So next we have our flickering image. Now, sometimes we may run into a situation where we may be looking at our monitor, and it seems like there's a little bit of a flicker going on. Maybe not enough that it's a really, really noticeable, but over time it's enough that it can actually make give us eyestrain or actually give us headaches.
Now, this may be a lot of times be due to our low refresh rate.
Refresh rate is the rate at which the number of times per second are monitored refreshes the image. If this refresh rate is set incorrectly, if it's set to low, we may notice a noticeable flickering of our monitor.
So we may, if we have someone that's complaining about having headaches when they're looking at their monitor a lot,
or that there it looks like they're monitor might be flickering a little bit. We want to adjust this refresh late rate higher, so it's not so low.
If we have a distorted image, it may be an incorrect rephrase rush rate as well. We may have a refresh rate that's too high, so we want to check that and make sure we find a nice good balance between the loaf refresh rate of the flickering image or refresh rate that might be too high.
A distorted image might be an indication of a UN supported or too high resolution.
We may have a video card that says, Oh yeah, you can have this really high resolution but we put up that in resolution and our monitor doesn't look right. The image looks distorted. The size of the squares don't look square. They may look rectangular eso
just depending on what our monitor resolution should be and how our video card is trying to force our monitor to that resolution. So we may want to check our resolution.
We may also have a loose video card. We don't want to make sure that we check our video card and make sure that it's secure in the socket and that it isn't loose in any way.
Then we have discoloration with D gauss ing. Now, D Gauss ing is a feature that we only perform on C. R T monitors. C R T monitors cathode ray tube monitors. Our monitors that utilize Met
magnet is a shin in order to display their image. It uses a very strong magnets inside of the monitor to direct beams of beams of color. Essentially that hit the front of our screen and hit a
hit. A panel which is reactive to these these color beams.
there's there's magnets inside of our monitors inside of these gossip inside of the C R T monitors that helped direct those beams. Over time, the magnets may actually cause some discoloration because it'll magnetize a magnetized. Our front panel and the color beams won't
hit correctly on the front of our screen
because there's too much magnetism inside of our monitor. So what we'll do then is will perform something called D ga Zing. Remember this either. Our C o T monitors on Lee R D Ga. Zing. Whoa! With the push of a button or the selective and option will
take, that magnet is a shinin will be magnetized everything for just a moment. It will clear out all that residual D magnets are all that Residual magnetism are magnetism That's on our on our C R T monitor panel that's called causing the discoloration. When you press the D causing button,
you may notice the image like
may go black and come back for a 2nd May waver and start starts seeming like the images going schooling up and down this page before it finally recovers and goes back to normal. And then, after the image has been because after the c R T monitor has been got the cost,
you won't have that image discoloration anymore,
and you'll get it when you do. Gosta Monitor. You might get that nice, soothing room sound of the
the C R T monitor D glossing and de magnetize ing everything
so we'll remember our deep be glossing in order to help for with the coloration and C R T monitors. But as those air phasing out and being replaced by our LCD and led monitors that will become less and less common.
And then lastly, we have our blue screen of death. Yes, there it is again, with our this troubleshooting module are blue screen of death. When it relates to our video applications are display monitor may be a result of a particular display application or an application which is trying to push out certain video feature certain display features
are is going to crash our application, which may crash our computer, and we may get that blue screen of death, maybe
a driver or a video card malfunctioning in causing a just causing a crash of our computer based because our the driver working with the video card isn't functioning properly. We can check that by running in safe mode and running in safe mode with a standard B G. A. Will allow us to check our drivers
and possibly roll them back or update them
or maybe replace our video card. And then blue screen of death can also be based on memory errors. A memory errors may relate to our ram or our memory modules being bad, but we also have video cards which use system memory. There are certain video cards which actually pull memory from our system,
and we'll use that to display high end graphics.
And if those video cards are pulling memory improperly, it may cause a blue screen of death. So we need to check and see if our memory cards are actually causing that blue screen. Are our video cards rather are causing that blue screen of death?
thank you for joining us here today on cyber. We talked about troubleshooting, some common display issues, everything from a blue screen of death all the way to our monitor or our video cards overheating or not displaying properly, we talked about what may be causing certain flickering issues or discoloration or dead pixels.
So hopefully we'll be able to take this information
and you'll be able to use it when you troubleshoot your own monitors. And hopefully we'll see you here again sometime on cyber dot i t.
