Acrobat Reader DC window on external monitor is too big

I am using Adobe Acrobat Pro DC, Version 2022.001.20142

From the main menu, click View > Display Size and then click the desired size.

I have had this 'zoomed in' view for some time and had not been able to figure out how to resolve it. With some prior update, the client view  updated to "Large" display size. Selecting "Standard" as the display size has brought my client view back to what I would consider normal view. Hope this helps.

Ok, so I read through all of the suggested fixes here and found that a combination of them all with a slight added twist helped me.

Here's what I did:

1. File > Preferences > General - Scale for screen resolution > select "Never". Click ok. Close Acrobat.
2. Right click on the Acrobat Icon on your Desktop > Properties > Compatibility
3. Check Override high DPI scaling behavior
4. Click on drop down underneath that check box and select System (Enhanced).

This completely fixed the display issue being discussed in this thread for me.

Hi There,

This response may frustrate you all a little because I can't exactly recall the steps I went through to fix the problem re scaling of adobe on a second monitor - but I can assure you I have. In simple terms I experimented, basically using the change display options, and specifically by cutting out my primary monitor altogether so it only had the option to display on the second monitor. I did restart the adobe program, and found that on the second monitor displayed correctly. Obviously, I then wanted to use the primary monitor (my laptop) and then switched it back on, I went through a variety or random alternative (this is the bit I cant exactly recall). The adobe kept reverting back, however on one of the random monitor display setting changed (nothing fancy just around the one or two monitors, extend, replicate, etc., I noticed a message pop up (or appear somewhere on the display window) which said I had to sign out for before changes could take affect, so I did,(it gave me the option to do so as opposed to having to user log out - whether that's anything significant). Anyway now I am back in everything is sweet!! adobe properly scaled. I am tempted to piss around tryng to find the same exacting steps as I can see there are thousands of people with the same problem, but equally I am slightly scared I wont be able to redo the puzzle. My hope is that someone with more skill might put two and two together and figure out what I did to make it work. From a lay perspective it was reassuring to see the rescaling once I was only on the second monitor as that reassured me it would do so, probably why I tried (in my own way) to trick adobe / the computer to thinking it was still supposed to display it correctly even after switching the original monitor back on...

Hope this helps in some way.

I found the fix...

I use a 4K laptop Display scaled 150% and an external monitor at 1080P 100%

Go to C:\ProgramData\Microsoft\Windows\Start Menu\Programs

Right-Click Adobe Reader DC

Click Compatibility

Check the box next to "Override high DPI scaling behaviour. Select the dropdown and pick System (Enhanced) for Scaling performed by.

This should help! It worked for me.

Oh this is for Windows 10 BTW

When using the external monitor you can't even scroll down to the OK button to confirm your changes!  Tried all the suggested options - shrinks the heck out of everything with the PC display but the external is still a balloon - I'll likely shift our company to a different supplier, as we just rolled out new PCs to everyone with this issue.

Since different solutions seem to work for some and not for others, thought I’d post what (mostly) worked for me.  First, if you’re on a laptop & connected to a high-res monitor & having this problem, I’d suggest disconnecting from monitor & just using the laptop screen, so you can actually see everything.  Based on previous suggestions in this forum, in the Reader I went to Edit / Preferences / General, then by “Scale for screen resolution” I selected “No Scaling”.   I had tried that multiple times before, but when I restarted the reader the setting always switched back to “Auto-Detect.”  I finally figured out why – there’s an “OK” button at the bottom of the Preference box, and if you don’t click it, settings aren’t saved.  That’s pretty intuitive, but on my high-res monitor and with Adobe in big pre-school font mode before I made this change, the OK button just wasn’t visible.  No way to see it.  It only became visible when I switched to my laptop monitor.

(BTW… other option if you can’t see the OK button is to hit ENTER after making the change to No Scaling. That locks in the change, as well.)

Once I was able to click on the OK button, then things look good on my high-res monitor.  Some of the fonts in my menus are a little messed up now, and when I use the reader on my laptop everything is tiny… but it’s progress.

I found something that works for me.  I am running Windows 10 on a Surface Book with 2 external monitors connected to the Surface Dock.  Following along with some of the suggestions in the thread, I stumbled across this:

Right-click on Acrobat Reader DC icon.

Choose Properties

Select Compatibility tab

Check the box for "Override high DPI scaling behavior.  Scaling performed by:"

In the drop-down box, choose "System (Enhanced)"

Reopen Acrobat Reader DC

This works across all 3 screens for me with normal toolbar font sizes.  Good luck!

Is there still no answer to this?  I found this thread and expected by now there would either be a solution provided or some sort of update to the software to fix the problem.  I don't have this issue with any other program or app.

Same problem.  Dell XPS 15 laptop (3840 x 2160); Dell FHD monitor (1920 x 1080);  Acrobat Pro DC (v 2015.023.20070).
