P: Compare View on 2nd Monitor shows no image on Zoom.

[Job56]

After LR Classic 13.0 and update 13.0.1 Lightroom is behaving weird on my second monitor.
Before I could use the compare mode on the second monitor when in the develop module on the first without any issues.
Could zoom in and out on the comparisons.
After the update this behaves odd.

Sometimes it will zoom in and out as before but most of the time it doesn't and one of the selected pics for comparison won't even show (just black) or sometimes even zooms in at a different percentage compared to the other. This only occurs when in the Develop module.

Switching from Compare to Loupe on the second monitor sometimes won't work either - display goes black.

When I switch to the Library module on the first screen there's no issue.

I've got a very robust Windows system with 32 GB of RAM and a NVIDIA GeForce RTX 3060 Ti 8GB of RAM which before (v 12.5) just did the job without any trouble.

Seems like Adobe rushed to do this update but forgot to test it thouroughly.

I am going to merge you into that Acknowledged thread.

Still happens on 13.0.2, but I wanted to add I have a bunch of older scanned images that work fine in develop second screen. Only the images from my camera are doing it. The scanned images are much lower resolution and they are not raw.

A bug appeared in version 13 of LrC: 100% zoom no longer works on the second screen, ONLY IN DEVELOPMENT MODE.

More precisely, zooming to 100% is done completely off-center (bottom left), which often leads to a black window. If we try to recover the photo (by PAN), only part (bottom left) of the image (truncated) is accessible.

I temporarily reinstalled the latest V12 (which works perfectly), which proves that it is indeed a bug on V13 (including the latest version).

-Windows 10

- Intel® Core™ i7 4770 CPU @ 3.40GHz

- 8 GB RAM

-NVIDIA GeForce GTX 1080

I installed the update 13.02. sadly the bug is still there on my second screen in developer mode zooming in. hoping for another update taht will definitely fix it. It is an annoying bug !!

[duriv73]

And I also noticed that the quality of the image in the second window, ALWAYS IN DEVELOPMENT mode (in adaptive zoom) is bad (oversaturation, no contrast)

i cant zoom in on my second monitor to 100 procent. it just show a small fraction of the picture and its aint solved by the latest update.

So after a long wait for a newer version after 13.0.1 I tried out 13.0.02 today but no luck still.

Partial blackout when zoomin g on seconde screen and grid view very unresponsive when changing flags or color labels. Creating panoramas is also incredibly slow. Sorry to say that but version 13 seems to be not to be production ready. So pros using this for business: Stay away from this until those issues are fixed for sure!

!! Ah yeah - do not forget to make a backup of your catalog as it will be converted when switching to from Version 12.x.x !!

If GPU accelaration switched then the image long time to appear sharp on zoom in view

Same problem.

Not fixed with LRC 13.0.2

Nvidia RTX4070

[StanG]

Second monitor preview mode, using Loupe.

Zoom to max 66% works, 100% does not work, shows all black image.

My second monitor is also acting wonky. Latest version of LR. Nvidia RTX4000 Win10.

[georges13174760]

I have updated to LR13.0.2 and now the second screen zooms properly in Develop IF AND ONLY IF I turn off my RTX3060 GPU. You are half way there.

Alas, 13.02 isn't halfway there. Adobe admits that 13.02 did not address this bug. Turning off GPU acceleration in 13.01 also restored normal behavior to the 2nd monitor in Develop mode at the price of slower performance. The problem remains that Adobe issued an update (LR Classic 13) without testing to see if it worked properly with the NVIDIA graphics cards that most of us use.

When in develop my second monitor loupe view doesn't zoom normally.

I get a black screen or zooms to a part of the image and the rest of the screen is black. 

This only happens in develop, Library view is ok. 

Happens with  all file types, nef, jpeg, psd.

Started with Lightroom classic 13, I've been hoping for a bug fix but nothing in last update.

Lightroom 13.0.2

Windows 11 pro 22H2

Intel i7 -8700

Nvidia GeForce GTX 1660

96GB Ram

It's a known issue. See

https://community.adobe.com/t5/lightroom-classic-bugs/p-compare-view-on-2nd-monitor-shows-no-image-o...

[Alexosterrieth]

I'm having the same issue. It only occurs when I've got GPU accelleration, which I need because otherwise my laptop doesn't perform well enough to run LRC...

[duriv73]

I confirm your message:

I deactivated the use of the GPU in Lightroom Preferences, and
everything is back to normal in terms of display.

THANKS. This "saves my life", while we wait for Adobe to look into it,
OR AT LEAST SAY IT CARE.

NVIDIA issued a new Studio Driver today, version 546.33. Can someone from Adobe comment on whether this update fixes the GPU acceleration problem that is the basis of the issue in this thread? Nothing in NVIDIA's release notes indicates that it does.

[duriv73]

Je l'ai installé. Non, ça ne règle rien.
La solution est dans le camp d'Adobe (qui ne répond pas au téléphone), pas
de NVIDIA.

[jrsforums]

Nope...no fix there...just tested 

[georges13174760]

It seems to be working fine on my RTX3060 system now! Finally! Did you restart?

[jrsforums]

Yep....3090TI. Checked both library (works) & develop (don't)

EDIT: Reboot one more time.....same

[georges13174760]

Ooops! Spoke too soon, I guess. Right in the middle of an editing session, it suddenly quit working again.  Rats!
