turning off lots of the menu setting can help, if your tv
has a 'noise reduction' setting like my sxrd leave that on.
It maybe part direcTV box, because before I got my tv I went to BB & had them show me what SD looks & they where using Hd directv box. The image was sooo bad, almost unwatchable. When I did get the tv & hooked up my SXRD to a SD dishnetwork DVR Box, the tv looked almost same good as it did on my Sony HD CRT did.
& now the CRT TV is in another room hooking up to a SD NONE dvr dishnetwork box & the setting are the same when I had it & now it looks much worse. The DVR box has a better processor.
LCD tvs' are the worse at handling SD.
& NO channels are NOT going HD, just digital there is a BIG diffrence. Since you have DirecTV that will not affect that part of your TV life since that is a Digital signal Now anyway. If you use an OTA antenna that is where the changes will be seen the most.
I am having trouble viewing SD channels on my Magnavox 42" LCD HDTV. I am using the Directv SD receiver/DVR.
I just went over to Radio Shack at lunch. The salesperson there was nice enough to show me all of his LCD sets on both HD and on SD channels. All channels were coming through a Dish Network HD receiver and HDMI cabling.
The SD channels looked just as bad on all of his LCD sets as they do on my Magnavox 42" LCD. He told me that it was going to be like that until everything gets into HD. So, if all of his display sets looked grainy and unclear on SD channels, is there anything at all that I can do to improve my picture quality on SD signals? I had considered upgrading to the Directv HD receiver with HDMI cabling, but based on what he showed me, that will not help.
