Agreed, the clarity of the newer monitors is definitely a cut above the older ones.
Mrs even asks to wind down the 4k resolution because it is too small for editing some of her scanned works. My monitor is still using a SVGA input for my day to day so am limited there before anything else. My USB dock only has 1 x SVGA and 1 x DVI which is plugged into another tower behind the desk. I run a few VM's on my laptop but they are all headless apart from one that I use to control the rest so hasn't been a problem.
Like riding unfashionable wheel sized bikes, you get used to it and don't realise what you are missing out on until you taste the secret sauce
