I'm looking at replacing my Sony RPTV with a 2012 Panasonic plasma this year. My TV is set against an eastern wall in a room with a high ceiling. The only sunlight comes from two windows up high about halfway back along the northern wall, but it can be quite bright, especially in the summer, as the sun moves north.
I watch TV mostly in the evening during weekdays and sports during the day on weekends. I don't care that much about applications or 3D, but that might change in the future.
I have been looking especially at the GT50, based primarily on its THX Bright Room and THX Cinema modes. I know those modes are not the same as proper calibration, but i like to keep things simple. I've read that they deliver very good pictures in the two environments that I watch in, and I envisioned just switching between the two. I can't tell if there is anything comparable on the ST50 that would allow me to do the same thing.
One concern that I have with both those models is the louvred panel. My TV sits about 5 feet high, and I sometimes stand or walk around as I watch TV. At six feet tall, would I notice a reduction in brightness as I did so? Also, would those filters affect the sunlight coming from the windows about 15 feet above and to the left of the screen? If not, would I be better off getting a UT50 (which doesn't have the louvred screen) and just block the sunlight coming from the windows?
