Actually, I was happy with my high quality CRT (cathode ray tube) monitor. It was with considerable reluctance that I recently decided to get with the modern era and upgrade to an LCD. It has been quite a learning experience. Looking back, I realize that there are a number of very important practical considerations of which I was unaware in making the change and in making a choice. Perhaps I can pass along a summary of them along with some insight gained by hands-on experience to make the experience a little easier for you than it was for me. You need to do your homework both before and during your investigation. Here are some of the most important things you should know.
An LCD monitor offers considerable advantages in upgrading from a CRT. It is infinitely lighter and takes up much less desk space than a CRT. It uses the smallest fraction of electricity by comparison and is devoid of radiation concerns. When properly installed, its display may prove brighter, sharper and provide superb color.
SIZE: In any size range, an LCD will display more viewable screen than a similarly sized CRT. I decided on a 19 incher, the size of my CRT that I was happy with. Seventeen may work for you if that’s what pleased you on your CRT. Over 19 for average use is both too much screen and excessive cost for most people.
ORIENTATION: Most prefer a normal tall screen (portrait view) for average usage. Wide (landscape) screens are available at greater cost in the same size range and are not recommended unless you have special need for that display. Some makes offer a swivel screen that you can change from tall to wide and back again instantly. You will pay considerably more for this feature when it is available.
COST: Has been decreasing from a few thousand some short years ago to a few hundred today. A quality 17 inch LCD can be found today for under $200, and a 19 incher for less than $300. If you have a watchful eye, special sales are common and offer substantial saving.
BRAND: There is a very significant display quality to be gained in better models of better brands. The most common best quality brands usually topping the review lists in computer publications are LG, NEC, Viewsonic, Dell and Samsung. Different models in the same brand provide different features. Check them out carefully on their respective websites and “Google” for reviews. You need to do your homework both before and during your shopping experiences if you want the best for your buck.
WARRANTY: Better brands provide a 3 year replacement on defective monitors. Don’t settle for a one year warranty!
VIEWING ANGLE: Unlike a CRT, an LCD’s view falls off sharply at the sides when you are not positioned in front of your monitor. In practical usage, this should notbe at all a problem. Your view will be just fine when you are normally seated at your screen, with more than sufficient leeway from the norm.
RESPONSE TIME: Usually indicated in the advertising of better models. A faster response time is better--it indicates how quickly the screen can refresh a video image. If an LCD's response time is too slow, the display's pixels won't be able to keep up with the information sent from the computer's graphics card, and you may see ghosting and digital noise as a result. 8ms or better response time is common on quality LCD’s and is preferred! The lower the response time, the less of a blurring effect is possible on the screen.
ANALOG VS. DIGITAL: Video cards can provide outlets for two different monitor display types, analog and digital. CRT monitors are cabled to your video card with an analog (15 pin) cable. LCD’s usually provide the same cable and connection but will provide a significantly better display when attached via a digital (VDI-D) to a digital port on your video card. Better LCD’s provide both digital and analog connections. So do better video cards. If your card doesn’t have a digital port, you can either replace the card with one that does, or you can add an additional card. Easy to do. Just plug it into a PCI slot and your computer will recognize it. You are really better off in many ways with a better card.
If need be, you can run your LCD with the same analog connection as you used for your CRT previously, but a digital connection will give you better results.
NATIVE RESOLUTION: LCD monitors will provide their best display when run at their “native resolution” which varies with the size of the monitor. For a 19 incher, the native resolution is 1280x1024. The resolution of a display can be changed easily by right-clicking on an empty area of your desktop and selecting “properties,” and “settings.” The same can be accomplished through your Control Panel in your Start Menu. Normally the correct choice will be made automatically by the installation software that accompanies your new monitor.
When you change your most common CRT setting of 1080x760 to 1280x1024, everything, including all your icons and fonts, will suddenly appear much smaller. Your LCD display however will become infinitely sharper. If you find it strange to your eyes, you can easily change your display properties to provide larger fonts. Additionally, many programs like word processors permit you to change your text to any size you wish while maintaining its quality, regardless of screen resolution.
Running at native resolution (your choice to do or not, but very highly recommended) will make your screen display smaller but you will be able to accommodate more viewed area on a page. It may be strange somewhat to your eyes at first, but the greatly increased sharpness and over-all quality of your LCD display will more than make up for it, especially if you are using digital rather than analog display.
AUTO-DISPLAY: Most quality LCD monitors will automatically install at their best display settings when you plug them in. However, they will also provide easy to adjust menu settings for most of their values that permit you to easily adjust the display to what is most pleasing to your eyes. They most common adjustment people make is for brightness. Most LCD monitors tend to be too bright unless adjusted. LCD screen illumination is entirely different and better than that from a CRT.
RUNNING MULTIPLE MONITORS: What’s to do with your CRT now that you have your new LCD? One of your choices may be to keep it and run two monitors side-by-side. If you are using Windows XP and you have two ports on your video card (or two video cards), it’s easy to do with a few simple settings in your display properties menu. You will then be able to run two different programs at the same time and easily drag items from one monitor screen to the other. Your cursor will readily mouse from one monitor to the other alongside. It can double your productivity and allow you to see and do things you did not know were possible.
Over all, upgrading to an LCD monitor will greatly enhance your computer experience and enjoyment. It’s way more than worth any effort or expense involved.
