CompTIA A+ 220-1101 Practice Question

During a presentation, a projector intermittently flashes and goes black before displaying the image again. The presenter confirms that the projector was operating correctly earlier in the day. What should be the BEST next step to troubleshoot this flashing screen issue?

  • Check and ensure the video cable connections are secure between the projector and the source

  • Replace the projector bulb, as flashing can be indicative of a bulb nearing the end of its life

  • Update the video drivers on the connected computer, since this could be causing the flashing issue

  • Adjust the refresh rate settings on the projector since improper configuration can cause screen flicker
