Here's a question I've thought about from time to time:

What is the upper limit for resolution and image quality on a typical 15khz monitor?

We all know 640x480 is not Standard Definition. That is a range of resolutions, but one of the higher ones is 720x576i@60hz with 16 lines of horizontal blanking.

However, it maybe possible to exceed this with a PC. What will happen when the signal is sent to the monitor? I believe this is related to the pixel clock isn't it? Could one get away with higher frequencies? 800x576? Can one "overclock" a good CRT?

As an aside, I download "SD" rips of old television shows sometimes and they're almost always in 640x480. It's a loss of 8% in resolution right off :/
