I think what you are seeking is.....


http://www.tvcalculator.com/

you can see two sizes of monitors or TVs side by side.

Make sure you set the aspect ratios correctly. TVs are 16:9, while PC monitors are 16:10

Not entirely true. Most of the time yes, but I do own a 16:10 TV and 16:9 Monitor.
Just check the specs and then put them in.
