Reddit mentions of SLLEA RCA Composite AV S-Video to VGA Converter Box for DVD DVR VCR Monitor

Definitely. Keep in mind that the highest quality output that is available on a PlayStation 2 is Component RGB. So if you see any devices claiming to convert the PlayStation 2 signal to HDMI, they're actually using the Component RGB output of the PlayStation 2.

Also, since 99% of PlayStation 2 games are 480i or lower, you'll find that the S-Video signal is indistinguishable from Component RGB.

I recommend one of these, which inputs to your monitor's VGA port, and can be used with any old console or other device that outputs Composite or S-Video signals:

My initial post was a bit disorganized since I was on my phone. If you're still looking for options, I've summarized them for you, and made notes as to visual quality and price.

Option 1: Composite to HDMI or Composite to VGA adapter. These low price adapters can vary greatly in quality and lag, but will still get the job done. HDMI is probably more useful in the long run, but the VGA one might have less lag added, and has the benefit of also supporting S-Video input. If you look for others, make sure you are getting analog in and HDMI out, and not the other way around! This route means less things to buy, but I do not recommend staying with composite. Visual quality is garbage.

Option 2: S-Video to HDMI or S-Video to VGA Both of these products also accept composite input, but I really suggest getting yourself this Nintendo S-Video cable. It's inexpensive, and the difference between Composite and S-Video on the Gamecube is phenomenal. If you prefer to stick to the Gamecube and don't want to spend too much, this is definitely the way to go.

Option 3: Gamecube component cables and component to HDMI. I don't recommend this route. The Gamecube component cables are ridiculously rare and overpriced. They also only work on early model Gamecubes with this port on the back. Yes, they give an awesome improvement on visual quality, it's just not worth it for the money. Especially when you have...

Option 4: Get an Early Wii: The original Wii systems have gamecube backwards compatibility. Additionally, Wii Component cables are inexpensive, as are the Wii to HDMI adapters. These Wii to HDMI adapters should in theory be better than normal component to HDMI converters, since they were designed specifically for the Wii. If you already have an older Wii, or you don't mind investing in one, I absolutely recommend this route above all other options. You will unquestionably get the best quality for your money.

Option 5: Metroid Prime Trilogy. If you have a Wii or WiiU, you can look into the Metroid Prime Trilogy for either system. The WiiU's version is available on the Nintendo eShop, and outputs HDMI natively. For the Wii, you'd still have to do Option 4 above, so it might not be worth it unless the trilogy interests you.


Future Options to make note of:

HD Retrovision is looking to create a low cost analog to HDMI converter that is optimized for retro systems. When it comes out, it will very likely be the best budget converter for retro systems.

Modders are creating a way to replicate the expensive Gamecube component cables. This project also includes the ability to output digital 480p via HDMI directly from the system...no conversion needed. The latter will likely be the best output the Gamecube will ever be able to offer. The project is open source, but several known modding sites like badassconsoles.com will be selling kits or modding consoles themselves.

There, I think I hit everything. Hopefully that helps!

yes I used a composite to vga convertor, pretty much converted any signal to the required vga resolution so what the monitor supports is not an issue (like this]

I used to use it to connect an old composite tv tuner / media box to a CRT monitor and then a TFT, pretty much looked like a normal CRT TV to me :) THough I don't know the effects for retro-gaming

Here you go on amazon. Decent reviews

Something like this should work, but expect it to look like crap. You'd be better of spending the same money on a small CRT TV from craigslist/goodwill/letgo/whatever.

I could be wrong...but I'm pretty sure you can't split the cable destination with RCA like you're trying to do. Meaning I think you have to plug all three (red, white, and yellow) RCAs into the monitor.

Going off what I said above, If you want the sound to come out of your Bose. Then you would have to use the monitor as a pass through...only problem is, it might not have extra RCA ports for, "audio out" on that old of a monitor.

Ignore what I originally said as that probably isn't the problem.

As others have suggested a new cable might do the trick. You've already said you're getting one. If that doesn't work. Maybe get something similar to this RCA to VGA adapter as there is probably something wrong with the monitor.
