Question about ViewSonic VP191b 19" LCD Monitor

1 Answer

Running pixelation On areas of a specific tonal/grey value I see running pixellation that appears red in color. For example, on the Window title bar it will appear in bands. In images it will appear throughout the image where the grey value is equal. It happened during my warranty but the shop, which had it for a week, insisted there was no problem. Now the warranty has expired and the problem has come back. I have tested it with my laptop and the problem is identical so I doubt it is the video card. I have tried powering off the monitor and, while that seemed to work earlier, it has no effect now.

Re: running pixelation

It?s possible the shop may have been right. From your description it sounds similar to problems I?ve had on a few computers in the past; in fact I have one I need to test on Monday morning as well. For me this has usually been a video card/driver problem, I suggest you connect this monitor to another PC. Some LCD monitors have a video cable that is removable. If yours does make sure you use another cable you know works and not the one from your PC. If the problem follows the monitor then I would take it back ask for the manager and try to nicely convince him/her that this repair should be under the warranty since you had brought this to their attention while it was in effect. If the problem doesn?t follow the monitor then the next thing to try is connecting another monitor to your PC to see if the problem reappears. If you can?t do this then the only other option is to assume the problem is your computer hardware or software. - Remove the video cable where it plugs into the PC and check it for bent pins, corrosion; replace and firmly reconnect using the thumbscrews on the connector. - Some LCD monitors have removable cables some don?t; if yours does follow the same procedure outlined above. - If your monitor has a removable video cable try switching it with another one you know works. - Find, download and install the latest driver for your video card, restart and test. - If your video card is not built into your motherboard then remove and reseat the card in its slot and test. - Try another video card in your PC. Tell us the results and please let us know if you have any other questions; thanks in advance for rating this posting.

Pixelated appearance

Hello Anon, it seems you may be looking at a driver conflict here. Setting up this project is easy; bring in a second monitor and prepare to swap between the two frequently.

1. On the Eizo's menu initiate the self calibration.
2. When the Eizo completes the self calibration and the Pixelation persists, uninstall all the Graphic Card drivers on your computer.
3. Install the manufacturer's specific graphics card drivers from the manufacturers website.
4. If the monitor continues to be pixelated then ensure that your GC is 4k ready. (That it can natively display 2560x1440 @ 16:9 aspect ratio).

I suspect your Graphics Card is not up to par, it likely has full 1080 but not enough to push 4k as your monitor natively runs. Purchase any GC with a 4k ready capacity and you will enjoy the full beauty of your purchase.

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 does it mean by dead cells?

I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Lcd tv with wrong color on one pixel

LCD screens occasionally have what are called "Stuck pixels". There is a tutorial in wikihow which might help you out here:

Try that and see if it helps. Stuck pixels are actually a slighty common 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.

  • 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.

A line of Dead Pixels.

You are right it is a stuck or dead pixel, usually if it is a colred line but not grey it is a stuck pixel at the beginning of the line you can try a utility designed to flash bright colors repetedly over time to see if this will "unstick" it. Also you could have a dry joint on your TCP which would require opening it up to diagnose.

Red pixels on the Srceen

Dead or stuck pixels are not uncommon in LCD displays, and the less you pay, the more likely it is to happen (as a general rule) Most manufacturers will a dead pixel warranty, ranging from 7 days to lifetime.

Read your warranty carefully, and speak to the place where you bought your display.

I hope that helps, if you have any further problems, please add them ass comments to this question. If I have been able to answer your question (or not) please click on one of the ratings buttons to let everyone know how I did.
