Lightroom Classic: Monitor 2 in lightroom classic blurs when I try to work in develop module.

Perhaps this is a known issue?

I have two monitors connected to my macbook pro. One via hdmi. Two via thunderbolt. When I open Lightroom my library window is on monitor One. That image is always sharp. On monitor Two it's sharp until I hit 'develop' module. Then that image on monitor Two blurs. I noticed if I click on Library again monitor Two sharpens up again. But in develop if say i tap on clarity, exposure, contrast, texture, etc. it blurs again.

I've tried it with graphics acceleration on and off and it's the same.

And dang, I thought adobe had fixed the acceleration issue. Now it's worse. Before I just turned it completely off and lightroom was working great. Maybe I should go back a version? Can I do that? This blurring of the images on monitor Two never happened before.

Also, monitor Two is a more recent 27" nec that i use for print color and processing work. The monitor with my library on it, monitor One, is like 11 years old, another nec and still works fine for the library and all the controls in develop and print modules.

If it matters, my laptop is a 2015 mid-summer model. macOS is Catalina 10.15.7. 16gb of ram. Two graphics cards. 1. amd radeon r9m370x with 2 gb of video ram. 2. The intel iris pro 1536 mb.

thanks for any advice/help
Morris

the future is now

Short PS. I see via the creative cloud window I can revert to 10.1.1

Will my current, saved catalog play nice with this older version? I don't remember if 10.2 updated my catalog to something unusable if i need to go back?

thanks

I assume that you realize that Lightroom will only use one video card. You didn't mention the resolution of your newer NEC monitor but your 2GB video card can only support a QHD monitor. If the new NEC is 4K then you need a 4GB video card at a minimum.

Brief update ; since I've reverted back to 10.1.1 i no longer have any problems with images blurring on my #2 monitor. I'm assuming the problem is with version 10.2 since my setup works fine with the older version of LrClassic.

I am having exactly the same problem. It started happening just after the most recent Lightroom Classic upgrade. I have a 2018 MacBook Pro, 2.9 GHz 6 core Intel Core i9, 32 GB memory, 2 TB ssd, Radeon Pro 560X 4GB. Second monitor is a BenQ SW2700. Running Lightroom Classic version 10.2. MacOS version 11.2.3 (Big Sur).

I use my MacBook as my primary Lightroom monitor. I use the BenQ window as my auxiliary. When I am in Library mode, images on the BenQ are sharp. When I click into Develop mode the images are fuzzy, particularly when I go to 100% image. This never happened before. Like Mr. Taub, I have tried turning off graphics acceleration and the issue does not change. This is very disappointing.

I have not downgraded yet. I have adapted my workflow for now but if this is not addressed quickly, I will need to downgrade.

I did the clean install that you described and it changed nothing.

The image that I am working on makes no difference at all.  In library mode with my prime display (my MacBook Pro) in grid mode and my secondary display (my BenQ SW2700) in loupe mode, if I click to go to develop, the image on the secondary display goes very fuzzy.  It is much worse if I then enlarge the image to 100%.

I had LrC do a system information display.  For some reason, LrC has my MacOS version all wrong.  I am running MacOS 11.2.3.  The listing indicates that I am running MacOS 10, version 10.16.

Hi Morris,

1) Does it blur on all images, or some specific images in the secondary monitor?

2) If it is specific, any information on the type of image, or whether those image contains any edits?

3) You said when you try to play with sliders like exposure/clarity it appears again. So is that momentary? Meaning, does it stay blurred if the slider is held and becomes sharp when the sliders are released? Or as soon as you move a slider it blurs out and never sharpens again?

4) Just to confirm, initially you have posted that issue occurs with both GPU acceleration On and Off. However in one of the reply comments from you above, I see that the issue is resolved if the GPU is off. Am I understanding this correct? To re-iterate issue is present only with GPU On?

Thanks,
Arjun

Same Problem here (blurry zoomed image on secondary monitor),
after color shift in library when zoom image (resolved in last update)
new color shift in print module :-/

and now this blurry zoomed image on secondary monitor

think seriously to switch to capture One
Lightroom is a wonderful software but lots of bugs

PS: already, uninstall / reinstall / delete prefs / etc ...

Hello, 

I am having this same issue as described by previous commenters in this thread. I have taken the steps already advised and still the same results. As soon as 'develop' is selected the images blur.

I have this same issue.  I did all the fixes suggested above and they did not work.  It is not the monitor or connection, Photoshop presents the same image on the second monitor at the same resolution, sharply.  2015 MBP, 16gb.

Have any of you tried Lightroom in single monitor mode with Lightroom at 100% on the external monitor?

I’m picking up a blurred image on my second display in the develop module using Lightroom classic 10.2 

Any ideas why ?

I also have run into this problem after installing Lr 10.2. 2020 17" iMac, with secondary monitor Dell U2720Q.  2nd monitor connected via TB3 (daisy chained behind a OWC Thunderbay 4).

For me the issue is intermittent, and I can't (yet?) determine the pattern.  When it happens, it happens immediately on changing from the Library to the Develop module, or when moving from one image to another in Develop.

When it occurs, sometimes I can resolve it by moving back or ahead one image and then moving back (this trick worked for a long time with a similar prior versions bug where the image on the secondary monitor would be "ghostish," that is, very light and faded, which I haven't seen yet on 10.2).  Other times, moving ahead/back and then returning does NOT resolve the issue, and I just can't use the secondary monitor on that image.

Waiting does not change anything; it doesn't appear to be an issue of Lr building a new preview.

I'll keep an eye out to see if I can discern a pattern that would make the bug reproducible at will.

Hi there, I'm seeing this too.

MBP 13” late 2013, 16GB RAM running MacOS Big Sur 11.2.3

Second monitor 4k LG 27UL600. Use graphics processor is OFF. Problem appeared with LrC 10.2 and happened permanently and consistently.

Tried reinstalling LrC 10.2 as described above, didn't help. Downgraded to 10.1.1 and it works correctly.

I hope this gets resolved sooner than later. I waited 7 months for Lightroom to support tethered capture for my camera (Nikon Z5) and that was the main feature in 10.2 for me. However seeing images clearly is more important at the moment so I guess I'll wait (even longer).

I am experiencing the exact same issue using Lightroom Classic 10.2 on Apple iMac Pro with second LG Thunderbolt 27in monitor.  Second monitor performs as expected on all other apps, including Photoshop 22.3.0.  The problem started with update from 10.1.1.

If I revert to one monitor mode and switch back to dual monitor the second monitors displays correctly until I click anywhere in the Develop module.
