thanks for the explanation. I will have a play around with my monitor and see if i can get the settings working, if not its not a massive hassle to turn HDR on/off when im editing as i tend to do it all in big batches. im currently using a AOC Agon AG322QC4 , so a gaming monitor more than a photo editing one, though does surprisingly well once calibrated properly.

Ok found it, if i turn off HDR in windows displays settings solves it. Turn it off in the monitor no difference.

Yes only 8bit though, i did try to turn it off but made no affect. Its strange how in affinity on the same monitor the main picture is dull but the preview is bright. also updated my gpu drivers just in case and made no difference

Hi i uploaded a file i had previously edited in 1.6 and it worked fine to the dropbox, this file in 1.7 also goes underexposed. So pretty sure its not a file problem but no harm in uploading for you to try. I am also on 1.7.1.404 and it still does it to me but strangely only on 1 monitor. If i print screen the image, it goes back to looking fine on the same monitor! It also displays fine in the preview in the bottom right but underexposed in the main picture. I am shooting with a nikon d500 if that makes any difference. i did find a workaround which is in 32 bit preview, enable HDR mode - and add 1.6-1.8 stops of exposure to get back to where it should be.

Just to add i am getting the exact same issue, no issue with importing files in 1.6, opened a file in 1.7 and its way underexposed. in Fastone viewer it looks fine, i would say in affinity its almost 2 stops down on what it should be. Add exposure just doesnt look right either. Tone curve makes it darker, changing from 32 bit to 16 bit also makes it darker.
