The bulb broke 3 months after purchase (a good 150 hours of operation) during operation and is currently being "repaired" (warranty replacement of the bulb). Otherwise, I have been very satisfied with the price/performance so far. The thing does what it is supposed to do.

There is no standard picture mode with this projector, everything is set directly to user.

We have now included it at the following link: Optoma UHD51 (DLP, 4K, 1.21 - 1.59 :1, 2400lm)

Can you find it in the shop? Optoma UHZ65 (DLP, UHD, 1.39 - 2.22 :1, 3000lm) regarding delivery date you have to ask the customer service, no customer can help you there.

Wanted to ask the following but there was always a server error 500.... Does anyone have the same problem of not being able to focus the image properly everywhere? Primarily left or right sharp but both together only moderately "sharp" possible. This is even worse in the corners. I have the beamer upside down. At the bottom of the picture with lens shift approx. 2/3 downwards (from the beamer in upright position it would be towards the top) the bright icons/font even have a glow towards the outside. With min. lens shift (image towards the centre of the lens) this is better. With focus too, but then it is totally blurred on the other side. In addition, when I switch to "dynamic" mode, the picture or the lamp is as bright as Bright, for example, when I have vlc open maximised without video (black).

Depending on whether the manufacturer certifies the products as 4K, we draw boundaries. In this case, it is the case that the manufacturer indicates the device as 4K-certified and accordingly, we must also indicate it as such.
