Question about Epson Office Equipment & Supplies
Help says to press Fn + F4 button, what is the Fn button????
I suspect this is a message you're seeing on a notebook, computer or other device that has a keyboard. The "Fn" key is the "Function" key. When the "Fn" key pressed at the same time another key is pressed - in this case the F4 key, a different result will occur when compared to pressing the F4 alone. This works the same way as when you use the SHIFT key and a letter key - instead of a lower case letter, you get an upper case letter.
Typically, the keys on the keyboard are labeled in a light color. Keys that have a second purpose or function, will have a second label printed in a different color / slight smaller text or both. This label may be text or an icon or graphic. In order to invoke the second function of the F4 key, you will need to inspect the keyboard for the key that has is labeled with "Fn" text on it. Here's what a typical "Fn" key looks like:
The Fn key is in the lower left corner of this keyboard.
I hope this answered your quiestion and good luck!

Hi, Try lowering your laptop's resolution (Display Properties) to 1024x768 (or even lower like 800x600), before fn + F8. You can also try lowering the Monitor's screen refresh rate (60Hx). Another setting you can check is Advanced Settings tab or button and check settings for projector (instead of TV). If it works in the lower settings, you can try moving the settings higher until it quits again. If the above does not fix your problem, you may need to re-install your graphics/video driver. Hope this gives you an idea. Post back should you need additional information. Good luck and kind regards.

SOURCE: can't get projector to display
i have sold over 100 of these (useless)... projectors so i can tell you that you need to;
go to display properties in the laptop and make sure you can see 2 screens otherwise you wil get nothing out of the video output/vga depending which model you have. go to the projector menu and make sure auto is set for the source/input. if your laptop has VGA out set optoma to VGA. start the projector up again and then the laptop in that sequence. if you need any more help email me.

make sure you have the settings correct on the projector. select computer on the top panel. if still nothing, reset the settings to factory default (in the menu). also make sure you have matched resolution.

TURN OFF THE COMPUTER AND AS IT START6S MAKE SURE THE PROJECTOR IS SET TO COMPUTER SIGNAL AND AUTO SEARCH. USUALLY TURNING ON THE COMPUTER WILL CREATE THE SCREENS IMAGE AND YOU ARE DONE.

Reduce the screen resolution to 600x480 for instance and see if the projector can handle the low res output OK. Then increase screen resolution on the PC unitl the error message appears. Try the video menu settings in the acer
