I like the prototype on the front page, but I’ve also noticed you only have a singe switch for “on-off” Remember what I asked you about having even/odd fields, because you’ll run into problems where the kit will only scan the incorrect one. I’ve observed this when all I could clearly pick up was the filtering leftovers.
The slide switch is a three way. Odd-Off-Even. You can kinda make out the silkscreen text beside the slider.
Fun fact: its the ‘horizontal with board’ version of the exact same slider used for LS/DP/RS in MadCatz sticks.
I posted the pic’s on the front page of thread and on page 3 with some description details but with so much spam lately its harder to find
Hey Toodles have you received the asus monitor you were going to use do some testing on?
also did you recieve the email I sent you?
Thanks
Ah much nicer than my jury-rigged set up.
Still need to wire it up for SCART though.
Oh and with the Asus monitors I found that mine couldn’t correct the aspect ratio to 4:3 I switched to my other monitor which works fine. Also geometry settings only work on RGBS.
Evo monitor came in, and getting it setup with my Dreamcast VGA box was a cinch. I want to study a few things under an O-scope, but I’m waiting for the vga snooper board I made to come in, about 1 week. I’ll be able to get a good view of how the VGA signals are actually working instead of what I’ve found online. The VSync line for instance I read was usually low, with a high pulse once per frame, but it seems to be the opposite. After I get a peek at how things works on both the Dreamcast and the RGB->YUV board, the sky shoudl be the limit on what I can do with it.
Yes, I’ve gotten a couple of emails from you. Hang on.
You have a purchase from me Marcus once things are said and done. Keep up with the good work.
Let me ask you though, what would you want it to do?
- Compatability: I’ll already be checking this against my DC VGA box, that ebay RGB->VGA converter, and a cheapo Xbox360 VGA cable I just ordered from Amazon. What else do you think it might be used with? VGA output from a JVS system like Naomi? What else?
-Features: Adjustable scanline intensity and adjustable scanline width is already planned. What else could be wanted? Should I do RGB adjustment? (I’d pretty much forgotten about it since the RGB->VGA does it already)
What else can I do or should I do?
How do you like the GBS 8220 scaler not too bad for a cheap scaler of course I’ve never got a chance to try any of the xrgb scaler’s I’m sure it’s a notable upgrade you messed with one the xrgb’s before?
The one thing about RGB pods on the GBS 8220 don’t seem the best even the slightest adjustment looked crappy maybe it me
Not sure if RGB adjustment is necessary, but if it’s easy to implement, it would be cool. A way to quickly over/under saturate an image would be kind of neat, especially if you were interested in trying to replicate CRT color bleed. Sure, scalers can do this, but in the case of the 360, you wouldn’t be using it, and it would save you a trip into the monitor controls.
Definitely make sure it supports a decent range of resolutions, for those of us that would be using it with an emulator setup. 480p/720p/1080p should be a given, but also 1680x1050, 1920x1200, and the dreaded 1366x768 for those afflicted with odd res 32" TVs.
Just a heads up, third party VGA cables for the 360 often have ghosting issues. Take this into account while testing.
I’m not sure if that higher resolution is possible the other scanline generator has been around for while now and 480 is the norm you can’t see the lines at that higher resolution no matter how thick it gets
Well, if it isn’t possible, then so be it, but I figured that the thickness adjustment was hand-in-hand with being able to use higher resolutions.
You desire color bleed?
-ud
Sure. I mean, if you’re trying to emulate a CRT then why not? I’d take pincushion controls too, but that’s asking a bit too much. 
That’s one of the things I was hoping to look into shortly when the vga snoop gets here. Im 90% sure I can add in adjustable scanline widths, black out two rows, leave 2 rows, repeat.Could even do it with 3 or 4 if there was a need. Based on descriptions that >480 resolution causes the lines to disappear and just darken the entire screen, I’d bet the T-SLG is doing its job but the lines are too fine for it to be noticable. As long as the ‘thickness’ is selectable on the board, it still wont have to worry about trying to identify the resolution going through it.
How hard is it to add other outputs? I suppose one could always just buy a vga > DVI / HDMI cable
RGB adjustment for the picture or for the color of the scanlines?
I’d say RGB adjustment isn’t necessary if you aren’t noticing any particular problems in testing. If strange color problems are occurring then throw it on there or just leave it as an option. I think that most people will be using it to go component/composite > VGA
Honestly for me, I’d just like to get rid of this Giant CRT in my room and be able to play my system collection on LCD without it looking like a mess.
it would be better just to get a vga cable for that system The VGA jack on tv or monitor has a separate sound.
There might be adapters to stripe the sound from hdmi but im not sure off hand I would have to check
RGB is a simple add on it will make it look cool and its there if you need it
Most people should use this device with a scaler not componet cables if your going to the trouble of adding scanlines it does’t make sense to not have the best picture before adding them
remember the scaler doubles the lines most old games are on only 240 lines with scaler its 480 LCD’s need the 480 to look good and the scanline generator makes the 480 look more crisp
- I dont know. I’ll look into it.
- Both. The RGB adjustment of the scnalines (what I’ve been calling the scanline intensity) could be done so that the scanlines arent as dark. It seems like they aren’t absolute black, even in the pictures RosserRooster posted. Im hoping the oscope time will help explain that to me so it could be dealt with. The RGB adjustment of the non-scan lines was planned for reduction only (voltage dividers FTW) but Im thinking an increase should be possible as well. So cheapest option: No RGB adjustment. Next cheapest: RGB adjustment down. Mr. Fancypants: RGB adjustment up or down.
