Answers before you ask.

U-Vision carries content from HKU entities — faculties, departments, offices, centres, and registered student societies. Submit on behalf of your entity rather than as an individual; personal projects are not eligible. As for getting it to us: if your HKU account has Microsoft 365 access, you can submit directly. Students, student societies, RPg students, staff with a departmental account, and anyone else without Microsoft 365 access ask a HKU staff member who has Microsoft 365 access to submit for them, or contact the U-Vision team for help.

Promotions relevant to the HKU community — events, programmes, research and university brand or campaign content. One image (.jpg/.png) or video (.mp4) per submission, up to 200 MB, in landscape or portrait to match your chosen format.

Submit at least 3 business days before your start date. That window covers the review and getting your content onto the screens; public holidays don’t count towards it. For a video wall or the escalator arrays, allow at least a week — those are arranged with the team by email rather than through the form.

Keep it short — we recommend 15–30 seconds, and it must not run longer than 3 minutes (180 seconds). If your file is over 200 MB, compress it first with the free HandBrake (opens in new tab) app or freeconvert.com/video-compressor (opens in new tab).

You can indicate an orientation and preferences, and the team schedules across the network. Exact per-screen placement isn’t self-selected. If a particular zone matters for your audience — Centennial Campus or the student residences, say — tell the team when you submit and we’ll do our best, though we can’t guarantee it. Video walls and escalator arrays are the exception: those are booked directly with the team by email.

Usually a technical issue (wrong format, over 200 MB, wrong orientation) or a content issue (unreadable at distance, off-brand, or not relevant to the HKU community). Following the guidelines clears almost all of these before you submit.

Viewing, editing and withdrawing happen inside the submission app under “My Submissions” — not on this website. While your submission is under review you can’t edit it: withdraw it and submit a new one instead, so a reviewer never approves a version you’ve already replaced. Once it’s approved you can change the display dates and upload a new version once; that revision goes back for review before it runs. If the team requests a change, you’ll get an email explaining what’s needed.

No. U-Vision is free for all HKU entities.

Up to 60 days. If you want a message up for longer than that, we’d rather you refreshed the creative and submitted again than left the same frame running — people stop seeing content they have already walked past for two months.

A video plays for its own length, so a 30-second video gets 30 seconds. A still image or poster gets 10 seconds. How often your content comes round depends on how much is scheduled at the time, so there’s no fixed interval we can promise.

The form needs your HKU account to have Microsoft 365 access. If you expect to have it and the form still won’t let you in, check your Microsoft 365 subscription with ITS. In the meantime you can ask a colleague with Microsoft 365 access to submit on your behalf, or email the U-Vision team and we’ll help.

Use the U-Vision contact page — it’s the single support channel, so you don’t have to guess between IT, CPAO or a vendor. Email reaches the team directly.
