DVD Player and writing software
To play a DVD film on your new DVD Rom or DVD-RW you require software to do this. Many of our drives are sold as bare drives (see above) and do not come with a DVD film player. We have found a FREE player you can download for your new drive, o write with a CD or DVD to help get you started try some free software from the link below.

LCD Monitors and Manufacturers Dead Pixel Policy 
Please be aware that the monitor companies do not class a less than FIVE dead pixels to be a fault. See below for the policy of the manufacturer warranty companies in general. You may contact your warranty company but be aware that they may tell you the same thing that is the monitor is not classed as faulty.

Dead pixels

TFT monitors suffer from a phenomenon known as dead pixels or dead sub-pixels (a sub pixel is one of the red, green or blue dots that make up a pixel cluster) in which they do not function. Due to what an LCD monitor is a dead pixel or two is so likely they are not considered to make a monitor a faulty item and there are certain rules laid down (ISO 13406-2) setting out how many dead pixels there need to be before you can return your monitor. A dead pixel can show it's self up in two ways. Cheaper monitors will show dead pixels as tiny white dots as an LC D's pixel's natural state is to allow light to pass through it. A higher quality TFT monitor will be clever enough to ensure a dead pixel stays black which is much less annoying and noticeable.

ISO 13406-2 gives 4 quality levels. Type 1 dead pixels are always lit (white). Type 2 are never lit (black). Type 3 can be anything else eg a dead sub-pixel. Type 4 concerns the total number of faults in a certain screen area.

If a monitor says it's a Class 1 monitor of the ISO 13406-2 standard then there will not be 1 dead pixel or sub-pixel within the display upon delivery. If there are you can send it back for a replacement. There are very few manufacturers willing to claim class 1 compliance (in fact at time of writing there is only 1 such manufacturer known to the author). Class 2 compliance is everything else. Most monitor manufacturers comply with class 2 although they are unlikely to admit to this on the box! This could mean that every pixel on the panel is dead, however, they have all agreed that there will be no more than 5 dead pixels. Well, not quite. The larger the panel is the more scope for dead pixels there is and resistance will increase from manufacturers to replace a monitor. It's unlikely any class 2 compliant TFT manufacturer will replace a 17" panel with 6 dead pixels on it, for example.

In with the cost of items are many factors, our warehouse and shipping costs include, booking goods in, storage, wages, paperwork, picking, checking, packing, wrapping, labelling and then input of data and all the materials (not just on the packet) for shipping and then your delivery cost.

Why is my hard drive showing smaller than its stated size?

Hard Drive manufacturers in general, define a gigabyte (abbreviated as GB) as 1 billion bytes (1,000,000,000 bytes).

Operating Systems and software utilities define a gigabyte as 1,073,741,824 bytes, which is based on an earlier way of measuring hard drive capacity. This method measures a kilobyte as 1,024 bytes rather than 1,000.

In like manner a megabyte is reported as having 1,024 X 1,024 bytes (1,048,576 bytes) rather than 1,000,000 bytes and a gigabyte as having 1,073,741,824 bytes.

A kilobyte is 1000 bytes to person counting in decimal and 1024 bytes to a person using the binary representations. The only thing common to the two measurement systems is the size of a byte.

Your operating system uses both binary and decimal representations of hard drive space depending on where you look. Hard drive manufacturers use the decimal representation, from this you can see how many bytes the drive will hold after a quick glance. If you use the binary representation, you have to do a calculation to figure the exact number of bytes your hard drive will hold.

Let’s use the example of an 80 gigabyte hard drive. A 80 gig would be defined by the hard drive manufacturer as 80,000,000,000 bytes, but Windows will report that as 74.5GB in some places. If we calculate 80,000,000,000/1,073,741,824 we get roughly 74.5 (binary) gigabytes. A 160 GB drive would be 160,000,000,000/1,073,741,824 or 149.0116119 (binary) gigabytes.
