ViewSonic PJD7583w review
The build quality of ViewSonic projectors is impressive and the 3D-ready PJD7583w is no exception, with a compact, rugged plastic construction that feels tough enough to survive a classroom; weighing in at 3.5kg, it’s just about portable enough to heft around. It’s flexible, too, while its 0.5:1 throw ratio means you can get a 95in image when the projector is only 91cm away, and it can deliver images between 30 and 300in.
This projector is also versatile: using the network management software, you can project from up to four PCs at the same time. There’s a USB port that can be used for presentations stored on a flash drive, and this is compatible with various file formats including JPEG, GIF and TIFF. Note that in this mode file size is limited to 8,000 x 8,000 for JPEGs, and 1,280 x 800 for other file formats – as a result, we couldn’t display some of our larger files. Even so, it’s handy if you want to show a set of digital images without using a PC.
Video connectivity is disappointing. It would have been great to see an HDMI port, or even component video inputs, so you could plug in a laptop or Blu-ray player and make the most of the high resolution. Running costs are good: lamp life is 4,000 hours, or 6,000 hours in Eco mode, with replacements around £100.
The PJD7583w makes it easy to select signal sources on the remote control, and the quick auto search feature means the projector will automatically detect a device you plug in. If more than one is connected, the projector will cycle through the available input signals.
The 3,000 lumens rating resulted in images looking clear and sharp, even in a well-lit room. While the Epson produced more dynamic colours, the ViewSonic has the edge on contrast and clarity. The single 10W speaker won’t deliver hi-fi-quality audio, but it’s loud enough for the average classroom. The PJD7583w runs cool when running at full pelt, and switch-off is fast at around five seconds. This projector is ideal as both a table-top and ceiling-mount model, and many teachers will like its versatility.
