RGBlink VSP 628Pro LED Video Processor
2× 3G-SDI · DVI / HDMI / DP / VGA · loop outputs · dual A/B channels · 22 presets
A rental-grade LED video processor that mixes SDI, HDMI, DVI, DP and VGA sources with full loop-through, processes two independent channels, and feeds LED walls through the sending-card chain — supplied by Excelled, a trusted LED display manufacturer and controller supplier for global B2B system integrators.

RGBlink VSP 628Pro LED Video Processor at a Glance
What is it? The VSP 628Pro is RGBlink’s rental and staging LED video processor — a 1U front-end that scales and switches sources before the sending card, supplied factory-direct by Excelled Display.
What can it take in? Standard: 2× 3G-SDI, DVI, HDMI, DisplayPort and VGA — each with loop-through where the chain needs it — plus optional dual-port input cards for HDMI, DVI, SDI, VGA, USB and CVBS.
How does it reach the LED wall? Through the documented sending-card workflow: the VSP 628Pro’s DVI/HDMI output feeds a sending card (Linsn Port D/U, Colorlight Port A/B), which drives the receiving cards and the wall.
Who is it for? Rental houses, staging companies and event venues that need broadcast inputs, LOGO capture, test patterns and quick preset recall in front of any LED screen brand.
What is included? VSP 628Pro unit with OLED front-panel control, Windows control software and iOS/Android app support — module configuration and pricing from our sales team.
Why the VSP 628Pro Sits in Front of the Sending Card
An LED wall driven straight from a sending card shows exactly one source, unscaled. The VSP 628Pro slots between the sources and that sending card and adds what events actually need: multi-format input with resync and scaling, dual independent channels (A/B), loop-through outputs for monitors and recorders, LOGO capture, and saved views recalled in seconds when a speaker changes at the last minute.
It is built for the truck, too. The front panel runs on a status OLED with a rotary knob and function keys so cuts happen without a laptop, the Windows control software exposes per-image controls from brightness to color temperature, and the iOS/Android app covers adjustments from FOH. The manual documents the full LED chain — including connecting one or both output ports of the sending card to the screen — which is the kind of wiring honesty that saves load-in hours.
Broadcast Inputs
2× 3G-SDI (SMPTE 425M A&B) with loop outputs, alongside DVI, HDMI 1.3, DP 1.1 and VGA-UXGA — all standard.
Dual Channels
Channel A and Channel B work as independent pipelines with their own position and size settings in the control software.
Saved Views
22 load presets recall complete input/output setups; custom output formats cover special LED canvases.
Loop-Through Everything
SDI, DVI, HDMI and Genlock loops feed monitors, recorders and house sync without splitters.
VSP 628Pro Inputs: SDI, DVI, HDMI, DP and VGA — Standard, Looped
The standard I/O covers the event source pyramid: two 3G-SDI BNC inputs at 2.97 Gb/s under SMPTE 425M (Level A & B) for cameras and switchers, DVI-D and HDMI 1.3 inputs for laptops and players up to 1920×1080@60, a DisplayPort input at DP 1.1 carrying WQXGA+ 1920×1200 with 30/36-bit color, and VGA-UXGA on DB15 for legacy machines. Where the signal must continue downstream, the matching loop outputs — 2× SDI, DVI, HDMI and Genlock — hand it on untouched.
| Input (standard) | Connector | Capability |
|---|---|---|
| 3G-SDI | 2 × BNC | 2.97/1.485/270 Mb/s data rates; SMPTE 425M (3G Level A & B), 274M, 125M, ITU-R BT.656; 1080p to 60 Hz; 2× SDI loop out; 150 m at 2.97 Gb/s on Belden 1694A. |
| DVI | 1 × DVI-D | DVI 1.0, 165 MHz TMDS; to 1920×1080@60; DVI loop out. |
| HDMI | 1 × HDMI-A | HDMI 1.3; SMPTE and VESA to 1080p60; embedded audio; HDMI loop out. |
| DisplayPort | 1 × DP | DP 1.1, 10.8 Gb/s; WQXGA+ 1920×1200; 30/36-bit color depth per primary. |
| VGA | 1 × DB15 | VGA-UXGA: 800×600 to 1600×1200 — legacy PCs and document cameras. |
| Genlock | 1 × BNC | Genlock input + loop out; 480i–1080p60 standards incl. 1080psf23.98/24. |
Optional dual-port input modules extend the wall: HDMI ×2, DVI ×2, 3G-SDI ×2 with loops, VGA ×2, USB ×2 and CVBS — the same 93.8 × 17 mm card format across the range, plus the DP 1.2 module (21.6 Gb/s) and the 10G optical fiber module (single-mode, 10 km, 1310 nm, LC).
Driving the Wall: VSP 628Pro to Sending Card to LED Screen
The manual documents the LED connection path precisely, and it is the chain most rental techs already know: the VSP 628Pro processes and scales the program, its DVI/HDMI output feeds the sending card, and the sending card’s ports distribute to the receiving cards and the wall. The documented setups cover one output port (Port D or Port U on Linsn-class cards, Port A or Port B on Colorlight-class cards) and dual-port configurations that split the load across both ports.
- Select the input source — for example DVI — from the front panel or control software.
- Connect the sending card to the VSP 628Pro output, and its Port U/D (Linsn) or Port A/B (Colorlight) to the LED screen’s receiving cards.
- Set the output format in Display Setup — native canvas or a custom resolution for special LED geometries.
- Capture a LOGO if the show needs a holding screen, and save the whole state as a view for one-button recall.
The Windows control software mirrors the panel and adds the deeper tools: Live/Freeze, H/V mirror, hue, brightness, contrast, sharpness, noise reduction, gamma, chroma, color temperature (6500K default), rotation and inverse per image, plus Channel A/B position-and-size fields and the 22-preset Load bank. Test patterns and a factory reset round out commissioning.


Where the RGBlink VSP 628Pro Earns Its Keep
Rental & Staging: One Processor, Any Wall Brand
Because the VSP 628Pro feeds the wall through a sending card, it slots in front of Linsn- and Colorlight-based LED systems alike — the processor choice stops being a wall-brand decision. 22 saved views make the fifth speaker’s layout as fast as the first.
Broadcast-Adjacent Events: SDI In, Loop Out
Cameras arrive on 3G-SDI with loops feeding recorders and routers; Genlock in and out ties the processor to house sync; and the VGA/DP inputs cover the presentation laptops legacy venues still run.
Fixed Venues: Long Runs and Holding Screens
The 10G optical module option carries program 10 km over single-mode fiber for split-site venues, and captured LOGO frames give a clean holding screen between acts without a media player.

VSP 628Pro Buying Guide: 5 Checks Before You Order
- Count the SDI sources first. Two 3G-SDI inputs are standard; camera-heavy shows add the dual-port SDI module — and confirm loop-out needs for recorders before finalizing the count.
- Identify the sending card, not just the wall. The VSP 628Pro feeds Linsn- and Colorlight-class sending cards through DVI/HDMI — know the card model and port plan (single or dual port) before load-in.
- Check for laptop DP output. Modern laptops favor DisplayPort/USB-C; the standard DP input takes 1920×1200, and the DP 1.2 module raises bandwidth to 21.6 Gb/s when 4K-class sources appear.
- Plan the presets around the running order. 22 saved views cover a full show day; map each speaker’s layout to a Load slot during rehearsal and the show runs itself.
- Decide on fiber early. Split-site venues and long throws justify the 10G optical module at order time — fiber runs planned after load-in rarely fit the schedule.

Q1 What is the RGBlink VSP 628Pro LED video processor?
The VSP 628Pro is a rental and staging LED video processor. It takes broadcast and presentation sources — dual 3G-SDI, DVI, HDMI, DisplayPort and VGA — scales and switches them across dual A/B channels, and feeds the LED wall through a sending card, with loop outputs for monitors and recorders.
Q2 How does the VSP 628Pro connect to an LED screen?
Through the documented sending-card workflow: the VSP 628Pro’s DVI/HDMI output feeds a sending card, and the sending card’s ports drive the receiving cards and the wall. The manual covers both single-port and dual-port configurations — Port D or Port U on Linsn-class cards, Port A or Port B on Colorlight-class cards.
Q3 What SDI formats does the VSP 628Pro accept?
The two standard 3G-SDI inputs run at data rates of 2.97, 1.485 and 270 Mb/s under SMPTE 425M (3G Level A & B), SMPTE 274M, SMPTE 125M and ITU-R BT.656 — covering 1080i and 1080p up to 60 Hz, with about 150 m reach at 2.97 Gb/s on Belden 1694A cable.
Q4 What is the maximum input resolution?
The DisplayPort input tops the standard set at WQXGA+ 1920×1200 with 30/36-bit color under DP 1.1; DVI and HDMI reach 1920×1080@60 and SDI runs 1080p60. Optional modules raise the ceiling — the DP 1.2 module carries 21.6 Gb/s for higher-bandwidth sources.
Q5 What are the output options and resolutions?
Standard outputs are one HDMI, one VGA and one DVI-D, each configurable from the standard set or custom — up to 2048×1152@60 and 2560×816@60 under VESA, plus 1920×1080 at 23.98–30 Hz. Custom output formats cover special LED canvas sizes, and a CVBS output module adds PAL/NTSC.
Q6 What are the dual A/B channels for?
Channel A and Channel B are independent processing pipelines, each with its own X/Y position and width/height settings in the control software. They serve dual-screen or dual-zone shows and make A/B program comparison straightforward during commissioning.
Q7 How many presets can the VSP 628Pro store?
The control software exposes 22 Load presets that recall complete input/output states, alongside view saving and recall from the front panel. LOGO capture adds a holding frame for breaks, and custom formats plus a test pattern support commissioning.
