How Does an Integrated in a Monitor 3D Vision IR Emitter Look Like

September 14th, 2012 · 2 Comments · GeForce 3D Vision


Have you ever wondered how does the new infrared IR emitter integrated into the latest 3D Vision -Ready 3D-capable monitors look like? Well, wonder no more as you can see it on the photo above. The 3D Vision IR emitter on the photo is the one found inside Acer’s HN274HB 3D-ready monitor, though it should be pretty much the same as found in other models. The IR emitter module is connected directly to the monitor’s driver board and the connection seems quite solid, though at the same time quite a few people have had issues with integrated IR emitters not working properly or not detected as being connected with the last generation of 3D Vision 2 monitors. If you get an error message that the IR emitter is not connected you may try to open the display and connect it yourself (if it has been physically disconnected), it is not be that hard. Be warned however that opening your monitor will void the warranty, so open the monitor yourself only if you know what you are doing and have no other alternative – when returning it for repair or for replacement is not an option. Have in mind that if the IR emitter is not being detected or working properly there could as well be a defect in the hardware itself, and this is actually the case most of the time.

    This advice is for my BenQ xl2420tx, but may work with other monitors. After the emitter stops working, due to power outage or the like, there is a way to toggle the internal connector that connects the emitter to the rest of the monitor’s circuitry.

    After your emitter stops working, you can try unplugging the monitor and plugging it back in. If that doesn’t work, you can try viewing the bios using on of the on monitor buttons (lowest one on my benq). It will show an option for rs232 (as in serial port connection) that will be set to off. Try turning it to on, and then toggle the power on the monitor a couple of times. That should fix the emitter not working. For whatever reason, sometimes the rs232 port is disabled, which makes the monitor unable to communicate with the emitter.

    I myself think te absence of a detection of the unit is an nvidia driver flaw as I have gone throug a few desktop transmitters that many times fail to get detected without pluggin in an out again
