UHP lamp, lens, connectivity
The most important difference between the new TW7 and TW9 models with 4K enhancement and the LS10000 that we previously tested is the fact that the LS10000 uses reflective instead of transparant LCD panels. While the LS10000 uses lasers, the cheaper models use a traditional UHP lamp. A disadvantage of this is that the lamp is not immediately at its brightest level and correct colour temperature after turning it on. Furthermore, the lifespan of UHP lamps is limited, although the model in the TW9300W is supposed to last 3500 to 5000 hours according to Epson, depending on the mode that the device is used in.
An advtange of the LS10000 that can be found on the TW9300W is that this model is equipped with a motorized lens. This allows it to electronically set the zoom, focus and lens position and create multiple presets. This is especially an advantage for people that work with a "constant-height" screen, where cinemascope images are shown without black bars above and below the image. Because of the motorized lens and the possibility to create presets you can easily switch between 16:9 and 2.4:1 image ratios. The quality of the system seems fine as well. After multiple changes between presets the lens positions were correct, without any deviations.
In any case, the lens system of the TW9300 is of excellent quality. The projector retains its sharpness in the edges compared with the middle of the image, and thanks to the zoom level of 2.1x and horizontal and vertical lens shift the projector is easy to place.
If you want to place the projector in a hushbox there is more good news, because it is not necessary to have airflow from the front to back over the projector. The intake for cold light happens next to the lamp at the front left, while warm air is pushed out at the front right.
All connectors are at the back of the projector, behind a removable cover. If you do not use a wired connection, you can leave the cover on- this makes the back look very clean. The connectivity consists of two HDMI-inputs of which only one is suited for signals with HDCP 2.2 encoding and with that for signals from modern devices such as ultra hd blu-ray players. Also present are a VGA-connector, a trigger-output, RS-232C connector, LAN connector and two USB (service) connectors.
