This TV is not recommended for connection to an analog cable box because the TV must convert the analog signal to digital before displaying the actual picture on the TV screen. This extra processing step results in a "lag" which creates a "slight blur" during scene changes and/or movement (e.g. people walking, cars moving, etc.). Also, black and white movies/shows appear to have a distinct green tint (e.g. low-light misadjustment) and this misadjustment also affects how colors are reproduced during a color broadcast (e.g. creating bright but unnatural colors). This misadjustment may be intended by the manufacturer to create more brilliant colors; however, for those that like a green bottle to be green, may be disappointed when the bottle color is reproduced as turquoise. However, on the positive side it does have a digital tuner and it should be capable of receiving "over the air digital signals in the near future." A final word of caution about using a cable box with this set is that a Comcast digital cable box outputs an analog signal if you use the 75 ohm coaxial connection a
nd/or the RCA component outputs (see my caution in the first sentence). Lastly, some websites state that this TV is HDTV ready but I will tell you it is not and it would be a waste of time (in my opinion) to try and use the "composite outputs" of your cable box to improve the picture quality (e.g., stop the blurring). For your reference, I spent 5 years in the TV repair profession before changing career paths to become a telecom hardware engineer for the past 35 years.
