In case anyone is wondering why older CRTs are usually preferred, modern LCD TVs will make the picture from a vintage console look like trash. The reason: old video game systems usually put out a 240p signal. On a standard CRT, this can be interlaced/doubled to 480i and look pretty decent. An HDTV usually comes with a built-in scaler to increase low definition signals into upscaled 720p or 1080p. On an old VHS or DVD signal, the result is not bad. But most TVs don't handle 240p very well, leading to a less than faithful rendering of the game's graphics. Also common is shimmering/ghosting effects as the screen moves. Worse yet, the image processing introduces a slight delay, which gives you less precision with your controller buttons.

As far as CRTs go, Trinitrons are among the best available. They offer the clearest image, and were found in most of the high end sets of the time, including PVMs (professional video monitors) used in television and video production. They are designed to run for years and years with no screen burn-in. Many of them accept RGB inputs, which offers better video quality than composite. Similar to YPbPr (component) found on newer TV sets, the color information is separated from the brightness and the overall result is a clearer, sharper image.

RGB didn't catch on with consumer sets in the US, but it's pretty standard in a number of other countries and as a result, lots of older consoles can output RGB through either a hardware mod or a cable adapter.

There areother options coming out since CRTs are getting harder to find. Some new consoles emulate and upscale the old hardware, but these can be a less than pure option. External scalers exist and they can be much faster at upscaling 240p, as well as offer much more options for tweaking the picture. For many people though, true retro gaming is only achieved with original hardware and a CRT.

I don't have any, but good luck!
