I have an acer X1340WH. First I bought 2 pairs of very good American brand. The blacks were not quite black but I put it down to the video that cost me less than 400 euros. I then took two other pairs for friends and issue of having troubleshooting. And testing those, I was stuck by the color rendering. The black is really black and rendering, greatly surpassing the record movies. I am a happy buyer and I RECOMMENDED other pairs to let others troubleshooting.
Also I would like to acknowledge the professionalism of the seller contacted me to ensure compatibility. You need a 3D ready DLP video projector.
