Is there any way I could check on the physical size of a screen when I put a cd or memory chip in and adjust things at that time.
That statement really doesn't make sense. You mentioned HTML, so you're creating web pages, right? Although you have a 22" monitor, most computer users have a smaller monitor. And, obviously, you should take that fact into account when designing your web pages. For example, as a base standard for your web pages, you might create you pages to display on a 17 inch monitor set at 1024 x 768 resolution without horizontal scrolling. In other words, make your pages a fixed width of not more than 1024 pixels. And, many web designers use a smaller width, perhaps 800 pixels, which would display on a resolution of 800 x 600 without horizontal scrolling.
If you don't know how to create fixed width page when coding HTML, then you still have some more learning to do.
