I didn't even know LCD's were affected by sunlight/uv light. But I don't live in a particulairy sunny climate.
But it would be interesting to see if different brands/models react differently.
Just like the cold temperature test where some LCD's just became unresponsive where others just seemed to keep working fine, like in that keysigth U1282a where the display wasn't able to update anymore. Not that I would experience those type of temperatures here, but interesting to see nonetheless
