A projection distance of approx. 3.5 metres is generally possible for this projector, but is at the lower end of the recommended range. At a distance of 3 metres, the image width is around 1.8 metres, at 3.75 to 4.15 metres a 2.5 metre wide screen can be fully illuminated. The projection ratio is between 1.5 and 1.66, which means that more distance is required for larger image widths. 3.5 metres is therefore sufficient for an image slightly smaller than 2.5 metres wide, but for maximum image size the distance should be slightly greater.

To determine the smallest image size that you can produce with the projector at a projection distance of 6 metres, you must take into account the projection ratio and the minimum projection size. The projector has a projection ratio of 1.50 to 1.66:1 and can produce images with a minimum size of around 0.84 metres. At a distance of 6 metres, you can therefore project an image size of around 0.84 metres or larger.
To calculate the exact image size, you can use the following formula: Image size = projection distance / projection ratio. With a projection ratio of 1.66:1, a distance of 6 metres results in an image size of around 3.61 metres. As this is larger than the minimum size, you can adjust the image size by adjusting the zoom or the distance.

The Optoma UHD38x projector does not have Bluetooth for sound. Instead, it offers a USB-A port to power an HDMI dongle such as Google Chromecast or similar devices, and there is also an integrated speaker for easy audio output without the need for external speakers.

Yes, it has 3 holes at the bottom for a projector mount. Such a mount is available, for example, from Optoma itself.
