Title: (UPDATE) Would this be good for my retro consoles?
Post by: ulera on August 31, 2012, 09:15:59 pm
http://www.ebay.com/itm/SILICON-IMAGE-DVDO-iSCAN-PRO-PROGRESSIVE-SCAN-LINE-DOUBLER-480P-OUTPUT-/271040621562?pt=US_Audio_Cables_Adapters&hash=item3f1b47abfa

From what I understand... I could use this to turn my 240p consoles into 480p and connect it to my Vizios VGA port so they don't look so terrible in high definition. Am I right?

Yep, you'd essentially be line-doubling to produce 480P via RGB/Component output with that. The DVDO iScan units work pretty well from what I've read.

One last question... it says RGB output but that looks like a VGA port. Is it the same thing?

You'll need to buy a separate output cable. Have a look at the manual I linked.

Looks like I have a choice between VGA or VGA to component cables... of course... with only $40 left in my fun money budget now it comes down to deciding whether to go to the flea market tomorrow or not lol.

There's a choice of 3 cables: VGA-VGA, VGA-RGB, and VGA-Component. Make sure you get the right one.

My TV has RCA, VGA, Component, DVI and HDMI inputs so RGB isn't an option. :(
Title: Re: Would this be good for my retro consoles?

A VGA-VGA cable would be your best bet then.
Title: Re: Would this be good for my retro consoles?
Post by: ulera on August 31, 2012, 10:05:38 pm
Why's that? Since the resolution is 480p why would the type of input make a difference?
Title: Re: Would this be good for my retro consoles?

I believe VGA is naturally RGB so no color space conversion needs to take place in the scaler like it would if you converted it to component, so since your TV accepts VGA then it's a better (cleaner) signal from the unit. Someone will correct me if I'm off base.

So I actually went with this model (Saw it was ending in a half hour and bought on impulse): http://www.ebay.com/itm/290769404373?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

It has RGB BNC output though. Now my TV has neither RGB input or BNC input so I'm going to need to get either a BNC to VGA adapter or BNC to componant adapter. Anybody here have any opionions?

Post by: ericj on September 08, 2012, 04:03:39 pm
You'll also need something to convert RGB to YPrPb (component) if your TV doesn't accept RGB signals. A BNC to RCA cable isn't too expensive.
Title: Re: Would this be good for my retro consoles?
Post by: ulera on September 08, 2012, 04:39:31 pm
Rather then buying a converter... would it be cheaper and plausible just to use some bnc to rca adapters connected to one of those cheap rca to scart adapters off of ebay connected to a scart to vga adapter to my tv.

Correct me if i'm wrong but isn't that all the same kind of rgb?

EDIT: Actually this cable would be perfect! I just need to find one that isn't $25

Monoprice sells a cheaper BNC<->VGA cable, and cheap BNC<->RCA adaptors. It looks like you'd want the latter to connect composite or component signals to your line doubler inputs.

One big difference between different "kinds" of RGB is the sync signal: VGA has separate horizontal and vertical sync signals (so it's sometimes called RGBHV), but SCART usually uses composite video as sync.

So this arrived today and I tested it with my Gamecube and my SNES.

In both cases, it KIND OF worked on the gamecube startup screen but it was very fuzzy, as soon as the game started though the picture degenerated into white noise.

Tested the SNES with Pipe dream and the logo and credits displayed although they were also fuzzy and the screen rippled. Not to mention everything was too dark.

I actually managed to get a displayable picture with Mario Party through jiggling the cables and constant restart but it was VERY fuzzy and black and white.

So what do you think is the problem here? The DVP, the BNC to VGA cable or my TV? (Note, when nothing is hooked into the DVP it displays a plain blue screen just fine.)

How are you hooking them up to the video processor? I would assume RGB cables, except the US gamecube doesn't output RGB.
Title: Re: (UPDATE) Would this be good for my retro consoles?
Post by: ulera on September 20, 2012, 05:30:42 pm
the dvp accepts s-video and outputs rgb. I'm connecting it to my tv using a rgbhv bnc to vga adapter

Do you have anything else outputting s-video that you could test with? A DVD player maybe? (Don't buy something just to try it out though; this DVP thing may be busted; might not be worth sinking more money into it)

Have you used the VGA port on your TV before? Just want to rule out the TV.

For that matter, have you used the s-video with your Gamecube/SNES on other displays? Might as well rule out bad s-video cables too.

Do you have any other VGA displays you can try with?

You say it displays a blue screen just fine; could that be something your TV does if it gets no signal (common on older TVs I think), or can you tell that it's definitely the DVP?

Does the DVP have any menus, etc? (I see from the eBay photo that there's a picture button, what's it do?)

Do you have the H and V BNC cables the right way around? Maybe try swapping them? WARNING: don't try this if you're using a CRT monitor!

Does your TV say anything about the signal? What resolution it thinks it's getting, etc.

Forgive me if this sounds insulting, but do you have the BNC cables plugged all the way in? They're supposed to "lock" in place with a twist, if that makes sense.

Sorry, I'm taking stabs in the dark here. I don't know anything about the DVP, and it looks like Runco's website only lists their current products.

S-video cable works, TV works as I've used both before. Whenever I don't have anything plugged into the VGA port and try to use it though my TV usually will display a blank screen for 20 seconds then the power saving stuff shuts off the display so the DVP is sending through a signal of some kind, swapping the h/v doesn't produce a picture.

BNCs are locked into place.

picture button just changes what settings the value button adjust, so ruling all those out it's either the cable or something going wrong in the internal conversions, the resolution my TV says it's outputting is like 1024by768 or something close to that.

The final pic is the closest this device ever came to working.

only old 14-21" CRT TV is good for retro consoles

Seems like your TV is picking up the right signal, it just can't lock onto it properly. Not really sure what to suggest, does your TV have any useful advanced menu options? Maybe try altering the resolution of the VGA input of your TV, most TV's let you do this.
Title: Re: (UPDATE) Would this be good for my retro consoles?
Post by: ulera on September 21, 2012, 09:00:49 am
The tv automatically adjusts it's resolution to match the signal. :/
I have no control.

Bump. Gonna sell for parts if I can't fix this soon. Any other ideas?

If it still doesn't work when my rca to bnc adapter come in i'm shipping it.

Post Merge: September 26, 2012, 01:22:28 pm

Bnc adapters didn't work. Running the device through a vga to composite converter yielded a misalign and extreamly dark picture but somewhat viewable. And with that I give up. Any takers? $5 plus shipping.
