8 Reasons Against

Does Not Support WiFi Connectivity

The PJD2121 does not support WiFi connectivity, although it is worth noting that most of the other similar spec projectors that have been around for around the same time as the PJD2121 also do not support WiFi connectivity.

We compared this projector to all the other projectors with a WiFi connectivity and we think the XJ-A147 (£906.00), or the XJ-M156 (£950.12) both from Casio is also worth considering.
