This projector is 1080p only. HDMI has supported 60Hz at this resolution since the first version. See: https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_standard_video

These two; https://www.digitec.ch/de/Comparison/8121409-2470890 have a maximum noise level of 28dB and are very bright.

Hello Kwikiel, I think you need to have the serial number of product and a proof of purchase (bill) and register your product here https://epson.promo-rewards.eu/C4GOAL0418/de-CH hope that helps. Cheers

The mounting screws are only on the underside. If you use a "conventional" mount, you have to turn the projector around. But there are other mounts for this - or you can build something yourself that is more like a shelf on which you place the projector. As for the second question about volume. I cannot confirm this. The projector has different operating modes (depending on the lamp power -> the fan has to work more or less), which are "tone-setting".

The choice of surround system is completely independent of the projector. The basic rule for sound systems is that the "complete systems" (e.g. from Samsung) that are available for approx. 500. CHF are all no good. And since, in contrast to the projector, the loudspeaker boxes last an extremely long time and are almost never technically "overhauled", you can keep them for 20 years or more without any problem. It is therefore worth investing a little more in the sound system and buying a decent amplifier (e.g. Denon AVR-X1400H; approx. 550.- CHF) plus 5 decent speakers (e.g. Canton; together approx. 1200.- CHF) and possibly a suitable subwoofer (approx. 500-800.- CHF).

Hello. The ratio between projection distance and image size is given by the ratio of the technical data sheet (1.32-2.15:1), i.e. for a 2m wide image the distance between the projector and the screen will be between 2.64m and 4.30m, for a 3m wide image, the distance will be between 3.96m and 6.45m.

Most projectors have a function that distorts the image so that the angle to the wall is correct. I don't see why the height should be a problem.

not to my knowledge, i have placed a switchable socket in front of all devices. this way the power consumption is zero ;-) there is often cheating with these specifications

Two matching cases are linked to the article in the accessories category. The following link will take you directly to the bags Epson EH-TW6700 (Full HD, 3000lm, 1.32 - 2.15:1, LCD, UHP) .

Hello, The TW6700 does not have a Bluetooth function for sound transmission. However, you can connect an appropriate Bluetooth module or the optional wireless adapter to the jack socket for sound transmission.

The requested demo product is a returned unit.

Hello. 3D glasses are not included and must be purchased separately if required. These would be the matching glasses Epson ELPGS03 3D glasses (shutter system)

Can be calculated here: https://support.epson-europe.com/TDC/ThrowDistanceCalculatorDE/ According to this calculation, at a distance of 7m the projector creates a picture of 146" - 237".
