Kodi Video Calibration to perform at each reboot

[f1vefour]

All TVs aren't created equal, trust me I know how to setup my TV and KODI. This isn't just with a Raspberry, my PS3 and Odroids are the same way except the PS3 automatically sets the correct overscan.

My TV reports a lot of available resolutions and hz, such as 1920x1080@24hz...etc. When in any mode other than native resolution all display adjustments are available, it has to do with using the display as a PC monitor where you don't want dynamic contrast and such since the PC will have it's own adjustments. Most video sources (PS3, BluRay players...etc) will automatically select 720p and not 768p which is the native resolution and what a PC would select, but Pi's and such are like PC's and by default select the native 768p but have no extra display control features like real PC's (other than size adjustment).

I understand why my TV behaves this way, I don't agree with it but I understand it. Obviously something is screwy with most display sources such as the Pi because I need no adjustment with the PS3. I select 1080p on the PS3 and I have a perfectly aligned display, I select 1080p on the Pi in KODI and I have to 'shrink' the picture in KODI because it doesn't display properly. This is some type of issue with cheap HDMI sources such as the Raspberry Pi, like I said on the PS3 it works as it should.

I can do like you Richard and disable overscan in the TV menu and all resolutions will display correctly, but what the TV is doing when I disable overscan is essentially kicking the resolution to native 768p (1366x768 PC mode) and disabling dynamic contrast, sharpness, and contrast adjustment. Stupid but true.

I will go a bit further and explain PC mode, PC mode disables all extra video processing to give you the fastest possible display, no video processing on the TV gives lower latencies which affect how you perceive mouse movement and doing things such as playing games where low latencies are necessary.
