Your monitors Horizontal section has gone faulty... some components have gone out of tolerence.. and this is what is making the picture streach out. I think it's gonna be a job for the "Shop" Ensure that you get a firm "Quote" B4 you proceede.

LG L194WT picture problem


Sounds like your main board is going out. It's cheaper to buy another monitor then fixing it unless you have a warranty.

Tip

Monitor buying tips you should know.


Over the years monitors have transformed from those bulky CRT monitors to square LCD screens to stylish flat wide screen LCD's and now to new stylish extremely thin LED screens. On average every PC user spends at least 5 hours a day looking at the monitor. If the picture is fuzzy and not clear enough then there is a very high possibility that the eyes get damaged.

Monitor Sizes
There are many different sizes of CRT, square LCD, wide LCD and wide LED monitors available on the market at the moment.

If you want an older CRT screen then sizes can range between 14" to about 20", they use the 4:3 aspect ratio.
If you want an older LCD screen then sizes can range from 15" to 19", they also use the 4:3 aspect ratio.
If you want a newer wide screen LCD then sizes can range from 18.5" to about 27" and even larger. They use the 16:9 if they are full HD or 19:10 if they are not ratio.
If you want a newer wide screen LED then sizes can range from 18.5" to about 27" and even larger. They also use the 16:9 if they are full HD or 19:10 if they are not ratio.

Image quality
The sharpness of the image in a monitor greatly depends on your Graphics card as well as whatever resolution you are running at. Nevertheless the quality of the monitor plays an important role.

Here are some of the tips that you should know before buying a monitor.

1. There are three types of monitors namely CRT, LCD and LED. The monitor that looks like a TV is a CRT monitor. In CRT monitors there is a Cathode Ray Tube that shoots electrons into the screen to create the image. An LCD monitor is smaller in width and consumes less power and is healthier if you are going to be spending large amounts of time at your PC. The LED screen looks the same as an LED monitor and the difference between it and the LCD is that it has a much higher contrast ratio resulting in darker blacks and much lighter whites.

3. A CRT monitor is much heavier than LCD monitor as you can imagine by it's bulky appearance. A LCD monitor is very lightweight and so is a LED monitor.

4. The distance between two adjacent pixels in a monitor is called 'dot pitch'. This is measured in millimeters (mm). Smaller the dot pitch the clearer the picture quality. Usually there are monitors with dot pitch varying between 0.20 mm to 0.27mm. Some manufacturers use diagonal dot pitch while most of them use horizontal dotpitch. The diagonal dot pitch is always longer than the horizontal dot pitch

5. Resolution of a monitor has to be considered with care. Most of the CRT monitors have resolutions of 800×600, 1024×768 and 1280x1024. The square LCD monitors have 1280×1024 and 1600×1200 resolutions. Newer wide screen LCD monitors have resolutions of 1600x1900, 1680x1050 and the Full HD 1920x1090. When the resolution is higher the images and text will appear smaller. But you can see more text and bigger pictures in the monitor with high resolution.

6. Another thing to note is the 'Refresh rate'. This rate is usually 60Hz, 73Hz, 75Hz, 85Hz. Refresh rate of 85Hz means the picture on the monitor is refreshed 85 times within a second.

7. The brightness and contrast can range between a low 5 000:1 to a high 80 000:1 in a LCD monitor and an average of 5 000 000:1 in a LED, yes that's 5 million to 1 with a LED. This just shows how much better a LED monitor is to a LCD.

8. If you are a gamer then the thing you have to look at with LCD monitors and LED monitors is the response time. If it is 16ms then this is a very bad monitor for gaming and you will experience a ghosting effect in most games and if it is 5ms then you will have an average gaming experience. What you want to get is a 2ms response time monitor, with it you will have the best gaming experience with no ghosting what-so-ever.

In 2004 I bought a monitor Hansol 930 D model, (model no.D19BL, s/n A23490411020263) Since 2011, horizontal image began to narrow, now horizontal image H-size is 210 mm. vertical image size is ...


The horizontal deflection coil is shorted. There is no way to fix that, the entire tube would have to be replaced and that would cost as much as a new monitor.

What is the biggest wide screen monitor can I get to use with the Dimension 2400 and the integrated video?


The monitor (19-inch, non-flat screen, 0.24 dot pitch) presented a more than acceptable image, even at its maximum supported resolution (1600X1200 @ 75Hz). We settled on a more reasonable 1280x1024 @ 85Hz as our preferred setting. According to the documentation, the recommended resolution is 1280x1024 @ 75Hz .Many of the newer LARGE monitors are limited to 60Hz and/or a larger dot pitch...So..look for a low dot pitch(below 0.27) and the ability to run at 1280X1024@75Hz . Passed that, the size is up to you.

Hello, i have an issue where my viewsonic A90F 19" crt moniter's picture dims darker at random...then returns back at random as well. Any idea what it might be? I recommend: | Change Remove Formatting Bold...


If you still have the monitor, check the signal cable -- wiggle it a bit at the PC end and at the monitor end, while watching the image on the monitor. Any change? If you have issues when moving the cable at the PC end, you may want to try shutting down the PC and disconnecting the monitor. Then clean the pins on the monitor's connector with 91%+ isopropyl alcohol and a cotton swab (make sure no cotton is left behind). let dry and try again.

If none of this make any difference, wait for the monitor to go dim. Then, gently smack it on all sides. If the image clears up or changes, there is likely an internal bad connection. Do not open the monitor unless you are familiar with all safety precautions involved.

I have the same monitor and I was having a similar problem. Turned out, there was a cracked solder joint on the signal board at the back of the CRT plus several more questionable ones.
