(Of course) there are, especially in the 'processing' of the display, easy compromises. So it is much more susceptible to grease stains, but this can be remedied by a film and I have a feeling that I see a greenish screen with great sun exposure, but does not interfere.
With the price and instructions from known sources, the conversion for little money in a quarter of an hour is done!
