SOURCE: toshiba laptop won't work with new optoma projector

-toggle the laptop display using the FN keys and F5 I believe. -lower laptop resolution to 800 x 600 -look in laptop display properties for lcd or external display settings, see if it (external crt) has to be enabled on the laptop first.

Hi, Perhaps you can try lowering the screen resolution first of the laptop before plugging in the projector and then the Fn + F8. Thereafter, gradually increase the screen resolution until projector stops displaying. The idea is that your current screen resolution maybe too much for the projector to handle. This of course is assuming that there is no hardware problem with the projector. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

SOURCE: Connecting a Optoma Projector to a Toshiba Laptop

I bought mine new... hooked it up and got the same response. I would have torn my hair out but I am bald! Checked everything. Great frustration. Finally, I thought to replace the cable with one I have on my monitor. Worked perfectly! A brand new cable and it was faulty! Contacted the company and they sent out a new one. Even sent a packet to ship my bad one back so they could find out what happened. No connection problems with the new cable.

Most projectors have air filters. Yours may need to be removed and cleaned. No air flow = overheat.

We just solved a similar issue. Most likely your PC or laptop is currently set to a display resolution that is too high for the projector or is one that it cannot handle. Try setting your computer display to 640 x 480 or 800 x 600 and see if you can get the projector to work. If it does, then you can figure out the maximum display resolution you can use. Also consult your projector documentation for supported resolution modes.

For the PICO in particular, it looks like those are in general for small mobile devices (320 x 240 or less displays), and the PK102 model has native VGA (640 x 480) support with extended support for 800 x 600. You will not be able to use this on most modern computers except at the lowest resolution setting for the PC.
