Question about Optoma H56 Multimedia Projector

"Sunshine" Glare on faces and other bright areas

I've tried all the picture and image adjustments, but lately the glare has been very obvious (don't remember noticing it on the first few thousand hours of use). I've changed bulbs, but the same problem. Tried a few different DVD players, same problem. Don't notice it with the other LCD and TV displays. Thoughts ?

How do I adjust contrast?


There are Function Keys to do this.

from Troubleshooting section. Keyboard (if contrast and brightness function key)

and Page 10 of the manual
Display Keep your display clean. • Keep your head at a higher level than the top edge of the display so your • eyes point downward when looking at the middle of the display. Adjust the display brightness and/or contrast to a comfortable level for • enhanced text readability and graphics clarity. Eliminate glare and reflections by: • placing your display in such a way that the side faces the window or • any light source minimizing room light by using drapes, shades or blinds • using a task light • changing the display's viewing angle • using a glare-reduction filter • using a display visor, such as a piece of cardboard extended from the • display's top front edge Avoid adjusting your display to an awkward viewing angle. • Avoid looking at bright light sources, such as open windows, for extended • periods of time.

SP 4805 LOUD BUZZING


i would suggest that you get another one. if this is the second time you are having to replace the same part than there has to be a reason that it is breaking over and over. projectors are funny when it comes to parts and service. even thought something looks like there is something major wronge it could be just a dirty lens from the inside. and than when it is simple it is usually something major that needs repaired. It is only my opinion that you buy a new one. but i will direct you to where you need to go to get the parts you need to fix the problem. i will post another comment in a few.

Glare from laptop


LOL, not much you can do about the glare unless you buy some type of cover that goes over the screen.

Have you tried darkening the screen by using your keyboard keys that controls the brightness and darkness? Usually they work in conjunction with the FN function key.

I have a CQ56 compaq and do not know which type of screen to order a matte or a glossy screen.


The Two Kinds of LCD Monitors lens1946174_1208282041macbook-matte-screen1.jpg There are two kinds of modern LCD screens: matte (anti-glare) and glossy. Both have their pros and cons and are a subject of many discussions.

Matte screens don't get glare or reflections on them; however, the same rough surface (polarizer) that reduces the intensity of reflected light results in less contrast and brightness since the light from the LCD screen passes through it. Matte screens diffuse light instead of reflecting it so they might be easier to read outdoors, if the backlight provides enough brightness. You don't have to worry as much about reflections as with a glossy screen.

Glossy screens have vibrant colors and the highest contrast and brightness because they have a smooth, high-gloss surface. As a result, it is often the choice for movies or gaming. However, strong lighting causes glare on these screens which is very annoying and may tire your eyes if you have to stare at it all the time. You can also see reflections on the screen. Some graphics designers may also find the colors inaccurate. Glossy will work great for you if the lighting in your room doesn't create any glare on the screen.

Touchscreen has problems with glare; can't see image I want to photograph; also touchscreen surface is mottled;


touch screen has problems with glare look through your options and see if there is a setting to turn up the brightness or a daylight setting. I have 3 tablet pcs a half dozen palm and pocket pc devices, none of which can be veiwed worth a $#!t in direct sunlight. Your best bet is to plan on whereing a baseball hat and holding your camera close to your face if you want to see it in sunlight.
I am not sure if i understand what you mean about the mottled part.

Glare on lcd screen


it's pretty normal.. try wearing a brimmed hat to create shade, turning the brightness up on the screen, the lcd's tend to get washed out in the bright sun.
