    Not sure if I understand the question. Are you asking if it's possible to buy the cable in that link? It's for sale, so I'd say yes. If you're asking if that cable would work with that monitor, I'm not sure, but probably not.

    I can't find much information about it, but it looks like a standard computer monitor to me. What makes you think it's an "RGB" monitor? Technically, nearly all CRT computer monitors accept RGB (specifically RGBHV), but to accept the kind of RGB output that comes from SCART you need a converter or scaler. I'm not aware of any computer monitors with BNC inputs. That doesn't mean they don't exist, but they're certainly not common. If I'm telling you something you already know, I apologize.

    I should have clarified when asking my question. I was looking to see if anyone had actually had experience with attempting this with a computer monitor. The Monitor actually has BNC hookups on the back which are RGB but I am just not sure if that is the same type that's needed for an SCART hookup to work. The cable is not all to expensive and it might be worth a shot but I also might be able to get my hands on a couple of Sony PVR's from a local hospital which might work out. I'll try and take a picture of the monitor and see if it helps out at all. Thank you for the reply!

    Ok there is totally one more hookup there than what I remember.

    Hm... it might work. It looks like it has inputs for horizontal and vertical sync, but it also says "H/C," so maybe the "C" stands for composite sync. If that's the case, it might work. It also depends on whether the monitor accepts 15khz.

    If not, I can tell you that cable will definitely work with a Sony PVM.

    According to this page: http://www.monitorworld.com/Monitors/nokia/multigraph445xpro.html the horizontal and vertical sync are 30-121 Khz / 50-150 Hz respectively. So it wouldn't work with a SCART cable, which usually carries a ~15khz signal. It looks like a pretty good computer monitor. It'd be really good for playing Dreamcast games with the VGA cable.

    I recently discovered that Dreamcast over VGA on a CRT looks way better than on an LCD. Unfortunately, all I have is a little 13 inch PC monitor. It looks great, but it's very small.

    That seems like an amazing solution! Are there any cons to this approach?

    Also what about all of the SCART to HDMI adapters and SCART to Component? I ask because in storage I have a Sony Wega with HDMI and component. http://www.amazon.com/Sony-KV-30HS420-Trinitron-HD-Ready-Widescreen/dp/B0002F7I9O

    Cheap scalers like that usually don't produce a very good image. If you're looking to play older consoles over RGB on a computer monitor or an LCD, XRGB is probably your best option.

    XRGB is definately the best bet, but not cheap. I'm happy with the above solution for the price.

    Even better when used with the SLG3000 scanline generator if that's your thing.

    Scaler linked to is great for the money (much cheaper on eBay). Sync striker is overpriced tho, you can make your own for about $2

    I have one of those and while it does work with many of my consoles ,except for my SNES, it doesnt actually upscale. Only allows for Scart to Y-U-V. If you plan on sending it to an lcd, you will get nicer colors but there will be quality loss due to stretching unless you use a scaler. I have never tried one out on an RGB monitor though. I would bet the quality is MUCH better. Right now I use one in conjunction with the scaler mentioned by Shakey_Jake33 ,but like Bad_Ad84 said, just buy it off of ebay and make a sync strike yourself. Much cheaper that way. Here is tutorial by mmmonkey if you are interested:

    That offers direct conversion from RGB SCART to component. No scaling, aspect ratio correction, or any other widgets. The most simple and economical approach available. Particularly for CRT users who already know their TV accepts the console's video mode.

    It outputs the original resolution and refresh rate supplied to it. So it's not going to do things like make PAL systems work on a regular American SDTV.

    I ended up ordering the RGB to Component converter since I am hooking it up to my CRT. I am also going to order the cables for my Genesis and Saturn and give those a go as well. I will post an update with links to parts and results when they are all in. I wonder if it would be a good idea to start a sticky with information and opinions on things like the XRGB-3 and the different converters. Thanks for the answers so far in this thread I really appreciate it.

    If you want to learn more about XRGB and other kinds of scalers, this is a good place to look: http://shmups.system11.org/viewforum.php?f=6&sid=cfc391b06b580637ad438006d91f4216

    Fudoh (a member on that forum) is really knowledgeable about this subject, and he's always open to questions. He also has a website about scalers: http://retrogaming.hazard-city.de/

    There's also a wiki devoted to it: http://junkerhq.net/xrgb/index.php/XRGB-3

    Oh yeah, there's also a successor to the XRGB-3 coming out at some point, called the XRGB-mini Flame Meister (or Frame Meister) G2.
