BenQ 5J.J8C14.001 Long Standard-Throw Lens Guide: SH960+ and TH963 Compatibility

Genuine BenQ Lens 5J.J8C14.001 Long is a factory-supplied optical accessory for BenQ business projectors. It is a standard-throw lens (Standard Throw) with a throw ratio of 1.93:1 - 2.90:1. The official model compatibility list covers 2 projector models. Before installation, simply verify the projector model and panel size; there is no need to make do with an adapter ring. The value of a factory-supplied lens lies not in the extra figures in the specification sheet, but in the fact that it is calibrated at the factory to the optical path and lens mount of that model series: once installed, the image circle, edge illumination, and focusing travel are all at their design values, so there is no need to compensate for image quality with keystone correction.

I. Lens Specifications

Brand	BenQ (BenQ)
Lens Model	5J.J8C14.001 Long
Throw Ratio	1.93:1 - 2.90:1
Product Type	Standard throw (Standard Throw)
Compatible Projector Models	2 models
Warranty	12 months; damage not caused by the user is eligible for after-sales service, based on the date shown on the shipping documents

The above specifications are subject to the original manufacturer's specifications. For mechanical dimensions, flange distance, and mount type not shown in the specification table, please verify them with us using the projector model. Ordering directly based on a similar model carries the risk that the lens will not fit.

II. Calculating Installation Distance from Throw Ratio

The throw ratio is the ratio of the installation distance to the image width. This factory-supplied lens is a zoom lens (1.93:1 - 2.90:1). A given image size corresponds to a range of distances, and the lens can focus anywhere within that range during installation.

Image Size	Image Width	Required Installation Distance
100 inches	2.15 m	Approx. 4.15 – 6.23 m
120 inches	2.58 m	Approx. 4.98 – 7.48 m
150 inches	3.22 m	Approx. 6.22 – 9.35 m
200 inches	4.30 m	Approx. 8.30 – 12.47 m

These figures represent the clear distances from the front face of the lens to the screen and do not include space behind the projector for cooling and cable connections. They are calculated for a 16:10 image; actual distances should be confirmed by on-site measurement and the manufacturer's manual.

Image quality differs at the two ends of the zoom range: toward the close end, the image is brighter and the edges are slightly softer; toward the far end, the edges are sharper and brightness is slightly lower. When the venue allows, it is recommended to position the lens in the middle of the range. After installation, first find the sharpest setting on the focus ring, then fine-tune the lens shift.

III. Compatible Models (2 Models)

The following table is taken from the official model compatibility list. Brightness and resolution are populated from the model database; where data cannot be obtained, an em dash (—) is entered, with no assumptions made.

Model	Brightness	Resolution
SH960+	5500 lumens	1920x1080
TH963	6000 lumens	1920x1080

To determine whether a model outside the list can be used, please send us photos of the projector nameplate and the existing lens for verification. Platforms of the same generation often share the same lens mount, but the risk of ordering based solely on a similar model designation is not worth taking.

Throw Ratios by Model Series

The nominal throw ratio differs when the same 5J.J8C14.001 Long lens is used with the series listed below. Select the value based on the series of the actual projector.

Model Series	Throw Ratio
—	1.93:1 - 2.90:1

IV. Three Checks Before Replacement

• Confirm the projector chip and resolution. The original lens is designed for a specific panel size. If the panel specification differs, the image circle cannot cover the full image, resulting in vignetting or loss of illumination at the edges after installation.
• Calculate the installation distance first. This lens has a nominal throw ratio of 1.93:1 - 2.90:1. Use the table in Section II to calculate the distance for your venue. A fixed-focus lens offers no adjustment margin, and a zoom lens should also leave 10–20 cm of margin at both ends.
• Verify the mount and locking mechanism. The original lens is calibrated to the lens mount used on that projector series. After installation, you must hear the lens lock securely into place. A skewed image or soft edges are usually caused by incomplete locking, not by a problem with the lens itself.

If you are unsure, take one photo of the projector nameplate and one of the nameplate on the existing lens, and send them to us. Verification against the actual hardware is the most reliable approach.
