I posted this to the ARPA Info-graphics list several weeks ago and thought in light of the recent Monitors discussion this might prove useful to someone: In our projects and several others here at CMU we have the SONY 1270Q/1271Q series monitors. These are very high quality monitors with some great features and reasonable cost for the quality they give. They have the Super Fine Pitch Trinitron picture tubes. (0.25mm) Resolution RGB 600 lines, Colorpure Filter fine picture detail without color spill or color noise. auto frequency control switch to select the horizontal AFC time constant. LineA or B/VTR/RGB/CMPTR input select. Accepts PAL,SECAM,NTSC, and NTSC 4.43 color systems automatically! Under scan mode, [this is a very nice feature] There are optional 19" rack mounting attachments and slide rails. Audio in connections are also available. There is a speaker and volume control (not often found in monitors) The front panel and rear panel are very nicely laid out. The CMPTR connector allows microcomputer connections for digital or analog RGB signals. It also has a signal line for acceptance of the IBM PC monitor screen. A traditional 8pin VTR connector is also provided. (We just have a connector and hook in an NTSC signal) OUTPUTS: Video out, Audio Out, Ext Sync, RGB Out, RGB audio out, Loop through As far as size it's almost a cube, (13.5"x13.5"x15.5") [h/w/d] 31+ lbs. Within our project everyone has at least one of these monitors in their office. We pipe in a couple of broadcast TV signals, and several RGB signals from several frame buffers to each monitor. (There are many distribution amps for video signals throughout CS and Robotics to do this) The pitch and resolution of the monitors is very high. There are inputs and outputs for each signal to allow loop through with terminating switches built in. The newer 1271Q's (same price) automatically adjust for int/ext sych and have color temperature adjustments for photographing from the screen. They don't take up much space either, although you may have a small mass of cables coming into the monitor. It's a 13" diagonal screen. I have a small patch panel to the side of mine to make switching easy, to check out new cameras and change signal paths easily. We have also modified one of these to provide an NTSC to RGB conversion! They cost about $760. nivek Arpanet: nivek@cmu-ri-rover Bell: (412) 578-8830 USmail: Robotics Institute CMU Schenley Park Pgh, PA 15213
