feature request: line4x embedded as 1080p #80

It would be great to have an option on line4x mode which is seen by TV as 1080p. Not every TV works now with line4x mode.

tricky since there's not enough memory to buffer anything. But I wonder if you could use a reduced vertical refresh timing 1080p and just output black lines during retrace on the input signal?

but now line4x has on output 960p -- the point is to add 60 point at top and at the bottom and tag it as 1080p

This is not possible with the current model, you need to wait for upcoming Pro HW which is able to implement this feature.

it's not as simple as "tagging it" dvi is a real time protocol you have to put the pixels out at a specific time and rate that matches the pixels coming in from the console. without a buffer you can't do arbitrary resizing. But that's why I suggested using reduced vertical refresh 1080p on the output side. Then you could use the actual vertical refresh on the input sized to put a black buffer around the top and bottom.
