I'm guessing, do you mean 'RGB' analogue?
If that's it, it means you can connect from an RGB video source such as a Sky or most Freeview TV set top boxes, or DVD recorders/players. Their output needs to be configured to RGB, usually via the set-up menu.
The sockets are indeed phono (RCA) connectors. The problem is converting from a SCART plug on the video source to phono plugs on the monitor; very few AV units have RGB OUT phono sockets.
Does anyone have an easy solution to that please?
If not, another option is to get a monitor with an S-Video socket (4-pin mini-DIN), as they're easy to connect to an S-Video source, using a readily-available SCART adaptor. In quality terms, S-video isn't far short of RGB. But not all video sources (e.g. Freeview boxes) can output video in S-Video format; only RGB or lower-quality 'composite video'.
There's a few more wrinkles to those options, but HTH for the mo. Please come back if you need more info.
