The aperture grill blocks less light than a shadow mask, which translates to a brighter and more colorful picture. In general, a monitor with an aperture grill will be superior to one with a shadow mask. Sony was the first to introduce aperture grill technology under the Trinitron brand name, but Sony wasn’t the only company that sold CRT monitors with an aperture grill. An aperture grill uses an array of wires instead. A shadow mask does the job with a metal mask of evenly spaced holes. aperture grill: Which is better?Ī shadow mask or aperture grill is a filter a CRT computer monitor uses to make sure electrons end up where they should be. Late-model CRT monitors will be enjoyable at 800 x 600 or 1024 x 768 no matter the dot pitch listed on their spec sheet. This occurs when a CRT monitor’s dot pitch isn’t up to the task.ĭot pitch is less important if you only care to use a CRT at lower resolutions. A monitor with a lackluster dot pitch might support a high resolution but appear blurrier at a high resolution than a low resolution. Make dot pitch a priority if you care about sharpness at resolutions beyond 1600 x 1200. Lower is better, but you likely won’t find a monitor with a dot pitch below. I recommend monitors with a horizontal dot pitch around. All of these were designed with lower resolutions in mind, so the content I’m viewing is usually at a resolution of 1024 x 768 or lower.ĭot pitch is measured in millimeters. I use my CRT monitor to run Windows 95/98 in a virtual machine, play late-90s PC games, and emulate console games. The importance of resolution depends on your use. A resolution of 2048 x 1536 is the highest you’re likely to see. A monitor with a high maximum resolution will also support lower resolutions, and often a higher refresh rate. ![]() In general, the best resolution is the highest you can find. This 19-inch CRT computer monitor lists a maximum resolution of 1600 x 1200 at 85Hz but supports 1024 x 768 at 130Hz and 640 x 480 at 160Hz. Take the Hitachi SuperScan 751 as an example. CRT monitors were sometimes marketed with a “recommended” resolution that served as a guideline, but CRTs computer monitors support a range of input resolutions and refresh rates. CRT monitors are an analog technology and don’t have a native resolution. Resolution works differently on a CRT computer monitor than on a modern LCD.
