I can see how just having a bigger screen would not really help that much. I imagine that it makes everything bigger when all you really need is for the target vessel to be larger, not the entire image. It's good that you posted though because I've often wondered whether a bigger screen would be helpful, or not. I would think that it would help a little bit because the image would be larger, but perhaps not more detailed. What is really needed is the ability to magnify the target vessel. I hope that someday the interface will have the ability to magnify just the target vessel, and nothing else. That is what is really needed. Thanks for posting!
