SMV 300 SERIES: upgrading the 280 series... and rounding it out.
The 28” videowall monitors of the new SELECO SMV 300 series are versatile, robust and reliable video displays.

They are characterised by a rugged metal case, which is easily stackable. The new generation Permachrome Shadow Mask CRT guarantees excellent performance in terms of purity and contrast, also improving convergence and brightness. It allows the monitor to be used world-wide without the typical purity problems due to the earth's magnetic field.
Designed for the videowall application, due to the stylish cabinet, the SELECO SMV 300 monitors can also be used as a stand-alone video displays.They are easy to move being provided with carrying handles and easy to maintain as well. The SIM2 videowall monitors assure bright and sharp pictures with excellent colour balance due to the CRTs tinted phosphor and by using a CTI to increase colour resolution and a COMB filter to reduce cross colour and cross luminance. The videowall monitors of the SELECO SMV 300 series can be connected to PAL or NTSC video sources with automatic selection and size control. The videowall monitor is available in 3 models: the SMV 300 N, SMV 300 RGB, SMV 300 DELTA. The SELECO SMV 300 N features a wide range of inputs (composite video 1 via BNC, video 2 via SCART, analog or TTL RGB signal via DB9-sub or SCART), with video loop-through. The monitor features the video priority capability: if more signals are connected at the same time to the different input connectors (video 1 - RGB - video 2), the input displayed will be the one with higher priority. The SELECO SMV 300 DELTA has the same performances as the N model but is housed in a wedge-shaped metal case, to obtain round videowalls. The SELECO SMV 300 RGB is a simplified and cheaper monitor specific for videowall; it accepts only an analog RGB input signal via DB9 connector. For uses in TV studios, all the videowall monitors include 2 colour temperatures (3,200°K and 6,500°K) switchable by internal switches, with adjustments for both black and white levels.
