Screen Mounting Advice for Dropdown Screen

I just bought an Elite 84" dropdown (m84uwh) screen and need to mount it to the wall.

The instructions are a joke, it literally tells me nothing.

Here are the entire contents of the instructions for wall mounting:
-----------------------------------------------------------------------------------------
Mark the area from the screen mount end cap hole to the wall. Then mount the screen onto the wall (Fig 1).
-----------------------------------------------------------------------------------------

The only other instructions are for ceiling mounting. When I read this, I almost laughed.

Anyhow, it has some bigger bolt like screws which I obviously cannot use, but it also has 2 smaller screws with sheetrock anchors.

The screen weighs about 30 pounds. Do you think it is safe to use the sheetrock anchors without drilling into a stud? My only other option I can think of is to get a 2x4 and drill that in the studs and mount it to that. I live in an apartment, so I don't want to overdo it. I am not sure how much weight those sheetrock anchors can take, but 30 pounds sounds borderline. 10-15 pounds no problem.

Any advice?

Any ideas where I can find a pre-finished piece of oak that is already painted/finished in black and is in the size I need?

Home Depot? hmmm....

Actually, at Home depot they have specially made very large sheetrock anchors that are made for heavy paintings, they are rated over 50 pounds each. They can hold 100+ pounds if you run a thin metal wire between 3 and mount the projector screen on the 2 sides and then secure the middle.

The screen only weighs like 20-25 pounds. Still haven't mounted it yet, but this is what I'm going to do. Someone told me they hang paintings like that all the time, even paintings over 50-80 pounds. You just have to use multiple special anchors with some thin wire support for extra caution.

I think high rated anchors work fine for mounting a screen, but just be careful when you pull it down and let it back up, try to hold the top part of the screen in place so it doesn't move.

I guess overall I'd say it's fine to use picture anchors if you don't move the screen up and down a lot. I never wind my screen back up anyhow.

I know this thread is old, but just wanted to update it.
The screen mounted fine with (2) drywall corkscrew anchors, I show the anchors I used in my photo link at the bottom of this post. These things hold 50+ lbs each, there is no way a 25 pound screen is going to fall mounted to a spec of 100 pounds. Even pulling the screen down has no effect on the screws coming out, and I did not even attach the (2) screws together with a wire, they are purely in drywall without studs and they are not connected by a thin wire either. and this thing is super stable.

I had a very awkward shaped living room, but I pulled it off!

Here is the final setup:

The cork screw inserts are specifically anti-stud inserts. They hold 50 pounds each, and professional decorators use them to hang 50 pound paintings, and up to 100 pound paintings with 4 of them. Hardly a risk since the screen weighs 20 pounds.
Now if I were to yank the screen down without holding it or lived in an earthquake prone area, I can see a possible issue, but I'd never do it.
