If your display or processor supports a 240p input, but not RGB, you can convert your RGB signal to be compatible.


RGB to Component Video (YPbPr)

There are a few scenarios where converting RGB to component would be the right choice for your particular setup, such as using a consumer grade CRT (that doesn't accept RGB), or certain flat-screen displays.  A company called HD Retrovision designed specific cables for this use, but there are also a few generic converters available.  I tested both a CSY-2100 SCART to Y-U-V converter and a clone system (the clones look similar to the one in the upper left picture, but have the screws on the sides, not front.  Both worked very similar, however I had to tweak the tuning POT's on the clone system before it looked right.  Here's the POT's I tweaked, but YouTube user Billkwando also has a good video about it:

As an FYI, if you're using a 240p console on a basic, consumer-grade CRT, you won't see a big difference between RGB (or component) and S-Video...and it's certainly not as drastic a difference as seen on high-end displays.  If both your CRT and console support S-Video, that might be a cheaper solution.


Component (YPbPr) to VGA (RGBHV) & SCART (RGBs)

The Behar Bros have recently released the Garo, a component to SCART / VGA box.  This box ads no lag, as it doesn't scale the video and only converts the signal.  It offers some great features, like dual outputs, scanlines, SCART output and both RGBs / RGBHV outputs via the DSUB (VGA) port.  I found that it performed as good or better then all the other high-end component converters that used to sell for much more money!

The only issue I've heard people complain about is the Garo's scanlines aren't as pronounced as the scanlines from their other boxes, such as the SLR or Toro.  I actually took screen captures of both the Garo's scanline output, then ran the Garo through the Toro to compare the image.  Click on the picture to download a zip file of all the original screen captures (they're not watermarked, so please don't steal them ;p), but this picture sums it up pretty well - It's not a huge difference, but the Toro's scanlines are noticeably darker:

RGB to VGA (no scaling)

Some VGA monitors can accept a 320x240 signal, just not at 15Khz (or as RGBs).  Basically, the main differences between RGB and VGA is sync (RGBs vs RGBHV) and the refresh rate of the signal;  RGB refreshes at 15Khz and VGA usually refreshes at 31Khz or higher.  I haven't run into many solutions where this is the best option, however I wanted to list it.  Keep in mind that when you display 240p at a 31KHz refresh rate, the scanlines will look thinner then the original RGB signal looks on an RGB monitor or CRT TV.  In my opinion, this changes the whole look of the game and doesn't look good at all.  Said differently:  You can't make a VGA CRT look like a RGB Monitor by using a converter.

Decent RGB to VGA converters (that do nothing other than make the signal compatible, not “upscale”) are usually around $100. Keep in mind, these converters are not compatible with light gun games and the SegaScope 3D glasses for the Master System, since both were designed for 15Khz CRT.


VGA to HDMI (no scaling)

VGA to HDMI converters that offer no scaling are very affordable and don't add any lag.  These will only work if the source signal is 480p VGA and up, but are a great choice if you simply want to display 480p VGA on a TV that only has HDMI inputs.  Check the links to the right to purchase -->



This is handy when trying to use newer consoles on older monitors.  I tested this one and can confirm it's lag-free:



If you own a widescreen BVM with an SDi input, this is a must-have, as it's a lag-free device that can send your 720p HDMI signal digitally into your BVM:


Composite / S-Video to RGB

These converters do NOT improve image quailty at all!  That being said, they're great if you'd like to run all of your consoles through one RGB switch and one console isn't RGB modded.  A good, cheap one to look for is the Extron CD 400.


RGB to VGA (scaled to 480p)

Basic 240p RGB to 480p VGA scalers are available that do a good job.  In my opinion, if you need to use a VGA monitor, this is a much better solution then the above option.  If you need to scale bigger then 480p, or to a digital signal, it's better to use an upscaler, which is discussed in the next section: upscalers.



Please head to the Display RGB page for more info on how to get an RGB signal on your display. If you're here as part of the RGB Guide, please either move onto the next section: upscalers, or move along to getting your SCART RGB cable into your display.
