VIVIDSTORM-Laser projector 4k screen PRO 100 Inch Cinema Office/Home 8K/3D/UHD Motorized Floor Rising Screen Ambient Light rejecting screen pop-up screen Suitable for UST Laser projector, VMDSTUST100H

We LOVE how it looks in our space, and have to say, so far, the manufacturer has been very supportive in trying to get our issues solved. Basically, the automated screen requires calibration. A little plastic tool is provided but our screen has gotten stuck in the wrong position several times, makes an awful noise and came with a broken tension string on one side.We hope to get it to address so we can enjoy it fully, but it's been quite frustrating to try and calibrate it so it works properly.Update: first one was wonky - this company has great customer service. They were responsive, tried to help and then sent a new one when we couldn’t solve (really fast). The new one is fantastic and works perfectly!!

Coupled with my new Optoma 4K Laser Projector this combo provides, in my case, a 100” image that is every bit as good as my 65” LG OLED picture which was rated by reviewers as the best in 2018. Plus you only put up the screen when you watch TV. So very spouse friendly. The light rejection this screen provides is amazing so watching with lights on or during the day doesn’t wanna out the picture. We love it. Perfect combo for very immersive home theater experience! Highly recommended - so far. Do have long-term worries about support if/when motor that raises/lowers the screen fails.

If you're considering one of these screens, this is what I'd say: be aware that the lift mechanism makes use of what amounts to a pair of deadly, human-sized mousetraps.Pros: - The UST/ALR screen material is decent for the price - The floor rising capability is nice in principleCons: - Ours failed without warning in a DANGEROUS and violent way after a just year's worth of normal living-room operation - After disassembling it (so as to get rid of it) I found signs that the assembly process is low-precision, seemingly "trial and error" and these mistakes likely caused the dangerous failure.The way the screen works is like this: - The screen is on a motorized roller at the bottom, and attached to a flat metal bar that runs across the top - There are two articulated, spring-loaded arms behind the screen. These are attached to the bottom and the bar at the top so as to be always "pushing up" on the screen - When you raise the screen, the screen coming off the motorized roller "lets out" these springs as the arms "push up" the top of the screen. - When you lower the screen, the screen spooling back onto the motorized roller "reels in" these springs - At all times the arms keep "pushing up" so that the screen can remain nice and tensioned from the bottom to the top of the range of motion.Here's the problem: those spring loaded arms use POWERFUL springs. These arms are attached only to the bar across the top, and to the housing at the bottom. Ours was assembled with low precision and little care, and the attachment point at the top failed after a year's worth of normal use.When this happened, the spring arm was able to free itself from "pushing up" on the screen and, in a matter of a few miliseconds: - the spring force snapped a solid piece of metal that was part of the spring arm's joint halfway up - the bottom half of that arm, still spring-loaded, became free to swing outward to the side of the screen - that arm had the remains of the broken joint on it, a chunk of metal weighing several pounds - this club-like arm SWUNG OUT AND DOWN AND SLAMMED FORCEFULLY INTO A WALL -- luckily, not into a window, or personI wasstanding very close-by when this happened (in the middle of turning off the UST projector) and I want to make it clear: this was no joke. Imagine an adult person hitting the wall with a golf club about 80% as hard as they possibly could. That's the kind of forceful, weighted impact we are talking about.After this happened the screen was still half-up and half-down, and only one arm was blown -- meaning a second spring was still loaded up in there. I had to drag the screen outside to safely figure out a way to get it taken apart.When I did the above, I noticed many signs that the manufacturer's assembly was a low-precision / "trial and error" process. Likely this was a contributor to the failure. I've attached pictures to show what I mean.I feel fortunate that no people and nothing valuable was hit by the arm, and that I was able to safely unload the other spring.

Had this screen since March 2020 and have used the motorized up/down perhaps 50 times. I was a bit nervous from day 1 on first use when I would see metal shavings on the screen and then horizontal lines all the way across. The screen is good about those evening out and the metal shavings did lessen on future uses. I was overall happy, until very recently when on use I noticed 4 impressions on the screen (the pictures don't do them justice) that almost looked like they were going to poke through along with the grease like line at the bottom. The indents have some what gone away, but the grease line was not fully cleanable and now it is just ugly there. Bigger problem is I don't feel like I can safely use this product again, what happens next time I wish to collapse the screen and extend it for use? I contacted the company, but of course no response. This screen isn't cheap and while I knew it wouldn't last forever, I was hoping for more than 50 uses (rough guess).

We bought this screen to go with our Vava UST projector. Considering it had to come from China to the US, the shipping time was very reasonable. The screen is pretty amazing. It sits in front of a window and no light passes through. Even in a fully lighted room, the picture is great. With the lights off, it's amazing.I had to contact their tech support over a remote control question and they were prompt, helpful and extremely nice.Overall, it's been a great experience.

I have to say that tracking is product through custom shipping with DSL it's somewhat nerve-wracking, but when it was finally delivered it was very well packed and in great shape. It's almost literally plug it in and turn it on, with no setup.I haven't specifically tested the ambient light rejection, but I can see the screen has ambient light rejection technology in it. I am currently using it with a vava 4k laser UST projector and am very happy with the results. I showed the setup to some friends and they kept remarking on how crisp the image was. One thing that surprised me is that it wasn't nearly as loud as I thought it would be opening and closing.
