Frequently Asked Questions
How do I format and select the best picture format and size for my HDTV with my Explorer 3250HD set-top box?
The answers are in the Explorer HDTV Setup Wizard Guide found in the User Guide section of the Explorer eClub.
Why are all my programs displayed in 1080i format?
You may have selected the Easy Setup mode and the Widescreen (16:9) TV setting in the HDTV Setup Wizard. Choosing these two settings together limits your programming to 1080i format, even on non-HD channels. To see your non-HD programs in 480i on a widescreen HDTV, use the Advanced Setup in the Explorer HDTV Setup Wizard. Make sure that you select 480i as one of your saved formats, and then select Pass-Through in General Settings: Picture Format for your default picture format.
Are local TV stations broadcasting in HDTV?
Many local TV stations are transmitting digital signals. However, transmitting a digital signal does not mean transmitting an HDTV signal. Some stations are using the new bandwidth to broadcast several standard-definition channels. Most stations, however, once they begin broadcasting in digital, or offering HD content from their parent network (for example: CBS, ABC, NBC, FOX, WB, UPN, and PBS).
Why are some HDTVs 4:3 aspect ratio and others 16:9?
The aspect ratios differ because television manufacturers build both standard and widescreen HDTVs to appeal to consumer viewing preferences. On widescreen HDTVs, the programming is displayed on the full screen. On standard screen HDTVs, the programming is displayed in letterbox format in the middle of the screen (there are bars surrounding the picture).
