So I purchased this (extremely yellowed) 1950-B monitor from eBay. I have an adapter to get its attached video cable to fit with an A1200. Problem is that the colors are rather whacky and cannot seem to be adjusted. The top of the screen is also a bit distorted. Any thoughts as to whether the problem is the monitor, the adapter, or something else? Anyone have experience with this model of Commodore multiscan monitor? Thanks, -Dave
