    Please help me fix this. I have tried changing the image caching sizes, video card acceleration, and still nothing helps.
    Here I include a screenshot of how it looks, and how Windows Preview renders an image at the same zoom level. The difference is huge, I feel like im working with out of focus images. At 50% or higher the image is crisp, when you zoom out lower than 50% it becomes super soft.

    Example:

    Please look at the image at full size.
    Thank you!


    It is certainly not normal for V12 on Windows. Some more information would help.
    Which version of Windows, it looks like 7?
    What monitor resolution is set?
    Do you have recipe proofing enabled?
    What preview size have you set and what camera / size is the image?

    As I said it is not usual so it looks like there is something different in your setup. Certainly everything is fine on my Win 10 (1903) C1Pro V12.1.4 setup.

    Windows 7, all the service packs and up to date.
    Monitor res is 2560x1440. Tried setting Cache of preview image size to various settings, should it be the same as my monitor resolution?
    I never used recipe proofing, I just tried enabling it and it does make it a bit better, about 50% better, but still not as sharp as Windows preview. And it constantly displays "Proofing" on top of the photo. I dont want it there.
    I dont remember when it started happening but it definetly wasnt there in previous Capture One versions.
    All photos are from a 24mp camera, so, 6000x4000px.
    Thank you so much for taking your time to help me.

    Well I have the same screen size as you and have no issues. ☹️

    You don't need the preview size to be the same as the screen resolution as you never use the full screen. It is normally recommended to use a preview size one or two below. My preview window works out at around 1800 pixels wide so you can use 2048 or 1920 and save some disk space for the previews.

    I would raise a support case with Phaseone through your account page. May be an issue with Win 7 as that is the major obvious difference between our systems. You are on V12.1.4 ?

    Do you have a dpi scale in windows above 100%? Try it.

    Yes, I have DPI scaling enabled in Windows. It's at 125%, otherwise everything is too small on my screen, unusable.
    I have noticed that in C1P, when I'm zoomed in at 100% and then I double click the photo, which zooms out to Fit to Screen, as image shrinks it becomes super sharp for like .5 - 1 second and then it snaps to that blurry state, it's like it's applying something to it?
    Is it possible to work with pixels directly, and not with the generated preview?

    Ok, so apparently it's just how C1P does things.
    I just dont understand the advantage of doing it their way, maybe 20 years ago, ok, the computers were slow, but today?
    Here's what's happening:

    Sorry I explained bad. If you use dpi scale above 125% try at 100% only to see if it's affecting. You can submit a ticket if it is the cause.
    I think I was affected with this blurry image in 12.1.x and try the 100% scale and I see fine image now, but I had an 32" 4K monitor and I can see all small but I can read all and I not changed the scale after.
    When I'll go home I will try another time changing scales.

    Scaling is recommended by Windows to be at 100% for my Dell 2560x1440 monitor by Win 10. My eyes are I suspect much older than yours and the text etc is fine.

    I suspect that you have text scaling / icon scaling set, not at default, somewhere in the system and that is why you are having problems. Something is certainly different in the display compared to my Dell monitor / Win 10.

    Thomas's comments only apply to Macs. There are a few Mac's which experience this issue but it is only a small number and is not reproducible by most others, therefore very difficult to resolve.

    See my comments about the difference between our very similar monitors regarding the size of text / icons you are seeing. This is likely the root cause of your issues.

    My monitor is also Dell, but having the DPI at 100 is really not an option for me - everything is too small to be comfortable.
    Images are super sharp in every other program: Camera RAW, Rawtherapee, Darktable, Camerabag, DXO, etc. And even in C1P they flash as super sharp and then revert to the blurry state, so it is possible for it to work, it just doesnt. The link I posted explains it pretty well I think, C1P doesnt render the changes to image in real time, only when set to 100% image size. Exported images look great.
    I don't understand why we can't work with pixels directly and have to work on "thumbnails" switching back and forth depending on zoom level.

    What are your computer specs? changes should happen real time no matter what zoom level.

    As I Have the same monitor and our experiences of the Windows scaling at 100% is so different I think it is logical to put the problems you are experiencing down to the fact you are using Win 7. What else could it be?

    One of the big improvements in Win 10 was with handling scaling on higher dpi displays. You need to raise a support issue with Phaseone although I am not sure how much priority such a request will get considering Win 7 goes EOL in January. I believe it is still possible to actually upgrade to Win 10 for free if you download the ISO from MS and do a ne w install. Google is your friend 😊

    Hi 

    You are having exactly the same issue as me!!! Tried everything also - scaling, resolution etc etc... - my hardware is good and software up to date. I'm on Capture One 20 and had this with the previous version. Only issues are in Capture One no other programs. It's so frustrating.

    I love C1 as a Fuji shooter but it is making me reconsider LR. 

    Problem is from "FIT" to 17%. Next roll of the mouse wheel that take the zoom to 25% and images are beautifully sharp.
