Optoma HD70 Projector Review - Image Quality-4

8 Bit Color per channel (24 bit): One minor downside to the HD70 is that it processes colors at a maximum of 16 million colors. Now that may seem like a lot, but almost all home theater projectors today are at least 10 bit, which gives you about 1 Billion colors. Believe it or not, you can see the difference. If you have 8 bit processing, you may run out of subtle shades in a face, so you get a bit of flatness, in the image. In the case of the HD70, this is true, but barely visible. I was able to spot this on occasion, but rarely unless I was looking for it. This limitation may occasionally bother those extremely critical, but for most people its just fine and a minor tradeoff against a low price and good performance elsewhere.
