I'm impressed with all the functionality and colors of my Head-Up display (2020 GLS580), but even on the lowest brightness setting I can still see the rectangular border behind the images/text. It is white in color but the gradient behind it is not solid. It looks smudged almost, I've attached a similar photo to what I see (but the background box is at least solid in this photo), mine looks like smudged glass (white is some spots but not visible in others). I tried taking a photo but the camera cannot pick up what I actually see. I have a 2019 CLS450 and it doesn't have this issue ... thoughts on how (if) I can get rid of it? I did wipe the glass down, still there.
Just curious if this imperfections shows up in the day, night, or both?
Both, but definitely more visable at night. If it's pitch black, it's really not visable, but under street lights it becomes more prominent, so I think it has something to do with light hitting the glass of the HUD.
Tried to snap a pic last night. This is what mine looks like on highest brightness level. There are areas in which you can see some light leakage of some sort that can be described as smudges. They are less visible when you're driving in a darker situation (areas with less light pollution).

Yes, mine is similar to the top right corner of your image, but it's much more prominent. Same scenario, if it's nighttime and I'm in a well lit area, it seems to show up.

Finally got a photo that shows what I actually see. Check out the top left in particular, it kind of looks like when a screen protector on a phone isn't pressed down all the way and creates a bubble, this is what I see.
So does anyone ever see anything other than a faint rectangle on their HUD? I'm assuming what I see (a faint rectangle but with "blemishes") is not normal?
Having a HUD issue myself with my three week old 2024 GLE53 with about 1200 miles on it. It happened just last night when I went out to the store. Ride out, no problem. Started it up to come home, and the graphics were messed up. I turned the car off and restarted...same. Turned off the HUD and back on again...same. It is most obvious with the off road view. I pulled over, turned off the head lights, and took some pics:

Hard to tell from the photo, do you mean that the images/text is not sharp? That's all I can see, on the plus side it looks like your "lighted rectangle" is all one hue/shade, so good to know that's what mine should look like.
Yah, it reminded me of when a monitor was about to die. I went out this morning...and it's fine. Just what I needed, something that will come and go. At least I have pics for when I bring it in for something else...
But yes, the kind of ghost image of the full screen is uniform. If I was seeing what you were seeing, I'd make them fix it.
I had this problem for a week or so. I thought maybe I inadvertently changed a brightness setting that caused the image to go to max brightness or something. Then it went away. It’s been a month or so and it hasn’t come back. I’m not aware of any OTA updates happening during that time but am unsure how to check the date of the last update.
Sorry for the delay in my update, dealer replaced the HUD and I no longer see any of the weird smudge-like white light all over the HUD display. The only issue is that my steering wheel is off center towards the left and the HUD display doesn't appear to be straight (leans down to the right). I wonder if my tech was still hungover from a holiday gathering.
Looks like I'll be back at the dealership to get both addressed in the new year. I'm happy my HUD looks much clearer at night without all that smudged light.

Two things ...
Did they tell you what the issue was with the HUD that caused the "white smudges" so I can tell my dealer what to look for?
Also, there is a hidden HUD menu that can be accessed rather easily (I'm sure you can find it online) that will allow you to change the "tilt" of the HUD so it will no longer lead down to the right. It only takes a few minutes to fix, easier than going to dealer.

No they didn't give me any info, particularly because it was a rush. I needed the car back for the holidays and so they plan to continue some other warranty work in the new year, my work order is still open so I didn't get the summary of work with my SA due to the circumstances. I'll make sure to ask though and keep you posted!
Thanks for letting me know about the hidden menu. Whew! Scared they would have to open up my dash again. I've already had it opened up for a faulty actuator; no issues with post rattles so maybe the techs are used to doing that work.

Is this part of the MBUX Dealer Mode or is there another hidden menu for the HUD? I couldn't find anything about this.
Are you just talking about the normal adjustment setting?
My HUD is the same as yours and the other who have chimed in. So that leads me to believe this is "just the way it is" and not an issue per se. And as far as I know there is not any way to adjust the opacity further. It doesn't really bother me but I agree it is kinda dumb since I have a 2019 CLS with HUD that doesn't have this issue. Going from that car to the GLS I feel like there are a few things that Mercedes has regressed with. The HUD Is a big one. For me at least.
I just googled it and couldn't find it either, I'll keep looking. It's a very simple menu to access just by holding down a few buttons or something similar and it lets you tilt the HUD along with a few other tweaks for how it is displayed. It's for the techs to get it right if they have to install a new one. It's not very useful, except for the above mentioned situation where the HUD is not level.

I found this but I'm traveling and can't see if we have a similar hidden functionality:
