Refresh rate and flickering

[apisorder]

I remember in the old times I had a 19 inch CRT when LCD monitors were just starting to emerge and were still expensive (well, the Sony 19 inch CRT was usd 600 plus tax if I remember correctly and that certainly wasn't cheap then, but with that money, you could only buy a 15 inch LCD I think ).

I remember I had the CRT monitor overclocked at 100Hz (or higher maybe) because at 60 Hz, or even 10 or 20 Hz higher, I would see flickering that probably no one else was seeing. Yeah, I have sensitive eyes.

But my question is, with the 21.5 inch HP Prodisplay v222va LCD I have been using, which only runs at 60Hz, my eyes are fine. What is the reason behind it? My understanding is that even LCDs can flicker, no?

Thanks.

LCDs and CRTs are completely different beasts. Your eyes are probably sensitive only to CRTs flavour of flickering. Or, many LCDs these days have anti flickering tech, as in they shut down the backlight between frames.
