Fix ERROR_GRAPHICS_OPM_OUTPUT_DOES_NOT_SUPPORT_ACP (0xC0262514)
Your video output can't enable analog copy protection because it's not supported. This usually means the monitor or cable doesn't support OPM or HDCP. Here's how to fix it.
Getting error 0xC0262514 is annoying, especially when you're just trying to watch a movie or play a game that uses copy protection. It means Windows tried to enable analog copy protection (ACP) on a video output that literally doesn't support it. The fix is usually simple: swap a cable or change a setting.
What Actually Happens Here
The error comes from the Windows Graphics Kernel, specifically the Output Protection Manager (OPM) subsystem. When software (like a Blu-ray player or a game using DRM) asks the GPU to enable ACP, the GPU checks if the connected display supports it. If the monitor, cable, or adapter doesn't support HDCP (which ACP relies on), the GPU returns error 0xC0262514. The display doesn't speak the right copy protection protocol, so the system bails.
The Real Fix — Check Your Cable and Display
- Disconnect any adapters or converters. HDMI-to-DVI, DisplayPort-to-VGA, Mini DP to HDMI — these often strip HDCP. Plug the monitor directly into the GPU with a single HDMI or DisplayPort cable.
- Test with a different cable. Old or cheap HDMI cables (pre-1.3) don't support HDCP 2.2. Use a high-speed HDMI cable rated for 4K. DisplayPort cables don't need HDCP, but the adapter might.
- Try a different monitor — anything built after 2010 should support HDCP. If it still fails, the GPU itself might be the problem.
If That Doesn't Work — Disable ACP via Registry
If you don't need analog copy protection (most people don't), you can tell Windows to stop trying. This works for DRM-free apps that erroneously request ACP.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]
"DisableACP"=dword:00000001- Open Notepad as admin, paste the above, save as
disable_acp.reg, then double-click to merge it. - Restart your PC.
Why this works: It tells the graphics driver to skip ACP requests entirely. The video output never tries to enable it, so the error never triggers. This is safe — ACP is only used for analog outputs (VGA, component). Digital outputs (HDMI, DisplayPort) use HDCP, which is controlled separately.
Less Common Variations of the Same Issue
1. Dual Monitor with One Non-HDCP Display
If you have a second monitor that doesn't support HDCP (e.g., an old VGA monitor via adapter), the GPU might report that output as unsupported. Unplug it, and the error goes away.
2. Virtual Machines or Remote Desktop
When you RDP into a machine playing protected content, the virtual display driver often doesn't support OPM. The fix: don't remote into a machine that's actively playing DRM content. Use local playback.
3. Custom Resolutions or Refresh Rates
Some custom monitor timings (e.g., 1440p at 120 Hz over HDMI 1.4) can break HDCP negotiation. Reset your display to a standard mode (1080p@60) and see if the error stops.
Why the Registry Fix Is Safe
Let me explain the nuance. ACP is a legacy feature from the analog TV era. It works by corrupting the analog signal if unlicensed recording is detected. Modern displays don't use analog inputs — they use HDMI or DisplayPort, which rely on HDCP. So disabling ACP doesn't affect any normal viewing experience. Only old VGA or component video setups would care, and those are rare now.
Prevention — Stop This Error from Coming Back
- Use the right cable. For HDMI, buy a cable labeled "High Speed" or "Premium High Speed" from a known brand (Monoprice, Belkin, Amazon Basics). Avoid adapters unless you're sure they support HDCP.
- Keep your GPU drivers updated. Nvidia and AMD have fixed OPM bugs in recent driver releases. For Nvidia, use the Studio driver if you're on a workstation; for AMD, the Adrenalin optional driver fixes HDCP handshake issues in some monitors.
- Check your monitor's HDCP support by googling its manual. Many older monitors (pre-2010) don't support HDCP 2.2, but they might support HDCP 1.4. If your source requires 2.2, you'll need a newer monitor.
- Disable ACP preemptively with the registry tweak above if you never use analog outputs. You won't even notice it's disabled.
That's it. Most people fix this by swapping a $5 cable. Don't overthink it.
