Question about InFocus ScreenPlay 4805 Multimedia Projector

1 Answer

My projector can't handle white

Whenever any white image is displayed on the screen the projector immediately auto-adjusts the image, losing a few seconds of whatever I'm watching. Anything like on-screen explosions, gunshots white skys etc set it off, not to mention browsing the computer becomes impossible. Any suggestions on how to fix or have I just wasted $3000? Cheers

Hi there

The next time you send your Projector for a service ask the technician to check the run rates on your colours as well.

It can unfortunatelly only be done properly in the Service Menu of the unit.

Keystone not working


Manual: http://www.mitsubishi-presentations.com/wp-content/files_mf/mitsubishi_manual_xd250ust.pdf

Installation>Wall Screen>Keystone

The automatic keystone adjustment may not be carried out correctly

because of the ambient temperature and the installation

conditions of the projector and the screen. In such cases, correct

the keystone manually.

• When the projector is projecting images where acceleration is

present, such as in a vehicle and aircraft, the automatic keystone

adjustment may not function correctly. In such a case, set AUTO

KEYSTONE in the INSTALLATION menu to OFF and correct the

keystone manually.

• You can correct the vertical keystones. However, their adjustment
ranges are limited in such correction.

When the keystone adjustment is carried out, the adjustment

value is indicated. Note that this value doesn't mean a projection

angle.

• The allowable range of the adjustment value in the keystone

adjustment varies depending on the installation conditions.

• When the keystone adjustment takes effect, the resolution

decreases. In addition, stripes may appear or straight lines may

bend in images with complicated patterns. They are not due to

product malfunctions.

• Noise may appear on the screen during the keystone adjustment

because of the type of the video signal being projected and the

setting values of the keystone adjustment. In such cases, set the

keystone adjustment values in the range where the image is displayed

without noise.

• When the keystone adjustment is carried out, the image may not
be displayed correctly because of the type of input signal.

LCD projector not displaying image of the laptop


On that Dell, you have to tell the laptop to display the image on an external unit--look on either F4 or F8--you will find a small TV screen symbol. You have to press and hold "alt" and press the key. The options are, 1-show image on just the laptop, 2-show the image on the laptop *and* something else, (like a projector), or 3-show an image on JUST an external display. NOTE: Sometimes, you have to turn on the projector FIRST, then immediately turn on the laptop so they boot together--just one of those strange things...(remember, **for example** first press of "alt" F4 will get you laptop and projector, second press of "alt F4 will get you JUST the projector, third press of the keys will bring you back to just the laptop)---Rick

PT-L735 U projectors. Green screen and stretched


The green is the result of the blue device failing. Happens about 4000 hours or so. LCDs can't handle the heat. Check the scaling of the image of the second projector. 16x9 vs 4x3.

good luck

Colors showing red on screen


Hi Stella,
There is a button on the projector called "Auto Image"
Most people don't realize it's even there.
Press it while you are seeing this problem and most likely the projector will figure out the image issue and all will be well.
Note: this feature is nowhere in the menu(s)

Good Luck!

Screen adjustment


Adjust the screen area of the computer’s display settings to match the projector’s native resolution. Refer to your projector documentation for the optimum or native-resolution setting for your projector model. If you can't find this information or are uncertain, most projectors support a maximum of 800 x 600 pixels.
• With certain laptops, you might need to disable the laptop display to obtain the best image, especially when the native resolution of the laptop exceeds the native resolution of the projector.
• Font smoothing will automatically generate a cleaner font outline, both on your laptop and on the projector. To apply font smoothing, do the following:
1.
In Control Panel, open Display.
2.
On the Appearance tab, click the Effects button.
3.
In the Effects dialog box, select the Use the following method to smooth edges of screen fonts check box, and then select Standard or ClearType in the list.


If the projected image is dimmer than it was on the laptop, check your projector documentation for information regarding lamp timers. If the lamp life has expired, replace the lamp for maximum brightness.
If the projected image is not rectangular, try one or both of the following:
• Make sure that the projector is perpendicular to the viewing screen.
• Raise or lower the projector.
If the projected image displays vertical lines, "bleeding," or spots, try one or more of the following:
• Adjust the brightness of the image.
• Check the projector lens to see whether it needs cleaning.
• Adjust the sync and tracking on the projector.
