My last question is, if I put a normally 480i channel on, but set it to 1080i will it upconvert it to a better picture? (trying to decide whether or not to use the auto feature)]]> http://www.dslreports.com/forum/remark,20447880 Wed, 07 May 2008 19:29:03 EDT http://www.dslreports.com/forum/remark,20447584 BSD24 : Sorry for the delay -

as some others previously said, you probably need to perform the SA Explorer HD Setup. To launch the HD Setup Wizard, press the "INFO" and "GUIDE" buttons directly on the cable box (at the same time) while the cable box is OFF. The TV should be left ON while you do this.

It should come up as "TV Connection Set-up"
and you would hit the "B" labeled key on your remote to use HDTV mode.

Then it should say "Setup Options"
"A" button for easy setup
"B" for advanced
**USE THE "B" option so that you can change it out of 1080i

Once you go into Advanced setup, choose 16:9 for widescreen and follow the instructions. Pay attention to the bottom of the screen where the different formats (480, 720, etc..) are listed. The ones that have a blank dot are NOT ENABLED the ones with a green dot ARE ENABLED. As you go thru the steps it will test each one and you will tell the box which ones you can see. The box will enable and put a green dot next to the ones you tell it you can see. Be patient, as it will go thru each one at a time.

Once you are done selecting the formats press "EXIT" and then "POWER" and then try the quick settings when you go to the HD Channel you want to change, and you will find the picture format, same thing for the main menu. (See my previous posts)

Not on the remote. Sorry, should have clarified that.]]> http://www.dslreports.com/forum/remark,20447151 Wed, 07 May 2008 17:06:56 EDT http://www.dslreports.com/forum/remark,20447005 anon : meskinct -

I tried turning off the box, and leaving on the TV, but when I press "Guide and Info" at the same time, nothing happens. The remote doesn't even light up like when I press other keys. However there is an "Auto DVI" setting in the main menu which puts "auto" on the box. I selected that setting, and when to a channel that should be 480i and it still displayed 1080i. I went around to a bunch of other channels, and even though AUTO is displayed, the box showed 1080i for every channel.

Thanks to everyone whose trying to help me!]]> http://www.dslreports.com/forum/remark,20447005 Wed, 07 May 2008 16:42:10 EDT http://www.dslreports.com/forum/remark,20446963 anon : Bryan -

I went into the second set of menus, and I found the "set - picture format" but the only options available for that were "Fixed, Auto DVI, Up-Convert 1, and Up-Convert 2. If I select any of those settings besides FIXED, the box displays "AUTO" next to 1080i. However, I did not see any option for "Pass-Through" within that menu.

I looked in the quick menu and couldn't find anything of the sort with the different resolutions like 1080i, 720p, 480i, or 480p.]]> http://www.dslreports.com/forum/remark,20446944 Wed, 07 May 2008 16:33:09 EDT http://www.dslreports.com/forum/remark,20446809 meskinct : First make sure you go through the proper HDTV setup Wizard on the 4250HDC.

With the STB power off and TV on, press the guide and info keys at the same time. Follow the instructions on the screen.

Next, hit menu twice on the remote. Scroll to 'set: Picture format'. Select Auto DVI.

This should allow the box to pass through whatever the broadcast source content is. So if it's 720P you should see the display on the STB change to 720P. Same for 1080i and 480i.

Note: You may have to set the zoom level once and once only when you first change these settings (simply by hitting the HD Zoom button on the remote).

What you would then want to do in that case is hit "Menu" button again to go to "General Settings" and scroll down till you see "Set:Picture Format" and change that to "Pass-Through". Then go back to quick menu once your on the program/channel and change the "Picture Format" which will have the 720p/1080i. Most sports channels actually broadcast in 720p anyways so setting to 720p will probably enhance the picture, and changing it over to Pass-Through should automatically change to 720p when the channel/broadcaster is broadcasting in 720p.

Good luck! :)

What you want to first see if you can do is, hit the menu button once, which should bring up your "Quick Menu" options, look for 1080i, 720p, 480p, or 480i. If you see that then you can attempt to highlight and use your left/right arrow keys to change. If not, let me know. :)

My question is, on the reciever, it shows above the clock "1080i". My television set is a 1080i / 720P set, but I'm wondering how to go back and forwth between 1080i and 720P. Sometimes sporting events look better on progressive scan because of the motion, and I would like to switch between the two.

Any help would be greatly appreciated!!
