LCD vs. CRT Monitor Comparison

Text and images (scans of census records) are crisper and sharper and the LCD monitor is easier on your eyes. Monitor's size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk. It is also heavy.

However, LCD monitors have thin flat screen. Therefore occupies very less space and is lighter than the CRT monitor. LCD monitors can be fixed even on wall. Display Size: Even though the display size of a CRT monitor is calculated diagonally, the actual display size is smaller. For instance a 17" CRT monitor will actually have a display size of only 16" However, the display size of 17" LCD monitor will have 17" display size. Resolution: CRT monitors can show different resolutions. The resolution can be changed as required. LCD Monitors will have Native Resolution and therefore has a fixed resolution. The best resolution will be the native resolution for that LCD monitor. Viewing Direction: A CRT screen can be viewed from all directions. And from different distance. But LCD monitors cannot be viewed from all directions. LCD monitors can only be viewed straight. Therefore its viewing direction is limited. If viewed from other directions the colors will change and sometimes the vision will be unclear if not viewed straight. But in recent years the new LCD monitors have improved on this defect. Radiation Emission: The radiation emission in CRT monitors are higher. This will not be visible normally but it will affect eyesight and may cause head ache. Long term use of these monitors may even affect the eyes adversely. LCD monitors do not have this type of Radiation emission. Therefore LCD monitors are good for the eyes. Price: CRT monitors are priced very cheap. However they consume more power. LCD monitors are priced higher, but they consume less electricity. Though the electricity consumption is not very significant for personal use, it is very cost efficient in big organizations with many computers.

LCD Monitor
Text and images (scans of census records) are crisper and sharper and the LCD monitor is easier on your eyes. Dot pitch: This is the space between dots and is measured in fractions of a millimeter, e.g., .25mm. The smaller the number the better because the dots are tighter. Many manufacturers don%u2019t even list the dot pitch anymore and you probably won%u2019t be able to tell the difference between a .22 and .27 pitch anyway. So, if you like the monitor then don%u2019t worry about the dot pitch. Passive-matrix vs. active-matrix: Do not buy a passive-matrix monitor. I seriously doubt you%u2019ll even see one for sale, but%u2026just in case. Having said that, there are some new passive-matrix technologies that are worth buying. If the monitor isn't TFT (a type of active-matrix), look for CSTN or DSTN (the latest passive technologies). Brightness: How bright is the picture, expressed as cd/m (I have no idea what the units mean). Look for a brightness level of 200 cd/m or greater. Again, if the monitor specs don%u2019t list this value (not all do) be sure you can get your money back. If the lighting in your office (kitchen table) is subdued the brightness factor won%u2019t be as important as if you have a lot of sunlight streaming in. Don%u2019t pay extra for extra brightness unless you%u2019re worried about bright sunlight. Overall, the contrast ratio will have a bigger impact on picture quality.

CRT
Speaking of easy on your eyes, there isn't any glare, and the flat screen means no distortion. By the way, even those expensive old-fashioned flat screen CRT monitors have some distortion.

Hard Drive Failure: Logical and Physical Symptoms and Cure

Media failure has two ways to go through: logical and physical.
To differentiate, this is required to have a proper guideline so as to determine which case is data recovery service candidate and which one will get resolved easily through data recovery software.

Data recovery industry offers you a set of commercial products, which say the words of data recovery as a result of some simple clicks, while, data recovery people are also standing to give you a manual help. All these comprise to make either the user itself or the expert technicians to access all the lost data. But the problem arises, when the user can’t discriminate between the cases.

So first check it out, whether the hard drive is functioning or not. Try booting it from some another media such as CD or another hard drive which is fit and fine. A physically well hard drive is recognizable in CMOS, so can be booted. However, in case if you get some errors and hard drive fails to boot, using any of the trick, then problem is lying with the internals and so only data recovery service is a solution. But remember to stop there only, when you get an indication that hard drive has got physically damaged as damage could become more serious with the attempts.

After determination, then comes the solution. Use data recovery software, if you find the drive bootable. However the data recovery success may vary with the application, but the basic criterion is the same which is scanning the hard drive and dealing with the file system. As the progress of scanning moves on, the intended meter shows you the same and within some time, you see the data recovery results enlisted.

But before any use, be sure to read the instruction manual of data recovery software manual carefully. This will enlist all the requirements and stepwise guide to data recovery. For all of them one common thing is never to install the software on the affected hard drive as this will overwrite the recoverable data and make the likelihood of data recovery to low.

On the other hand, if you get the sign of physical problems, don’t ever dare to use the software utilities. If you get some unusual sounds, no doubt, the problem is harsh. But making the correct decision of turning off the system will save the major data.

Data recovery people daily receive lots of hard drive, affected from the physical mishaps. They, then, examine it thoroughly and predict data recovery chances and quotes for the same. Upon the approval of customer, the process begins with the determined tools and procedures.

There is a bunch of data recovery companies offering the data recovery part. Some of them may be the unique combination of both help and hence are considered to be complete and ultimate.

Stellar Information Systems Limited provides you data recovery solutions which have great power to bring results. Data recovery software for different operating systems scan the hard drive and recover all which has got lost due to logical problems. Also, the data recovery service is absolute cure with Class 100 Clean Rooms and expert technicians.

Troubleshooting for Resetting Your Hp, Dell, Lexmark, Brother or Samsung Printers

Ever faced problems with resetting your printer? Well, here we provide you invaluable tips to help you troubleshoot your HP, Dell, Lexmark, Brother or Samsung Printers in easy steps.

Resetting an HP laser printer

There is a technique known as cold resetting. It basically will set all your HP printer settings to the factory default levels. It is important to note that any settings made at the control panel of your printer are going to be reset. Hence, in case you happen to have a JetDirect card then even the IP address will be reset to the factory defaults. You can try to reset NVRAM. To do this, switch off your HP printer and then hold down the ‘Go’ key for around 20 seconds while switching the printer back on again.

- HP 1200 and 1100 models resetting: To do this, simply change the data by going into the service mode. This is applicable if your HP printer has a display panel. Otherwise you need to hold down the ‘Go’ button for around 5 seconds while the printer is switched on.

- HP 2100 printer resetting: You need to press the ‘job cancel’ key after switching off the printer. Then switch the printer on and only then release the key called ‘job cancel.’

- HP 2200 printer resetting: Switch off your printer and then hold down the ‘Go’ key. Switch back the printer on while holding the ‘Go’ button till the light comes on. Then release the button.

- HP 6P and 5P models resetting: Switch off your printer and then press the ‘reset’ button and within 20 seconds switch on the printer back again.

Resetting a Dell printer
You can reset your Dell printer fairly easily by simply double-clicking on the ‘Reset Dell Printer’ icon. You can reach this icon by clicking on the folder ‘UAN’, then clicking on ‘System Utilities’ and you should find the icon. However, one word of caution – this method will function only if the USB cable has been directly connected from the PC to the printer.

Resetting a Lexmark printer
You will firstly need to switch off your printer. Then simultaneously press the RETURN and READY keys while switching the printer on. This will take you to the Diagnostics Mode. The display unit will show the message ‘Performing self test’. Choose ‘Maintenance count’. Reset the count to make it zero. Then select the RETURN key and go back Diagnostics Mode. Then you can reset the printer to go back to the normal mode.

Resetting Brother Printer
You need to keep pressing the DOWN or UP keys a couple of times till you see ‘Maintenance 99’ displayed on the display. Then hold down the ‘Set’ button to go to standby mode. Please note that if you press the exit key only after typing in a single digit then the machine goes to maintenance mode in initial stages.

Resetting Samsung printer
You need to press the following keys in quick succession – MENU # 1 9 3 4. Then you should see a message on your display saying ‘TECH.’ Then again select the MENU key followed by ENTER. The display will now show ‘TECH MODE.’ Then select the ‘<’ key two times. Your operator panel should show ‘NEW CARTRIDGE’. Then select ENTER. Now the panel will show [YES]. Select ENTER key again. You can exit from this mode by pressing MENU # 1 9 3 4 again one after anotherCredit: James Kara Murat
