Thanks all, please keep the stats coming. We are collecting some good info. When we have enough, I'll tabulate the data and post so we can see them all side by side. There is the same thread over at avsforum and I will combine the results. HTF: 5 posts (with actual numbers). AVS: 3 posts :)...

Still though, the amount of information presented to the eye: in 1/60th of a second: 1080i gives 540 lines (rows) x 1920 columns = 1,036,800 pixels = 62 million pixels/second (of displayed info) 720p gives 720 lines (rows) x 1280 columns = 921,600 pixels = 55 million pixels/second in...

Brad, On the sub hum thing, does it still hum when the audio signal is disconnected? If so, I'd say its the sub, and there's not much you will be able to do other than try moving it to a different location and see if it still hums. Try grounding the metal chassis of the sub amp with a thick...

Any of you X1, PT300U owners want to jump in? thanks A

Hi everyone, I would like to get a feel for optimum viewing distances with various LCD/DLP front projectors. Optimum would mean a smooth picture without pixelization/screen door/visible video lines. I'd like to suggest the following poll. Please share the following with the forum, (if you...

Actually I don't think it works that way. Using DC ohms law on AC voltage current and power is not correct. When calculating AC current requirements we should include the power factor (PF) and efficiency (EF) of the circuit. See here: AC Currrent / Power app note Also, remember that all of...

I have always suspected that it might be the electrolytic capacitors drying out in the timing circuitry. As these caps dry, their effective capacitance changes and thus the timing, which might become audible. A lot of CRTs "die" because these caps die, and they are cheap to replace. My theory...

John_F and Eric, All things being equal 1080i displays more information than 720P. Yes it is interlaced, but there are more lines of video information. The difference between progressive and interlaced only deals with the refresh rates of the displayed information. 1080i/p 1080 rows by 1920...
