The judging room does not contain a TV or any sort of technology for you. Some will have a table or a power cord, but do not assume that it will, as this is not guaranteed and varies based on the venue. My suggestion is plan on bringing everything you will need - table, cart, TV/projector, laptop, even portable battery. You should also be able to adapt to various room setups - You might be in a large classroom with plenty of quiet halls to practice in, or in a dressing room under the bleachers with tons of background noise. Unless you know for sure and confirm with event staff, you should not rely on particular conditions when you enter the judging room. Good luck with your submission!
