Banding Issue MBP 17 quad core I7

Jason Moore
Hi there has anyone had this problem yet with Capture One 6
I have a new MBP 17 Quad core I7 with an anti glare screen.
When I look at images where there is any colour or tonal graduation or use the vignette tool I get a coloured banding effect where the graduation starts....almost like a halo, like the screen quality is set on very low resolution...only it's not. The same images on my old MBP 17 don't have the banding which implies it's a screen problem....any ideas?

    Tweak the OpenCL setting from CO6's Preferences and see what happens.

    Thanks I will try. But the processed images have the banding when opened in photoshop, the same file on my old MBP is ok...gotta be the screen I guess.

    Some tips: Check in system preferences the amount of colors (thousands or millions?) for your screen. And transfer a processed image from your new to your old MBP and compare.

    MacBook Pro's still use 6bit displays and are terrible at colour or gradient ramps. The newer displays are quite good with colour accuracy though. The only true way to check you file is to hook up to a quality external display with and 8 or 10 bit panel.

    I've experienced this too, especially in blue skies. When I looked at the same image on a better screen it wasn't there.

    Thanks for your reply.
    So I tested the same EIP and processed tiff on my old MBP 17 and there is no banding. I hooked up an Eizo screen to my new MBP and no banding, so looks like its the screen. Gonna take it into the apple store tomorrow.

    Also if you profile your screen this usually makes the banding worse.

    So the Apple store replaced the screen. But the screens on these new MBP's are not to my liking. Before on my 2009 MBP to calibrate was a very uncomplicated affair , the software really struggles with this one.

    Yep, profiling your screen will intoduce more banding because you usually end up pushing the display out of it comfort zone. I personally only adjust the brightness of my screen so I can judge exposure, then connect to a qualty monitor for all the rest of the work.

    Out of interest have you set the white point to native or are you trying to hit a target during calibration? The banding may well be reduced if you choose native white point.

    Hi Gareth
    Yes white point set to native, I have tried all sorts of variations and have decided to leave the laptop on the standard factory profile (which is closest) as it seems impossible to calibrate/trust....I'd like some kinda on screen control to reduce the contrast and saturation which currently is miles from what the image will look like when printed. I think the screens on the new MBP's are designed with the amateur market in mind . My old MBP (2008) gives a much more accurate rendition of tone,contrast and colour saturation.
    I hear the banding is glue that still hasn't dried properly ,apparently they were trying to ship them out the door a little too quickly...who knows !

    I have the 15" version of the same setup waiting for me when I get home. Please let us know if your situation improves in any way. I use a calibrated second monitor for the work, but will need to use the MBP screen on location as is from time to time, so have joined this discussion for updates.

    Hi Kit
    You can press ctrl alt option and the comma or full stop keys to reduce/increase contrast....no where near as much as is needed though. No such keys for desaturating the unrealistic colour display though.
    In the end I left the display on the Apple LCD profile ( which seemed closest) as all I have spoken to say don't try and calibrate you're wasting your time.
    Really think they should remove the word pro from the name as the new MBP's seem to be aimed at the amateur or film watching market....in my humble opinion, pretty punchy display but useless as an accurate colour/contrast guide for printing from.
    Like you Kit, running up and down on a beach shooting is no place for an external monitor so that's a non starter.
    Spoke to Apple who were apologetic but offered no resolution ...needless to say I am massively disappointed with the upgrade.Quad core has reduced processing time ....a LOT, in it's favour.

    This option is not available on the new operating system on the new MBP

    Thanks for the heads-up. It is removed in 10.6 Snow Leopard.
