You don't say whether or not the "adapter" is simply a gender-changer, or if it actually converts the digital signal from the HDMI port to an analog one for the VGA port. Some monitors have both analog and digital input capability and can automatically adapt to the the digital signal, even if applied to the VGA (analog) port. Other devices are not so smart and need an actual digital-to-analog converter style adapter.
You should have a VGA port (3 rows of pins, blue connector on the laptop) plug in- or you could have a HDMI port. after connecting right click on your desktop and go to screen resolution. hit detected. the rest should be easy.
power ON your projector and laptop
connect your laptop and projector with VGA cable and press
if your laptop PANASONIC or NEC (Fn+F3) ACER, HP,SHARP,TOSHIBA (Fn+F5) LENOVO, SONY (Fn+F7)
DELL, EPSON (Fn+F8)
If problem exist remove the VGA driver in your laptop and reinstall the correct driver not a standard display driver
If your dell is equipped to do this it is on the back side and appears as a video card connector or s-Video out. It is possible that your Dell is not equipped to make this connection, I have found a few that are not.
The problem might be related to your native screen resolution. The C702TU laptop has a resolution of 1280 x 800. Most projectors do not support this resolution and if you cloned the main display, your projector cannot sync at this resolution. Look for an option to output a second display )instead of cloning) within your display settings. If your projector is plugged into your VGA port and turned on, Windows usually detects the second display automatically. Change the resolution on the second screen to something like 1024x768 or 800x600. These resolutions are supported almost universally across projectors.
