Optical Lens Shift and Geometry Corrections

While having optical lens shift would be considered a common feature for certainly classes of projectors (e.g., mid to higher-end home theater models), it is not very common for this class of DLP business or education projectors.  The Pro8530HDL offers vertical lens shift, but of a limited range.  For example, with a 100 inch diagonal 16 x 9 screen the projector's lens shift adjustment allows the user to adjust the vertical offset between 9.3 inches and 18.7 inches.  This means that with the projector sitting level on a table the bottom of the 100 inch (diagonal) projected image must be a minimum of 9.3 inches and a maximum of 18.7 inches above the vertical position of the projector's lens.

The projector also has vertical and horizontal digital keystone adjustment. for when the projector must be tilted, but generally, as with all projectors, use of keystone adjustments should be avoided when possible due to the image degradation that it introduces.  Automatic vertical keystone correction is offered as well as manual vertical keystone correction adjustments.  There are also adjustments for corner geometry connection.

Flexible Connectivity

In addition of the projector's rear panel signal connectors, the Pro8530HDL supports connectivity via a  multipurpose port that Viewsonic calls "PortAll" connector (see photo below) that is hidden under a removable panel on the top of the projector.


The "PortAll" connector provides an additional HDMI input, and in this case, with MHL support.  MHL is essentially mobile HDMI.  MHL is relatively recent, so it may see a lot more capabilities down the road.  To be effective, since MHL supports video, audio, and command and control, a projector really should have its own sound system, which this projector does have.  Some phones and tablets, as well as all kinds of other smart devices are being designed with MHL.

An optional HDBaseT dongle is offered by Viewsonic that plugs into the "PortAll" connector to add support for this A/V network capability.

Another optional accessory for use with the "PortAll" is the ViewStick2 Wireless Presentation Dongle.  The ViewSonic ViewSync® ViewStick 2 is a powerful and compact wireless dongle that enables 1080p contents from mobile devices, PCs, and laptops to be wirelessly streamed to the projector. The broadcasting contents include multimedia, documents, browsers, and files on cloud storages. Built-in storage, it can play contents directly without computers. Compatible with diverse devices and wireless networks using WPA2 security.  This accessory could certainly be useful when the PRO8530HDL is going to be used for multimedia applications.

4 HDMI Inputs

Most projectors have one or two HDMI ports, but the PRO8530HDL has 3 rear panel HDMI ports plus one "hidden" multi-function port (the PortAll described above) which provides a 4th HDMI port with MHL support.

Centered Lens Layout

While many projectors have a physical layout with the lens offset toward either the right or left of the projector's centerline, the PRO8530HDL has the lens centered which may make a difference when installing the projector,  This could be especially important when replacing an older ceiling or wall mounted projector that also had the lens centered.

Network Support

The projector can be controlled and managed through a wired LAN network connection using just a connected PC and web browser.  In addition, support for Crestron e-Control/RoomView is supported.  This projector is also PJLink, SNMP V.1, AMX or Xpanel V1.10 compliant.

The Pro8530HDL supports wired networking thru the rear panel LAN port and two optional (extra cost) adapters are offered supporting wireless networking and HDBaseT.  Either of these optional adapters can be plugged into the projector's "PortAll" connector (described above).

The bottom line is this model is versatile in supporting the most common methods of control via a network and with the optional adapters can support audio/video networking via HDBaseT or wireless networking from with PCs and mobile devices.


DICOM Simuation Support

DICOM is a standard for viewing medical images such as CAT-scans, MRIs, X-rays, PET-scans etc.  A number of business/education projectors out there today do support DICOM Simulation, which means they are rated to be able to project such images at a quality level suitable for presentations and instructions.

The Pro8530HDL is suitable for medical education and training purposes with its DICOM Sim. preset color mode.
