A standard 4K monitor is packed with a ton of pixels that give clear crisp images. A 4K monitor has a resolution of 3840×2160, which is about 8.3 megapixels. This is approximately double the resolution of a typical HD monitor. The conventional HD monitor has about 2.1 megapixels that give a resolution of 1920X1080. This is why a 4K monitor is able to give a much sharper screen image when all other factors are held constant. The high resolution provides users with capabilities to edit 4K content and 8MP images in their native resolutions without the need to scale them. This is particularly useful for experts and professionals who need to maintain quality and accurate work. This feature gives creative designers an opportunity to come up with master pieces. For everyday computing use like watching movies and working on office applications, powering a 4K monitor is never a big issue.
When connecting a 4K monitor for use, enjoying its full 4K definition needs a quality cable that meets the set standards. It is important to note that some cables have wiring that is not properly configured.. These are cables that are not certified and their use may cause all sort of unpredictable and weird display behavior. In most uncertified cables, pin 20 is connected. This causes voltage to be back-fed into the PC system. The outcome of these unwanted voltages is that the mice or keyboard may light up when the system is off, the video and display randomly go out of synch and the PC becomes generally unstable. The uncertified cables may also not provide the required bandwidth to run the display at the full 60Hz needed by a 4K monitor. The user is then forced to change settings to lower the refresh rate. When the PC system using the 4K monitor displays any of these issues, to resolve the issue first replace the display port cable with a display port certified cable.
The HDMI standard is complicated and need some insight when using it with 4K monitors. Most 4k monitors support HDMI. The challenge is when it comes to graphic cards that support the HDMI 1.4 standard. The HDMI 1.4 locks the 4K output at a meager 30Hz. To get the required 60Hz at 4K, the HDMI 2.0 specification is needed. This can only be implemented if both the monitor and the graphic card support it. Presently, the HDMI 2.0 is supported by Nvidia’s 900 series graphics card. With this HDMI limitation in mind, it is generally easier to drive a 4K monitor using a display port connection than HDMI 2.0 cable.
The final consideration to make is the Dots per Inch scaling within windows. Icons and texts can look incredibly smaller when 100% scaling is used with 4K monitors. This is because the pixels are closely packed together giving a very high pixel density. One way to go around this huddle is to increase the DPI scaling in windows. This will make windows and menus more visible. It is worth noting not all applications scale properly. Some may become blurry or just not render its elements as expected. Microsoft has tried to correct these flaws and also push application developers to do the same but still flaws remain. The rule of thumb is to make do research and be sure the applications you are to run do scale properly.
