). This is one of the highest resolutions we saw in all the products we reviewed. Additionally, the unit can support resolutions up to 1280 x 720 and can reach upwards of 30 frames per second. The contrast ratio is also fairly high at 2,000:1. This enables the difference between the light and dark areas to be quite distinct although the blacks will only be as dark as the initial non-lit screen. The refresh rate of this product is 60 hertz, which is less than what you might get on a larger projector, but for a mini projector, we were pleased with the results. The brightness is definitely the biggest difference between the mini projectors available. This mini projector has one of the brightest lamps available, boasting 110 ANSI lumens. Though it is quite high for the size, you will still need a moderately dim room in order to see the picture clearly and to provide the best contrast between light and dark.
A few of the other picture options with this mini projector include a variable image size of 10 to 100 inches. This is dependent on the distance the projector is from the screen. This mini projector also has an aspect ratio of 4:3. When viewing something in the high definition 16:9 format, the unit will just display the black bar on the top and the bottom of the image. If you discover there is a problem with the image being stretched or skewed, make sure the device the projector is hooked up to is also on a 4:3 aspect ratio setting.
