VGA-HDMI connection fail on Acer projector using adapter


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.

Connecting sanyo pro xtrax multiverse projector to a Macbook pro


VGA to HDMI cables don't work. They're a con. VGA is an analogue signal. HDMI is digital. It's not possible to convert from one to the other with just a bit of wire.

I am trying to hook my notevision projector to my laptop so that i can show a powerpoint. I did not receive a cord with my projector. Which cords will i need? I received a usb to usb and VGA cord but i...


I tend to use the VGA cable. Once connected, switch the laptop on until you get to the desktop, then switch on the projector. Some will see the signal, if not, simoultaneously press your FN and relevant 'F' key to send the signal out to the VGA. You may need to do this 3 times, once to send to projector, one to send back to laptop screen and then once to send the signal to both projector and laptop screen. Sometimes this can take a short amount of time. You may want to change the projector settings to the VGA input so it doesn't constantly search for a source. If you still have problems, go into properties on your laptop and advanced. you m,ay need to unclick the box saying 'Extend to..........' (You should find what I mean from this, I am in front of a pc therefore the settings are slightly different.)

If nothing then works, it may be your video card.

Good luck

I am connecting the VGA cable but still no signal can u pl help


There are two things to try. One is on your laptop. Hit function 4 on your keyboard. You should pop into a screen that allows you to send signal out from your laptop to the projector. The other is to go into the menu on the projector and adjust it for either the port you are on or set it up for "auto-detect" When the menu comes up it should have a video section and then an input select. Your VGA inputs on the projector should be labeled something like VGA 1, VGA 2 or something like that identifying the ports. Then in the menu select that port. If these two things do not work give me another posting and we can get this fixed.

Need to get a torpedo projector to work with laptop


Unfortunately, there is no simple VGA-to-RCA adapter cable if you're connecting to a composite video input (usually colored yellow) or s-video input. VGA output is separate red, green and blue video and synchronizing signals, and they all need to be combined. You need a VGA-to-video converter to do this.

If the projector has component video input jacks, then you can buy a simple adapter cable.

Hope this helps. Thanks for using Fixya!

Projector will not detect a Dell computer


Computers do not generally send an RGB signal, you should be connected via a VGA cable between the projector and the computer. The input menu on the projector should be set to VGA. The output of the computer should be equal or lower to the maximum resolution of the projector.

Dell 3100MP Projector - No Signal Check Cable


Make sure you have the right input source selected. It may be looking for a signal from some input other than the one you're connected to. Beyond that, if it truly isn't seeing the input then you'll need to have the projector serviced.

Connecting Macbook with a compaq MP1400 digital projector


You're going to need a conversion dongle that goes from the Mini-DVI to VGA.

Then:
  1. Connect one end of the projector signal cable to the Video Graphics Array (VGA) connector on the projector.
  2. Connect the other end of the projector signal cable to the Digital Video Interface (DVI) connector or VGA connector on the notebook computer and tighten the screws.
  3. Connect the projector power cord to the power cord connector on the projector.
  4. Connect the other end of the power cord to an electrical outlet that is easily accessible and close to the projector.
  5. Turn on the projector first, then turn on the computer.
