Rather than leave my screens as-is, and use the charts they come with, I cover the top edges of mine with paper clips.
These quickly accumulate notes (like my GMing goals for that session or campaign), PC-related lists (search totals, HP, etc.), counters I don’t want to lose track of — all sorts of things, in other words.
For me, that stuff is generally more useful than at least 50% of what comes printed on the screen. I leave the best 50% exposed, and get the best of both worlds. If you’ve never tried this, give it a whirl — you might like it!
