Arrange it all yourself
Three ways to get on screen. After that, you manage everything yourself in your own customer account.
You book and upload your artwork yourself, in your own customer account. A member of our team reviews your advert before it goes on screen.
Step 1 of 7
Choose a subscription, a campaign or a single event day, then your term, weeks or day.
Next: complete your booking and payment
Step 2 of 7
Check your choice in the basket, fill in your details and pay online with iDEAL. Before you pay, you’ll see your start date and the deadline for delivering your advert.
Next: activate your customer account
Step 3 of 7
New to us? As soon as your payment has been received, you’ll get a confirmation email with a button to activate your account and set a password. Already have an account? Just log in.
Next: view your booking
Step 4 of 7
For each booking, you can see the booked period, the impressions, the spot length and what you still need to do.
Next: upload your advert
Step 5 of 7
Upload your image for each booking as a JPG, PNG or WEBP. It’s automatically made screen-ready (640 × 600) and you’ll see a preview straight away. You have at least five full working days, or two for an event day; the deadline is shown with your booking.
Next: follow the review
Step 6 of 7
A member of our team checks your artwork before it goes on screen. Once approved, your advert is shown according to your booked schedule; if it’s rejected, you’ll see the reason.
Next: find your invoices
Step 7 of 7
For every paid booking, you can open the invoice and download it as a PDF. Instalment invoices for a subscription are listed under Invoices.

About GreenLEDWalls
“In 2019 I started out with one goal: to make smart, affordable and sustainable outdoor advertising accessible to every business owner in the northern Netherlands.” Paolo Assorgia, founder
Practical
A still image; video can’t be shown on the screen. Stick to one short message in a large, easy-to-read typeface: a driver only has a few seconds. You’ll find more tips under Design tips.
Technically accepted: JPG, PNG or WEBP, up to 50 MB and at least 640 × 360 pixels; smaller images turn out too blurry on the screen.
Recommended: submit your artwork at the screen size of 640 × 600 pixels, or in the same aspect ratio. An image that comes close will be cropped to fit. If the aspect ratio is very different, it won’t be uploaded and the portal will ask you to submit the file in the correct format.
You choose whether your advert is on screen for 6 or 12 seconds when you book.
Your artwork is first marked ‘Under review’. A member of our team reviews it before it goes on screen. Your portal will then show ‘Approved’, or ‘Rejected’ with the reason. Approved artwork goes live on the scheduled start date.
In your customer portal. Under ‘My campaigns’ you’ll find your bookings and the status of your artwork; each booking shows the invoice or the invoice status. Log in (the customer portal is in Dutch).
