i'm trying to decide what the best color temp is for my Mitsubisht 55" hdtv. it has a low, medium and high setting. the low setting is rated at 6500k but the medium and high settings don't seem to be rated.

i read that 6500k is the optimal temp for hdtv, bit it seems to make things too orange or warm. the high setting gives everything a slightly blue tinge. medium seems ok, but i wonder if maybe it IS supposed to be set at 6500k and i just need to get used to the pic. high and low seems to make the difference between a beige shirt and a white shirt. too bad i don't know what the color of the shirt originally was.

btw, here is some info i'd like to see if you agree with:

You might want to get your HDTV calibrated by a professional if you're looking to get as close to 6500k as possible.

You may not like the natural look that 6500k gives off, so you may just want to stick with the Medium setting, which is slightly more blue and less red. White should look slightly reddish if your set is calibrated to 6500k. Gray should look 'gray' and not have a 'blue' look to it.

If you're used to looking at TVs that are around 9300k, white may seem normal but it's actually way too blue and is not natural in real life. Take a look outside on a sunny day and look at anything that is white in color. Is it bluish or reddish?

6500k does take some getting used to, but you eventually realize that this is what colors look like under natural daylight. The problem is that most people prefer the 'bluer' look because it is what they are used to from watching TVs that were calibrated more towards 9300k.

yes, the pic did look more natural with the 6500k setting. i'm just not used to it from always having it set to high.

btw, if it makes any difference, i mainly watch movies at night on SD and HD DVD in a dark room. no lights.

I used to view my CRT TVs and computer monitors at 9300k. I liked the brighter look of 9300k even though it wasn't natural. 6500k looked very red and I just couldn't get used to it. After calibrating my current TV and LCD computer monitor to 6500k, I realized that the colors were more realistic and more easy on the eyes. It took a few days for me to adjust to it, but I soon became addicted to the natural beauty of 6500k and will never go back to higher color temps if I can help it. Films take on a whole new look and experience once you go 6500k.

It's possible that your "Low" setting is too warm and is reading well below 6500k. 6500k shouldn't look too reddish and definitely not orange. It should look more earthy. Of course, a good way to test it is to view a grayscale ramp on a calibration DVD. Grays should appear naturally gray without any red, green, or blue color tint.

for some reason, my pc monitor has a 6550 setting. ? along with 9300 and 5000.

You can't always trust those settings. Mine has 9300k, 7500k, 6500k, 5400k and 5000k. The default 6500k setting out of the box was a tad too warm, so I had to make individual adjustments to the RGB settings to get it closer to 6500k.

With TVs you generally need to enter the service menu to make precise adjustments to RGB bias and gain controls to fine tune the grayscale. You can either have a professional do it or buy a colorimeter and do it yourself. This should only be done if you really want the grayscale to be tracking at 6500k.

i don't even know how to get into the service menu of my tv. it's a mitsubishi ws-55315 and i've never been able to find any info on how to get to it's service menu anywhere.

If you get in there just be careful and write down settings. Also remember what colors work together, and what colors are each others opposites. For example, there is yellow in red so those to will work together and affect one another. Also oposites, the opposite of green is magenta, yellow is blue, and red is cyan. Moving color towards one will take away from the other. It can be tricky.
