I cant get signal from my computer

That might be because of the weak or bad connection of computer or the projector. Also you should check whether the projector is out of order or not.

When I connect a computer to a projector no additional drivers are needed. Just connect the VGA or DVI port to the projector. The projector may be the limiting factor, though, as far as detecting the signal from the VGA cable, and you may have to follow the instructions of the projector to make it work correctly as far as when to power up the computer and what not.

Good luck on this.

Video card may be going out or is malfunctioning.

i connecto laptop my projecto useing display cable but not display

It has nothing to do with installing English version over Japanese version , check it whether it shows in device manager or not,installed it. If you don't get the message"New Hardware Detected" when you plug the projector into the laptop, you probably don't have the drivers for the projector loaded into the laptop or computer and the computer doesn't recognize the projector. After your finished using the projector, be sure to disconnect it properly from the laptop. There is an icon in the tray, "Safely Remove Hardware". De-activate the projector BEFORE you pull out the USB cable from the laptop.

Reboot your Laptop, while connected to the projector which has been turned on in advance. Otherwise, simultaneously press Fn + F5 for the command to to transfer to other monitor plugged in. Toggle and wait at least 1 minute everytime to allow the computer to stabilize

if you get no power, you'll need to replace the power supply. if you are just not getting a signal, reset the settings to factory default on the projector and replace the cable.

Hi and welcome to FixYa,

Initially, the "No Signal" error message indicates just that, it is not receiving anything or that the signal it receives is beyond its capacity. With this in mind, pls check:

• the cable connection from PC to Projector;
• that the PC is set to display on a 2nd monitor, TV or Projector depending on the capability of the PC's video card (Twin View or Dual View); or
• as main monitor;
• lower down the computer's Screen Resolution and/or Screen refresh rate.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

i hope that is a USB driver issue when u plug your device does your computer detect any usb device and then its says unknown/unrecoginzed device. You have to check the cables first then you download USB2.0 driver install it inyour computer andl aslo try to connect the device in another port also put the the driver cd for the TV/projector

Click the 2 box on the display settings and put a check mark ano the box that is say to extend the view on to this monitor. Hope this Helps.
