The term "monitor" is a misnomer. It refers to any TV with an external video input.
No need to curse Denon. This isn't a simple stereo receiver. It's a well functioned home theater receiver and as such was designed to be used in conjunction with a TV. It has a lot of different settings and a lot of those "hidden" functions you read about in your manual are only accessable via menus that can run several levels deep.
You should be able to use your existing TV if it has a video input. Just find a common video connection from the receiver's output to the TV's video input.
At worst, you can pick up a cheapo RF modulator for 30 bucks or so to converrt the composite output (yellow jack) of the Denon to an RF signal. It isn't the greatest picture but it will "work" for now.
Of course, this presumes your receiver will output all the need info through the composite video output. RTFM for more than this.
not knowing your TV I'm somewhat at a loss, but...
...my Denon 2802 is connected to my Proscan tv (not a monitor) via an "S-Video" cable.
Does your TV have this?
Again, check your manual to see if the TV can be connected to the Denon by a composite (yellow jack) cable.
HALLELUIA! I got it working!
Thanks to you guys, I finally got my SVS sub working. I took your advice Mark and found the RIGHT plug for the monitor. I got the set up screen and the Denon manual finally made sense. I also had the sub plugged into the WRONG plug, over by the video plugs, and put it in the right plug and, between that and setting up the speaker configuation and setting the perameters for the sub and bookcase SVS's, it worked! Thanks for your patience and advice.
