Thank you again KC-Technerd,
Unfortunately I can't use "Normal" on my TV. Either we have a different TV, or different Firmware. If I use Normal my TV puts all sources to a square, something that looks like 4:3 but actually crushes the 16:9 source into a square shape. I tried it on three different PC's, on my WDTV Live, two different Roku's, Three different Bluray Players, one Wetek player, several Chinese Android boxes and now my SHIELD TV. Only "FULL" mode gives me a full 16:9
screen. All other modes do something to the source that is unacceptable, on my TV at least. My service menu is currently on Sony defaults too, and all sources of video are set to 1080p/59.940 or 60Hz. The SHIELD doesn't offer anything but 1080p because it uses only the native resolution of the display it's attached to. For example all resolutions that Youtube sends to the unit is upscaled by the SHIELD itself. My TV doesnt switch resolutions unless I am using either Kodi or some other app that auto switches to the best res. Plex will switch from 59.940Hz to 24Hz (24p) if I play a movie, but it never changes from 1080, unless of course I play a ripped DVD which is so very rare I can't even remember what it does, lol.
And yes I now see the "Normal" you were referring too under Display Area, and yes it has always been on "Normal" in the "Display Area". However, under "Wide Mode" it must be set to "FULL" or I can't use the TV for anything at all. I am on different firmware though, maybe, because Sony sent me a USB drive many years ago for some reason and I updated the Firmware with it, lol.
Anyway I put the service menu back to defaults because you said this was 1:1. Unless 1:1 is dependant on "Wide Mode>Normal" then I can't use it because that produces a nearly foot wide black bars on the sides, as seen in the below images.
Your recommended "Normal" mode. The tips of the green arrows represent the very edge of all 1080 source output which is currently outputting 1080p/59.940.
The "Full" mode I have been using.
Have any idea why ours is different? And do you think my FULL is 1:1? Thanks for all the input buddy, really nice to see someone still around sharing knowledge and ideas on such an old set. Thank you for that.
