|"Please do not post email address..."|
If you can see an icon at the top of your first post at the far right that looks like a notepad, you can click on that and edit your own post - you should remove the email address.
You should see that notepad icon for any other posts other than the first one in a topic you start , but maybe not the first one after at least one post has been made.
Some computer monitors will display a message when they are NOT receiving any video signal. One of those possible messages is "Out of Range".
Your particular monitor will probably produce the same message when it's video cable isn't connected to anything.
READ the installation and cable connection directions for the external TV tuner.
If your external TV tuner is capable of NTSC TV , or PAL or SECAM TV, or digital TV, that must be set right for the type of TV signal you are receiving at your location.
Some TV tuners are capable of receiving "over the air" digital TV, but you must have "over the air" digital TV avaialable in your area in order to get a signal, and you must connect a digital capable antenna for that purpose to the TV tuner. E.g. That's not available where I am - I must connect to a coax cable that has a digital signal.
If you can connect to the monitor from it via a VGA or DVI cable, use that type of connection for the best display on the monitor.
READ the manual for the computer monitor.
You haven't stated which model it is. Some computer monitors can have two or more video sources connected to them. If your model is one of those, the default video source may not be the one the TV tuner is connected to, and in that case, you get no video and the "Out of Range" message. In that case, you need to change the video source setting for the monitor, via pressing on a button to toggle which video source it's using.
