Blood for the Baron!

If you're new to CDisplay, I advise opening up a file, right-clicking, going to Configure and ticking the "Fit Width" box.

This gives you full-screen view.

You can navigate solely with the wheel mouse, or scroll using the keyboard arrows and the Page Up and Page Down keys. Hit Esc or X to exit.

This version of Cdisplay is the unofficial upgrade, as the original file creator has disappeared. Both sites are now offline.

Is that Fit Width or Fit Width If Oversize?

Fit Width. The other one will shrink the double-page spreads to unreadable proportions.

Ah cool, that's what mine was as default, thanks for that.
