The UHZ65 is a medium sized home theater projector. Measuring 19.6 inches wide, 13 deep, and 6 inches high, it’s finished in black with a silver trim ring around the lens. It probably won’t win any design awards for style, but it looks good. As seen in the 1st photo above, the air exhaust venting is on the left front corner, if you are facing the projector’s front.
The front feet are adjustable. The lens is slightly recessed, with manual focus accomplished by rotating the lens edge. There’s an IR sensor for the remote control on the front, to the right of the lens.
The other lens controls are on the top hidden behind a large door that is described in the section below.
The control panel is also located under that same large door on the top of the projector. More on that below.
All the inputs and the two rear facing four watt speakers are located on the back of the projector as seen in the 3rd photo above.
The projector’s rear connector panel is shown in the photo above. Starting from the left, there’s the power cord receptacle. For wired networking there’s an RJ45 connector for use with CAT5/6 cables. No projector is really complete without the traditional RS232 serial port for old school command and control.
Now we get to the inputs, starting with a pair of HDMI inputs. HDMI 1 is on the left, and is the older HDMI 1.4, while HDMI 2 supports HDMI 2.0, and the matching HDCP 2.2 copy projection that is required to play those 4K Blu-ray UHD movies.
There’s even a traditional VGA port for analog computer output. Of course, most things these days use HDMI, but should you have an old PC at home, you are covered.
After a space, there is a pair of stereo audio jacks one for input, one for output. A pair of USBs (one marked with power), a digital audio jack, and a 12 volt screen trigger.
Finally, there is a USB service port and an optical audio port.

The UHZ65 has a 1.6:1 zoom lens, as seen in the first photo above. The lens is fully manual for focus and zoom. Focus is adjusted via the outside ring at the front of the lens. The zoom and lens shift adjustments are accessed thru a pop open door on the top of the projector, as seen in the second photo above. The third photo shows the zoom adjustment toward the top (toward the front of the projector) and optical lens shift adjustment via the knob just back from the zoom adjustment. The lens produced good focus over the width of the screen. However, there was somewhat above average light fall-off, for a home theater class projector, toward the corners of the image.
