In effect, yes this is what he was doing. I’m not 100% sure but I think his motivation might have been to get extra usable pixels for the content by sacrificing the overscan safe area. If that wasn’t his primary motivation then it at least would have been a positive side effect.
I’d like to be able to use his exact overscale (overscan) percentage in HSM Mega Bezel and if possible use this same percentage at other resolutions.
I was thinking that I could use one of these settings or even the cropping settings to achieve this but what I was thinking and asking about was having specific common overscan amounts predefined for simplicity sake as a shader parameter or even as a comment or recommendation instead of my arbitrary overscan settings.
That’s why I started by using @Nesguy’s overscan settings as a reference since I trust his expertise and experience in this area.
If left up to me to determine overscan settings, I’d probably be guessing and just winging it - which is what I was attempting to do with @soqueroeu’s TV Backgrounds.
Ultimately I would want to have and be able to implement accurate overscan settings that will allow content to be displayed more like certain actual CRT models or at least be able to setup common overscan percentages as a sort of lowest common denominator that should work well with most games per core or CRT model simulation (overlay).
If I find or create one I’ll post it.
So to summarize, just as we have LUTs and other presets matching different TV brands, maybe we can also have overscan settings as a subset of the current overscan settings but with percentages that match common brands of TVs as presets.
For example if Sony TVs typically had 3% overscan then we could have a 3% overscan setting called “Sony Overscan”.
If Phillips used 2% overscan then we could have a 2% overscan setting called “Phillips Overscan” e.t.c.
The current default behaviour would have the viewport automatically scale to the edges of the bezel with no overscan or have the user set overscan settings manually based on their own knowledge or methodology.
What I propose is having some friendly overscan settings so that anyone playing can flip a switch and have the viewport match the overscan settings of some common TV brands. So it’s just an extension of the realism and immersion that HSM Mega Bezel brings and an expansion of its ease of use.
