For most users this works out of the box and needs no attention. The **Display Settings** panel inside System Settings lets you override that behavior when you need to: pick a specific resolution, force a known-good mode for finicky projectors, or reposition the output for irregular LED walls. The MVP remembers your choices **per display**, fingerprinting each one by its EDID. The next time you plug the same TV, projector, or processor back in, your saved resolution and on-screen geometry are reapplied automatically, even if you've traveled between venues. *** ### Where to Find It 1. Click the **gear icon** in the top-right corner of any page in the MVP web interface. 2. Select **System** to open the System Settings dialog. 3. Expand the **Display Settings** panel (monitor icon). The panel header shows a short summary of the currently active mode. For example, `1920×1080 @ 60 Hz`. So you can see at a glance whether the display is configured the way you expect. If no display is connected, the panel shows **"No display connected. Plug in HDMI to configure resolution and** [**display calibration**](/6.-configuration/display-settings/display-calibration.md)**."** All controls become available as soon as HDMI is detected. *** ### What You'll See When a Display Is Connected
At the top of the panel, the MVP shows: * **Detected**: The display's manufacturer/product name as reported in its EDID (e.g., "Samsung 4K TV"). Shows "Unknown" if the display doesn't report a name. * **EDID**: The first 8 characters of the SHA-256 fingerprint of the EDID block. This uniquely identifies the connected display and is what the MVP uses to look up saved settings. Below that is the **Mode** selector. A single radio group with three mutually exclusive options. *** ### Mode: Auto (Recommended) **Auto** uses the display's preferred mode. The resolution and refresh rate the display itself reports as its native, best-looking configuration. This is the default for any newly-connected display. In almost every case you should leave this set to **Auto**. Modern TVs and projectors advertise their native panel resolution as the preferred mode, so leaving the MVP on Auto guarantees a pixel-perfect, full-screen image with no scaling. Pick **Auto** when: * You're plugging in for the first time and want to verify the display works. * You travel between venues and want each one to "just work" without manual tuning. * The display's native mode is what you want, which is almost always. *** ### Mode: Advanced **Advanced** reveals two dropdowns populated from the modes the display itself reports in its EDID: * **Resolution** — every resolution the display supports, largest first (4K, 1080p, 720p, etc.) * **Refresh** — every refresh rate the display supports at the selected resolution Below these is a toggle: * **Show legacy & interlaced modes** — off by default. When on, the dropdowns also list older VESA timings and interlaced modes (480i, 1080i, etc.), with a small tag showing the source (DTD / Std / CEA).
Use **Advanced** when: * You want to lock the MVP to a specific resolution or refresh rate (e.g., 1080p @ 24 Hz for cinema content). * The display is reporting a non-standard preferred mode and you'd rather use something different. * You want a lower resolution to for a downstream device. > ⚠ **Warning**: Selecting a mode the display claims to support but does not actually drive cleanly may result in loss of signal. If you lose signal, the MVP automatically reverts to the previous working mode after 15 seconds. Do not unplug or power-cycle the device. *** ### Mode: Forced (Universal Override) **Forced** reveals a single dropdown of hard-coded safe modes that are independent of what the display claims to support. The list is: | Mode | | ------------------- | | 1920 × 1080 @ 60 Hz | | 1920 × 1080 @ 30 Hz | | 1280 × 720 @ 60 Hz | | 1280 × 720 @ 30 Hz | | 3840 × 2160 @ 30 Hz | These are the most broadly-compatible video modes. Almost every HDMI device will accept one of them. Use **Forced** when: * A projector or processor has a broken EDID and reports the wrong native mode. * You're routing through a switcher or scaler that needs a specific input timing. A forced mode is **universal**: The MVP applies it regardless of which display is connected, including across hotplugs. Saved per-display profiles are ignored as long as a forced mode is active. To return to per-display behavior, switch back to **Auto** or **Advanced**. *** ### Applying Changes The Display Settings panel is **explicit-apply**. Changing the radio button or a dropdown updates the local form but does *not* push to hardware until you click the **Apply** button that appears in the bottom-right of the panel. Most mode changes take less than a second. You may see a brief black flash on the display while the HDMI link re-initializes. *** ### Display Profiles The MVP creates a profile file for every display it sees, keyed by the EDID hash. These profiles store: * Your chosen mode (Auto / Advanced / Forced reference) * Your [Display Calibration](/6.-configuration/display-settings/display-calibration.md) geometry: where on the physical display the video is positioned *** ### Status Display & Dashboard The Dashboard's **HDMI** card and the front-panel Status Display both show the currently active resolution and the connected device name. After a mode change, these update within a second to reflect the new state. A quick way to confirm a change took effect. *** ### Related Pages * [Display Calibration](/6.-configuration/display-settings/display-calibration.md) — Reposition and resize the video output on the physical display * [System Settings](/6.-configuration/system-settings.md) — Other device-level preferences (LCD brightness, LED, MIDI CC trigger) * [Hardware Connections & Specs](/1.-getting-started/hardware-connections-and-specs.md) — HDMI port details * [Show Day Checklist](/9.-show-day/show-day-checklist.md) — Verifying display output at the venue
