Here is a collection of photos by a Discord user adrianb#5300 that shows off the difference between a modded Atari Lynx (with a BennVenn LCD mod kit), compared to the original screen. You can probably guess which one is which, but to clarify, the Lynx on top is the modded one, the Lynx on the bottom uses the original screen. What a huge difference in picture quality!
We have a comparison table of different LCD mod kits for Atari Lynx here.
As a side note - that original screen looks to be in mint condition, most Lynx consoles with the original screen look nowhere near as good.
