AMD HD 6450 Settings greyed out?

[joecrow]

I have recently built a new desktop PC with an AMD HD6450 graphics card but was surprised to find that after installing the latest drivers and CCC (14.4) some of the settings which are ticked are greyed out and can't be changed, notably "Brighter Whites" and "Flesh Tone Correction" both of which, and others, I normally disable. I tried an older driver package (13.4) but got the same results. On my HTPC which uses an AMD HD6770 (also at 14.4) these options are not greyed out and this was not a problem on my old desktop with a HD5450. Am I missing something to enable the changing these controls or is this a feature on the HD6450?
The only thing I found on Google was with respect to the scaling setting, which in my case is one of the few that is not greyed out! Any HD6450 uses out there please let me know if you have the same or not?

If the settings are greyed out.....more than likely, these are features included with the software, that are not supported by the hardware.

That is a strange one isn't it? I just did a comparison 5450 to 6450. Those two are very close, with a slight advantage to the 6450.

I also compared the 6450 to 6770. Not surprised that the 6770 largely out classes the 6450.

Maybe your bios needs an adjustment.

Many thanks for the responses I'll take a look in the bios later, any suggestions as to what might need changing? (Gigabyte mobo)
Also it is strange that the greyed out settings are ticked so I would assume they are enabled
Another HD6450 user could confirm/deny my observations. Anyone out there?

Possibly worth looking in the registry?

I remember having to set certain items for my old ATI cards using regedit - or they would keep reverting to defaults.

I'll see if I still have notes on where the keys were. I have a feeling that STC might have posted about this a while back......

What about the power supply? Is it at least 400 watts? http://www.amd.com/en-us/products/graph ... 6000/6450#

Hi
PSU is 500W and I could not find anything in the bios that I would appear to effect the function of the graphics card so... I borrowed my old HD5450 back and installed it again with CCC 14.4, no more greyed out settings everything is available and can be changed! I am coming to the conclusion that the HD 6450 is faulty (also it ran really hot) or if not I don't like not having the ability to apply different settings, either way I am going to return it and get something else.
Any Suggestions?
Needs to be under $100 (€80) I don't need a super card for this PC just a reasonable general purpose one. I am familier with AMD but not fixed on them, also it does not have to be passively cooled, though I always found those little fans fail after a couple of years and you can never find a replacement.

Are you using RGB or YCbCr?
Do you have another TV/HDMI monitor you could test connect?

Long shot, but maybe something to do with the HDMI handshake is disabling some features?

YCbCr but tried RGB also , no change

Do you have another TV/HDMI monitor you could test connect?

No but the HD5450 works fine with the same monitor and connection (HDMI)!

Long shot, but maybe something to do with the HDMI handshake is disabling some features?

I agree, I would have been interested in trying it connected via VGA but my chassis does not allow clear physical access to the graphics card VGA plug so that was not possible.
The success with the HD 5450 was pretty much the last straw for me I have given up on the HD6450 and as mentioned on the ealier post I am looking for suggestions for an alternative.
All tips gratefully received
Also many thanks for all the responses to date.

The HD 6770 price has come way down in the 2 years that I have had one. Ebay lists one for 70 US dollars

I have an MSI HD6450 & just looked at the settings & "Brighter Whites" and "Flesh Tone Correction" and others are grayed out.

If go into Quality > Video Quality and uncheck "Enforce Smooth Video Playback" this allows me to access to the "Brighter Whites" and "Flesh Tone Correction" and & then they can be unchecked.

IOW checking "Enforce Smooth Video Playback" grays out a lot of settings, at least in my setup.

I'm using an older CCC driver (8.982 per Device Manager) because it works & I've been reluctant to change it.

[Crash2009]

I like those older drivers too. My 6770 is using 8.850 with no CCC or Hydra. Device manager reports the date as April 2011, so, I think that makes it Version 11.4, Sometimes I wonder what I might be missing.....maybe just headaches

That was the problem, spot on, after unticking the "Enforce Smooth Video Playback" The Brighter Whites and many other settings are no longer greyed out! (ccc 14.4)
Very good tip, many many thanks.
Looks like I won't need a new card after all, shame I was seriously considering the AMD R7 240, most reviews have it way ahead of the similarly priced nvidea GT640.

Here's some additional information that came to mind about grayed out settings when I was playing with Dynamic Range.
http://www.avsforum.com/t/1463611/unabl ... t_23088878

Short version -
If I selected "Enforce Smooth Video Playback" the Dynamic Range was set to 0-255 Full, no matter what it was before it was "grayed out". IOW even though the DR is "grayed out 16-235" it is really 0-255.

Something similar may also happen to "Brighter Whites" and "Flesh Tone Correction". IOW checking "Enforce Smooth Video Playback" may automatically disable "Brighter Whites" and "Flesh Tone Correction" even though their boxes are checked. Or it might automatically enable those settings. IOW checking "Enforce Smooth Video Playback" appears to set at least some options a certain way no matter how they where checked or unchecked before being grayed out, & display in the grayed out condition. You'd would have to experiment to see what its "forced" setting does to "Brighter Whites" and "Flesh Tone Correction".
