Connect aspire v5-552p to tv


It depends on the ports the computer and the TV have
If both have VGA (blue) use a VGA to VGA cable.
You can also use an S-Video-to-S-Video cable
If both have DVI, use a DVI-toDVI cable.
If both have HDMI use an HDMI-to-HDMI cable.

Other possibilities are combinations of the various modes above VGA-to-DVI, VGA-to-HDMI, VGA-to-S-Video, etc.
VGA-To-D

I have an HP m9000z that was previously used with a DVI cable/monitor. I only have a VGA cable/monitor and the pc doesn't access the monitor.


This PC has a VGA and a DVI ports? Are both ports on the motherboard or a Video card? Or is the VGA onboard video and DVI is a Video card? You may have to disable the DVI port to get Video to vga or enable the vga port.

Hi there, I'd like to connect the Acer S202HLBD 20"" LED Monitor with a Mac Mini which cabling would I need?


It all depends on what kind of PORT connection you have on your MAC either VGA or DVI. If your Mac has VGA port then you need to use the blue cable that comes with your Monitor when you bought if you have DVI then you need to connect the white cable.

How to know if you have VGA or DVI or BOTH.

1. Check the sides of you mac and see if you have a blue port. Blue port means you have VGA port
2. IF you have white then that means you have DVI
3. IF you have both then you just need to use 1 connection. I prefer DVI since its digital.


Your feedback is greatly appreciated. Thank you for using FIXYA.

I want to connect a HP w2207 monitor to a HP TouchSmart IQ770 PC. What is the best way to do this?


Your HP w2207 monitor has support for both VGA and DVI inputs. This therefore means that you can connect your HP TouchSmart IQ770 PC via either of these two connectors.

VGA is the blue coloured port on the rear of your monitor.
DVI is the white coloured rectangular port located on the rear of your monitor.

DVI is the better connection of the two as it is a digital connection, so use this one if you can, alternatively you can use the blue coloured VGA cable to connect your monitor to your computer.

It all depends on which output, either DVI or VGA is found on your Computer. Remember VGA is the Blue coloured port and DVI is the blue coloured port.

All the best!

How can I hook up MacBook Pro with Optoma 1690 Projector? Am I supposed to hit a certain function key to get Projector to see MacBook


You may need a certain connection (MiniDisplay Port to DVI, or MiniDisplay Port to VGA). If you're connecting to an HDMI-compatible projector, you'll need an adapter. You'll also need an adapter if connecting your MDP (MiniDisplay Port) to a DVI or VGA port. Here are some helpful links:
#1 MDP Adapter Video (YouTube)
#2 MDP to HDMI Adapter (RadioShack)
#3 MDP to VGA Adapter (Apple Store)
#4 MDP to DVI Adapter (Apple Store)
