I found a review on 3D glasses for the sainsonic 144hz vs Optoma ZD201 120hz , acer and a no brand name ( 30g ?),.. here is the link; http://3d.echeva.com/2013/03/17/%c2%bfmerecen-las-pena-las-gafas-3d-chinas-de-144-hz/2/
, although it is in SPANISH , there is a few images that show how much better contrast the optomas have compared to the sainsonics, the images show a close up on a space boot that almost disappears with the sainsonics which not only dim the picture but it also affects 3D a great deal,. .from the reviewers own words "a difference from night and day" , you can se more images to compare if click on " » Pág. Sig ." (next page) ,.. The review mentions the red flash on the the w1070 which is absent with the optomas,.../ he also tested them on the optoma HD25, which in this case had an awful green flash that made the contrast and 3D even worst., I agree that this sainsonics are ok for ooccasional guests but even then i'd probably let my guests use the better glasses.
(The reviewer used a SBS RIP 1080i @ 50Hz signal for the optoma and the acer glasses 120hz..) why ?, i dunno, i would think that the 120hz optomas would also do 1080p on a 144hz projector but i really don't know enough on this.
The optoma or the newer BenQ 3D 144hz glasses which should do even better, are just way too expensive specially when you need 5 or more pairs! ,.
The prices that this major companies (including Epson) put on their 3D glasses are very UNFAIR for the consumer with a tight budget looking for a decent home theater.
Anyone with their hands on a a good pair of 3D 144hz glasses that don't break the bank , please share link
