The monitor I use for work is 43” and can double as a TV. It also has 4 HDMI inputs, which can act as 4 displays. I could, in theory, watch TV via a streaming box, play a console, and still have the equivalent of 2 21” monitors going at the same time. I’d love this kind of flexibility on my primary TV in the living room.
Is this something you're actually able to do with this monitor, or that you think it should be able to do it? If it can actually display all 4 inputs at the same time, I'd be interested in knowing the model and price of that monitor. That's a feature that tends to require special equipment that's not cheap.
