The HD27 and the HD143X are middle-cost models that have similar design, as well as a bunch of similar features. For example, they both have a built-in 10W mono speaker, 3D mode support, same projection method, resolution performance, etc. However, the Optoma HD27 vs Optoma HD143X comparison shows a significant difference in brightness, projection size, etc.
In general, both of the projectors are designed to be comfortably used at home and for business. However, the Optoma HD27 to my mind, is more suitable for movies, having 3200 lumens of brightness, while the Optoma HD143X has 3000 lumens. Despite the ability to achieve higher brightness, while receiving adequate color reproduction, the HD27 uses 195W lamp type, whereas the second model uses a more powerful 240W lamp.
The Optoma HD143X vs Optoma HD27 projection distances are 36 ft versus 29.5 ft, which is not very noticeable in practice, as both of the projectors aren’t short-throw. The contrast ratio also doesn’t show significant inequality between the models both in numbers and during the test: 25000:1 for the HD27, and 23000:1 for HD143X.
Despite the Optoma HD27 functionality, it works impressively quiet: the noise level is only 26 dBA, while the other Optoma’s model reaches up to 31 dBA.
Checking the Optoma HD27 vs HD143X in terms of their appearance, it’s worth noting that they both are square-shaped devices with rounded edges. So if you compare their overall appearance, these two look pretty much the same. Although, they go in different colors (the HD27 comes in white and the HD143X comes in black). The HDMI 1, HDMI 2 / MHL, and USB inputs are located on the rear panels of both projectors. The control buttons are classically situated on top of the units.
