Well I was told by a friend that he heard the optimum color temperature for gaming is 9500K as opposed to 6500K for everything else. Can anyone confirm this? He sent out some emails to find out and has not received a response yet.

Do TV's have the ability to adjust the color temperature within the user menu?

In the menu of my CRT computer monitor, you can either select 6500K or 9300K for the color temperature. 9300K is the default, and I have never changed it before. I just realized that there were 2 settings and I decided to toggle between the two. I found that 9300K was much better looking than 6500K. With 6500K the whites were not white and the whole screen had like a yellowish tint, and it just looked very drab. Then I switched back over to 9300K and it just livened and brightened everything up. Why is this? I thought that 6500K was the standard for everything.

use search .... this exact question was just covered (in fact maybe it was your friend that asked!). Feel free to bring up anything new you have to add to the previous thread.

Yes I'm aware of that. I thought you were saying there was a different one.

If your question is what is the difference - try this trick

You already stared at a white field - then switched from 9300K to 6500K. You saw a yellow field that was dimmer.

Stare at it for a while. Your brain WILL be convinced it is white. Switch back to 9300K. Now you will realize that 9300K is bright blue not white.

After you try that and see the difference - then we can talk about why the settings are there if you indeed adapt to the white point.

If you want to have even more fun with the brains chromatic adaptation - get the THX blue glasses used for the DVD test patterns and wear them around for a while - then take them off.

So why is 9300K the default? Is that what it is supposed to be at?

It's also amusing to wear sunglasses with a very slight amber tint, remove them, and revel in the blueness!

The First Clarke Law states, 'If an elderly but distinguished scientist says that something is possible he is almost certainly right, but if he says that it is impossible he is very probably wrong.'

From your other thread:

D5000K is the ISO world standard for digital graphics industries. D6500K is the world standard for color video. The THX Games program specifies D6500K for the monitor white point and ambient lighting in electronic game production facilities. Game producers who care about image quality will adhere to this standard. Most computer monitors and TVs will offer a color temperature setting for "6500K."

Displays, including computer monitors, are set at higher(cooler) color temperatures to MOVE THEM on the sales floor. BRIGHT displays sell - Dim displays smell. It's all about selling displays & TVs!

'nuff said.

At the end of the day, if the graphics for any given game were created on displays with 9300 degree colour temps, then they really won't look the same with any other colour temp. But aside from the aforementioned THX spec, you'll never find this info published anywhere.

I'm interested to know why the color temp should always be 6500K. I used to think it should be set to match the ambient light in the room, and even calibrated some of my sets with a white sheet of paper, just making white on the screen match that. lol

Because that's the standard. That's how the content was produced. Otherwise, the colors you are looking at are inaccurate.

Thinking about it more I understand it. A different color temp would make it as though you were looking through tinted glass.

I use Daylight fluorescents, so I likely got it right anyways. :rolleyes:
