Ah, the hateful printed display protector film. The only *good* printing on a display protector is "peel here" or "peel before use" in one corner!
If your marketing people try to convince you a printed display protector film is a good idea, sack them!
I used to fix TV's and VCR's as a side business 40 years ago. For some strange reason many consumers left the protective film often with with the garbage marketing material on the flap or on the front panel of their VCR. I suspected the numbskulls thought it help its resale vale. But people leave protective film on all sorts of things - recently left on a touch screen on an audio mixer. Most people leave the energy efficiency label on their fridge. What for?! The first thing I do is remove them. I have a phobia of these things being left on. The adhesive dries and eventually its a pain in the arse to remove them.
I also noticed most people who paid big bucks for stereo HiFi VCRs, only played the audio through their TV set. In Austrlaia, they paid extra big money for VHS over Beta (when they were neck-and-neck in the market) because the uneducated consumer thought VHS was better quality because they cost more, and I think there was some saving face involved. The fact was, Beta was far more reliable due to a simpler transport mechanism, had a slightly better horizontal resolution, and had a smaller tape. VHS was crap. I owned Beta.
