OSSC (DIY video digitizer & scandoubler)

[sk8er000]

I've just tried the new fw 0.71 my Samsung TV supports the 480p/576p line X2 mode but when doubled the colors lose saturation.
Unfortunately I wasn't able to get this mode to work with the vp50 (hdcp off and cadence off) I only get a blue screen like when there is no source, anyone knows how to fix this?
I've also noticed that scanlines in 480p/576p line X2 mode are very very thin. Anyway I understand that having scanlines in 480p games is not really important.

VGA support via passive adapters is part of the DisplayPort spec (look for the DP++ logo). The adapters cost around $10.

Are you sure? I don't see anything about analog RGBHV in either the DisplayPort specs or the DisplayPort Dual-Mode Standard. As far as I can tell, DP++ only signifies that the port can switch to DVI/HDMI-compatible TMDS signalling.

[Fudoh]

I think it's some kind of optional support using the DP connector when the graphics card offers a ramdac to support VGA in the first place. I remember to have used a dirt cheap Mini-DP to VGA adapter a few years ago. Considering the price I guess it was just a passive adapter, so the video module probably supported VGA on its own. But I totally agree: VGA through DP is quite a mystery.

So have emails been sent for the new boards? I'm getting the newsletter, but just want to make sure I did not miss the email to order the unit.

I got my email yesterday. So, I assume they've gone out.

What were you number position on the waiting list ?
I'm 14 on this list and I haven't received the mail

I think i was number 47 on the list and havent received an email either as of yet

Was there (or, is there) a way to determine your position on the list? We're talking about the waiting list at videogameperfection.com, right?

480x2 doesn't work on a VP50

Not that I really care since I can't think of many 480p titles I would want line doubled, but I'm guessing that makes 240x4 working pretty unlikely too.

Same results on my Panasonic plasma, works pretty well on my HP test monitor, but it gets the aspect ratio wrong.

Yai for 480i passthrough though, really simplifies my setup.

I should be in the first batch, but I don't feel comfortable giving more than that here. Feel free to PM.

I just ordered two HDMI to VGA adapters to see if that improves compatibility any. I doubt it, but they could be handy to have anyway.

We know it's a thing of old monitors, and an unknown number of more recent ones. 960p output is kind of a gift to the owners of those.
For everyone else including home cinema scalers users it'll likely never work.

Yeah, line-doubling 480p is a big deal for me on a PC CRT. Will make Dreamcast through Wii games look a lot better

Anyone tried 960p on a modern LCD monitor yet?

My HP monitor is from 2008. While it's not that modern, I doubt newer DVI monitors support less modes.

[Xyga]

Many modern monitors also don't have a DVI in, and don't have 960p modes listed. If it works it might be as a 'hidden' compatibility mode, it depends completely on what the built-in scaler an/or manufacturer allow or not.

I actually missed you saying your monitor worked, that's on me.

Thinking it's likely my monitor will work out fine. Still doesn't stop me from worrying, though lol.

As an example of products, passive converter:

https://www.monoprice.com/product?p_id=5107

Active converter:

https://www.monoprice.com/productp_id=12785

It's entirely possible that they are both active adapters, and that Monoprice has mislabeled them, so what we might actually have there is that what they call a passive adapter is actually a DVI-to-VGA adapter using DP++, while what they call an active adapter is actually DP-to-VGA. That would follow with the specs on the products that say the passive adapter only works with DP++.

The DisplayPort 1.1a standard (the last version available for free) does have a few minor references to VGA (in terms of a bit indicating a downstream analog VGA sink is present), but I don't know what later specs included. VESA's DisplayPort FAQ, though, does make repeated references to adapters, and at least one question specifically states that the adapters are part of a DisplayPort spec (specifically the question regarding adapters from DP-over-USB-C):

Q. How can I use my existing display or digital TV set with a new computer that has a DisplayPort output?

A. DisplayPort has the unique ability to support external display adapters. The DisplayPort Source device (such as a notebook computer) provides power at the DisplayPort plug to power such an adapter, and it detects the type of adapter connected, as well as the type of monitor. Inexpensive DisplayPort adapters are readily available for VGA, DVI, and HDMI displays. Adapters for HDMI 2.0 will become available in the near future.

Q: Does DisplayPort 1.4 still support adapters to VGA, DVI and HDMI?

A: Yes.

Q: Can I connect an existing monitor to a new computer, tablet or phone that uses the USB Type-C connector with DisplayPort over USB-C?

A: Yes. Adapters and Adapter cables, as defined in the DisplayPort Alt Mode for USB Type-C Standard, are available to connect DisplayPort over USB-C to DisplayPort, HDMI, DVI, and VGA monitor inputs.

It seems like I'm in the first 100 so I'd be getting a board without the audio stuff on it? Is there any link or guide for the audio mod?

[sk8er000]

I've got a 2015 Samsung TV and 960p works well, there's only a saturation loss on the colors.
Unfortunately not working on the VP50

Worked fine with NEC 1990SXi and PA272W, and probably with several other PC monitors too. Strange that VP50 doesn't accept the mode - maybe somebody with VP50 could try tweaking the modelines (starting from sync/porch widths) listed a few pages back and figure out which property breaks support. It should at least accept VESA 1280x960@60Hz - right?

[NormalFish]

sounds like my optimism about 960p compatibility (at least with PC monitors) was reasonable. Good to hear.

[karma_police]

Has anyone else gotten emails for ordering? I believe I'm part of this next order of 100, but unlike some of the others on here have not received an email.

[eric90000]

I wonder how many people on this round of the waiting list either won't purchase, or simply not see their email within 48 hours.....maybe people further than 100 on the list might get a chance to buy this time?

I got an email on Sunday. Other than double checking your position in the newsletter the only thing I can suggest is to check your spam folder.

I've read that some other users have issue with the 960p mode with vp50 also for me is quite strange.
If can be helpful I can post my TV's model, for now it support's the 240p/288p x3 mode and 480p/576p x2 mode.

Could anyone explain me this photo?



I usually have from 2 to 4 frames of lag with the mini or the ossc + vp50 compared to my CRTs.
I figured that I've never made a test lag with ossc only so I had a try and the frames are lower than in the CRT?!?!
I have 2 outputs from every kind of source because I use shinybows with 2 outputs.
For this test I've taken the rgbs signal from the output of my bvm so the ossc it's even after the bvm in my chain for this test:

SNES mini-->shinybow 6x2-->converter from scart to rgbs with stripper --> pvm 20lmd --> bvm 20f1e --> ossc-->LCD

I'm a bit confused

[fafangus]

Maybe stupid question but, does anyone already tested the OSSC with a Xcapture1 ? (or other capture card like this)
Doesn't capture cards will accept more resolutions than classics tv or HC sets ? (depend of the card itself)
OSSC (X2/X3/X4) > Capture Card > PC 1080p/4k

[blizzz]

@sk8er000 You're using an old version of the 240p test suite that has a bug. That's why both 1 and 5 are red. You should also lower the exposure time.

@fafangus Yes, you could do that. But then you add lag from your capture card + desktop composition, which defeats the purpose of the OSSC (both input lag and price).

Thank you for the answer I'll try with a newer version of 240p test suite
