How do I resize the screen to fit my monitor?

I'm here to help you resize the screen, Msell.

We'll have to adjust the browser's zoom settings and the computer's display settings. It helps the software or page to fit your monitor.
 

Let me share with you the article to guide you with the adjustments: Unable to see the entire page in QuickBooks Online.

If there's something else that you need, feel free to let us know. We're just one comment away. Take care!

As of yesterday, the register in 3 of my Quickbooks 2019 accounts became too large (Long ways) to fit the screen.  I do not have online Quickbooks.  It fills the entire screen plus I am unable to see the last line on the register or see the "Record" to save an entry.  The register will not shrink down from the bottom or top.  I can, however, arrow it to be smaller on the left and right sides.  

I have a total of 7 Quickbook accounts.  Three of them are having this problem.  When I open these 3 account registers, it lists the last 25 checks.  When I open the other 4 (that fit the screen fine), they open up showing the last 19 checks.  They are all using the same font, so I think the problem is that the number of previous check is 25 instead of 19, which makes the register too long, so I can see the last check,  or the "record" button.

I hope you can understand the situation and help me.

I've got some troubleshooting steps we can perform to fit the register window in QuickBooks, Sue1093. 

We can change your default settings in QuickBooks Desktop to resolve a strangely sized Register window. Before adjusting any Windows settings, let's change first your display and view preferences in QuickBooks. Let me show you how: 

1. Close QuickBooks Desktop.
2. Open the Windows Start menu.
3. Type "QuickBooks" into the search. Then right-click the QuickBooks icon and select Open file location.
4. In the folder, right-click the QuickBooks.exe file and select Properties.
5. Go to the Compatibility tab.
6. Tap the Disable display scaling on the high DPI settings checkbox. You can also select Change high DPI settings and then Override high DPI scaling behavior.
7. Select Apply and then OK.

Then, open QuickBooks and access the account registers to see if there's a display issue. If the same thing happens, proceed to Step 2 in the Fix screen issues in QuickBooks Desktop article to troubleshoot the issue. If the problem persists, I'd suggest contacting our Technical Support Team. They'll pull up your account in a secure environment and investigate what's causing this issue.
