HD-VP620 LED Video Processor2-in-1 Sync Processor — 4K@60 Input, 3.9M Pixels, 6 Gigabit Ports, Dual-Window PIP
Huidu HD-VP620 2-in-1 LED video processor with integrated sending card: 3.9 million pixel control through six gigabit outputs, HDMI 2.0 and DP 4K@60Hz input, dual-window PIP/POP, 8 scene presets and Wi-Fi APP control — supplied by Excelled, a trusted LED screen manufacturer for global B2B buyers.

What Is the Huidu HD-VP620 LED Video Processor?
The HD-VP620 LED video processor is a 2-in-1 synchronous all-in-one: a dual-window video processor with an integrated sending card, built for hotels, malls, conference rooms, exhibitions and studios. It accepts 4K@60Hz sources on HDMI 2.0 and DP, switches five input channels at will, and drives 3.9 million pixels through six gigabit outputs.
The front panel adds a full LCD menu with dedicated FUNCTION keys — BLACK, BRIGHT, MODE, PXP, FREEZE and LOCK — so operators run daily changes without a PC, and the built-in Wi-Fi module supports phone APP control.
• Control range: 3.9 million pixels; max width 8000 px, max height 4000 px.
• Outputs: 6× gigabit (650K pixels per port).
• Inputs: HDMI 2.0 (≤3840×2160@60Hz), DP 1.2 (≤4K@60), DVI, VGA, EXT (DVI/SDI option).

Why the HD-VP620 Brings 4K and Dual-Window to One Box
4K@60 Point-to-Point
HDMI 2.0 and DP 1.2 inputs accept 3840×2160@60Hz and display it point-to-point on the wall — the feature fine-pitch conference rooms ask for when laptops output 4K natively.
Dual-Window Without Extra Hardware
PIP overlays a second source inside the main picture; POP places it outside. Live camera over a slide deck, countdown over a loop — layouts that used to need a second processor or scaler now sit in one menu.
FUNCTION Keys for Venue Operators
BLACK blanks the wall instantly, BRIGHT jumps to the brightness menu, FREEZE holds the frame, LOCK prevents mis-operation — physical keys mean the venue staff never touches the software.
HD-VP620 Pixel Capacity Calculator: Will Your Wall Fit?
The VP620 fits walls up to 3,900,000 pixels with a 650K-per-port budget. Check before quoting.
Example 2 — Does not fit: a 4000×1000 strip = 4,000,000 px — just over budget. Result: move up to the HD-VP830 (5.2M px, 8 ports).
General rule: pixel total ≤ 3,900,000, width ≤ 8000, height ≤ 4000, and each port ≤ 650,000 px. Send us your cabinet files for a free load check.
When Should You NOT Choose the HD-VP620?
• Your wall is under 1.3M px with 2 ports — the HD-VP210 costs far less.
• You need 8 outputs or three-window layouts — that is the HD-VP830’s job.
• You need Genlock or broadcast-grade SDI routing — the EXT port covers SDI capture only; true broadcast workflows belong to dedicated switchers.
• You never use 4K or dual-window — the HD-VP410 covers mid-size walls for less.
The VP620 earns its price when 4K input or dual-window layouts are on the table — without them, smaller VP-series units do the job.

How to Connect the HD-VP620 Processor
Six output ports and five input options — plan the port budget before pulling cable.
- Power: AC 100–240V to the power socket; switch on from the front panel.
- Sources: HDMI (4K), DP (4K), DVI, VGA and EXT (DVI/SDI) into the rear inputs; TRS 3.5mm audio in for the analog path.
- Outputs: Cat5e/Cat6 from up to six gigabit ports to receiving cards — keep each port under 650,000 pixels.
- Audio out: TRS 3.5mm to the power amplifier for high-power audio.
- Control: USB-B for PC debugging; Wi-Fi antenna for mobile APP control.

HD-VP620 Setup — Step by Step
The LCD menu plus FUNCTION keys cover daily operation; one-time configuration runs from the PC over USB-B.
- Step 1 — Power up and let the LCD boot.
- Step 2 — Configure the screen: connect the PC over USB-B and set screen parameters and resolution.
- Step 3 — Set input resolution: SOURCE keys reuse as number keys for resolution entry.
- Step 4 — Arrange windows: PXP opens the dual-picture layout menu for PIP/POP placement.
- Step 5 — Brightness: BRIGHT opens the brightness adjustment menu.
- Step 6 — Presets: MODE calls the preset menu — save up to 8 scenes.
- Step 7 — Safety keys: BLACK for instant blank, FREEZE to hold a frame, LOCK to prevent mis-operation.
- Step 8 — Remote: pair the mobile APP over the built-in Wi-Fi for wireless control.

HD-VP620 Common Issues & Diagnostic Procedures
Straight answers from our support engineers’ most frequent HD-VP620 LED video processor tickets.
Q1 How many pixels can the HD-VP620 control?
3.9 million pixels – maximum width 8000 pixels, maximum height 4000 pixels – across six gigabit outputs, each rated for 650,000 pixels.
Q2 Does the HD-VP620 support 4K input?
Yes. HDMI 2.0 and DP 1.2 accept up to 3840×2160 at 60Hz with point-to-point display on the LED wall.
Q3 What is the difference between PIP and POP?
PIP (picture-in-picture) overlays the second window inside the main picture; POP (picture-outside-picture) places it outside the main window. The PXP key opens the dual-picture layout menu.
Q4 Can the HD-VP620 save different configurations?
Yes – 8 scene presets can be saved and recalled with one key press from the MODE menu, ideal for venues that switch layouts between events.
Q5 How does the key lock work?
The LOCK key on the FUNCTION group disables front-panel keys to prevent mis-operation. Press it again to unlock.
Q6 Does the HD-VP620 need a separate sending card?
No. The six gigabit network ports are the sending-card output – they cascade receiving cards directly.
