Watching nothing but CNN for 24/7 doesn’t seem like a particularly realistic test. Also basing conclusions on a sample of 1 is also rather misleading.
Since we are doing anecdotal “evidence”, here is mine tonally scientific test: I bought my Alienware aw3423dw at release and have been using it as my work and gaming monitor since than. I use dark mode and don’t watch CNN on my monitor, but it has over 6000 hours of use so far and no burn in…
I did not expect the Steam Deck to perform so well at 15w. Very impressive.
