Here's why retro games look better on old CRT TVs

Your favorite games did look better when you were a kid, but it's not just nostalgia talking.

Igor Bonifacic for Engadget If you've ever tried to use your favorite childhood game console with a new TV or monitor, you were likely disappointed by what you saw. This isn't an issue when playing a version ported to modern systems, but is immediately obvious on the original hardware. While it's easy to blame nostalgia, the reason your favorite retro games don't look the way they do in your memory is more complicated.

The short answer is those games weren't meant to viewed on modern flat-panel displays. Games from the '80s, '90s and early 2000s were instead designed for the dominant display technology of their time: the humble cathode ray tube (CRT). It's an example of how technology and its shifts can shape an art form.

The mismatch you find when you revisit a favorite game is the result of playing it outside of the context you originally experienced it in.

Igor Bonifacic for Engadget When most of us think of CRT TVs and monitors, we tend to remember their disadvantages relative to modern flat panels. They were big, noisy and, most of all, heavy. Yet for all their faults, they represented an amazing bit of technology.

Inside every bulky CRT display is a sealed vacuum tube with one or more electron guns pointed at a phosphorescent screen. CRT TVs and monitors don't display individual pixels like their modern counterparts. Instead, they draw many horizontal "scanlines" each time their electron guns fire and ignite the phosphors at the front of the screen. Those lines are drawn from left to right, top to bottom, for every frame the display renders. Yet to the human eye, that process appears instantaneous.

This is quite different from how LCD and OLED screens work. They instead use a technique called sample-and-hold, meaning they display a full frame and hold it until they refresh. Due to this technical difference, CRTs offered far greater motion clarity than their LCD counterparts for many decades. It was only recently, with the introduction of high refresh rate displays, that LCD and OLED screens have come to match CRTs on that front. This is apparent when you revisit a game like The Legend of Zelda: Ocarina of Time. Its frame rate was low (20FPS) and inconsistent when you were a kid, but it was less noticeable because of how CRTs handled motion.

Motion is only one part of why retro games don't look right on modern TVs; resolution is the second major factor. CRT displays don't have "native" resolutions like their LCD and OLED counterparts. They can render many different resolutions without the smearing that happens when you try run a flat-panel screen at a resolution lower than its native one. The console gaming industry standardized around two resolutions prior to the PlayStation 3 and Xbox 360 era: 240p and 480i.

Today, 240p and 480i are defined as "standard definition" resolutions to differentiate them from the "high definition" and "ultra-high definition" resolutions that came after. The majority of CRT TVs ever produced were standard definition sets. Some high definitions sets were made, but by the start of the HD era, LCD screens had begun to overtake CRTs in popularity.

Yet another nice example of a developer keeping a midrange, composite-only, consumer CRT nearby to check how the game's visuals would look for the end user.

The number in each resolution is straightforward: 240p involved a CRT TV drawing 240 horizontal lines, while 480i saw it draw 480 lines. The letter that follows each resolution is more complicated. The "i" in 480i is short for "interlaced." When displaying an interlaced signal, a display completes two alternating passes to draw an image. It will first draw all the odd-numbered lines before doing the same for all the even-numbered lines. This sounds like a convoluted way to render an image, but at a time when technology was limited, interlacing allowed broadcasters to save on bandwidth. One byproduct of interlacing was producing the flicker CRTs are known for.

Igor Bonifacic for Engadget Now we have enough of a base to understand why retro games look the way they do on modern TVs. One major issue is that recent LCD and OLED TVs don't offer great analog connections. If you're lucky, your TV might have composite ports. But even if that's the case, composite cables introduce a lot of noise to the signal from your console.

Another roadblock is that modern screens aren't designed to display interlaced content. They use software to convert 480i content to 480p. That process, known as "deinterlacing," introduces input lag, which makes games feel less responsive. What's more, many moderns TVs will detect 240p content as 480i, which they will then once again try to deinterlace. In that case, the process produces visual artifacts like motion blur. This all happens before your TV attempts to upscale a 480p image to 1080p or 4K. Unless you own a dedicated scaler like the RetroTink 4K , blowing a 240p image up to 4K will not look good.

FFT is actually THE game responsible for this blog. When I got an HDTV in 2012, I hooked up my PS2, but when I saw FFT's dithering for the first time I thought my console was broken!

Then you have the fact that retro games' art was designed for display on CRTs. Over decades, video game artists developed and perfected techniques to make pixel art (and later 2D textures) look more lifelike. Dithering was one of those techniques. This involved artists...
