Track Your Order

Once your order ships, we’ll send a shipping confirmation email with your tracking details and a link to track your shipment.

Please allow up to 48 hours after shipment for tracking information to appear.

If your order has not arrived within the estimated delivery window, contact support@invzi.com with your order number so our team can investigate.

Returns & Refunds

Products purchased directly from invzi.com may be returned within 14 calendar days after delivery.

Opening a product for reasonable inspection, setup, or testing does not automatically make it ineligible for return. Returned products must be complete, free from customer-caused damage, and include the original packaging and included accessories.

For approved non-defective display returns, a $49 return shipping and handling deduction applies. We will disclose the applicable deduction before issuing a return label.

Separately purchased accessories may also be returned within 14 days. The $49 display-product deduction does not apply, but the customer is responsible for actual return shipping unless the return is due to an INVZI error or product defect.

Products purchased through an authorized third-party retailer are subject to that retailer’s return policy.

Please note: Approved returns involving a confirmed product defect, shipping damage, incorrect item, missing included accessory, or inaccurate INVZI compatibility guidance are handled at no return cost to you.

Please contact support@invzi.com or submit a return request through your INVZI account before sending any product back. Return locations vary by product and region.

Customers said this 18.5" portable screen extender provides useful workspace expansion for documents, spreadsheets, and multitasking. Setup requires driver installation and careful cable management. Users appreciate the flexibility for moving between offices, though initial configuration and desk space requirements need consideration.

  • Clear instructions mattered more than a long technical answer.
  • Being able to keep the source beside the draft is the main reason I'd use this.
  • Dashboards benefit from staying visible.

Support intake

Support would be easier if the contact form asked for my laptop model, operating system, and a photo of the connections at the start.

L
Lilliana C.
Documentation navigation

I found the product page easily but had to look around for the manual again. A consistent resources link would make ongoing use simpler.

A
Adrian P.
Resolution clarity

The explanation of the connection sequence helped me find the step I had missed. Clear instructions mattered more than a long technical answer.

N
Nina D.L.
Return information

Before ordering, I want to understand the return process and any applicable costs if the setup doesn't suit my workspace.

B
Blake S.
Troubleshooting relevance

I received general setup instructions when my question was about one screen not appearing. I wanted help with the specific symptom.

K
Katelyn P.
International travel

Before a trip, I want to confirm the supplied charger's electrical ratings and plug arrangement for the destination.

J
Jared L.
Screen cleaning

I need cleaning guidance that covers both the screens and the folded storage surfaces. I don't want to use the wrong material.

S
Serena W.
Joint resistance

A folding joint felt firmer than I expected. I didn't want to force it, so I looked for instructions showing the intended movement.

E
Ethan V.
Packing sequence

Disconnecting and packing the accessories is part of the routine. I keep them together so the next setup doesn't begin with a cable search.

M
Melanie P.
Replacement cable access

I would like a model-specific replacement cable link. Searching through similar-looking accessories is confusing.

M
Mason B.
Included items

A clear photo of everything in the box would make it easier to check the package when it arrives.

C
Camila S.
Heat concern

The housing felt warm during a long session. I wanted guidance on normal operation and when to contact support.

C
Caleb S.
Desk vibration

I noticed movement while typing and wasn't sure whether the desk or the display support was responsible. I would like a checklist for positioning it.

E
Evelyn C.
Stand setup

I want to know how to confirm the rear support is positioned correctly before adjusting the screens.

W
Wyatt F.
Laptop charging question

Does powering the display also charge my laptop in my setup? I need that answered explicitly rather than inferred from the words USB-C or power delivery.

A
Avery M.
Charger replacement

If I misplace the supplied charger, I need clear replacement requirements. The connector shape alone doesn't tell me what to buy.

T
Travis B.
Cable routing

The connections worked, but getting the cables out of my mouse area took some rearranging. A practical desk photo would be helpful.

L
Lydia S.
Cable identification

I have several USB-C cables in my bag. I want an easy way to identify the correct one for this setup instead of trying them at random.

G
Garrett H.
External power expectation

I understood that external power was needed, so I planned my workspace around an outlet. The product photos should make that connection visible too.

C
Carly J.
Purchase decision

I'd like to see someone use ordinary work applications throughout a full setup demonstration. That would help me decide more than another list of occupations.

L
Logan A.
Flexible rooms

I move between a home office and a temporary project room. A setup I can pack away matters more to me than having the smallest possible travel kit.

S
Sabrina R.
Busy versus useful

Filling every display made my workspace feel busy. Leaving an unused screen out of my window layout helped me concentrate.

M
Mitchell R.
Field work constraints

I work away from the office, but not always somewhere with a desk and power. This would only cover part of my travel routine.

K
Kendra E.
Team purchasing

Before buying several, I'd have one person test the setup with the software and laptops our team actually uses.

A
Austin P.
Task switching

Keeping a reference visible reduces the need to find that window again. I can't put a reliable number on how much time it saves.

H
Hailey D.
Too many screens

I thought more displays would automatically improve my workflow. I still had to decide which applications belonged where.

S
Seth W.
Existing desktop comparison

My fixed office monitors already work well. The reason to consider this is travel between locations, not replacing everything at my desk.

V
Valerie S.
Value for occasional use

I like the idea, but I'd only use it a few times a month. That makes the price harder for me to justify.

D
Dustin M.
Customer demonstrations

I need to check what the audience can actually see before using this for a demonstration. My own ideal viewing position may not work for people across the table.

N
Naomi N.
Monitoring versus action

Dashboards benefit from staying visible. For work that needs my full attention, I still focus on one main screen.

B
Bradley C.
Research workflow

Articles, analysis output, and a draft can each stay open. That suits my research process more than dividing one application across every screen.

I
Isabel G.
Video calls

It's easier to keep my notes nearby during a call, but I have to remember where the camera is so I'm not constantly looking away.

More Room for the Work That Matters

Three 18.5-inch Full HD IPS displays turn your laptop into a four-screen workspace for focused work and multitasking.

Keep Your Entire Workflow in View

Keep your main task on your laptop while charts, documents, calls and reference material stay open on three additional displays. Arrange each screen around your workflow and spend less time switching between windows.

A Workspace That Folds with You

Move your setup between home, the office and client sites. The three displays fold together for storage and transport, so you can bring your multi-screen workspace to your next desk.

Space for Charts, Code and Creative Work

View market dashboards alongside research, keep code beside documentation, or spread editing tools and timelines across your screens. Three 18.5-inch Full HD IPS displays give each part of your work its own space.

MAGHUB QUAD MAX FAQ

Questions before you set up

Clear answers about your four-screen workspace.

What is MagHub Quad Max?

MagHub Quad Max adds three 18.5-inch Full HD IPS displays to your laptop: one on the left, one above and one on the right. Together with your laptop screen, they create a four-screen workspace.

Can each screen show a different application?

Yes. With the required driver installed, the three external displays can extend your desktop. Keep charts, documents, code or meeting windows on separate screens, and arrange the displays in your operating system settings.

Do I need to install a driver?

Yes. Driver installation is required for the full four-screen setup. Follow the product setup guide before first use. If your laptop is managed by your employer, check that you have permission to install the driver.

Does it need external power, even with one USB-C laptop connection?

Yes. MagHub Quad Max requires external power and is specified for 45W USB-C PD input. Use the included INVZI 67W GaN charger and follow the setup guide. The USB-C connection to your laptop does not replace the external power connection. Driver installation is also required for the full four-screen setup.

Which charger and travel adapters are included?

Your package includes an INVZI 67W GaN charger and AU, UK and EU travel adapters. This INVZI charger replaces the manufacturer’s original 45W adapter; you receive one charger, not two. The display is specified for 45W PD input, while 67W is the included charger’s maximum rated output.

Does MagHub Quad Max work with Mac and Windows?

MagHub Quad Max supports macOS (2019 and later), including Intel and Apple M-series systems, and Windows 10 and Windows 11. Driver installation is required. Use the included cable setup and follow the instructions for your operating system.

Can I fold it for carrying between workspaces?

Yes. The three displays fold together for storage and transport. Disconnect the cables before packing, and plan for a stable desk surface and external power at your destination.

Does MagHub Quad Max have built-in speakers?

No. MagHub Quad Max has no built-in speakers. Use your laptop speakers, headphones or an external audio device for calls and media.

What kind of work is it suited to?

MagHub Quad Max is suited to workflows that benefit from several visible windows, including trading, coding, content creation and meetings. Use separate screens for your main task, references, dashboards or communication.
