queries regarding 10 bit / 8 bit

by momipnd / January 9, 2017 11:36 PM PST

I am bit confused regarding the color depth difference between 10 bit and 8 bit LEDs. How can i detect that my LED is 10 bit or 8 bit. The LCDs are with LED backlights.

Why don't you take time to...
by Pepe7 / January 11, 2017 7:00 AM PST

...post the full make/model number? That way we can assist properly instead of providing very general (and arguably, not so useful) info regarding panels overall?

If you pay for 10 bits and get only 8, you paid 25% too much Wink

I'm not sure there's a way other than reading product specs.

On top of that, the source has to have the color depth as well.

Make is Delta and model is 5538. We want to check this is 8 bit or 10 bit. And how we check it is 8 bit or bit.

If I google that I get a flight from Delta airlines. That has no bits at all.
Can you provide a link to the specification and manuals.

To check, compare the difference between a 10-bit source and a 8-bit source. If you see no difference, either it's 8 bits or your eyes aren't good enough to see the difference.
Then repeat with a known 10-bit monitor to see which of that two it is.

Exactly you r right. But the problem is how i can check and verify physically it is 8 bit or 10 bit.

That's easy.

If it doesn't have the new HDMI 2.0 port it's the old line up of 8 bit panels.

At the same website i.e.http://www.deltaww.com/ there is another link which says the model 5588 is 10 bit (1.07Billion) as the link you provided, says it is 8 bit (16.7million). Although, i know the model 5588 is 8 bit but what is the difference between these two links. As the model 5588 does not contain the HDMI port. Any other sign which tells it is 8 bit. One link was that you provided and other one is:
http://www.deltaww.com/filecenter/solutions/download/06/0605/LCD%20Video%20Wall%20Brochure%204-7-14.pdf?CID=0605

See also the model 5580.

This model is 8bit. I want to prove it physically it is 8 bit. Plz help.

Re: physically
by Kees_B Forum moderator / January 23, 2017 12:03 AM PST

Now that's a problem. The input signal is serial (hdmi isn't parallel) digital (a string of consecutive 0's and 1's), the output (the light) is analog. So it's the digital-analog converter that's programmed (either in hardware or in software) to translate 10 bits at the same time in stead of 8 bits.
Only the hardware is physical.

Plz suggest any software or app which translate or differentiatebetween 8bit and 10bit.

Where should that software or app run, and - if not on the monitor itself - how would you like to connect the device it runs on to the monitor you want it to examine.

Its mean there is no way to check it whether it is 10 bit or 8 bit

Without question- you have an 8 bit panel
by Pepe7 / January 23, 2017 7:24 AM PST

And there's no way to magically turn it into a 10 bit one.

To prove it physically
by R. Proffitt Forum moderator / January 23, 2017 9:42 AM PST
In reply to: Re: physically

Will be a challenge. You would need the schematic to see if there is any DAC chip in the design. If it's down in software with PWM then there is NO PHYSICAL DEVICE and therefore you will never prove it.

queries regarding 10 bit / 8 bit

Here’s why 10-bit LCDs will be (and are) cool, and what they mean for the future of TVs.

Nearly all current TVs are “8-bit.” Some may advertise that they’re more, but they’re all inherently 8, as that’s what our TV system is based on.

What this means is the TV is capable of 256 shades of color, for each of the three primary colors: 256 shades of red, 256 shades of green, and 256 shades of blue. (It’s actually a little bit less than 256, but let’s stick with that to make our math easier.)

So with our current TV system, it means there’s a possible 16.8 million colors (256x256x256=16,777,216). That may seem like a lot, but it’s actually not. The human eye can see way more.

About the only way
by R. Proffitt Forum moderator / January 23, 2017 9:46 PM PST

Is from the specs. You asked for a PHYSICAL way to check and without a schematic we can't see if a video DAC is used to see if the bit count.

I can't imagine why this topic is dragging on. Just out of curiosity, can you share what's bugging you?
