It could be that you've zoomed in your browser, denis.

We can zoom it out to make the page smaller. Press Ctrl key on your keyboard and the minus (-) repeatedly. Also, let's make sure to maximize the browser so we can view the full QuickBooks Online page. Just click on the Square button beside the X at the right top.

Let's also check your computer's display settings. QuickBooks Online requires the screen resolution is set to 1024x768 or higher and the Dots-per-inch (DPI) set to "Normal" or "100%". You can follow these steps to check it:

For Windows:

1. Right-click any blank spot on the desktop. Select the Screen Resolution.
2. Check the screen resolution if it's set to 1024x768 or higher.
3. Select Make text and other items larger or smaller and make sure that the DPI is set to Smaller - 100%.

For Mac OS:

1. Click on Apple menu and select System Preferences.
2. Select Displays.

Any of these steps will help you to view the full QuickBooks Online page. Post again if you need more help.
