LCD with converter to a Sega Virtua Racing - question

OK, so a fellow gave me his game to throw an LCD tv in on his virtua racing, got the game to sync right away, as the game appears to have just a composite sync wire and a ground for the monitor. The ground does nothing when hooked up really, makes the screen bright, my issue is the following photo, see the dark trace lines on the right of every image? I cant get this to go away no matter how hard I try in menu on the converter or menu on the TV, the TV is an insignia from BB... any thoughts?

Usually you get those lines when....
wait for it....
wait for it....
the video ground isn't hooked up.

Wow, what a helpful response, sorry to fatigue your precious fingers with all those return strokes...
Converter is the board from Nixs at jammaparts.net
Here is what it looks like now with the video ground connected... brightness will not adjust this on converter board or the tv

You can say it isn't a helpful response, but it's the simple answer to your question.

The other answer to your question is "YOU'RE NOT USING THE RIGHT MONITOR"

"My car was starting to act up, so I went ahead and put my lawnmower engine in it. Whyyyy wonnnttt it runnnn righhhhhttttt ???"
 
Wow, you are right, I suppose I should have known that, because I am a video genius, OR, I dont know shit about LCD TVs vs monitors and I come here for assistance to make sure my retardation doesnt spread to all of my games.
Im trying to do a solid for another guy, so I will tend to ignore said pretentious posts,
-Can anyone explain why this LCD is not the right type of monitor, or why it looks the way it does when the converter board is used? Refresh rate, VGA settings, I dunno, I know nothing about this type of stuff....
 
Look dude. You came here and said "Why is my screen dark when my video ground isn't hooked up" and I told you to hook the video ground up. Then you started acting like a bitch, and I clued you in that... as you look around.... most people don't put LCD's in arcade games because it often doesn't work.

I know you're pissed because you just wasted a shit load of money, but guess what? It's not my fault. I was trying to help you and you don't like the answer.
 
NO, I wasted no money, he wants to put this game in a childrens center, he has no med res monitors growing on trees, asked me to help him put his lcd in it, had a converter, hooked it up, looked funny, asked questions, you answered like a doosher, Im not butthurt about it, you look like an ass, and I still have the same problem, move along and Ill try to get this resolved for him.
 
Almost looks like the colors are inverted. Is the conversation board upscaling to VGA or XVGA or something? Can you try another LCD monitor to see if you get the same results?

Or maybe a CRT monitor thats capable of VGA (640x480) or SVGA (800x600) to see if you get the same results?

Also, does the conversion board have any gamma or contrast adjustments? Might be too high.
 
I think the ultimate problem is the guy trying to work on it is says things like 'doosher'.


And don't tell him to adjust it, he already said he tried that so now you're a doosher.

Just like if he says "I didn't hook up the ground' and you tell him that the screen looks like that when the ground isn't hooked up... you're a doosher.

LOL


"My monitor looks bad when the ground isn't hooked up."

"hook up the ground"

"You suck!@!@!! Fuck you!!! I want more answerz!!!"

-Just tried another lcd computer monitor, same results.
-Converter board has an onboard menu, have the resolution set to 640x480, the TV autoranges to that even if you change it. The native resolution on the game says this:
Video resolution: 496x384 in 65536 colors
Geometry: 180,000 polygons/sec, 540,000 vectors/sec
Video: Shading Flat Shading, Diffuse Reflection, Specula Reflection, 2 Layers of Background Scrolling, Alpha Channel
Display: 36" 16:9 widescreen CRT

Adjusted the brightness on the converter board with little effect. Colors are correct without the ground hooked up, with the ground on it is super bright with washed out colors on both monitors. Adjusted contrast, brightness, saturation on the converter, to no changes really. This converter is supposed to use it circuitry to auto range I read somewhere, manual is not helpful, at least not to me. Saw a few other threads using this in a paperboy, and it seemed to work fine, also med res monitor game. Ill continue to mess with it, any input appreciated from others who may have used one of these..
 
Got it! For future reference,
Get a good VGA cable, the one the guy gave me was brand new, I tried another one I had and bang, solves that. Now for adjustment purposes, now that I have it closer to correct, you can adjust the pots above the inputs, and it fine tunes in,

looks perfect now, and game will be defaced for lots of kids to enjoy, he will be a happy guy.

Just goes to show you, new doesnt always mean that its good or working.
 
correct or not that looks sweet.....thanks for sharing the solution. I'm currently trying to get a small LCD to work in a multi taito cab I got with no monitor.
 
Good job

Good job and thanks for posting the results even with these guys talking down to you, They talk down to me in most of my post too, I have reported them but the mods always seem to protect these guys. I'm glad you got it working. And despite most of these guys feeling lcds look better in most 90's plus games and the only way to go with a 60 n 1. I wonder if you even needed the converter board though, I think you could have just changed the connector to vga and plugged it into the tv, it works for most med res games.
