Need help for buying a Projector

Any of the BenQ series starting with the w1040 up to the HT2050a, DLP just is better at 3D. Some of the older Optoma models have a VESA port to use RF glasses that some prefer over the more common DLP link. Now your other issue watching from a PC can be challenging. Up to date video drivers have eliminated 3d support. Use older drivers or possibly some hacks to get around this. 3D formats of PC files vary drastically as there are many types. Half side by side/OU are the easiest to play but also the lowest PQ. The best format is ISO full rips requiring a player that can support them (rare) and hardware of at least HDMI 1.4. A BR player is an inexpensive simple solution that just works every time.
