Hello i have an old mac mini 80 gb but i am not certain when i bought it,probably about 10 years ago,i have bought a new mac mini for the wife and wanted to use the old one for me,i am using a television as a monitor so i bought a mini DP to HDMI to connect the box,the television source is set as HDMI but when i turn the mac on all i see on the television is HDMI no signal,can anyone please.
Here are some troubleshooting steps that I would try: Reset the SystemReset your Mac's and Try another CableAlthough you are using the official MiniDVI to VGA adapter, it is possible that it might be damaged, so I would try connecting your monitor with another official adapter. Reset the Resolution.
Start up in Safe Mode ( Power + Shift on startup). Apple Menu = System Preferences. Choose Displays from the Views menu.
Select another resolution and refresh rate. Restart.Software UpdateIt is also possible that you need to update to Lion (Maybe even Mountain Lion if you want). Other Links and ResourcesAnother Apple user who was using a Powerbook with the Acer x163W had issues too. That question was answered and recommends a different monitor because of the Acer monitor's lower resolution than his Mac. One thing to try-I was getting the 'No signal' message on my external monitor, and couldn't work out why it wouldn't connect, as I was using the correct cable and it has worked many times before.After trying many things, I unplugged the cable from my laptop, turned it upside down, and plugged it in again. So, unlike a USB, this cable fits both ways, but only works if it's the correct way up.
When it's the right way up, it has a little image of a rectangle on it. (This may differ depending on your cable.)I know, super obvious, but I was puzzled for a bit.
