Thanks for making this post. I would generally agree that contrast ratios are to be ignored. On the other hand, I think it's important to acknowledge that some technologies are inherently better than others for contrast.
Here's how I would line them up:
- OLED - Once organic light emitting diode displays hit the market, I think we will start revisiting contrast ratios. This will be the ultimate contrast display - nearly infinite due to the OLED light emission.
- Plasma - As each colored pixel emits its own light, these displays can give fantastic contrast.
- LED with Full Array Dimming - If you buy a display with an LED array and strong micro-dimming, you can achieve very strong contrast.
- LED with Edge Dimming - These displays are similar to Full Array dimming but are controlled from the sides and are therefore not as powerful.
- LCD with CCFL Lighting or Standard LED - These have very weak abilities to generate strong contrast.
If you're interested in this subject, I put together a guide that includes a lot more info on contrast ratios and other issues that affect picture quality.
