Changes

'''CRT''' (or '''cathode ray tube''') TVs are the old kinds of TVs that older consoles were designed to output to. They typically accepted signals with a 15.7kHz scan rate under NTSC or PAL standards. They are usually preferred for gaming because of its better motion, response times, and lower input lag compared to LCD TVs. CRT TVs have scanlines which help reduce the pixelation of older games.

They come in several forms:

*Most CRT HDTVs have either DVI or HDMI ports which can accept as low as 31kHz (480p at 60Hz) from a PC. They do not support 120Hz to force 240p resolutions while doing this.

Sony's PVM/BVM series and NEC's XM/XP series are considered god-tier. If you cannot find those specific models, look for presentation monitors, professional monitors, or broadcast monitors from any brand. If you search for "video monitor" on craigslist, you may have luck finding one. Sony [[wikipedia:Trinitron|Trinitrons]] are pretty easy to find, and they're on the high-end of consumer-grade CRTs. Sharp, Toshiba, and Phillips higher-end CRTs are pretty close in quality, so don't be afraid to pick one of those up. Make sure to test it before you buy and also check the back to see what ports it has. If you're in North America, coax and composite (red, white, and yellow ports) are the most common, but you'll get the best picture quality running your system through component ports (red, green, and blue video ports with red and white ports for audio). If a component is not available, look for [[wikipedia:S-video|S-video]] instead. It will look slightly worse than component, but since it is on a CRT, the picture will still look good.

You could also look for a 15KHz-compatible PC monitor (see below) or an arcade monitor, although you may have to adapt the input to work with it.

'''CRT monitors''' are CRT displays that are intended to be used from a PC, typically being driven by an RGBHV signal with a 31kHz or higher scan rate through a 15-pin VGA cable.

In GNU/Linux or *BSD, you would use gtf and xrandr to use custom resolutions. [https://wiki.archlinux.org/index.php/Xrandr#Adding_undetected_resolutions See here].

Please add to this list if you have a specific model CRT monitor that you recommend for using with emulation.

*'''[http://www.cnet.com/products/monitor-dell-e771p-17-16-vis-grey-crt-monitor/specs/ Dell E771p]''' - Very common CRT monitor. Able to boost color level intensity, allowing 240p with black frame insertion or 480p with inserted scanlines to have vibrant colors despite 50% brightness. Capable of up to 1400x1050 @60Hz with custom resolutions, but disallows 1440x1080 for some reason despite being able to display other 1080p resolutions at 60Hz.

All LCD monitors have a native resolution which all output must scale to, unlike CRTs.
