I tried both, but none can fix the hiccup Image may be NSFW.I couldn't figure out how to get the full 60Hz progressive without the colour artifacts (the NTSC colour system wasn't designed to work with an even number of lines, and the colour carrier frequency and line rates are tightly specified by the standard*) so I decided to give you a choice! I should get around to documenting it...In both cases, the frame rate is exactly what's advertised in the DRM display mode (it wasn't before), so there's not much more I can do about the hiccup. If you've fixed the frame rate at some other value, try setting it to match the mode.
- With that mode above, you'll get 262 lines, static colours, and a frame rate of 60.054Hz.
- But if you increase the last number by 2 (so that the vertical timings add up to a "fake" 526) you'll get 263 lines, phase-flipping colours and a frame rate of 59.826Hz.
(*No such issue for PAL which works happily with 312 lines progressive, and PAL-M with 262 despite lacking the "precision offset". And before anyone jumps in with NTSC-bashing, it was the pioneering standard on which PAL was built; and PAL in its time was quite complicated and patent-encumbered. All history now.)
Clik here to view.
(I tried the mode with more artifacts with RetroArch configured to 60.054hz, which it reports automatically too btw, and also mode with phase flip and setting RA to 59.826Hz.)
On one hand, I feel bad to have made you do all this work... but I am very grateful, as we would not have known if this really was the issue or not unless these tests were made. It will be useful if these 2 modes stay available when/if later something else fixes the hiccup, we'll be able to test with both of these modes to confirm if either one gives hiccups or not.
Should I open an issue on github? Should I make another thread in these forums asking about this?
Thank you!
