1. When you see an LCD screen these days they are commonly LED lit, meaning that (basically) there is an array of LEDs behind the LCD screen emitting light outward (LCDs don't produce their own light, so they need some sort of "backlighting" or illumination)(It seems to me that CCFL edge-lit screens were popular for a good while, but everything that I have seen recently (last few years) has been LED backlit. Sorry, I don't keep up on screen tech too much.). You can probably still find TVs, monitors, and other LCD screens that are not using LEDs for the light source, but it is becoming less common these days, as far as I know.

2. Screen resolution makes a big difference for the general quality of the image that the device can produce. A super low res screen will make a hazy, fuzzy, and indistinct image which may cause eye strain. What you want is a good resolution to screen size ratio versus viewing distance. This number will vary based on the purpose of the display and the kind of electronic that it is housed in. E.g., a TV doesn't have to have as high ppi because the viewing distance is usually on the scale of 8-12 feet or so.

You can find general guidelines on the internet. I say, always get the highest resolution screen that you can reasonably afford.

The only thing I would add to your excellent answers is that for screen resolution even if it doesn't look fuzzy to you, it may still cause eye strain. I saw a huge reduction in eye strain when I bought my Nexus 7 2013. When I had the 2012 version it seemed fine to me but when I got the 2013 my eyes thanked me.

Yeah, a lot of the time you won't notice UNTIL you punch up to a higher resolution screen. Then you notice how crazy the difference is. If you adjust to the new display for awhile and then use the old one again you will often be shocked by the difference. Another thing that can make a huge difference is getting an IPS screen rather than a TN screen. Black levels, etc. There are many factors.

I was all set to put an anti-glare protector on my new Galaxy Note 10.1, but then read in the manual "Do not use a screen protector. This causes sensor malfunctions". I've never heard of such in all my years of using protectors on many, many devices. Any ideas of why this should be so?

BTW - the manual also says not to cover up the antenna (it will drain the battery!!) - which is behind where a cover would go. I assume they want you to use it naked all the time!
