A user added a heater underneath a desk, and now an external monitor is not working. A technician verified the monitor gets power. Which of the following should the technician do next?
bad catch
The next step that the technician should do is to have the user unplug the heater. This is because the heater may be causing electromagnetic interference (EMI) or radio frequency interference (RFI) that affects the signal transmission between the computer and the monitor. EMI and RFI are types of noise or distortion that can degrade the quality or integrity of data signals, especially in analog connections such as VGA. EMI and
nobody accidentally unplugs a VGA cable, while possessing the ability to ensure power is connected. If a user can check power, yet forget to check the VGA or forget to remember they unplugged it for no good reason.. there is no hope. I am voting A because its the obvious next step, even if the VGA ends up being faulty when we find out it got melted or something.

Who the hell uses VGA anymore?
But yeah, I guess A or D could be valid... Frankly, I would undo the last change first, the user installed the heater, then the monitor stopped working, my first recommendation would be to unplug the heater and see what happens, then check cable if that doesn't work.
It's also very likely he knocked out the cable, now that I think about it, checking that first probably makes more sense than a heater interfering with a monitor somehow.
Heater is underneath the desk but not the monitor. Another note monitor still receives power. User might have most likely disconnected the VGA by accident. There are many scenarios here but I will go with answer D
chat gpt and autopilot confirm answer is A since plugging a heater pretty near to a workstation monitor could cause electric interference with other electric components. I would go with option D but isn't there screws for the VGA cable, which less likely making it loose?
