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.







Last note. The Optoma also did a good job on the opening black and white scene in Phantom, although several of the more expensive projectors are able to pull out some details in the left side of this very dark image.
