It should work fine. As long as you have the right connection in the back of the 1200. I use mine all the time if my 4000 starts acting funny so i can see the colored screen since they wont show up with a picasso card. They are great video monitor. I use mine hooked up to my VCR and my DVD player. Once it is hooked up you do have only a certain amount of resolution you can use. :-D :-D
