Disable Hardware Graphics Acceleration in Office 2019?

Yes, you can disable hardware graphics acceleration in Microsoft Office 2019, and doing so often fixes display glitches, blurry text, or high CPU usage. The setting is per-application: you turn it off separately in Word, Excel, PowerPoint, and Outlook. This article explains exactly where to find the toggle, why it exists, and when you should (or shouldn’t) turn it off.

What Hardware Graphics Acceleration Does

Hardware graphics acceleration (also called GPU acceleration) lets Office offload certain rendering tasks to your computer’s graphics card (GPU) instead of the main processor (CPU). This includes:

• Smooth scrolling and zooming in documents
• Rendering of 3D models, charts, and SmartArt in PowerPoint
• Video playback inside presentations
• Touch and pen input responsiveness
• Transitions and animations in slideshows

When the GPU is capable and drivers are up to date, acceleration makes Office feel faster and more fluid. However, if the GPU driver is buggy, outdated, or incompatible with Office, the same feature can cause visible artifacts, flickering, black boxes, or even application crashes.

How to Disable It in Office 2019

The option is buried in each app’s settings, not in a central Office-wide menu. Follow these steps for Word, Excel, PowerPoint, or Outlook (the steps are identical in all four):

1. Open the application (e.g., Word).
2. Click File in the top-left corner.
3. Click Options at the bottom of the left-hand menu.
4. In the dialog box, click Advanced on the left sidebar.
5. Scroll down to the Display section.
6. Check the box that says “Disable hardware graphics acceleration”.
7. Click OK and restart the application.

Note that the setting is per-app. If you disable it in Word, Excel still uses acceleration until you repeat the steps there. Outlook has the same option under File > Options > Advanced > Display.

Why You Might Need to Disable It

Common symptoms that point to a GPU acceleration problem include:

• Text or images appear fuzzy, blurry, or pixelated, especially after zooming.
• Lines or shapes flicker or leave ghost trails when you scroll.
• Black or white boxes appear where images or charts should be.
• The application freezes or crashes when you open a large file.
• High GPU usage even when the document is idle.
• Screen flickers during video playback in PowerPoint.

These issues are more common on laptops with dual GPUs (integrated + discrete), remote desktop sessions, or after a Windows update that changed driver behavior. Disabling acceleration forces Office to render everything with the CPU, which is slower but far more stable.

When You Should Keep It Enabled

For most users, hardware acceleration is beneficial. If you never notice any glitches, leave it on. Specifically, you want it enabled if you:

• Work with large, complex documents that scroll slowly without acceleration.
• Use PowerPoint’s 3D models, morph transitions, or ink annotations.
• Edit videos or animations within Office.
• Use a high-resolution (4K) monitor where CPU-only rendering can feel sluggish.

Disabling acceleration is a troubleshooting step, not a permanent optimization. If you disable it and the problems go away, the root cause is almost certainly a GPU driver issue. The better long-term fix is to update your graphics driver, not to permanently cripple Office’s rendering.

What Happens When You Disable It

After disabling, Office uses the CPU for all rendering tasks. In practice, you may notice:

• Slightly slower scrolling and zooming on very large documents.
• Less smooth PowerPoint transitions and animations.
• Higher CPU usage during heavy tasks like video editing.
• Improved stability if the GPU was causing crashes or artifacts.

The setting does not affect the document content itself, file formatting, or any calculations. It only changes how the interface is drawn on screen. Your files remain fully editable and compatible with other Office versions.

Common Misconceptions and Related Settings

One common myth is that disabling acceleration improves battery life on laptops. In reality, the opposite is often true: the GPU is far more efficient at rendering than the CPU, so forcing CPU rendering can drain battery faster. Only disable it for stability reasons.

Another misconception is that this setting affects printing. It does not. Printing uses a separate rendering pipeline, so disabling acceleration has zero effect on print quality or speed.

Related but separate settings you might see: “Disable hardware graphics acceleration” is different from “Use hardware graphics acceleration” (which appears in some Office versions) — they are the same toggle, just worded oppositely. Also, if you use a remote desktop (RDP) session, Windows may automatically disable GPU acceleration for all apps; you can sometimes override it with the same Office setting.

If the Problem Persists After Disabling

If you disable acceleration and still see glitches, the issue is likely not GPU-related. Try these steps in order:

1. Update your graphics card driver from the manufacturer’s website (NVIDIA, AMD, Intel, etc.), not just via Windows Update.
2. Run Office 2019’s built-in repair: go to Control Panel > Programs > Microsoft Office 2019 > Change > Quick Repair, then Online Repair if needed.
3. Check for Windows updates, especially display-related patches.
4. Reset Office settings via the “Reset” option in the same repair dialog.
5. If you use a laptop with switchable graphics, try forcing Office to use the integrated GPU in the GPU control panel.

If none of that works, the problem may be with the Office installation itself, not the hardware acceleration. A full uninstall and reinstall of Office 2019 is the last resort.

Frequently Asked Questions

Will disabling hardware acceleration affect my documents?

No. The setting only changes how the interface is rendered on screen. The content, formatting, formulas, and macros are completely unaffected. Your files will open and save exactly the same.

Do I need to disable it in every Office app separately?

Yes. Office 2019 does not have a global setting. You must turn it off in Word, Excel, PowerPoint, and Outlook individually. The steps are identical in each app.

Is this the same as “Use hardware graphics acceleration” in older Office versions?

Yes. In some Office versions the checkbox is worded positively (“Use hardware graphics acceleration”), in others negatively (“Disable hardware graphics acceleration”). They control the same underlying setting. In Office 2019, you check the box to disable.

Why does my Office 2019 not have this option?

The option is present in all desktop versions of Office 2019 for Windows and Mac (on Mac it’s under Word > Preferences > General). If you use Office Online (browser version) or the mobile apps, the setting is not available because those versions do not use hardware acceleration.

Can I re-enable it later without losing any settings?

Yes. Simply uncheck the box in the same location and restart the app. No other settings are changed. You can toggle it back and forth as needed for troubleshooting.

Does disabling acceleration fix high CPU usage in Office?

Sometimes. If the GPU driver is stuck in a loop, disabling acceleration can reduce CPU usage because Office stops waiting for the GPU. But if the high CPU usage is caused by add-ins or large files, disabling acceleration won’t help.
