    * Added support for PCM1862 audio ADC (pcb v1.6)
    * Added “Allow upsample2x” option to replace pixel repetition in certain modes
    * Enabled line2x selection for 640×512 (X68k)
    * A number of minor bugfixes

    Can you elaborate on a scenario where this would be helpful?

    * A number of minor bugfixes

    Just wondering if you can provide the details. I’m a thorough guy in my testing so I’m just curious if any of the minor bugs fixed are things I might’ve encountered. 🙂

    For upsample2x, see wiki and this thread for details.

    Bugfixes include disabling scanlines in 480p auto mode, removal of 3x/4x processing options from 1080i mode (inoperable, weren’t meant to be there in the first place) and fixing occasional pixel repetion issue after HDMI< ->DVI TX switch.

    Thank you!!!!!!!!

    Yet again, I have to wonder: Would it be possible to implement a full 1920 pixel sampling and output for ALL input resolutions, not just for 240p/280p? Besides enabling maximum picture quality, this would allow for easy aspect ratio correction (just map the 1440 pixels upsample2x gives you to the 1920 pixels), which is THE ONE feature the OSSC lacks in my opinion.

    I mean… I’ve been trying to find a good all-purpose monitor for quite some time now. Every single monitor I’ve encountered so far was able to stretch arbitrary resolutions to full screen (16:9); however, only a select few monitors were able to display resolutions like 1440×480 or 1440×980 in 4:3. I don’t know how TVs fare in this regard, but I wouldn’t wonder if some models failed here as well.
    Implementing what I described above would solve this problem once and for all.

    So… PLEASE?

    As a PC monitor user myself, I heartly second Thomago’s request. 🙂

    You should post that in the feature request forum but it seems to me that you just need a 4:3 image inside a 16:9 frame feature like lineX3 and X5 can do because with upsample2x full 1920 is now possible in every input resolution.

    It’s indeed possible (I tried it), but involves a bunch of tinkering with the Sampling settings. As 1920x[whatever] output would be ubiquitously useful, it should really come preimplemented.
    Besides, judging from my findings without upsample2x, forcing 1920 output via the Sampling settings probably isn’t the same as having actual 1920 pixel sampling.

    Update made my capture card compatible with 240p linex4 and 480p linex2. That’s awesome! But…. it made it not compatible with 480i passthrough 🙁 It doesn’t say no signal like it normally would if it wasn’t registering it, it just shows a black screen. Kinda need this to work, guess I have to revert back to 7.7

    Edit: Seems that reverting back to 7.7 doesn’t fix this issue. Normally switching to HDMI TX mode would make it work, but now it’s just a black screen.
