@sam-pinansky I can't say for sure because I don't normally use Edge for anything, but it appears to be in some sort of "make it fit" mode which doesn't allow the pages to open vertically to their full size. I'm not on a 4k, but my monitor is 36 inches. When I tried to open it, I think the combination of the "make it fit" and screen size make it blur beyond use.
I actually did make the assumption based upon the graphics pages at the start of the novel, so the scaling issue would make sense. Honestly, looked at that and decided I should try to find an answer to the problem.
Will be getting calibre to use as a reader. Also did not realize that epub was a container file, so 7-zip will also come in handy for viewing those first few pages.
Everyone, thanks for the advice in resolving this.
