Currently I'm dumping traces to the A-F thread simply because I want to get input on what to capture. Once I have good and relevant captures I'll reformat those with analysis and likely post to my own blog - that I can then link here also of courseexxos wrote: ↑Sun Jan 07, 2018 11:01 amCould you please post you scope shots in a thread maybe in member blog section
Also, for those who are not keeping up (me mostly) are you saying during a normal video low output the shifter switches into high res.. Or is that just a trick demos do for some reason ?
When doing fullscreens there are two tricks used. GLUE checks when to start and stop lines (and screen) depending on the resolution, so by carefully switching frequency or resolution at specific points the GLUE either starts lines or end lines at "wrong" (fullscreen!) positions. Additionally, extra words left behind in the Shifter that can screw up alignment on the next line can be "cleared" by going into high or medium resolution and then back to low at the very end of the line. That "stabilizer" is what Smonson and I discussed now
Yeah you should display black when mono is set on an otherwise color line, and you can ignore what happens after the stabilizer has run. Actually, in detail, the stabilizer skips BLANK start and the line is then displayed for a few more pixels until HSYNC kicks in which again means nothing should be displayed from there until BLANK is deasserted on the next line
(The stabilizer is not used to "open" the right border - that's done via a 60/50Hz switch at cycle 376 and is not visible to the Shifter at all)
