SBart, my situation was similar . . . my TV is mounted on a wall of rough irregularly-shaped stone, and like you I took some high-res photos of the area where the TV would be. Hooked my laptop up to the TV and set the TV as a second monitor, and then used photo retouching software to crop/resize/color correct it until a “full screen view” of the image on the TV was what I wanted. (And it was pretty cool . . . .)
Best I was ever able to accomplish with the iOS version of DumbThings was to get that image as a photo in Mono — which, as you, indicate, is not what I was after because of the mat/frame that it uses.
Using the kludge I alluded to on p.2 of the comments in this thread, I was able to trick the Android version of DumbThings into using my image as a background image. However, when DumbThings did so, it reduced the resolution and screwed up the color correction. I was able to correct that a bit via the on-screen controls — it’s now “just OK” (and I am using it), but it’s nowhere as good as the original image.
(I’d post a link to the step by step instructions on how to do the kludge (it’s pretty involved), but as mentioned earlier in the thread those were posted in a thread on the Samsung US boards. The Moderators / administrators there respond to people like me calling Samsung out for this kind of false advertising and their disingenuous responses to known flaws by banning us from the site, so unfortunately I can no longer get it for you. Bunch of despicable cowards, that lot.)
Ambient Mode remains a disappointment at best, a deliberate fraud at worst.
[...] Then...I tried to add photos from samsung account (which is the second option, the first is gallery) and ambient mode got "broken" again. Samsung support had to hard reset again to get the ambient mode to work again.
So....do not try to send your own photos to tv from samsung account!!! It will ruin your ambient mode and you need to call support to fix that! Since hard reset I have uploaded a dozen of own photos succesfully to tv and it works as promised!!!
Hi, not sure if this post can be of some help for those who has this issue. I'm from italian community and i had the same exact issue with the ambient not showing picture from the samsung cloud, and got broken. This happend until this morning, when, for pure fortuity, i wanted to try switching the TV language from Italian to English. After that, the ambient mode started to load pictures from the cloud. Every time i activate the ambient mode, the picture shown (in the mono mode) is picked up randomly.
I tried to switch back to Italian, and things got broken again. Then returned to English, and it's ok. For now i'll keep it this way.
