The TouchSystems TE 1990R-D touchscreen monitor uses older resistive touchscreen technology, which means you have to press the screen for it to register your touch. The TE1990R-D has a SXGA resolution and 5:4 aspect ratio instead of 4:3 or 16:9. The screen has a lower contrast ratio than many of the other monitors we reviewed, and it isn’t as bright as other screens. It lacks built-in speakers. Overall, the technology this touchscreen uses is a little outdated.
The TouchSystems TE1990R-D monitor has a five-wire resistive touchscreen, which is older technology. It works when you press the screen with your finger or a stylus to connect the two layers on the screen together. Resistive screens are dust and splash proof; however, sharp objects can damage the screen and after a while, it will wear out.
This touchscreen monitor’s resolution is only 1280 x 1024, which is much lower than that of monitors from other companies. However, it’s also a smaller screen size, so this lower resolution is expected. The pixel pitch, or distance between the pixels, is standard for this size of screen and screen resolution. Additionally, the contrast ratio is a low 800:1 and the brightness is 200 candela per square meter. With the low contrast ratio and brightness, the display on the TouchSystems monitor is mediocre.
This touchscreen is a multi-touch device, which means you can use more than one finger or stylus on the screen at a time and register a response. Additionally, it has a 5ms response time, which is standard among the touchscreen monitors we reviewed. Unfortunately, this monitor isn’t as sensitive when you touch it as some of the other monitors that we reviewed are. Still, it’s sensitive enough that you won’t be repeatedly pressing on the screen to have it acknowledge your touch.
The connectivity options are limited with this touchscreen computer monitor. It has a VGA video output, but that’s it. It doesn’t have built-in speakers either.
The TouchSystems TE1990R-D rests in a stand that moves only up and down, not side to side. You can remove it from the stand and mount it on a wall if you want. It has a VESA mount on the back, which is standard.
This device comes with a three-year warranty.
The TouchSystems TE1990R-D has a smaller screen size and, as expected, a lower resolution than most of the other monitors we reviewed. It has a quick response time, though. The space between the pixels is a little higher than average for the monitors we reviewed. Although this is a suitable touchscreen monitor, the technology is a little archaic.
