    Here's a few options. (These are from Amazon US, so you may need to adjust for your location.)
    • Wii to HDMI Converter ($10) - upscales the 480p signal to 720p or 1080p, and has separate 3.5mm analog audio output. (Not sure how good the input lag or quality is, though.) Requires a passive HDMI to DVI-D adapter cable for your monitor.
    • Wii/PS3 to VGA cable ($24) - this only provides color conversion, not upscaling, and works for PS3 as well. Has 2x RCA audio connectors for audio. Note that you'll need to set the system to 480p prior to using this cable on the monitor; the monitor probably won't show 480i.

    You don't want to do this trust me. I tried it with a ps2 long ago. The two connectors rca/component/svideo OR rgb/dvdi/hdmi are NOT compatible, therefore you rely on a "converter box"'.... well let me tell you what this converter box will do, especially if it is cheap

    -really muck up your picture quality
    -induce delay into your controller button presses

    you must, buy a tv with component/rca input

    RGB/VGA and component are the same electrically, it's just different connectors

    if that is true then why do you need a converter

    ... Because the connectors are different?...

    It's worth noting that not all games support 480p. Many can probably be forced to 480p with a USB Loader though.

    See I tried this. With the converter box, like 10 yrs ago, with xenosaga for ps2, all colors were washed out, screen muddy, all grey and stretched out picture, input lag on good 20" HD monitor, it looked real bad. AFAIK component and rca are easily interchangeable, not so with component and rgb/vga

    Close -

    The 'RGB' signal that's normally provided over SCART connections for AV equipment is 15khz with a single sync source for both horizontal and vertical, where as VGA is usually above 31Khz with an individual sync for both axes.
    Now component video is a somewhat different beast in that it's the same signal with a differential color encoding scheme - but ideally the output *should* be identical to an RGB source (transcoding between the two is in principal a lossless operation).

    As for displaying 15Khz RGB on a VGA capable display - if the display is multisync then there won't be any issues, otherwise you will need to introduce some type of video (or exclusively refresh) processor into the chain.

    Isn't that equivalent to the argument: "I had a car that had terrible paint work & broke down a lot, so don't buy any car ever."

    The schematic for component to rgb I was looking for is offline, but going the other way is similar. Whether you consider this easy or not is subjective.

    http://www.sega-16.com/forum/showth...to-Component-(YUV-YPrBr)-schematic-and-layout

    Some VGA monitors will accept a 15khz & 31 khz video input on the VGA port. However if the OP's doesn't then a simple conversion cable is not going to be acceptable.

    well, at the time, i used rca cables to a vga converter...

    so you are saying component cables to a vga adapter would look good? has anyone tried this, is there picture degredation or input lag?

    after my converter box experience, i assumed the signals were too different to convert well

    The cool thing is that you can output rgb using the gamestop component cable on a crt pvm/bvm with yellow composite being the sync.

    Depends on the converter. I bought this cable a while back and I believe it uses a single-chip transcoder that merely converts from YPbPr to RGB without upscaling. The upscaling is what introduces lag, not transcoding. The downside is you won't be able to use 240p/480i inputs, since most VGA monitors don't support them.

    Component cables are YPbPr, not RGB. That having been said, most PVM/BVM monitors support both RGB and YPbPr; you just have to select the correct input type. If the monitor's set to RGB but you're using YPbPr, the image will be almost entirely black and green. If the monitor's set to YPbPr but you're using RGB, it will look almost entirely white and purple.

    Nope not true, I can output RGB on my PVM using the Gamestop component cables. The component cables can output either RGB or YPbPr. I use the yellow composite cable for sync. The same is true for scart cables, I can output either RGB or YPbPr using scart.

    I know its outputting RGB when using component cables, because I have set to RGB using the switcher on my PVM. Also the sharpness, color, and tint controls are deactivated when outputting RGB. Those options are only available when I output composite or s-video. Component has tint deactivated, but color and sharpness are adjustable. Only brightness, contrast and white balance are available to adjust using RGB. If I can't output RGB using component cables, then why am I outputting RGB?

    I have my PVM calibrated to a white point of D65 using a color analyzer meter, which is the industry standard for movies, for accurate grey scale and color reproduction. Simple switching to 6500k isn't enough for an accurate white balance, especially with old used PVM's/BVM'S where white balance has drifted over time. I also noticed when measuring gamma, RGB mode has a natural gamma 2.22 thats spot on, but in component mode gamma is a little off from 2.2. I have no idea if other PVM's/BVM'S are like this.

    are you sure your PVM/switch isn't auto-detecting signal source?
    A normal Wii component cable doesn't carry a yellow line.

    Gamestop component has a yellow line.

    If I just connect the red, green, blue cables my PVM starts going all wavy and out of sync when in RGB.
    When I connect the yellow cable to the sync input everything is just fine. I use the rca plug to bnc jack on my PVM. The PVM I have is the 1344Q.

    Scart cables can output RGB and YPbPr. If you have a ps3 you can check right now.
    Go into your video output settings, go to avi multi/scart, and it gives you the option to select Y Pb/Cb Pr/Cr and RGB.
    Component cables are able to output both signals too.

    so are we talking about general standards or are we talking about specific setup? There are all kinds of weird setup out there.
    Standard component outputs are not compatible with standard RGB inputs. General component cable are just 3 conductor pairs which can go into anything that accept RCA connectors, it is the job of the output and input devices to match each other. The Wii specifically have its own kind of output connectors.

    It depends on what you mean by standard.

    Official ps3 component cables has the contacts on the output connector to get RGB color signal through component. No modification needed.
    That would be standard cables since they are the official ones. Though since your missing sync you'll get a rolling picture. Sync is passed through a separate cable for RGB. You can get composite sync by soldering the composite cable to the component cable. Gamestop official cables already has composite on there so no soldering needed. You don't have to worry about sync on YPbPr, only needing 3 cables since sync is passed through the Green cable along with Luma signal.

    If they don't have the contact pins then no RGB through component. All playstation component cables, official ones, has RGB through component.
    Unless you call playstation cables a specific set up. So in a way you are right, if you don't consider Sony official cables general standard.

    Yes its true standard component cables output are not compatible with standard RGB inputs, because usually, consumer displays only has a scart input for RGB, so you'll need an adapter. The same with my PVM having no scart or rca inputs, only BNC inputs. So i'll need an adapter to get video on it from rca.
