# FAQ

## What is the latest stable version?

The latest stable release is 1.6x (1.69). Features labeled **BETA (v2)** in this chapter require a v2 beta build.

## Which features are BETA (v2)?

Any feature marked **BETA (v2)** is only available in v2 beta builds. Examples include Nobe Connect and the new NDI audio options.

## Do I need an NDI license?

NDI streaming features require an NDI license. Use **License > Upgrade to NDI...** to upgrade an existing license. See [Upgrading to NDI](https://docs.timeinpixels.com/nobe-display/upgrading-to-ndi).

## Does Nobe Display support Apple Silicon?

Yes. Native Apple Silicon support was added in 1.63.

## I didn't receive my license key after purchase

The license key comes in a separate email from `timeinpixels.com` — not the Paddle receipt. Check your spam folder first. If it's still missing, visit [timeinpixels.com/lost-license](https://timeinpixels.com/lost-license/) and enter the email used at checkout. If no license is found, the checkout email may contain a typo — contact support with your purchase details so we can look up the order.

## My activation fails with "License not found" or a signature/SSL error

Use the **Activation Code** method instead of email + key. It validates locally and bypasses firewalls, antivirus, and corporate proxies.

1. Check your key prefix first: Nobe Display keys start with `DDN1` (NDI) or `DDS1` (Studio). Keys starting with `NMTR` are OmniScope trial keys and won't activate Nobe Display.
2. Log in at [timeinpixels.com/my-license](https://timeinpixels.com/my-license/), click **Get Activation Code** next to your license.
3. In Nobe Display, open the **License** menu and paste the activation code.

Full instructions: [License Activation → Activation Code](https://docs.timeinpixels.com/license/license-activation#activation-code).

## I got "Exceeded number of activations" — how do I reset?

This happens after a machine is wiped or replaced without deactivating Nobe Display first.

1. Log in at [timeinpixels.com/my-license](https://timeinpixels.com/my-license/).
2. Click **Reset** next to the machine you want to release. Reset requests are approved manually, usually within a few hours during business hours.
3. Once approved, activate on the new machine.

One license activates on up to **3 machines simultaneously** for Nobe Display. If deactivation inside the app fails with a runtime error, open the logs folder, delete the `DDS1.dat` or `DDN1.dat` file, restart, and activate again.

## How do I change the email address on my license?

Customers can't self-service this — contact support with your old email, new email, and (optionally) license key. After the change, deactivate and reactivate on your machines so the new address is stored locally.

## The Nobe Display plugin doesn't appear in DaVinci Resolve

1. **Launch the Nobe Display app first, before opening Resolve.** The first launch installs the OpenFX plugin on macOS.
2. Open Resolve — the plugin should appear in the Color page → Effects panel → OpenFX.
3. If it's still missing or shows "Failed to load", reset the OpenFX cache: see [OpenFX Plugin is Not Loading](https://docs.timeinpixels.com/nobe-omniscope/troubleshooting/openfx-plugin-is-not-loading).
4. From inside the Nobe Display app, use **Options → Install Plugins → Install OpenFX Plugin** to force a reinstall.
5. If you're running Resolve from the Mac App Store, see [DaVinci Resolve from the App Store](https://docs.timeinpixels.com/nobe-display/davinci-resolve-from-appstore) for the sandbox workaround.

## The Nobe Display window is black or plays back on its own

The most common cause is DaVinci Resolve's **render cache** interfering with the OpenFX frame delivery. Disable it:

* **Playback → Render Cache → None**, and turn off **Cache Frames in Background**.

If you need smooth playback of heavy media, use **proxy media** instead of the render cache — proxies don't cause this. For a permanent fix, use a hardware capture card (DeckLink or UltraStudio) as the signal path: SDI output from Resolve is not affected by caching behavior.

## My color-managed timeline (DWG / ACES) looks flat or log in Nobe Display

Place the Nobe Display node at the **end** of your node chain so the color transform is applied before the signal reaches the plugin. See [Color Managed Timeline](https://docs.timeinpixels.com/nobe-display/color-managed-timeline) for the full setup.

## Can I use multiple Nobe Display nodes in one Resolve project?

No. Nobe Display 1.x cannot differentiate frames from multiple OFX instances at once. Multi-instance support is planned for a future version — use a single Nobe Display node per timeline for now.

## What does the OpenFX plugin NOT pass through?

The OpenFX architecture only delivers the composited frame. The following are **not** visible to Nobe Display via the OFX path — use a hardware capture card if you need them:

* Power windows, qualifiers, and masks
* Split view / image wipes
* Gallery stills
* Reference clips

## Nobe Display 1.x crashes when receiving NDI from an external source

Known issue — Nobe Display 1.x ships with an older NDI SDK that can crash when connecting to NDI sources from other applications (e.g. OmniScope on another machine, VR headsets). The **Nobe Display 2.x beta** uses a newer NDI SDK that fixes this. Grab it from [timeinpixels.com/nobe-display-beta](https://timeinpixels.com/nobe-display-beta/).

## Why is there lag between Resolve and Nobe Display?

OpenFX queuing in DaVinci Resolve adds latency that scales with timeline resolution and color pipeline complexity. There is no user-accessible control for this. For consistent low-latency output, use a hardware capture card (DeckLink or UltraStudio) instead — SDI output is unaffected.
