I understand "unique colors" ... I don't understand what that means in a discernible difference to the human eye ...

Richer colors? More detail? More contrast between dark and light? Marketing gimmick?

899 - -480h X 800 = 384,000 total pixels
HELIX 7 - 480h X 800v = 384,000 total pixels

What is 16bit vs 8bit when the total pixels is the same ?? (pixels per square inch maybe?) ...

MFD screens, TV's, phones, computer monitors ...Published display properties are written in Greek to the layman ...

Even I need layman's terms sometimes ...

Your monitor can likely only select 256 colors or 32 bit colors now a days.
The old Win95 days you only had 256 color available when you started a fresh W05 install which looked horrible, then 16 bit was available after the drivers were installed.

Richer colors,more detail, more contrast between dark and light. No gimmick....

https://en.wikipedia.org/wiki/Color_depth

My point exactly ...

Every word in that wiki (except the, but, and or) is un-intelligible to the layman ...and what it may possibly mean to the images a user is seeing in a Sonar display ...

Multi-million pixel smartphone displays = maybe relevant ...

Low-resolution (relatively) Sonar displays = I highly doubt it's relevance to the human eye ...

I guess if you're completely unfamiliar with some of the base level computer terms, it's no help to you.
You would need to read up on the basic terms used.
I have been repairing, building & using PCs for a while, so much of it does make sense to me.
Otherwise unless you can use a PC and shift the displayed colors from 4 - 8 - 16 -32 bit colors, you'll just have to trust that it gives you richer colors,more detail, more contrast between dark and light.
All in all, a better user experience.

UNCLE!

As is with 99% of Sonar display users ...

If we could just use that same key-press sequence on a Sonar display - it might actually be a determining factor in understanding published Sonar display specs for that same 99% of Sonar display users ...

Dang ... My OCD is rampant sometimes ...

Hence the closing term UNCLE...


SOMETIMES?



Unless people take the time to learn about something on their own, they are destined to say "I am clueless"...
I prefer to learn what I can, when I can.

A few options from amazon. The only one with KVD on it that was cheaper is the helix 5/SI. All you get for the extra money typically is the fact it says KVD. Same functions otherwise.They do have the Helix 5 and 7 with gps, without SI or DI. check it out. Amazon.com. Free shipping.
