Re: small ?warm? traveling in my screen

Is this happen when your PC fully boot up? have you seen them during the initial boot up or when you open the BIOS setting screen? If you can see in BIOS setting screen chances are something wrong with your monitor... If not.. get different antivirous scan again... worst case reformat the hard drive reinstall the O/S...

How do I fix the resolution it is was to big

if you are in Xp right click on the desk top. go to Proporties, goto Settings, use the slide to adjust the screen size of the pixel resolution you want. click apply.

the smaller the number the bigger the font. so an 800 x 600 is huge where as a 1920 x 1080 is small. (you can have different resolutions it doesnt matter your screen size physically)

THERE is two small bright patches in the screen

the two small bright patches are actually bad pixels.there is nothing to worry about as upto 5-6 bad pixels are fine.these bad pixels do not spread generally so no reason to case the number of bad pixels on the screen increase to more than 5-6 then you can get your unit replaced by the manufacturer if in warranty.

My dell monitor has three large green shimering boxes across the bottom of the screen that I can't get to go away. Powered on and off, unplugged, plugged....

Shimmering boxes and/or LCD screen has spots = this is due to Missing /broken Pixels.
- These are pixels that are permanently off and is a natural defect that occurs in LCD technology.
Solution (1) = Do a reset on All Settings.
Solution (2) = If Solution(1) does not work, you may need to replace your monitor.

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.

  • 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.

  • 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.
