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.

Neovo x17a monitor


Are the settings on the video output correct? Is there a green or orange light illuminated. There is a difference between the Power LED and the Signal LED which is green. If you have no signal the LED will remain orange or yellow but not green. If the LED is green, then a signal is getting from the PC but not necessarily good. Check the signal with another monitor or TV if you can. Check the cable.

Konica Minolta Dimage 7 delay in start up and shot down procedure Hi, I have a Minolta Dimage 7 Digital Camera SN91202050. I'm very keen in electronics and I have its service manual (45 pages). Few months ago, I upgraded the firmware to ver 2.01e. (I read the full compatebility notice before installing). The camera worked so fine. I've got about 2000 jpgs And the last day I took about 200 jpgs in a very short period of time. So I was enforced to exchange the batteries during the snapshots. I'm using 2500mAh MiMH Kodak batteries. I noticed that the grey front right hand part of the camera is a little bit overheated. The next day, and after the camera returned to its normal temperature, I tried turning the Main Switch/ Mode Dial from OFF to Recording Mode, after putting a completely charged batteries. Unfortunately, I heard a small sound "Tick" then nothing happened else, the Data panel stayed dim(unlit) and with no data, and no red indicator had seen, also the monitor LCD didn't start. I didn't hear the noises which the camera should give in normal conditions. I left the switch as is, few minutes later, the camera continued the startup procedure, as I heard the noises and the Data panel lit in green and it displayed the normal status. I made several snapshots and everything were going well. I turned the **** to playback mode, I have seen the entire snapshots I did. Which mean tha the CF card is working well. Also all the other knobs were working properly. Then I decided to turn the camera OFF. Again, the LCD monitor turned OFF directly, but the upper Data Panel was left ON!!! And I heard "tick" Few minutes later, it turned OFF automatically. And I heard the same noises in the normal manner. 1-Does that mean the main board had a cold welding point? Or, the board was affected in the earlier overheating. I tried to use the transformer instead of the internal batteries, and I found this same situation. Delay in the turn on and turn off. And also the delay period is the same. 2-Does that mean that some chemical capacitors were damaged? ( wich capacitor should I replace?). 3- Does that mean there is a cold welding in some points beyond the processor in the MAIN PCB ASSY(0402) due to the frequent humidity and overheating? N.B I tested the internal backup battery, and it gave 3.24V (it's ok) Kind Regards, Soubhi Sabbagh Email: s.sabagh@aloola.sy
