I'm thinking of buying an ultrawide monitor with a high resolution (i.e. 4k or 5k). I'm going to build a PC that will be capable of using that monitor. I also want to be able to use the monitor with my work laptop as a second or main screen and so will my wife. My work Macbook Pro has USB-C and my wife's laptop has DisplayPort so I know they will both be able to connect to the monitor as I will buy a monitor that has those connections. But if the graphics card of my wife's old HP Elitebook can't handle the native resolution of the monitor then what happens? will it simply not work at all and nothing will be displayed on the monitor? or will the display work but just at a lower resolution (the max the laptop's graphics card can handle)?
