It would probably be helpful if you were a little more scientific about this.
1) put a thermometer someplace inside. Tell us what "hot" is (an actual temperature reading)
2) Get a sunshade and put it in the window, take temps again and see if the screen behaves better in the lower temps
3) Take a photo of the dim screen so we can see exactly what is happening
4) At what temperature does the screen "recover"?
While I suspect there is actually an issue that needs to be addressed by a repair shop, I'm also astounded at how few people use windshield sun-screens in modern cars to help protect all those LCD screens from direct sun and high heat.
Heck, I have two. One in the windshield, and the other blocking the drivers side window so I don't cook my backside on the leather seat when I get in the car at the end of the workday
