If you use TallyPrime on a Windows computer equipped with an NVIDIA graphics card, you may encounter an unusual shortcut-key problem:

Pressing Alt+F2 in TallyPrime opens NVIDIA Photo Mode instead of the TallyPrime Period screen.

This can be confusing because TallyPrime itself is working correctly. The problem is usually caused by a keyboard shortcut conflict between TallyPrime and NVIDIA software.

In TallyPrime, Alt+F2 is used to change the period of the company or report. NVIDIA also uses Alt+F2 for Photo Mode on supported systems.

Because NVIDIA's overlay can register its keyboard shortcuts at the Windows/application level, it may intercept Alt+F2 before TallyPrime receives it.

This guide explains why the conflict occurs and provides several methods to fix it.

Quick Solution

If pressing Alt+F2 inside TallyPrime opens NVIDIA Photo Mode:

1. Open the NVIDIA App or NVIDIA overlay.
2. Press Alt+Z to open NVIDIA Overlay.
3. Open Settings.
4. Locate the keyboard shortcut or hotkey settings.
5. Find Photo Mode – Alt+F2.
6. Change Alt+F2 to another shortcut.
7. Alternatively, disable the NVIDIA overlay if you do not use it.
8. Close and reopen TallyPrime.
9. Press Alt+F2 again.

TallyPrime should now display the Change Period screen.

What Does Alt+F2 Do in TallyPrime?

Alt+F2 is an important TallyPrime keyboard shortcut.

Depending on the screen or report you are viewing, it is generally associated with changing the Period.

For example, you may use it when viewing:

• Balance Sheet
• Profit & Loss A/c
• Day Book
• Ledger reports
• Stock reports
• GST reports
• Outstanding reports
• Company information
• Accounting reports

A user may therefore frequently press Alt+F2 while working in TallyPrime.

Example

Suppose your report currently shows:

01-Apr-2026 to 14-Aug-2026

You want to see:

01-Apr-2025 to 31-Mar-2026

Normally you can press:

Alt+F2

and enter the required From and To dates.

If NVIDIA intercepts Alt+F2, however, TallyPrime never receives the shortcut.

What Does Alt+F2 Do in NVIDIA Software?

NVIDIA uses Alt+F2 for Photo Mode on compatible systems/applications.

NVIDIA Photo Mode is primarily designed for gaming and graphical applications. It allows users to capture enhanced screenshots and, where supported, modify visual characteristics before taking the screenshot.

The NVIDIA Overlay also provides functions such as:

• Screenshot capture
• Video recording
• Photo Mode
• Game filters
• Performance monitoring
• Microphone controls
• Instant Replay
• Highlights
• Gallery
• Recording configuration

These features are useful on gaming PCs but are usually unnecessary on accounting or office computers.

Why Does NVIDIA Open Instead of TallyPrime?

The problem is a global or application-level hotkey conflict.

Two applications are attempting to use:

Alt + F2

TallyPrime expects:

Alt+F2 → Change Period

NVIDIA expects:

Alt+F2 → Photo Mode

When NVIDIA's overlay software is active and captures the key combination, it can prevent TallyPrime from receiving it.

Therefore, this is normally not a TallyPrime data problem or TallyPrime software corruption.

Symptoms of the Problem

You may notice one or more of the following:

• Alt+F2 does not open Period in TallyPrime.
• NVIDIA Photo Mode opens.
• NVIDIA overlay appears.
• A Photo Mode message appears.
• TallyPrime appears to ignore Alt+F2.
• Alt+F2 works after NVIDIA software is closed.
• Other TallyPrime keyboard shortcuts continue working normally.
• Clicking the Period option with the mouse works correctly.

These symptoms strongly suggest a shortcut conflict rather than a TallyPrime database problem.

Solution 1 – Change the NVIDIA Alt+F2 Shortcut

This is usually the best solution if you want to continue using NVIDIA's overlay features.

Step 1 – Open NVIDIA Overlay

Press:

Alt+Z

On systems where NVIDIA Overlay is enabled, the NVIDIA interface should appear.

You can also open the NVIDIA App from the Windows Start menu.

Step 2 – Open Settings

Inside the NVIDIA Overlay, locate the Settings / gear icon.

Open the keyboard shortcut or hotkey configuration.

The exact wording and layout can vary depending on the installed NVIDIA software version.

Step 3 – Find Photo Mode

Look for:

Photo Mode

Its assigned shortcut may be:

Alt+F2

Step 4 – Change the Shortcut

Assign another key combination that does not interfere with your accounting software.

For example:

Ctrl+Alt+F2

Choose a combination that is not already used by another important application.

Step 5 – Test TallyPrime

Return to TallyPrime.

Press:

Alt+F2

The Period function should now work normally.

Solution 2 – Disable NVIDIA Overlay

For a dedicated office or accounting computer, this may be the cleaner solution.

If the computer is primarily used for:

• TallyPrime
• Microsoft Excel
• Microsoft Word
• GST work
• Accounting
• ERP applications
• Banking
• Office applications
• Web browsing

you may have little or no requirement for NVIDIA's gaming overlay.

Open the NVIDIA App and locate the overlay settings.

Disable the NVIDIA Overlay / In-Game Overlay if you do not need its capture and gaming features.

After disabling it:

1. Close the NVIDIA App.
2. Restart TallyPrime.
3. Press Alt+F2.
4. Confirm that TallyPrime opens Period.

A Windows restart can also be performed if the shortcut remains registered after changing the setting.

Solution 3 – Close NVIDIA Software Temporarily

If you do not want to modify NVIDIA settings immediately, perform a temporary diagnostic test.

Close the NVIDIA App and related overlay interface.

Then open TallyPrime and press:

Alt+F2

If Alt+F2 starts working after NVIDIA's overlay is closed, you have confirmed that the problem is related to the NVIDIA shortcut.

You can then permanently change the NVIDIA hotkey or disable the overlay.

Solution 4 – Use TallyPrime's On-Screen Period Function

If you need to continue working immediately and cannot modify the NVIDIA configuration, use the Period function available within TallyPrime's interface.

Depending on the report and TallyPrime version, you can use the appropriate Period button or function shown on the screen.

This is a workaround rather than a permanent solution.

Removing the shortcut conflict is preferable.

Solution 5 – Check Whether the Fn Key Is Involved

On some laptops, function keys have multiple functions.

For example, F1–F12 may primarily control:

• Brightness
• Volume
• Wi-Fi
• Keyboard illumination
• Multimedia controls

If F2 itself behaves unexpectedly, test:

Fn + F2

or:

Alt + Fn + F2

However, if pressing Alt+F2 specifically launches NVIDIA Photo Mode, the NVIDIA shortcut conflict is the more likely cause.

Solution 6 – Check Other Applications for Shortcut Conflicts

If disabling NVIDIA Overlay does not fix the problem, another application may be intercepting the shortcut.

Applications capable of registering global keyboard shortcuts include:

• Screen recording software
• Screenshot utilities
• Gaming overlays
• GPU utilities
• Keyboard management software
• Macro software
• Remote-control applications
• OEM laptop utilities
• Streaming software
• Automation tools

Temporarily close unnecessary background applications and test Alt+F2 again.

Solution 7 – Restart Windows Explorer or Windows

Hotkey changes normally take effect immediately, but background software may continue running.

If Alt+F2 remains intercepted after changing NVIDIA settings:

1. Save your work.
2. Close TallyPrime.
3. Restart Windows.
4. Open TallyPrime.
5. Open a report.
6. Press Alt+F2.

If the Period screen now appears, the problem has been resolved.

NVIDIA App vs GeForce Experience

Older computers may still have NVIDIA GeForce Experience, while newer installations are likely to use the NVIDIA App.

Therefore, instructions found on older websites may refer to:

GeForce Experience → Settings → In-Game Overlay

whereas newer installations may refer to the redesigned:

NVIDIA App → NVIDIA Overlay

The interface may differ, but the troubleshooting principle remains the same:

Remove or change NVIDIA's Alt+F2 assignment so TallyPrime can receive the shortcut.

Should You Uninstall the NVIDIA Graphics Driver?

No.

Do not uninstall the NVIDIA graphics driver simply to solve this shortcut problem.

The graphics driver is responsible for operating the NVIDIA GPU correctly.

The conflict generally involves the NVIDIA application/overlay and its keyboard shortcuts—not the basic display driver itself.

Changing the hotkey or disabling the overlay is normally sufficient.

Should You Uninstall the NVIDIA App?

Usually, no.

Start with the least disruptive solution:

Change shortcut → Disable overlay → Test → Troubleshoot further if necessary

Uninstalling NVIDIA software should not normally be required simply because Alt+F2 conflicts with TallyPrime.

Does Disabling NVIDIA Overlay Disable the Graphics Card?

No.

This is an important distinction.

Disabling NVIDIA Overlay does not normally disable your NVIDIA GPU.

Your graphics card can continue providing display and graphics acceleration through its installed driver.

You are simply disabling optional overlay functionality.

Recommended Configuration for Dedicated TallyPrime PCs

For business computers used primarily for accounting, unnecessary gaming features can create avoidable shortcut conflicts and background processes.

A practical configuration is:

NVIDIA Graphics Driver: Keep enabled

NVIDIA Overlay: Disable if not required

Gaming recording features: Disable if not required

TallyPrime Alt+F2: Keep available

This keeps the PC focused on business applications without removing the required graphics driver.

TallyPrime F2 vs Alt+F2

These shortcuts can sometimes confuse users.

F2

F2 is commonly used for changing the date of voucher entry or the date/period applicable to certain reports.

Alt+F2

Alt+F2 is used to change the period.

For example:

F2 → Date

Alt+F2 → Period

The exact function can vary slightly according to the TallyPrime screen being used.

Example of the Conflict

Consider this scenario:

You are viewing the Profit & Loss A/c in TallyPrime.

You need to change the reporting period.

You press:

Alt+F2

Instead of seeing:

Period

you see:

NVIDIA Photo Mode

This indicates that NVIDIA captured the keyboard command before TallyPrime.

After changing or disabling NVIDIA's Alt+F2 hotkey, pressing Alt+F2 should again control TallyPrime.

How to Confirm the Problem Is Fixed

Perform this simple test.

Test 1

Open TallyPrime.

Test 2

Open a report such as:

Balance Sheet

or

Profit & Loss A/c

Test 3

Press:

Alt+F2

Expected Result

TallyPrime should allow you to select or change the reporting period.

Incorrect Result

If NVIDIA Photo Mode or another application still opens, another hotkey handler remains active.

Troubleshooting Checklist

If Alt+F2 still does not work, check the following:

1. Confirm TallyPrime is the active window.
2. Test the Alt key independently.
3. Test the F2 key independently.
4. Check whether the laptop requires the Fn key.
5. Close NVIDIA Overlay.
6. Change NVIDIA's Photo Mode shortcut.
7. Disable NVIDIA Overlay temporarily.
8. Restart the computer.
9. Close other screen-recording utilities.
10. Check keyboard macro software.
11. Test another keyboard if available.
12. Verify that other TallyPrime shortcuts work.
13. Test Alt+F2 in another TallyPrime report.
14. Update TallyPrime if you are using an outdated version.
15. Update or reinstall NVIDIA software only if its settings appear corrupted.

What Not to Do

Avoid unnecessary troubleshooting such as:

• Reinstalling TallyPrime immediately
• Deleting TallyPrime data
• Rewriting company data
• Reinstalling Windows
• Removing the NVIDIA graphics driver
• Formatting the computer

A keyboard shortcut conflict generally does not require any of these actions.

Technical Explanation

Windows applications can register keyboard combinations for application-specific or broader functions.

TallyPrime expects Alt+F2 when the TallyPrime window is active.

NVIDIA's overlay functionality may also monitor the same combination.

When NVIDIA processes the keyboard event first, TallyPrime may not receive the expected input.

Changing the NVIDIA hotkey removes this collision.

Conceptually:

Keyboard → Alt+F2 → NVIDIA Overlay → Photo Mode

After correction:

Keyboard → Alt+F2 → TallyPrime → Period

This is why reinstalling TallyPrime generally does not solve the underlying problem.

Additional Tip for IT Administrators

If you manage multiple accounting computers, create a standard workstation configuration.

For example:

• Keep required GPU drivers installed.
• Disable unnecessary gaming overlays.
• Remove unnecessary startup applications.
• Standardize TallyPrime versions.
• Keep Windows updated.
• Document application hotkeys.
• Avoid assigning global shortcuts that overlap with accounting software.
• Test business-critical keyboard shortcuts after installing GPU, recording or remote-access utilities.

This can prevent similar complaints across multiple PCs.

Frequently Asked Questions (FAQ)

1. Why does Alt+F2 open NVIDIA instead of TallyPrime?

NVIDIA Photo Mode can use the same Alt+F2 keyboard combination that TallyPrime uses for changing the period. NVIDIA's overlay may therefore intercept the shortcut.

2. What does Alt+F2 do in TallyPrime?

Alt+F2 is used to change the period in supported TallyPrime screens and reports.

3. What does Alt+F2 do in NVIDIA?

NVIDIA uses Alt+F2 as the shortcut for Photo Mode on supported systems and applications.

4. Is my TallyPrime installation corrupted?

Usually not. If NVIDIA Photo Mode appears when Alt+F2 is pressed, the problem is most likely a keyboard shortcut conflict.

5. Will changing NVIDIA's shortcut damage TallyPrime?

No. The NVIDIA hotkey and TallyPrime application are independent.

6. Can I completely disable NVIDIA Overlay?

Yes, if you do not require its recording, screenshot, Photo Mode, filter or gaming overlay functions.

7. Will disabling NVIDIA Overlay disable my graphics card?

No. Disabling the optional overlay does not normally disable the NVIDIA GPU or its display driver.

8. Should I uninstall the NVIDIA graphics driver?

No. The graphics driver itself should generally remain installed.

9. Do I need to reinstall TallyPrime?

Normally no. First remove the Alt+F2 shortcut conflict.

10. Why does Alt+F2 work after closing NVIDIA software?

That strongly indicates that NVIDIA's overlay or hotkey service was intercepting the key combination.

11. Can I use another shortcut for NVIDIA Photo Mode?

Yes. NVIDIA provides options to customize various overlay hotkeys.

12. What is the shortcut to open NVIDIA Overlay?

On supported NVIDIA configurations, Alt+Z is commonly used to open NVIDIA Overlay.

13. My PC has NVIDIA graphics but Alt+F2 works normally. Why?

The NVIDIA Overlay may be disabled, Photo Mode may not be active, or your NVIDIA configuration may not be intercepting that shortcut.

14. Can this happen on laptops?

Yes. NVIDIA-equipped laptops can experience the same conflict. Laptop Fn-key configuration can introduce an additional variable.

15. Alt+F2 still doesn't work after disabling NVIDIA. What should I do?

Restart Windows and test again. If the problem continues, check other applications capable of registering global keyboard shortcuts.

16. Can screen-recording software create similar problems?

Yes. Recording, streaming, screenshot, keyboard macro and gaming utilities can use global shortcuts.

17. Is Alt+F2 required for entering vouchers?

Not necessarily, but it is an important productivity shortcut when changing periods and working with reports.

18. Can I change the TallyPrime period without Alt+F2?

Yes. Period functions can also be accessed through the appropriate TallyPrime interface depending on the screen.

19. What is the difference between F2 and Alt+F2 in TallyPrime?

F2 commonly relates to changing a date or report period depending on context, while Alt+F2 is specifically used for changing the company/report period in applicable screens.

20. Is this problem related to TallyPrime company data?

No. A keyboard shortcut collision is normally unrelated to the integrity of your TallyPrime company data.

Conclusion

If Alt+F2 opens NVIDIA Photo Mode instead of Change Period in TallyPrime, there is usually nothing wrong with your TallyPrime installation or company data.

Both applications are attempting to use the same keyboard combination.

The preferred solution is to:

Open NVIDIA Overlay → Settings → Keyboard Shortcuts → Change or disable Photo Mode Alt+F2

If NVIDIA Overlay is unnecessary on an accounting workstation, you can instead disable the overlay.

After resolving the shortcut conflict, reopen TallyPrime and test Alt+F2. The shortcut should once again allow you to change the required reporting period.
