@Trancemission just to be clear — the three other corners are perfect. The edges other than this corner are also perfectly straight. So this is NOT a keystone issue where two opposite sides are not parallel.

I’ve noticed this ever since setting up my Halo a few months ago, but I just never got to post about it. Specifically the upper right of the projected image slopes downwards, almost as if that part of it is occluded by something in the lens housing.

On a projected 100” image, I would estimate that the missing part of the image is about two inches below where the actual top edge should be.

Has anyone experienced this? I’m thinking I need to get this unit swapped out for another.

(How do I post a picture of this? Does this forum not allow for images to be uploaded directly? Seriously? I have to have the image hosted elsewhere first?)

Just to make sure — the Halo has auto vertical but manual horizontal keystone adjustment, right? If so, I tested this feature by moving the unit off to the right side (about 30 degrees from center). It tried to auto adjust things, but it obviously doesn’t do the horizontal keystone. So I thought I could adjust it manually and while I figured out how to do so, I could not get the projected image to look even on both dimensions.

What is the natural limit to how far to the left or right it can be and still produce an even/straight image? I am testing this with a 100” projector screen.

Setting to 100% brightness when using battery power does not achieve the same results as if the unit is plugged in. The image looks a lot more washed out. I think there is a natural limit to how much brighter the image can be with the brightness adjustment if there is a hard cap on how many lumens can be output on battery power. Clearly when the unit is plugged in the full 800 lumens are used. On battery power it is definitely lower. It’s just too bad that there isn’t an option to not have this behavior/feature be user-adjustable. (Obviously if this existed users should be aware that they could burn through the available battery power quickly)

I guess after reading around that someone has mentioned the HDR issue which was confirmed to be an “optimization” issue that the Xgimi team needed to work on. What there really should be is a way to use SDR. Can anyone please confirm that Halo actually supports HDR content?

So I received my Halo today and it’s been great. Setup was a breeze and everything felt snappy. There are a few minor quibbles, with perhaps the most serious being the very dark movies/shows across the board. No matter the show or movie, the presented video was always dark. I’ve heard/seen on other forums that many other devices (not limited to smart projectors) such as smart TVs often times have difficulty with interpreting HDR content. This is possibly caused by the Disney+ app itself. However, what I am surprised at is HDR is not one of the available features on the Halo, so shouldn’t it basically be unaffected by this problem? Of course there is some guessing here, so hence I am wondering what you guys are experiencing.

I can certainly get the picture brighter by using the custom image mode. But as you know, jacking up the brightness causes dark scenes to appear washed out.

Speaking of which, is there a way to keep the projector at the same BRIGHTNESS when solely on battery power? I find that even using BRIGHT mode while on battery power is almost useless.
