lower contrast

also, whites and blacks don't have saturation, only colors do... so, I think you mean whites are too bright or gamma is too bright (near whites)

Yeah, you can't have oversaturated whites. You probably mean white crushing or clipping. Try playing around with your contrast and brightness settings.

The only way that reduces it is turning contrast down lower than 50 which is a bit dark which kinda sucks.

Try posting a request for help / advice under an owners thread for the Manufacturer / Model that you own.

Get a copy of the AVS HD709 disk, and view the short videos on calibrating / adjusting a HDTV.
Recall that there is not only a Preferred Sequence to follow (ie: First Adjust THIS, Then Adjust THAT...), but also some advice that you might have to go back & re-check the early settings, as they can be impacted by the later ones.

Viewing environment / preferences may also play a role, but have read a number of posts from owners who have stated that they felt Post-Calibration settings were a bit "dim," UNTIL they had time to grow accustomed to them.

I have a lg 42pa4500.

The darkest blacks are very black but the whitest,of whites are quite over bright/saturated and can't really get rid of the white problem without turning the contrast down way too far.


Is this normal for a budget plasma?????

did you change temp from cool to warm?
curious that the whites are too bright.
that sounds like an LCD.
must be the temp of the white.

It reminds me of how a CRT would look when the picture tube is gone(if you turn the contrast way up it would look oversaturated on brights and whites).Theres sometimes noticeable bright outlining the edge of -example baseball player football player too.im referring to the very brightest whites on the screen.

I've tried every contrast and brightness setting and the BRIGHTEST whites are always at least a little oversaturated.I don't remember this on the d630 or lk520,although maybe I just did not notice.



I just want to know if Plasmas have this tendency(this is the first plasma ive bought)I'm trying to decide whether to try another pa4500 or get my money back or am I nitpicking too much? It was$400 plus tax.

If you post a complete list of your settings someone may be able to help you online .
If you bought it locally ask to have someone come and take a look at it , before you take it back for another plasma of the same or different model .
And again no it is not normal for all plasmas low or high end to look that way .
If you are sure in your settings and dont like it send it back and get a LCD if you think you do not like the picture from a Plasma.

I used an iPad which is close to 6500k with grays bars and video essentials DVD with gray bars and tried to get them to look the same on the tv.first the 2 point then the 20 point.
I notice level 5 adjusts the color of the black bars.The color of the bars are greenish or reddish purple depending on channel and the brightness control.The lcds seemed easier to calibrate than this plasma.

I only used the 2 point method and eye balled it using the inner patterns or gray screens . and am very happy with the grays .
Here are my settings , all eye balled. HDMI Roku
Energy savings - off
Expert 1
Contrast 83
Brightness 60
H sharp 12
V sharp 8
Color 42
Tint 0
Dynamic contrast off
Noise reduction off
Black level low
Color gamut standard
Edge enhancer off
Color temp medium
Method 2 Point
High
Red -14 Green -12 Blue -8
Low
Red -14 Green -14 Blue -10
In color management I made adjustments to Saturation only
Red -12 Green -6 Blue -4 Cyan -3 Magenta -8 Yellow -2
These settings are very similar to the OTA TV settings I use although I set britness to 53 - 55 .
I am very happy with these settings , and the whites seem normal . I like lower color settings I feel It gives a more natural look to the picture .
I used a color bar I found on Netflix to do the Saturation settings .
The outline problem with football games may be caused by your sharpness settings being too high.

seems like a high contrast setting.A bit torch mode.Depends how bright the room is too.Mine is never overly bright.I have had sharpness 40 and it looks good but brings out every wrinkle on a person.

I tried to match iPad color bars Up with tv channels color bars adjusting color managements luminance tint saturation and ended up with some real bad outlines around people so I just set everything back to 0 except the red is too purple so adjusted tint.
