Lots of folks recomending the mobile version, but I understand you want to see it bigger on your monitor. I'm not on the comics team, so consider this work-around advice from another player, rather than anything official - because it's a super crappy bodge! It's for Chrome.
- Set the comic viewing options to full-screen, and scrolling (rather than clicking).
- In Chrome, right click the page and select "Inspect" or press Ctrl+Shift+I. (i)
- Ensure your tool display is docked to the left hand side (click the three little dots in the top-right of the tools panel, and select the second icon in the "Dock side" menu).
- Toggle the device toolbar (the little phone/tablet icon in the top left of the toolbar, or Ctrl+Shift+M).
- In the device toolbar that appears at the top of the screen, select something like "Ipad Pro" - don't let it pick "Responsive" for you.
- In the zoom-level drop down (to the right of the 1024x1366 resolution display) select something to make the page bigger - 150% or 125% work for me.
- If your tools panel is taking up too much of the screen, you can grab the handle on the edge of it, and resize it a bit.
And you're done. The pages should be significantly bigger on your big monitor now, despite losing about 20% of the screen to non-comic nonsense from Chrome. When you want to go back to normal reading, just click the X button for the Inspector window, or press Ctrl+Shift+I (that's "i" not "L"). If you want to see the whole page at once, then you can just press Ctrl+Shift+I to toggle back and forth, but it's pretty awkward.
Good luck!
