Sharpness and Resolution

Both of these projectors have a native 1080p resolution. The Optoma HD243x pairs this with an upgraded DLP processing chip, and as a result, the image has a sharper overall look, with less movement blur and no pixel fuzz.

There are two sides to this equation for a projector: the build quality of the casing, and the longevity of the lamp. On the first point, both the HD143x and the HD243x feel sturdy enough for basic home use. They are plastic, so you’ll need to be careful when carrying them from place to place. As long as they’re not dropped or otherwise damaged, however, Optoma projectors can serve you well for years.

When it comes to the lamp, the HD243x uses an upgraded lamp that will give you a longer, stronger performance. In both cases, you can measure the typical lamp lifespan in the thousands. With the Optoma HD243x, however, you get up to 15,000 hours. That’s over 10 years if you use your projector 4 hours a day.
