Help! I recently purchased a new monitor supposing that it would be
compatible with my Amiga 500. From the specs, I thought it would work,
but when I connected it up, all that I get is a black screen. Whay I
am going to do is post the monitors specs, and beg upon the great wisdom
of you guru's to tell me if it is indeed compatible, If I've hooked it
up wrong, or maybre I've gotten a broken monitor.
The monitor model number is the RELISYS 5155. Here are the specifications:

Well, Thats all I can gleen from the owners manual. It looks like a good
monitor. Swival Base and all. It only cost me $430 plus COD. Did I get
stuck?
Your help will be appreciated.

It looks as if you may not be buffering the HSYNC and VSYNC lines.
The Amiga expects these signals to be driven if there's a genlock attached.
If there's a genlock attached, then Amiga expects an external clock, and
switches over to that clock. Since you don't have the clock there, the machine
doesn't run. Buffer those two with something like a 74HC08 and you'll be
all set!
