If you are still not on the flat-panel monitor bandwagon, you have got to be considering doing it soon. And, if not, then you should! It’s the trendiest peripheral to own. It represents power, fashion and all things young and happening. Until you replace your CRT screen you wouldn’t notice how much you detested that monstrosity! But before you spend your hard earned money, getting to know the object of desire will do you wonders.
Buying guidelines:
1. Flat panel monitors use interfaces - analog or digital. The most up-to-date models have digital interface but an all-digital configuration costs a good deal more. If you are purchasing an analog flat panel, you should attach it with a digital interface to your video card with a digital out jack to mainstream the signal.
If you are thinking about to buy a digital interface, you need to investigate its compatibility. There are several digital interface standards available today-Plug and Display (P&D) from the Video Electronics Standards Association (VESA), Digital Flat Panel (DFP) from the Digital Flat Panel Working Group, and Digital Video Interface (DVI) from the Digital Display Working Group (DDWG).
The P&D interface is the oldest of the three criteria and chances are your new model wont have this convention. Support for DFP standard is seen across many hardware vendors. The DVI standard is the newer and the most popular. Do your research and whichever standard you chose, you need to match its ingredients that consist of cables and video cards!
1. Pixel-refresh response time: In a LCD monitor, the time required to switch from light to dark objects or vice versa, is referred to as Pixel-refresh response time. If the response time is poor (more than 40ms), you may see ghosting effect, i.e., the image seems to remain longer on the screen than it actually is!
Whereas in a text environment this would hardly matter, in a gaming or media centric environment the effect could be a deterrent. More inexpensive models give more ghosting than their costly counterparts. Also, pixel-refresh response time is not articulated on the monitors. You need to watch in detail to judge the performance of each model.
1. Viewing angle: One trouble with a flat panel monitor is its viewing angle. Laptop users must have experienced this problem. Moving away from the monitor in any direction causes the display to appear black! Various models offer different viewing angles horizontally and vertically.
Find the one better suited to your discretionary income! In any case, for a home PC, the viewing angle doesn’t make much difference but if the monitor is going to be used for official presentations then it should have viewing angle of at least 120 degrees horizontal and 100 degrees vertical. Also, ask for add-ons like pivoting frames.
1. Size: bigger is better, but with flat panel, remember 15-inch screen gives you the experience of a 17-inch CRT monitor. If you can shell out for 17-inch flat panel, by all means, go for it, if not, a 15-inch screen should not be a disappointment.
Other things to check when buying a flat panel are guarantees and warranties. A three-year warranty is recommended. People change the monitor settings in stores and while purchasing; make sure that you analyze the piece adequately. You now have the basic information; all you need is time to check out the market!

If you think that electronic repair is very difficult to learn then you have to read this article where only by using a solder gun could solve a Monitor color problem. Of course there were many tough dog cases (very difficult to find out the fault) in electronic repair but at the same time there were also many cases that can be solve by some simple ways. This LG 710E LG Monitor came in with no blue color problem. How do I know if the blue color was missing? Simply run a color test (that you may also download from the internet) or from a Monitor testing program generator, you could clearly see as which of the color is missing when you run the color bar test.
A missing blue color in the Monitor could cause the display to turn yellowish. Troubleshooting color problem is one of the easiest in Monitor repairing. Whether the missing color is from blue, red or green there are some areas that you need to check in order to successfully repair it. Here are some of the points that you need to check:
- A bended color pin at the VGA connector. (If pin one is bend then there would be no red color)
- A defective VGA signal cable. If the internal wires were broken then there would be missing colors. You can check if the signal cable is good or bad by doing a continuity test using a millimeter.
- Dry joints in the CRT board such as in the CRT socket pins, video pre amp and driver IC and even at the connector pins. In fact this problem contributed about 80% of Monitor color problems. Applying fresh solder would usually solve the color problem.
- A defective IC either in the Video Pre-amp or Video Driver IC.
- Faulty components in the CRT board. It could be a shorted driver transistor or even electrolytic capacitors that the ESR reading had shot up!
- A bad CRT socket. Sometimes decayed glue could cause the internal pins rusted and thus affecting the colors. Replacing only the CRT socket would definitely solve the problem.
- A weak or a defective picture tube (CRT tube). Yes, I do came across one of the electron gun (most probably the cathode materials had used up) in the tube faulty caused a missing color in the screen. There’s no way to repair this type of problem-the only way is to replace the CRT tube.
- In the newer type of Monitor, color setting is saving in the EEPROM IC. Thus, if the EEprom data is corrupted, you would also get a missing color! The only way to repair it is to reprogram the IC or use a soft jig to tune it back the color setting.
Now, which one of the above is the easiest to start with first when comes to troubleshooting the color problem? I believe you would agree with me that the first, second and the third are the easiest compare to the rest. Normally I would hit the Monitor with my bare hands to see if there are any changes in color at the display (be careful not to hit too hard till the casing broken). If there is a change or flashes then I can say that the Monitor has dry joints. And if it stills the same no matter how many times I hit it, I will then starts check the VGA connector and the cable.
In the above Monitor, the problem was dry joints because when I softly hit it with my hand at the side of the Monitor, the blue color immediately appears. The aluminum shielding at the CRT board was opened and I could clearly see lots of dry joints especially in the video pre amplifier and the video driver IC. When you resolved please don’t just touch on the IC’s only, you need to resolved others area as well like the CRT socket pins. Doing this would prevent any color loss again in the future. A good job would prevent call back and to save you time and money and most of all your reputation!
After everything was done, you then need to gently knock at the CRT board again with the plastic handle of the screw driver to see if the color problem still exists. You may also knock on the main board just in case there is any dry joint there. One more thing, if you find that the Monitor is a bit dusty, you may use a vacuum cleaner and a brush to clean up the dirty area. Whether you are repairing the LG 710E or any other brand of Monitors, if you come across any monitor color problem, you can always use the procedure above to find out the fault. If the VGA signal cable is okay and there were no dry joints in the Monitor, I guess the only way is to use voltage testing method and start checking components with your tester or meter.

A flat panel monitor is really not essential for most computer applications, because, well frankly, any old monitor will do. All your really need from your computer monitor is the resolution to word process, honestly, unless you are some kind of super gamer, or perhaps an artist or graphics engineer. However, a flat panel monitor can be nice and make your computering experience more pleasant by far. First of all, it takes up much less power than a normal monitor, (also known as a crt monitor) so a flat panel monitor can greatly improve your computering experience by decreasing your electric power consumption.
Second of all, there is a subtle distortion provided by normal crt monitors which you don’t get with flat panel monitors. Your normal old standby crt monitor has a curved screen, and although your mind has been carefully trained to edit it out through hours and hours of fixedly staring at the computer screen, nonetheless, it does cause eyestrain which can be avoided with a flat panel monitor. You won’t really understand the difference until you try a flat panel monitor, so I suggest just trying it - your eyes will thank you, and then you will have to track me down and thank me. A flat panel monitor just has a clearer image, and that is that. It doesn’t distort, and besides that, the colors are more even and there isn’t the flicker of a normal monitor. You are trained to edit out the flicker too, but believe me. It is there, and you will notice the absence of it when looking at your beautiful new monitor.
Also, since so many people look at movies on their computer, if you are one of them, (and I know I am), it absolutely makes sense to buy a flat panel monitor. It just makes the image prettier, and the experience more enjoyable. Especially with the lights out, any distortion can cause vertigo and discomfort, so for your own viewing enjoyment, how can you go without a flat panel monitor. Another reason for a flat panel monitor, although probably not the biggest reason for most of us, is that it saves space. It lacks the size of a normal monitor - not only the screen, but also the body of a flat panel monitor is flat. This means you can fit it in a smaller space, or can have more room on your desk for other things such as books or amusing office executive toys such as wheels that spin up and down ramps indefinitely.

If you’re in the market for another monitor, you really need to consider a flat screen. These cool devices take up a whole lot less desk space and actually are a whole lot nicer to look at as well. Those old boxy monitors are a thing of the past. Not only do the flat screen monitors take up less space, but they’re actually not as expensive as they used to be. You can easily get one for $200 or less. That price is amazing considering what they used to be just a couple years back. Flat screen monitors are now within the reach of everyone!
This is one sleek looking LCD wide-screen monitor. LG has really put out an excellent product. One customer has said it is the best they have had. It even offers more clarity and brightness then an HDTV.
To cover the basics this monitor is certified for Windows Vista and the monitors design is intended to compliment the new OS. This monitor offers a 1440 x 900 screen resolution along with 16:10 aspect ratio designed to offer you a better view of the screen. For those that do not know what aspect ratio is–it is just the width of the screen divided by the height.
One of LG’s personal technologies is the FLATRON F-ENGINE. What is that you ask? Well, it is a picture enhancing computer chip that delivers you with amazing color, superb contract and image quality. This is what makes the monitor so good. The FLATRON F-ENGINE is able to balance the contrast and brightness both independently as needed to again keep the image supper for you. When it comes to response time for the monitor you have been used to times like 25 ms or maybe 16ms. That is milliseconds but the higher the number the less crisp and clear your picture. Now LG has really set a new level of excellence here by providing you with a 2ms response time. This delivers you a very crisp and clear picture or image.
Another way that this screen provides you with excellent qualities is by offering you with a 170 degree viewing angle. This means that even at up to 170 degrees from the center of the screen you can see it very well. This means that when you are showing someone something on your monitor they do not have to sit right next to you in order to see the screen. You can both have a little breathing room while viewing the screen clearly. How much room with this great monitor take up? With the stand the monitor measures 20.1 inches x 16.7 inches x 6 inches. That sure is a lot smaller then those old box monitors that weighted a ton. Speaking of weight, this LG monitor weight in at just 7.9 pounds–much better then the old days.
Of course the box will include the monitor and the all the basic cords to connect to power and the computer. In addition the monitor comes with a 3 year warranty that covers labor.
This monitor will give you exceptional value for your money and deliver you great graphics. You can find these monitors from $230 or less depending where you shop.

Flat panel computer monitors are all the rage these days. We live in an overcrowded world and anything that saves space is a great thing. In fact, many of the newer computer desks are set up to take these monitors into consideration. It won’t be long before the flat panel computer monitors are the standard.
In the meantime, those of us with the clunky old huge monitors can look at those with the sleeker slimmer flat panel computer monitors with envy. If you haven’t seen one you should really check them out. They come in many sizes and with many different price ranges. Depending on what you use your computer for, you may find that you can do quite well with one of the lower end flat panel computer monitors. If you use a lot of high-end graphics intensive functions on your computer you will want one of the better quality (and more expensive flat panel computer monitors). These flat panel monitors not only save space, but they are much more environmentally friendly. Less parts to get rid of once they need replacing, this means they take up less space in landfills. They consume less energy and they have fewer emissions than traditional CRT monitors. These small favors add up when you consider how many households worldwide own computers.
Not only are these monitors more environmentally friendly, they are also work place friendly. They are easier on the eyes of workers and free up desk space to allow for more productivity in smaller spaces. With larger companies paying a premium for office space every little thing that results in needing less space is a good thing for overhead expenses, not to mention anything that can increase productivity.
Flat panel computer monitors offer many benefits to the average consumer. Check them out and see if one of these might be well on its way to your wish list.
