The Evolution of CRT TVs and Their Unique Advantages
Flat-panel displays have come a long way since they started to replace CRTs, but the old tube TVs still offer distinct advantages over modern flat panels. While many people assume that CRTs are outdated and inferior, there are specific models that remain highly sought after for their ability to deliver an exceptional experience with retro games and standard-definition content.
Not all CRT TVs are created equal. Just like today’s display technologies, different models had varying capabilities and features that set them apart. Among these, five types of CRT TVs stand out as rare but valuable finds for enthusiasts.
HD CRTs: The Flat-Screen Before Flat-Screens
If you think high-definition resolutions began with LCD or plasma TVs, you’re mistaken. CRT technology was capable of delivering high-resolution displays long before flat panels became mainstream. For example, CRT PC monitors could support resolutions like 1600×1200, which is close to the pixel count of 1080p. This means it’s entirely possible to have an HD CRT TV, and indeed, some models do exist.
Models such as the Sony WEGA XBR, Toshiba Cinema Series, and Panasonic Tau were designed to offer full HD resolution. Most of these used interlacing rather than progressive scan, but many also supported 720p. Since CRTs don’t have a fixed pixel grid, neither of these resolutions needed scaling, resulting in smooth visuals. Although 1080p progressive scan CRTs are rare, they can be found if you know where to look.
These TVs pair well with Blu-ray players or HD consoles like the PlayStation 3 or Xbox 360. However, later systems like the PlayStation 4 dropped analog outputs, requiring special converters or CRTs with HDMI inputs, which are uncommon.
Despite their benefits, HD CRTs often lack native support for SD consoles like the NES, SNES, or PlayStation 1. Many of these TVs use internal digital processors for resolution scaling and deinterlacing, which can add input lag when playing standard-definition content. For non-HD consoles, an SD CRT might still be the better choice.
EDTV CRTs: The Forgotten Sweet Spot
There’s a middle ground between SD and HD TVs known as Enhanced Definition TV (EDTV). These sets don’t offer more spatial resolution than standard SD TVs, but they do support progressive scan. Unlike traditional SD TVs that use interlacing, EDTVs provide a smoother image by displaying full frames per second.
Interlacing can cause issues with fast-moving images, leading to flicker and artifacts. EDTVs eliminate this by supporting 480p, which results in a stable, sharper image. To take advantage of this, you need a device that can output a progressive scan signal, such as a progressive scan DVD player or certain games on the PlayStation 2.
Not all TVs with component inputs are EDTVs. If you’re looking for one, check the model number to confirm it supports progressive scan at 480 or 576 lines. EDTVs are ideal for watching widescreen DVDs and enjoying a cleaner image from retro consoles.
Widescreen CRTs: Yes, They Exist—and They’re Glorious
While most CRT TVs have a 4:3 aspect ratio, there were a few widescreen models that allowed users to watch 16:9 content without black bars. Some of these were also HD CRTs, while others were widescreen EDTVs. Retro games on consoles like the PlayStation 2 and GameCube often featured widescreen modes that could take full advantage of these TVs.
Widescreen CRTs are particularly appealing for those who want to enjoy modern content without the limitations of older aspect ratios.
Pro Monitors and Broadcast CRTs: The Holy Grails
Professional CRT monitors, such as PVMs (Production Video Monitors) and BVMs (Broadcast Video Monitors), were designed for video editing and film production. These monitors are highly prized in the retro gaming community because they support direct RGB input, offering a clean and pure display for retro consoles like the SNES, Sega Genesis, and PlayStation.
While these monitors tend to be smaller than regular TVs, their compact size is often seen as a benefit. Not all PVMs are compatible with commercial hardware, so it’s important to research before purchasing. Some models may only work with proprietary RGB formats that aren’t useful for gaming consoles.
Even without a professional monitor, some CRT TVs can be modified to support RGB, providing similar results. However, careful consideration is necessary to ensure compatibility.
The Quest for CRT Greatness Continues
CRT manufacturing ended over a decade ago, with recycled CRTs becoming scarce by 2015. As a result, these displays are growing increasingly rare, and many will eventually stop working. This makes the current era a critical time for collectors and enthusiasts to seek out and preserve these unique pieces of technology.
For many, the search for a perfect CRT TV is an ongoing effort. Whether it’s a widescreen HD CRT hidden in someone’s garage or a rare EDTV, the opportunity to enjoy the distinct qualities of CRT technology is quickly disappearing. For now, the hunt continues.
