I did get around to testing my SNES and noticed it worked in each setting, but had some issues with sync. I’m not entirely familiar with all the terminology but I noticed an intermittent “screen tear” that might be fixable through tweaking settings. I’ll have to play around with it more. If anyone has any pointers, please throw them my way.

Try setting Analog sync LPF=30MHz and H-PLL Pre-Coast=0

Updated my report!

My Panasonic TC-P42UT50B still the same (no x3 or higher)… :/

But my Samsung UN40KU6300GXZD, as @virsago already reported, got work directly, no need anymore to be hooked in the Onkyo receiver! When I updated, the first thing I made is change to “on” the HDMI ITC function, not tried yet to put it “off” to see if have any difference. I’ll do it when I get at home.
Also, SNES fully working without sync problems! IN ALL MODES!!!

Please @Harrumph, update the fist page.

@virsago
Oh, that’s too bad. :/
Not sure if will make any difference, but the last thing I would try in your case is to use a RGB SCART cable instead of the HD Retrovision component. But try to borrow from a friend first, just for test, to avoid spending money in case of unsuccess.

@arovane
Your TV supports the follow resolutions:

  Signal name    Horizontal frequency (kHz)    Vertical Frequency (Hz)

640x480 @60Hz            31.47                         60.00
1280X720 @60Hz           45.00                         60.00
1920X1080 @60Hz          67.50                         60.00

If you try to tweak the OSSC, I think you should base on this.
Here the manual of the Panasonic TX-P55VT50Y. See page 115.
Hope it helps.

Same thin effect happens with 480p X2.
Adding extra(s) scanline(s) would be very appreciated. Even more if we could adjust intensity of each one separately as paulb_nl suggested.

One more vote for that! 🙂

[destinydoom]

Oh, never mind… Now I know that’s possible to flash OSSC from any firmware to any firmware. Maybe will be useful post this info on wiki.

@virsago
I found a workarond solution with my home theater. I updated my post, please see again.
Please post your TV model and everything you tried to do, so Harrumph can put in the list.

@Harrumph
Since I updated my post with a lot detailed information, I was thinking if I could split the post, letting the already created post only for Samsung model, and creating another one for Panasonic, so everything will be less confused. What you think? Please let me know.

[destinydoom]

Nice improvements! Thanks for your efforts!
But I have a question, and guess other people have same doubt: My OSSC firmware is 0.73, can I update directly to 0.75, or firstly I must go to the 0.74 version?

[destinydoom]

Last thing I would try (maybe you did already) is connect to the HDMI (DVI) input and manually rename the port to PC (as described under “Editing external devices”).

Yes, I also tried this and nothing changed. Unfortunately this option is just for ease identification of the ports, nothing related with resolution or aspect.

Detects input as interlaced, that really very weird…

Indeed … Now I am just putting my hopes on the new lineX features on future OSSC firmware update. Maybe this can solve the incompatibility.

@Harrumph

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…

Yeah, it’s a shame … And yes, I tried some adjustments on OSSC and TV, but without results (see the report post, I edited it).
Thanks for your attention, mate!

TVs:

– Panasonic TC-P42UT50B

240p x2: YES (including SNES!)
480i passtr: YES
480i x2: YES
480p passtr: YES
1080i 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.

_____________________________________________________________________________________

– SAMSUNG UN40KU6300GXZD (4k)

Most of the modes works now in this TV (including SNES fully working!). Here the exceptions:

480i in Line3x (laced)
1080i in Line3x (laced) and Line4x (bob)

No need Onkyo receiver anymore, works directly on HDMI port of the TV.

TV firmware version at the moment: 1169

OSSC fw. v0.77

Consoles:
