This is less than 15.4 troubleshooting video display issues.
00:06
As a technician out in the field, you will come across a lot of situations where you met the troubleshoot, different video problems. So we're going to step through some common video troubleshooting situations. Kind of help you for your role as a I T technician in the field.
00:24
No video. A lot of times you'll come across this where there is a monitor connected to a device and you're getting absolutely no vehicle.
00:32
First thing you wanna check is is the cable connected again? The most easiest question could be the problem is the cable connected.
00:40
You want to check the power cable also, and you want to check the signal cable. Make sure those cables are not lose. Make sure the power connector is plugged in.
00:50
Check the input settings. The selection could be wrong to make sure that the input is on the correct setting. Sometimes on an LCD MTA Roy, a TV monitor. The input could be selected to HD Am I when you're expecting it to work on V G. A. And vice versa.
01:07
So check the aged. Am I checked a devi I check V g. A. Make sure that the input setting
01:11
is correct for the type of device that's going to be sending the signal to that monitor.
01:17
Sometimes you'll have a dim image to images. Dim. Swap the monitor with a different monitor. Use a different model to see if it's dim on that Mahler that will help you troubleshoot to see if it's the monitor or the laptop with computer. Sometimes you may have no video after Windows loads
01:34
that could be a video driver issue.
01:38
Ah, use V G a mode on the V G. A. M O is in no way to troubleshoot that, because VJ mode can work with really any monitor display
01:49
image quality problems, flickering or color patterns, this could be an easy fix. What you want to do is first check your cable, make sure that came appeals and are bent are missing. This could be the root cause of that issue, or if your image is distorted and the geometry is distorted,
02:05
check the OS or the operating system refresh rate and the resolution settings thes studies need to match.
02:10
You could have a monitor that's requiring a 60 megahertz and the operating system is set to 50. Check those settings to make sure that they do match.
02:20
Also, check your cables. It could be a cable problem, but make sure that cables are in good working order, and it's a snug fit.
02:28
Also, what you may want to do is look at your hardware acceleration. You may have to disable the hardware acceleration. That could be the cause of the problem as well.
02:37
Image quality problems, oversized image and icons. You wanna check the resolution? The resolution could be set to low, and another common problem when you have video images on a monitor for a long period of time without any change it could be burning in common across many different monitors is burning
02:58
to resolve the issue of burning in many common modern monitors. Now we'll have something called pixel shift. Pixel shift is used to prevent Bernie. It's basically what will happen is the monitor will sense that an image it is not changing a refreshing and will gradually shift pixels to prevent Bernie. Um,
03:16
now this is something that's transparent to the of the viewer of it, because you would not even notice that the pixels are shifting.
03:23
But this is a way that monitors can prevent burning.
03:28
Sometimes L cities can have an image that sticks the related to pixel problems, stuck pixels or dead pixels. That's in a situation where there could be, ah, problem with the device or the display.
03:42
She also have something was called artifacts. Unusual graphics checked your adapter, your video adapter image. Persistence. Turn off your monitor and the image is still there are or motion trails disable advanced video features that will help you resolve that issue.
04:00
Sometimes you may have the blue screen of death and overheating. This could be one of many different problems. It could be your video drivers. You want to monitor the temperature on that video card as well, sometimes in that device, and gets really hot internally inside that case. And you wanna have the monitor in the internal
04:18
temperature inside that case as well.
04:21
It may be a problem where you need a better fan or better ventilation for the system, and it could be causing the overheating, which would thus result in the blue screen of death errors and overheating. Okay, so what we've done this lesson is we discussed different ways to troubleshoot your video display issues. Ah, wide range of
04:40
troubleshooting steps that you would need to know for the county. A plus as well as
04:44
your role, is a technician out in the field. So that is it for this lesson, and we will see you in the next lesson.
