    Can not adjust Advanced Timing Settings either.

    I think you should make a separate post to get this issue addressed.

    Tried to create an account to add this to the wiki, but looks like it’s private access only.

    Epson PowerLite 8345 projector (8350 should be the same)

    Screen size: 34″ to 308″ (tested at 80″)
    Tested by: Guspaz
    Line x3: No
    Line x3 PAL: No
    480pX2: No
    SNES: Yes
    Latency: 33ms (240p test suite manual)
    Vsync Tolerance: ?

    To clarify, the OSSC itself does work well in Line x2 mode. Tested with NTSC SNES, NTSC PSOne, NTSC NESRGB , NTSC/PAL GameCube (240p/480i), and NTSC Wii (via GARO).

    This one is for those who are trying to use the OSSC for streaming.

    HD RETROVISION modded N64 + SCART + OSSC + ELGATO HD 60 PRO (internal card) With the 3.55mm audio jack plugged into my PC’s line-in works.

    I would love a way to combine the audio into the HDMI cable though to make this simpler.

    The Proofs:

    Line x3: No
    Haven’t messed with any other settings because I’m not really sure how to go about testing them.

    Dell U2711 monitor

    Screen size: 27″
    Tested by: Guspaz
    Line x3: Yes
    Line x3 PAL: Yes
    480pX2: Yes
    SNES: Yes
    Latency: 2 frames (33ms) (side-by-side photo against PVM CRT with 24p test suite auto lag test)
    Vsync Tolerance: ?

    Also tested 480i passthrough and 576i passthrough. They sort of work: image is half height (monitor may be throwing out every other line). It can be forced to the correct height by setting the monitor’s aspect ratio to “fill” instead of the normal “aspect”, correcting for that, but that only really works on 16:9 signals, being a 16:9 screen.

    Acer K272HUL monitor (27″)

    Syncs to almost everything ECS Amiga / OSSC can output including some weird resolutions (OSSC won’t sync to some most exotic modes though):

    240p lineX2: Yes
    240p lineX3: Yes
    480p lineX2: Yes
    480i passthroguh: Yes

    Has some troubles with 60Hz NTSC mode, sometimes won’t sync until I power cycle the OSSC. Also aspect ratio of NTSC x3 mode is wrong (!) while x2 mode is ok, but x2 modes generally (other than NTSC also) has some weird interference in the picture while x3 modes do not. Go figure but at leas for PAL gaming and productivity mode is perfect.

    Ps. OSSC itself has to be adjusted (advanced settings) when using display modes like 640×480 productivity, otherwise image quality is poor.

    You should use generic 4:3 linetriple mode for correct aspect ratio. For some reason a lot of people overlook this (generic 16:9 is default but should only be used when converting back to analog for CRT/PVMs).

    Ah interesting thanks, I’ve overlooked that setting. I’ve been also tweaking advanced timing settings a lot with my Amiga and I can confirm that Acer K272HUL can display just about anything OSSC can throw for it.

    Sony KDL-70R550A

    x2 Works
    x3 Works
    480i Passthru Works
    480p Passthru Works
    480p x2 Works

    Consoles tested so far:
    RGB modded PC Engine Duo-R
    RGB modded N64
    Super NES
    Atari Jaguar
    Genesis 2
    Genesis 2 w/32X*
    Playstation 2**

    *With the 32X attached there were significant jailbars and interference patterns. I did not attempt to make any adjustments to correct it. Removing the 32X improved the image clarity significantly but jailbars and interference were still slightly visible. I suspect this is really a problem with the console, though I do not see these artifacts when connected to a Sony Wega CRT.

    **I used the Gran Turismo 4 to test various display modes, including 480p, 480p X2 and 480i passthru. The 1125i/1080i passthru mode showed no output, however I remember the PS2 1080i mode being squirrelly even on CRT HDTVs so I’m not ready to say the mode doesn’t work with the OSSC. The 480p linedouble mode was detected by the TV as 1440x900p. The aspect ratio was correctly preserved, but the image had a large black border that I could not adjust with the TV’s “zoom” feature.

    Will update as I make my way through my consoles.

    Vizio M70-C3

    Okay, I completely removed the old report because it was based on a firmware several versions old; this report is based on v0.77 on a v1.5 DIY kit.

    Update: Upgraded to v0.78; no changes in compatibility. Added result for Sega Master System.

    Like many of the current crop of 4K TVs, the M70-C3 will perform differently depending on which HDMI port is used. For my testing, I used HDMI5 (the sole 4K@60-enabled port) and HDMI4 (one of the others). I did my actual testing with the OSSC plugged directly into the port being tested, but later confirmed that switching the signal through my AVR (a Denon AVR-S910W) with all the HDMI processing features turned off did not affect stability or lag.

    I did testing using the 240p test suite for both Wii and Dreamcast (the only two consoles I can run it on at the moment), with RGB SCART sources switched through a gscartsw_lite, component through an Impact Acoustics 6/2 switch, and Dreamcast VGA plugged directly into the OSSC. For lag testing, I tested against a Sony PVM-14M4U I managed to get ahold of recently. I made sure to set the monitor up so that, in the frame of the test photos, it roughly matched the height and vertical positioning of the TV in order to avoid the risk of rolling-shutter error.

    HDMI5

    Lag: ~1 Frame
    240p/480i Resync: ~3.3 Seconds

    240p Passthrough: No
    240p x2: Yes
    240p x3: Yes
    240p x4: No
    240p x5: No

    480i Passthrough: No
    480i x2: Yes
    480i x3: No
    480i x4: No

    480p Passthrough: Yes
    480p x2: No

    1080i Passthrough: Yes
    1080i x2: Yes

    Notes: This input is less compatible, but has far less picture processing and lag. Note that there are no scaling options when using this input; 720p and 1080i/p use the full screen, while 480p signals seem to be multiplied to 4x (the maximum integer scale possible) and then windowboxed.

    HDMI4

    Lag: ~3-5 Frames
    240p/480i Resync: ~2.5 Seconds

    240p Passthrough: No
    240p x2: Yes
    240p x3: Yes
    240p x4: Yes
    240p x5: Yes (All Modes)

    480i Passthrough: Yes
    480i x2: Yes
    480i x3: No
    480i x4: No

    480p Passthrough: Yes
    480p x2: No

    1080i Passthrough: Yes
    1080i x2: Yes

    Notes: This input is much more compatible, but also has much more lag and intrusive picture processing. There are a few possible scaling options for a given resolution, supporting both 4:3 and 16:9 games when using a 480i/p console.

    Consoles Tested

    NES (NESRGB – RGB SCART)
    Master System (RGB SCART)
    Genesis (RGB SCART)
    Super Nintendo (RGB SCART)
    PlayStation (RGB SCART)
    Saturn (RGB SCART)
    Nintendo 64 (THS7314 Amp – RGB SCART)
    Dreamcast (Kuro – VGA)
    PlayStation 2 (Component)
    Xbox (Component)
    Wii (Component)

    Other Thoughts

    In general, both inputs were quite stable with signals from the latest firmware version

    While the processing is lighter on HDMI5, it’s not entirely absent. It’s most noticeable in causing the scanlines to seemingly group into pairs of two that have a thin, hard-edged dark line between them and thicker, softer-edged lines on either side. I don’t find it visible from my viewing distance (about 10 feet from the 70″ TV), but if I were a bit closer it would definitely prove annoying.

    Interestingly, when forced to resync, the picture doesn’t return on HDMI5 until around a second after the resolution information is displayed onscreen. When using HDMI4, by contrast, the picture returns at the same time its resolution info appears. This discrepancy appears to account for the shorter resync time when using HDMI4.

    Overall, I’m reasonably pleased with the TV’s compatibility with the OSSC. I’m perfectly happy with linetriple for classic games, while I can bear with the lag to properly scale the 480i/p of later games. While I’d definitely be interested if a good 4K video scaler comes on the market to add to the chain here, as it stands now I’m happy enough with the setup as it is. Since my AVR has dual outputs, I was able to pretty easily set things up so that I can switch between HDMI4 and HDMI5 for the best of both worlds.

    That sound like pretty much ideal scaling for a retro gamer! Shame that linetriple is unreliable then. Did you trouble-shoot this much? Like try different HDMI input, use PC mode, change OSSC TX mode between DVI & HDMI? And it wasn’t OSSC that desync, just the display?

    TVs:

    Panasonic TC-P42UT50B

    240p x2: YES (including SNES!)
    480i passtr: YES

    1080i x2: YES
    
    All the other modes: NO

    Unfortunately nothing changed since firmware 0.76 in this TV. But as a plasma TV I still highly recommend this one for the great response time and almost no blurring effect with fast scroll images compared with LCDs and LEDs. Personally I still prefer this one over the Samsung 4k that I also have, even it supporting very few modes as I showed above.

    OSSC fw. v0.77

    Consoles:

    NTSC Sega Genesis using SCART “raw boosted sync” cable from retro_console_accessories. I get 480i with Sonic 2 (2 players screen) adjusting H-PLL Pre-Coast=3 and H-PLL Post-Coast=3.

    NTSC SNES Mini modded with RGB Amp from retrofixes, using SCART csync cable from retrogamingcables. To get it working flawlessly, I adjust Analog sync LPF=30MHz and H-PLL Pre-Coast=0.

    NTSC Sony PS2 Fat using SCART luma sync cable from retrogamingcables (and also tested with genuine component cable, with same results).

    NTSC Sony PSP 2001 using genuine component cable.

    Woaw, that really sucks! First report of complete linedouble incompatibility. 🙁 And on a Samsung, very surprising. You tried the basic trouble-shooting (outlined in post above yours)? It sounds too bad to be true kinda…

    I did try a few different things, and I found that the linetriple is a fair bit more stable when I run the signal through my AV receiver (a Denon AVR-S910W), though still not what I would call playable for anything action-based. Changing the HDMI Tx mode has no effect at all, and the sync drops are definitely on the digital side of the equation, as I’ve kept an eye on the OSSC during the drops and there’s never so much as a flicker of red from the LEDs. Normal linedouble works fine, which would also rule out an analog sync issue.

    I’ve switched off all the postprocessing features on the TV and AVR and switched them into their respective gaming low-latency modes, but I don’t have a CRT handy to get a good measure of how much lag may still be introduced by the chain. Experimenting with some of the pair’s processing features seemed to improve stability in some cases but worsen it in others, so I ultimately chalked up any improvement to the TV’s handling of the OSSC’s out-of-spec signal just being unpredictable.
