There’s no standard format for a spec sheet, so comparing different monitors from different companies can become a bit confusing or frustrating. In this YouTube Video, Green Marine Monitors aimed to show the 7 elements one can find on different spec sheets to help determine which marine display would be the best. Below is a summary of each point from the video.
- Dimensions
Make sure you read the ‘mechanical’ dimensions and not just the ‘active display’ dimensions when determining if the monitor will fit in the console of your bridge.
- Signal Inputs
If you want to customize your electronics package, make sure you have all the signal inputs you need for radar, cameras, and more.
- Brightness
Sunlight readable monitors should have a brightness of 1000 nits, or 500 nits possibly with “bonding” technology. Also, make sure the monitor can dim to black and 1 nit or less for better nighttime viewing.
- Contrast
Contrast is what adds clarity to the display and should increase when the brightness increase if it works properly. At least a 500:1 contrast ratio is necessary for quality viewing.
- Viewing Angle
Make sure the viewing angle in the specs lines up with the angle of your console. You can measure the angle pretty easily with an app for your smart phone.
- Waterproof
Marine monitors should have an ingress rating of at least IP65, and you’ll need to read further to see if the monitor is waterproof from the back for pedestal mounted monitors.
- Power
Finally, ensure that the marine display uses a DC marine grade power supply with a secure connector that won’t loosen when the seas get rough.
