Seems your screen is about to die unfortunately.
To verify this see if you can connect your PC to another LCD screen, if the problem persist it is not your screen but your PC.
In case it is your PC, just clean it out (blow compressed air to remove all dust from your casing) and reinstall driver displays.
Otherwise i'm afraid a new (or used) monitor will be mandatory...

I have an HP L2208w monitor which has been ok for the last two years. Suddenly, it started to display patches of different colours. Also vertical and horizontal colours appear across some pf these patches....


hi steven_katas

Im thinking that this maybe a LCD panel problem (dead pixels) already. some LCD panels last for 2-3 years depending on usage. even if you haven't dropped it or anything the LCD panel's pixels ten to give way slowly or die down since these pixels are like bulbs. here's what you can do. Try connecting a different cable from your monitor to your computer if the issue is still the same, try connecting a different computer or maybe a laptop to your monitor just to eliminate the probability that it can be a cable or a video card problem.
If you have already connected a new computer say a laptop and it is still the same it might already be a hardware problem with your monitor and might need you to bring it to the service center for repair.

Hope this helps please let me know

I HAVE RED DOTS ALL OVER ANY BLACK COLOR OF THE PICTURE


Could be whats known as dead pixels, this is tested be showing up a black or white screen. Microsoft paint or word will do. If an area always has dots then dead pixel. However if it doesn't constantly remain a dot then, some-thing else. Dead pixels come about due to age.
A technician will be able to diagnose your problem by performing white screen test.

What is the recomended resolution display setting for my Acer X193w monitor


Hi there,

A computer monitor is made of pixels (short for "picture element").



Monitor resolution is measured in pixels, width by height. 640 x 480 resolution means that the screen is 640 pixels wide by 480 tall, an aspect ratio of 4:3. With the exception of one resolution combination (1280 x 1024 uses a ratio of 5:4), all aspect ratios are the same.

Hope this initial information helps. Let me hear from you again for any clarifications.

Thank you for using fixya.com

Everything is blury have to set screen resolution to 800by600 pixels to try too make any thing out.


Connect the monitor to a laptop -- is it still blurry?
If so, then the monitor is the problem.
If not, then your computer (the video-card?) is the problem.

Dead pixel


Please read the WHOLE of this guide before starting. Software Method
  1. Try running pixel fixing software. Stuck pixels can often be re-energized by rapidly turning them on and off. If this fails, complete the following steps.

Pressure Method
  1. Turn off your computer's monitor.
  2. Get yourself a damp washcloth, so that you don't scratch your screen.
  3. Take a household pen, pencil, screwdriver, or some other sort of instrument with a focused, but relatively dull, point. A very good tool would be a PDA stylus.
  4. Fold the washcloth to make sure you don't accidentally puncture it and scratch the screen.
  5. Apply pressure through the folded washcloth with the instrument to exactly where the stuck pixel is. Try not to put pressure anywhere else, as this may make more stuck pixels.
  6. While applying pressure, turn on your computer and screen.
  7. Remove pressure and the stuck pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through, which creates the different colors.

Tapping Method
  1. Turn on the computer and LCD screen.
  2. Display a black image, which will show the stuck pixel very clearly against the background. (It is very important that you are showing a black image and not just a blank signal, as you need the backlighting of the LCD to be illuminating the back of the panel).
  3. Find a pen with a rounded end. A Sharpie marker with the cap on should be fine for this.
  4. Use the rounded end of the pen to gently tap where the stuck pixel is - not too hard to start with, just enough to see a quick white glow under the point of contact. If you didn't see a white glow, then you didn't tap hard enough, so use just slightly more pressure this time.
  5. Start tapping gently. Increase the pressure on the taps gradually for 5-10 taps until the pixel rights itself.
  6. Display a white image (an empty text document is good for this) to verify that you haven't accidentally caused more damage than you fixed.

Tips
  • If the pressure and tapping don't work directly on the stuck pixel, start moving outward around the stuck pixel. If you see the pixel flicker while doing this then you know where you can focus the pressure and tapping techniques rather than directly on the pixel.
  • Many people report success with this technique but these instructions won't work in every case. It may take a few attempts to make sure you are pressing exactly on the stuck pixel.
  • These instructions will fix "stuck" pixels, not "dead" ones. Dead pixels appear black while stuck pixels can be one constant color like red, blue or green.
  • An alternative, but similar technique involves gently massaging the stuck pixel with a warm damp (not wet) soft cloth.
  • Alternative technique to tapping: Using a rounded pencil eraser, push with moderate pressure into screen at stuck pixel.
  • If these instructions don't work, you can hopefully get the monitor replaced through your manufacturer. If your monitor falls under the specifications of replacement, get in contact with the manufacturer to set up replacement plans.

Warnings
  • Do not attempt to open the monitor as it will void the warranty and the manufacturer will not replace it.
  • Make sure you don't get any electrical equipment wet or it may break.
  • Some people claim that touching the screen can cause more pixels to become stuck, although this has not been proven.
  • Be prepared to suffer a complete loss; you may crack the glass when tapping or putting pressure on an LCD assembly.

Regarding L1515S 15" LCD Monitor Resolution


Hello mallik, The LCD monitor is actually a active matrix of small transistors (3 for each pixel). They have one native resolution, a FIXED one for example you monitor has 1024 x 768 pixels. This results in 786432 pixels displayed on the screen. Because each pixel is controlled by 3 transistors there will be 2359296 transistors controlling your entire screen. This is a fix number. You can't raise the resolution to 1280 x 1024 because this will require as you can see now... a lot more transistors on the same surface. All you can do is to lower the resolution, in this case 4 pixels (12 transistors) form a larger pixel acording to that lower resolution. The image can look blurry in these situations. THe bottom ideea is that a LCD pannel (more corectly said, TFT (thin transistor film) pannel, has one optimum resolution, it's native one. The higher the better, when choosing one to buy, but you can't raise the resolution over that. You can just lower it. It works different then the normal conventional CRT monitors. Sorry for my bad english as I live in a non english-speaking country. Also if you have anymore questions please post a comment.

Monitor goes blurry, colours/pixels start shaking across screen


Do you have your screen saver enabled, i so turn it off and se if it still does it. Secondly boot your pc in safe mode(pressing F8) on boot up and select start windows in safe mode. See if the monitor still does it, if so a monitor fault or loose/faulty vga lead. If it is ok then your graphics driver may be corrupt and need re installing.
