LED Monitor Features and Connections (Ports)

When you take a look at the names of LED monitorsfrom the name you will recognize panel type and what kind of coating was used in production. We have covered that in previous sections. Now, when shopping for an LED monitor you will find yourself looking at all kinds of specifications, additional features, and connections. Now I will list what you need to understand, so pay close attention.

I will start with connections. LED monitors are typically produced with few different connections for connection with your PC or console. Most common connections or ports are:


– D-Sub



– Audio In/Out

– Speaker

Important Note: for connecting HDMI devices pay attention to the HDMI rating of your monitor. For example, HDMI 1.2 supports up to 1080p resolution, HDMI 1.3 support up to 1600p. For 4K resolution, you need monitor with HDMI 2.0 port. Display port 1.2 and newer supports 4K resolution.

When searching for an LED monitor, if you want to make sure that you have bought the right one for your money – you need to pay attention to the following features and specifications. Once you know what you need, you will know exactly what to look for. Most common features or specifications:

– Panel Size – panel size is measured from corner to corner (diagonally). We have 19, 21, 25, 27-inch monitors, etc.

– Aspect Ratio – Ratio of the image in relation to the height vs width of the monitor. Most common aspects are 4:3 and 16:9

– Response Time – time needed for a pixel to change color from white to black and white again. Effectively, the time needed for a pixel to change color from one to another.

– Contrast Ration – the difference between the brightest white and the darkest black. Look for static contrast at least 1000:1.

Brightness – brightest white that can be displayed measured in cd/m2.

– Viewing Angles – typically displayed as 170/160 (170 degrees horizontal, 160-degree vertical viewing). IPS has the best viewing angle offering 178/178 degrees.

– Refresh Rate – typically between 60-75 Hz, modern monitors with 120Hz. Even if your panel is more than 60Hz, if you connect it to DVI it will be capped at 60Hz.

– Color Depth – how many colors it can produce, most common is 16.2 million colors (8-bit), 1.07 billion (10-bit) monitors.

– Pixel Pitch – the distance between pixels. Tighter pixels produce a sharper image.
