How to correct a blurry or unclear picture of your Optoma HD139x?
Question from customers
Could I have your help about my new Optoma HD139x? I just made my first installation and projection is imprecise, the entire image projected on the screen is not clear. How to take corrective blurred images?
Answer from justprojectorlamps.co.uk
For the image is blurry or unclear: Make sure that the lens cover from Optoma HD139x is removed. Next, check that the projector's focus has been set correctly. Make sure the projector Optoma is at least 1.4 m from the screen. With the projector off, check the projection lens to see if it needs cleaning. If necessary, use a soft, dry cloth to clean the lens. Do not use a damp cloth or cleaning fluid. Just a security rating: Never look directly into the lens when the lamp is on. If moisture has accumulated in the lens (as a result of moving between hot and cold rooms), leave the projector and wait about two hours until the condensation disappears. Also try changing the resolution of the computer. It is most convenient to match your computer or other input to the native resolution of your Optoma HD139x.
