Has Apple corrected this on iMac M4 machines yet? I was going to buy one to replace my 2015 intel iMac. My 27 inch Retina screen is terrific. Watching Netflix etc on it is better than TV. Rumor that a new iMac design is coming out? Hope it is as good as my intel iMac...

Do not buy an iMac from the current models.. M1 displays are failing, but most likely m2 m3 m4 will start failing in the future if they don't fix the display design. Get an iMac mini, but stay away from the current iMac displays.

I also recommend looking at a Mac mini and one or two decent aftermarket external displays.

The problem seemed to be limited to the M1 iMacs only.
If you're considering a new 24" M4 iMac consider the following: a 10 Core Mac Mini M4 with 16 GB RAM and 1 TB SSD ($999 + tax) with a 27" LG 4k monitor ($250 + tax from Amazon.com) is $1249 + tax which is $560 less than a similarly configured new 24" iMac ($1799 + tax) re 07/2025.
You can save even more if you get a smaller monitor, i.e. 27" w/o speakers.
I got the combination above and it's a terrific setup - blazingly fast. I am extremely happy with my choice.
I got the 32" monitor because I wanted to run it a reduced resolution (due to failing eyesight) and still have adequate screen real estate.
Just some food for thought.
