Link Your Atari Computer to an LCD Screen (30-60 minutes). Composite to S-Video Comparison

Task: Link Your Atari Computer to an LCD Screen

Recommended: LCD display screen, connectors


I enjoy my Sakata SC-100 monitor that I utilize with my 8-bit devices. We nevertheless have actually the one that is same used right back within the time with my Atari 800. Just as much as I favor this monitor i am aware it won’t final forever. There may come a time whenever i want to find an alternate. We have started preparing for the eventuality through getting the thing I need certainly to connect my Atari computer systems to a monitor that is modern television. There are lots of different choices to explore in this area. We shall concentrate here using one among these and save the others for future posts.

First a little bit of back ground about Atari 8-bit computer video clip. Every one of the Atari 8-bit computer systems have monitor port that outputs a composite movie signal. This is certainly a single-channel analog video clip sign that is attached to a monitor or television via a yellowish connector that is frequently discovered as an element of an RCA connector which also includes red and white sound connectors for stereo noise. The solitary channel of movie is called composite given that it creates a linear mix of the luminance (luma) that holds the brightness regarding the movie combined with chrominance (chroma) that carries along with. This really is a breeze and enables you to link any Atari computer that is 8-bit the composite out to a television or monitor using the composite (yellow) in. A number of monitors and TVs through the 1990s and early 2000s have actually composite in and tend to be still relatively simple to locate.

Even though composite sign is straightforward you will get definitely better quality video clip by continuing to keep the luma and chroma signals split and feeding the two-channel sign to a connector that is s-video. These connectors for your Atari are readily available as i will show below in the instructions. To look at difference between quality, we have actually included below screenshots of composite for a monitor that is crtmy Sakata SC-100), composite for an LCD monitor, and S-Video for an LCD monitor. Note the remarkably higher quality of this S-Video image. They were all three taken underneath the exact same illumination conditions during the exact same time. The LCD monitor is a Dell 2001FP monitor that is 20-inch ended up being remarkably popular within the very early 2000s. The video clip ports with this monitor are shown below.

Composite to S-Video Comparison

S-Video is obviously the approach to take. Regrettably, just the Atari 800, 65XE, and 130XE provide both the luma and chroma signals needed by S-Video. This might be issue since many Atari 8-bit enthusiasts utilize an 800XL that just includes the luma sign. The chroma ability can there be it absolutely was just never ever attached to the monitor slot into the 600XL, 800XL, and 1200XL. You will find guidelines online for just how to result in the connection to enable S-Video. We haven’t tried this yet but want to do a post that is future this. Listed here is an Atari Age thread with this.

Dell 2001FP Video Ports

The issue that is final sound. Many LCD monitors don’t have actually sound ability. This implies you will need to link the red and RCA that is white with a speakers. I’d a time that is really hard little speakers for the desktop that accepted RCA noise input. Luckily, there clearly was a Y connector that converts the RCA noise to a 3.5 mm audio connector found of many speakers. Details below into the directions.


Buy a Dell 2001FP LCD monitor or comparable. These can be readily entirely on eBay for approximately $50 to $100. You may have the ability to see them locally for less costly since there are many still around.

buy a composite to S-Video connector. They are often available on e-bay. I purchased mine from 8-Bit Classics. Expect you’ll spend about ten dollars to $25 for those.

Buy an RCA audio to 3.5 mm sound converter. Usually the one i purchased i discovered on Amazon for approximately $10.


I have discovered getting Atari video onto modern monitors and TVs to be one of the most confusing subjects. It is partly as the resources on Atari Age as well as other sources are inconsistent and sometimes assume your reader has more information about the technical part of movie than they most likely do. The things I described above is fairly simple and S-Video rocks ! for those who have an 800 or XE system. Getting these systems that are old HDMI is an account for the next time.
