It depends. If your presentation requires sound including music or dialogue, you will need to rent PA equipment to project the audio. You will also need to rent a projector screen to show your presentation. If you have a slide show or presentation, you will need a laptop with the proper VGA Out connection or the necessary adapters to accommodate the projector. TSV will have many of the cords and adapters necessary to accommodate most laptops and will consult with you prior to renting all equipment.
