You only need to do a monitor switch if you see the rig you want to display. But if you are a worried person and do not have much time maybe buying a lot of monitors is the best option. If you have 5 rigs then you should have 5 monitors. Price monitors are not expensive and this is very beneficial for our mining business. Oh yes you can also do it easily, you can install remote application and you can access your rig from anywhere so the need to have many monitors can be avoided. Back again that it all depends on you because you are going to play an important role in building and running your mining.
