Mitsubishi LT-46148 LCD HDTV - Review (1/3)



By Richard Fisher

Summary: Better than expected for casual viewing applications

LCD has come a long way since just a few years ago, taking over the flat panel market up to about 50" in screen size. While Mitsubishi is far better known for rear projection DLP since the demise of CRT, market forces can't be ignored and consumers remain spellbound by the flat panel concept in their homes. Let's see what Mitsubishi has to offer and how their LCD products compare.

Since last year Mitsubishi has offered 40", 46" and 52" models and the LT46148 is part of their current line of 1920x1080 displays.
