That's over six times the resolution of the most frequently found graphics resolution of 640 x 480 (VGA) (which is also supported by this Panasonic projector). In addition, this Panasonic data projector support graphics resolutions of 720 x 480, 720 x 576, 832 x 624, 1280 x 720 (HD 720), 1280 x 800 (WXGA), 1366 х 768, 1400 x 1050 (SXGA+), 1440 x 900 (WXGA+) and 1600 x 1200 (UXGA) and 1680 x 1050 (WSXGA+).

4 Reasons Against

Does Not Support Full HD Projection

The PT-CW331 does not support Full HD projection, although this is within the context that most of the other 8000:1 contrast ratio data projectors that have been around for around the same time as the PT-CW331 also do not support Full HD projection.

There are a number of other projectors which also support Full HD projection that you might want to look at including the Viewsonic PRO8520HD[plb_1610101_price], or the Sony VPL-FHZ55[plb_1596654_price].

Chart Edit

High Running Costs

Based on average energy prices we estimate that the PT-CW331 will cost £154 over 1 year to run, which is in the most expensive 8% of all 13 projectors of a comparable age and type.

Quite Short Service Life of Lamp in Economic Mode

The average service life of lamp in economic mode of projectors that have been available for around the same time as the PT-CW331 is 4,400h. The PT-CW331 has a quite short service life of lamp in economic mode (only 4,000 hours) compared to most of the other data projectors of this age and type.

The Panasonic PT-CW331 has a pretty typical projector brightness (3,100 ANSI lumens) compared to most of the other projectors that have been around for a similar time to the PT-CW331.

Alternative 3,100 ANSI lumens brightness projectors currently available which you might want to look at include because of it's better review score, the Panasonic PTCW330U[plb_1925639_price].

If this data projector projector brightness is too dim for you then you might want to consider the IN3134a[pl_2544144_price] (4,200 ANSI lumens and higher rated), or the IN3136a[pl_2544145_price] (4,500 ANSI lumens and higher rated) both from Infocus.
