Hello, I use a MBP 16" with i7 6 core processor, AMD Radeon Pro 5300M 4 GB and 16 GB of RAM. All my SW is up to date. I also use a Benq GW2480-B coonected over a cable by iVanky, USB C to HDMI, model LANVADA-C31. None of all other apps I used give this issue: Luminar 4, C1 express, Aurora HDR 2018, BR o LrC. I did not try with Gimp or Affinity Photo.
I tryed to connect the Mac to my TV, with the same cable, same issue. I doubt it is a the cable since the problem is relate only to the picture, not to the interface.
Here is a link to a video that is showing the problem: youtu.be/we_uBvQSlTk
I restore Mac OS completely: ko. I cleaned tro clean everythyng with cc cleaner tool and reinstall all again: ko. The Adobe support suggested to disable the GPU use in PS, but this is a problem for me since I need the liquify filter.
I tried to change the external monitor settings in Mac OS as well, both color profile and frequency: KO
I would be very suspicious of the cable or the port on the MBP or monitor. Have you tried all of the USB-C ports? Same problem? I would try another cable before anything else. I'm using an old Dell external monitor with my MBP 16" through and adapter dongle. No problems like your.
Hello, I did not try with another cable though I did try to change the port to the second one on the same side of the Mac: KO.
I doubted it was a cable problem since I thought if it was it should hit al programs and also PS interface, whereas it hits only the picture side and it's even intermittent.
I am ready to buy another cable and try it out though, can you suggest anything? Thank you
Hi, I tried to reduce the resolution of the screen to 720p and it stops flickering, but it's pretty uncocofortable to work like this. I now bought a USB-C to Display port by Belkin, it's quite expensive but I can give it back on Amazon if it doesn't solve the issue. We'll see.
I use that DP adapter on my MBP 16" for the connection to my 24" external Dell monitor and it works just fine.
Which adapter exactly?
I'm not sure... I can't check it right now.
I solved the issue by changing the cable, now it stopped flickering. I move to a Belik cable, no more USB-C to HDMI but USB-C to Display Port. It's more expensive, but worth it.
Not, an issue is still left. Whenever I start postproducing an imagine I do it with LrC. No problems there. As soon as I ask the program to continue modify the picture in PS, the same picture in PS looks terribly differing (saturation up). If I open the liquify too, it looks normal. If I open Luminar 4 as PS plug-in it looks normal. I need to chek how it looks with Camera Raw but, in any case, in PS with the new cable coming from LrC. Any idea?
Glad you got the flickering taken care of. That was one of my first suggestions.
Start a new topic on the forum about the color issues. No one is going to see this under it's current title.
