Exam 220-1001 topic 1 question 30 discussion

Its actually A & B. For correcting Artifacts- Its Updating the video Drivers -A+ TextBook and for DIM Screen-Increase the projector Contrast. I had this same ques on exam,BTW

This question is a bit tricky. The word artifacts could mean a variety of things. Often it could mean dead pixels, or old images that aren't changing quickly, or bad resolution, or just relative visual issues. If the visual artifacts are dead pixels, it may be piece of the projector needing to be replaced. Contrast should help with brightness and the aspect ratio will allow it to fit the screen correctly. Projectors are a normal job encounter though so make sure to document what projectors you have, how often bulbs need to be replaced, and what vendor you go through as they'll probably need maintanence once or twice a year in high-use settings.

The correct answer is A&E because when a different laptop is connected to the projector, the IMAGE APPEARS TO BE CORRECT but is very DIM.” So the image is in focus and doesn’t need (B) adjustment to contrast or (D) change the aspect ratio or (F) modify the display resolution. The problem is 1) the original laptop displays artifacts – solution: update drivers — and 2) the image is very dim: solution: install a new bulb.

A. Update the video drivers on the laptop: Outdated or incompatible video drivers can cause display issues and artifacts. Updating the video drivers to the latest version can help resolve compatibility issues and improve the display performance. E. Replace the bulb in the projector: A dim image on the projector can be indicative of a failing or worn-out projector bulb. Over time, projector bulbs lose brightness and need to be replaced. Installing a new bulb can restore the brightness and improve the image quality.

I think A & B

AB most correct,

Artifacts on display issue Overheating video card (GPU) : check the fan on the video card and replace the fan or card if defective. If the card is overclocked, reset it to normal operations. Overheating computer : Check the fan o the CPU heat sink and replace the fan if defective. Clean case fans and air intakes.

Artifacts are usually caused by advanced video features So its hard to say weather the answer is A or D for that,The option for the dim-ness is obviously B no doubt.

B&D are the right answers. Professor Messer explained both clearly. Video Title: Troubleshooting Video and Display Issues - CompTIA A+ 220-1001 - 5.4. Answer B, change contrast to remedy dimness. Answer D, Change the ratio in order to get rid of artifacts on the screen.

a bit strange question. Any other idea?

After analizing the question i ended up agreeing with the answer, remember compTIA is very specific about giving you the easy analysis to confuse you, of course AB or AE sounds more logic, but i will try FIRST AS THE FOLLOWING STEP change the projector aspect ratio since it can be configured differently from the laptops output display.

I am taking demo exams on a course I got in online (paid) and a similar question came stating the answer to a dim projector light is: "change the bulb". So I would say E (change bulb) would be the correct answer, (unless changing the contrast would be considered a cheaper non-invasive solution). As for the second answer, "A" would make the most sense as that would solve the artifacts issue on the laptop! My exam is in a few hours so I'm really just sitting here, going through these questoins scared shitless from all this confusion!

So I am going to take my exam in two days. Which two is the correct answer I am really confused

Thank you

The question states that the picture is correct but dim. Why would I need to change the aspect ratio or resolution if the picture is correct?

A – update the video drivers E – replace the bulb [question says: “When a different laptop is connected to the projector, the IMAGE APPEARS TO BE CORRECT but is very DIM.” So the image is in focus and doesn’t need (B) adjustment to contrast or (D) change the aspect ratio or (F) modify the display resolution. The problem is 1) the original laptop displays artifacts – solution: update drivers — and 2) the image is very dim: solution: install a new bulb.

The answer is correct, the artifacts issue has already been solved by connecting a different laptop. The issue to be solved is the dimness (picture quality) which can be solved by the chosen answers.
