Quick, you’re shopping for a Blu-ray DVD player at your local electronics store and the sales associate starts speaking terms like “progressive scan, profile 2, and up conversion”. You know they’re speaking English but have no clue what they are talking about. What do you do?
With technology changing so fast and new consumer electronics products seeming to hit stores daily it’s very confusing and hard to keep up. Adding to the consumer confusion are the product brands who use their own unique terms (some call this “marketing-speak”) to try and differentiate their products from competitors.
We’re putting the consumer back into consumer electronics by describing those terms in a simple language anyone can understand. Presenting “Geek Speak” for HDTVs, DVD Players and Home Theaters. Bring it with you on your next shopping trip and shop like a pro for your home entertainment needs!
- Plasma or LCD: Both great. If buying 50-inch and up, go Plasma for anything below 47-inches, go LCD.
- Screen Size: 1.5 to 2 times the diagonal size for optimal viewing distance; 42-inch TV equals 6 to 7 feet
- Refresh Rate: How fast your TV displays images. 60 Hz is standard, 120 Hz equals less blurring.
- Inputs and Outputs: Inputs determine video quality. The picture is only as good as the signal.
- 1080i vs 1080p: i (interlaced) scans half the lines at a time and p (progressive) scans all lines at once for a smoother picture
