New Scanline generator SLG3000 - available now!

[bencao74]

- Is it correct that the potentionmeter's stick does not have the rond knob attached that I see on photos.

Jap , this is correct.

- Does the SLG 3000 only support scanlines on the resolutions mentioned? I'd like to use a 16-9 resolution that the HD Box Pro can supply.

Most sence makes SLG of course with 480p. But which resolution do you want to run?

- Is it correct that I do not see scanlines whatsoever and the potentionmeter only has some effect on the pictures brightness? Also, the on/off switch made the picture bright (on) vs dull (off).

Do yo try to run a resolution where you barely do not recognise the scanlines. Make a test run with 480p. Check the dip settings...

...on my HP w2207...

Are you using a res of 1050p (namely 1680x1050 in 16:10) ? I don't think that'd be a wise option for the SLG, I'm not even sure if you'll see any scanlines whatsoever at that res.
Jochen?

[bencao74]

I can try at my setup, but I doubt...

[jelbo]

Thanks for your help guys.

I'm trying 1050p yes. That does indeed not make much sense, so I switched to 480p on my HD Box Pro. I'm using a PSP 2000 that outputs 480p (selected Progressive, not Interlaced). DIP4 On, DIP5 Off or the other way around, still no go; no scanlines. Potentionmeter only has effect on brightness. The on/off switch didn't do anything this time, except a short flash of brightness increase when turning it On (towards the SLG 3000 logo).

My HP w2207 does stretch the image to full screen (it's a 1680x1050 native), but I can select 'scale to aspect ratio' from the OSD. That makes the image smaller, but still no scanlines.

I guess my HP w2207 is causing all of this? WIll have to try on another screen.

When the potentiometer affects just the brightness and not scanlines can be seen, the the VGA output's sync polarity doesn't match. Since I have used the HDBoxPro with the SLG3000 before (and so have others) that shouldn't be the case.

Make sure to try all four possible dip switch settings (on/on, off/off, on/off and off/on).

Interesting. I've just tried all possible dip switch settings and the only thing I see changing is when I put both On, the bightness is increased. Could it be my VGA cable? One of the connected ones lay around and has never been used before. Maybe it has a different polarity (sounds kinda stupid )?

[fagin]

I doubt it would be your VGA cable as the polarity comes from the source device... i.e. your scaler. Switch 4 should be OFF and Switch 5 should be ON for a 480p source with expected polarity (alternate this setting to alternate the scanlines - odd to even (or whatever way round it is)).

What is your output res of the HDBOXPRO.... makes sure it is 640x480.

[KBZ]

been getting some strange behaviour on mine using ps2 w/ cga2vga and Dreamcast vga..

http://i3.photobucket.com/albums/y85/k1 ... G_1709.jpg

tried each dip setting, various games, different vga cables, changes slightly but never to anything resembling scanlines.

am I missing something?

[fagin]

What specific scaler are you using?

[KBZ]

it shows up with or without it, but it's this one. A few people have posted good results using it with the SGL

[fagin]

OK... how are you connecting your PS2. Is this via component? What is your resolution output on the CGA to VGA Scaler... it should be 640x480, and if so your dipswitch settings should be ON ON ON OFF ON on the SLG. Finally what type of native resolution (720p or 1080p) is your screen?

[KBZ]

I get the same image when I'm using the Dreamcast's vga output @ 640x480. My LCD is 1080p natively.

It's a v2 so I only have the two dip switches, tried every orientation and no go.

[bencao74]

never saw this strange glitches. Could you check your cables? Nevertheless, pmed.

Hi all, I've got a problem with a SLG3000, but only in combination with my Xbox 360 and Sega Blast City cab.

I have the following set-up:

- Xbox 360 with VGA connected to the video input port of the SLG3000
- Another VGA cable connected to the video output port of the SLG3000, the other side of the VGA cable is hooked up to the VGA connector of the Blast City cab

When I turn everything on it works fine for a few minutes, and the image is crystal clear, but after that the screen starts flickering like crazy. I've made a youtube movie:

http://www.youtube.com/watch?v=2DbYO1dWaV4

- I've tried all possible dip switch combinations
- turned the potentiometers
- the Xbox 360 is set on 640 x 480
- I've tried two different VGA cables
- without the SLG3000, the Xbox 360 works perfectly fine on the Blast
- It's manual sync Blast City monitor
- Without the SLG3000 the setup works 100% perfect, but no glorious scanlines

- When the dip switches 4 and 5 (both) are down (set off), there is no flickering and a relatively stable image, but the screen is "vibrating" a little.

What could the problem be? Am I missing something?

[fagin]

It shouldn't need it but try powering the SLG with a 5v supply.

Looks like a sync issue.

Quick update on the HDFury2 situation, so I tried transcoding PS3 > HDFury2 via Component > X-Select > SLG3000 -- it shows 480p scanlines perfectly with no polarity issue. So I tried PS3 > HDFury2 via VGA > X-Select > SLG3000, to see if the X-Select was the factor here but had the same problem. Picked up another Fury1 and it works perfectly with all resolutions.

I suspect it is the fact that the transcoding from Component to VGA that is "sorting" the polarity issue out rather than a X-Select specifically.

What is your output res of the HDBOXPRO.... makes sure it is 640x480.

Well, it's set to 640x480 and my PSP to 4:3 and Progressive. I'll have to wait for my component cables to arrive from Hong Kong to test it with my Wii..

Sounds very strange..... the only other thing worth trying is to power the SLG with a 5v supply, but in all honesty whilst it would be worth trying I can't see this solving the problem. As Fudoh says (and as I have experienced on a number of occasions with other scalers) this appears to be a sync polarity issue from your scaler. I have never tried a HDBOXPRO so can't comment. Logic suggests that it will make no difference what your video source is (Wii or PS2)... the results will be the same I suspect, as it's the scaler that would be causing a sync polarity change.

If you have the ability..... take a VGA output from a PC (640x480), Dreamcast or XBOX360 (640x480) and see if you can get scanlines on your monitor without the scaler. That will at least tell you if it is a scaler problem (I suspect it is).

Okay, I just hooked it up on my pc using a DVI>VGA converter that came with my videocard. Set the 'extended display' to 640x480@60Hz and my w2207 to 'Fill to Aspect Ratio'. I then tried all possible dip combinations. Still no scanlines.

/EDIT: I've got scanlines now. I mixed up the on/off position of the SLG switch. Will try with my HD Box Pro now.

I don't know how to power the SLG but will try using a different VGA cable tomorrow.

I do hope the SLG will be able to put scanlines on a 1680x1050 or 1920x1080 signal though, because I bought one to use with my Wii.

[SGGG2]

1080p scanlines are hardly noticeable and has a softening effect. Try 720 scanlines instead.

Err, the Wii has a maximum resolution of 480p. I wouldn't scale it beyond that if you intend to use the SLG with it.

Hello!

I received my SLG3000 v2 yesterday, and finally got a chance to hook it up with my Dreamcast tonight.

Unfortunately, I'm not seeing any scanlines.

I have a working VGA box, going to a 37" Samsung. All works perfectly with no SLG 3000 in between VGA leads.

Adding the SLG3000, the picture still appears, no problem, and is just as clear. However, no matter what position I turn the dial to, or flip the dip switch setting to (4 on, 5 off is what the guide says for 640x480 yeah?), the picture does not alter at all. Not even a flicker. And yes, the main switch is in the on position!

Am I missing anything? Seems like the box is faulty so far…

[bencao74]

seems to be an issue on v2. I`ve reproduced the same setting with Dreamcast VGA Box and got the same results. I`m working on solution right now. A external PSU should do the job anyway. But anyway, this should not happen. If you encounter this problem on your unit get in touch with me.

[bencao74]

found the error. It was a wrong IC, this little 14 pin thing on the PCB. My supplier somehow managemed to send me not the low power version. Some devices like Dreamcast VGA Box doesn't supply enough power for the IC standard version. My test equipment was working with this standard IC well, ie. xbox360.

I´ve re-ordered the low power version of the IC and I do of course an cost free exchange for those who have this faulty chip. Get in touch with me per PM or mail.

[jfs]

ok cause i ve the same pb with my dreamcast+vga box.

[bencao74]

Yes, pb is reproducable and solution is found. So, I hope you got my mail?

[jelbo]

I'm glad you've found the error. I'll get in touch with you about the fix.

Hi - I'm not exactly the most regular of posters, but I have been lurking in this thread. Just have a quick question about this device.

I'm intending to purchase one of these primarily for use with the Dreamcast, using a Blaze-branded VGA box. Does the above-mentioned problem with using the device with the Dreamcast affect all v2 devices? If so, should I wait a little while before ordering one? I won't be back in the UK until August anyway, so I don't necessarily need it right away.

Thanks in advance!

[bencao74]

Hey,

I received today the low power version IC. All delivered v2 will be exchanged.

All upcoming units will be assembled with the low power IC.

So SLG3000 v2 is not affected anymore by the above described problem. Even the last wirefix is solved by the new used IC.
