Do you need a graphics card for your laptop?

The graphic card is an essential component of PC and laptop, as it provides better display and picture output. It is a plug-in device that enhances the available display features. It connects to the motherboard via PCI/AGP slots. Without adding an external graphic card, the system would utilize the inbuilt video display drivers for display optimization.

Purpose of Graphic cards

The basic and primary function of a graphics card is to obtain video information from laptop processor and convert them into electronic signals. The monitor, in turn, receives them and decodes it into quality pictures that can be displayed. The minimum configuration of graphic card required for any laptop is usually built into the motherboard. However, this can provide just the basic display features.

The graphic cards come with their own set of memory called VRAM. The card utilizes this for handling video information. This reduces the utilization of laptop’s RAM and hence enables the machine to perform faster.

Adding graphics card to your laptop

The chances of requiring a graphic card upgrade for your laptop is pretty slim these days. The reason is obvious. The majority of today’s laptops come equipped with GPU [Graphical processing Unit]. The GPU is attached to the laptop motherboard, so upgrading a graphic card would mean replacing the entire motherboard. It’s as good as buying a new laptop.

The viable alternative would be to include external graphic card through the USB port. However, this cannot be used for gaming purposes which require extreme quality graphics. By plugging in an external graphic card through USB port, one can make use of either built in screen or an external display like monitor or HDMI.

Brand dependency

The possibility to upgrade the graphic card in a laptop also depends on the brand and model of the laptop in question. Certain laptop models provide the updating option. However, majority of laptop devices in the market are NOT upgradable.
