Reply To: BBC Micro Display Settings
To be honest I spend a lot of time on it using command line.. so I was really hoping I could clean up the display.. (I’ve confirmed the OSSC unit is in fact a v1.6).. I was wondering if I could clean up the CLI display…
I am not sure what the BBC is outputing, I think you can change outputs depending on the BBC Mode…
I’ve “copy pasted” something I was following on stardot.. I am hoping this helps;
********************
Firstly set *TV 0,1 – This sets Modes 0-6 to output as 288p instead of 576i. This allows the OSSC to tell the difference between the two video sources.
Go to the output options menu of OSSC, set 240p/288p to Line 2X and 480i/576i to Passthrough. The other options don’t really matter as the beeb won’t generate these modes. This will cause OSSC to output 720x576p50 for modes 0-6 and 720x567i25 for mode 7. These are perfectly standard and very compatible video modes which work fine with both my monitor and my (incredibly finicky) Elgato HD60S capture card.
MODE 0, then in OSSC -> Sampling Options -> Adv Settings:
H. samplerate: 1024
H. synclen: 126
H. backporch: 80
H. active: 720
V. synclen: 2
V. backporch: 15
V. active 288
Exit completely out of the OSSC menu, MODE 7, then OSSC -> Sampling Options -> Adv Settings:
H. samplerate: 1024
H. synclen: 126
H. backporch: 108
H. active: 720
V. synclen: 1
V. backporch: 13
V. active: 288
******************************
If I use this on my device, I get a blank screen and “No Signal”.. I think I can turn interlacing on and off using a command on the BBC… *TV 0,0 turns it on.. I think.. reading that.. I have set *TV 0,1 at the moment.. but I can check that..
