My 40" A550is up-and-running and I'm grinning at this point. I'm not sure if that's the $$ deal, the "1st HDTV" reaction, or if it looks that good, but I'll take it for now. I have run into some odds-and-ends between my inexperience, TWC/4250HDC, this thread's comments, and, of course, the TV itself.
1. I have an inexpensive HDMI cable connected and it is really good with one glaring exception for a while. I was really getting TERRIBLE reds in the picture. They were pure pink and no amount of adjustment would make any difference. The colors from the component inputs that I first connected were great, so I was trying to run both and compare when I discovered that the HDMI apparently "takes control" and there is no component out when it is connected. There is also no effect of the STB volume control when using HDMI. Both of those things consistent with the experience of others and this STB? Anyway, after unplugging and replugging the HDMI, the colors deepened and I reverted back to the default settings. I'm still not perfectly satisfied, though, as I think it has come back now and then. Anyone experience the PINK effect?
2. That might lead me into the picture mode issue. Personally, the Entertainment Modes haven't impressed me. The same lock-out of adjustments is true here as in the 650 series when Ent is engaged and they are bright, bright, and weak...IMO. For the evening, I'm in Movie, but was content with "Standard" this afternoon. Yes, I Reset the details after messing with the HDMI. I'm not above playing with the calibration later, but will have to find a good reason beyond brightness that the given modes handle pretty well.
3. Relative to an earlier posting: This is NOT the same remote that is shipping with the 6 Series; I believe this is the same as the 4 Series. It's ugly and awkward, but seems effective. I suppose everyone of us would have arranged the menus differently, but we will learn it all. While on the remote, what don't I understand about multiple remotes. Am I stuck with using the 4250 one to change channels on the box and only volume/mute/power on the TV while using the TV remote for all TV adjustments? It sure would be nice if the Samsung remote would change channels and control power on the STB.
4. I'm going to enjoy the TV, but the pink thing is worrisome. As I type, I am seeing a commecial that I watched earlier in good color and it is back to pink helmets on the Cardinals again. The NC State Wolfpack seem to have pink lanes on their court.....GRRRRR...
