Poor Lightroom 4.4 performance when laptop connected to an external monitor
Apr 20, 2013

Hello everyone,

I have recently purchased an external monitor to be able to view my photos at a higher resolution (1920*1080). However, Lightroom performance is extremely bad and the sliders are laggy when I just use the monitor that I have bought. Doing the same task on my laptop monitor takes much less time and runs perfectly smooth (the resolution of the laptop is 1366*768).

Is this an issue with Lightroom 4.4 or is it my because my laptop is not fast enough? 
Any helps would be appreciated!

It is difficult to comment fully when you give us no details other the software version you are using.

What are the specs of your laptop - RAM, CPU, GPU (AMD, Nvidia, or Intel)?

What OS?

How are you connected to the monitor?  VGA, HDMI?

Are you trying to run the laptop and monitor screen at the same time - i.e. Spanning across the two displays, cloning, extending?  or are you using a single display i.e. the external only?

.

Right off the top I think you could be running into issues between the resolution of the external (1920x1080) and the resolution of the laptop (1368x768) if you are attempting to extend the desktop across the two displays.

Perhaps related on the resolution issue but also a concern due the following, the laptop likely only has a single LUT (Look Up Table) in the video pipeline.  The LUT is used to store information used to correct the color of the display.  In most laptops the laptop screen, VGA port, and HDMI port share this LUT.  So when running both the laptop and external at the same time there is going to be a problem with either the laptop screen or the monitor screen in terms of color and it will likely be the external that is incorrect unless you took steps to ensure the monitors ICC profile is being used.

Sorry about that. I will provide all the information here.

The Lightroom version is 4.4 and I have a laptop with 8 GB ram, a 2.4 GHz Intel Core i5 CPU, the GPU is Radeon HD 5650.

What OS?

My OS is Windows 7 64 bit

How are you connected to the monitor?  VGA, HDMI?

The connection is via a VGA cable

Good point. I just want to use the external monitor (single display) so I use it as a projector and I do not extend the displays. I just wanted to edit my photos with a higher resolution monitor so that I see the editing flaws in them more easily.

As I mentioned, I'm not extending the display so it could something else.

Perhaps related on the resolution issue but also a concern due the following, the laptop likely only has a single LUT (Look Up Table) in the video pipeline.  The LUT is used to store information used to correct the color of the display.  In most laptops the laptop screen, VGA port, and HDMI port share this LUT.  So when running both the laptop and external at the same time there is going to be a problem with either the laptop screen or the monitor screen in terms of color and it will likely be the external that is incorrect unless you took steps to ensure the monitors ICC profile is being used.

.

The main issue is the processing speed and the huge lag during editing of the photos. I can be okay with the color even if the color is somewhat inaccurate but very slow crop function or exposure change is just intolerable. The interesting point is that lightroom only takes up up to 30% of my maximum CPU potential during hardcore editing and when it lags. So, CPU overload might not be the reason.

Thank you again for your help!

All of the above, combined.

The LR 4 rendering engine is something of a resource hog.

The high resolution monitor means it has to do a lot more work (almost double if you do the math).

Laptops are usually a tad slower that their desktop equivalents because of design compromises made to conserve battery.

There are no easy fixes. You could try the LR5 beta which is claimed to have better performance. It did seem that way to me after about 10 minutes actual use. But that's not a deeply held conviction

You could also...

1. Have dinner while LR generates 1:1 previews during the import. That can help.

2. Import with no noise reduction, sharpening, or lens corrections. With those off, performance is quite a bit better. Apply those settings at the very end of your workflow and let the thing grind away on the final rendering and export.

Or, just try different software ;-)

There doesn't seem to be any "method to the madness" as far as LR4 performance is concerned.

Some users report it works great on lower spec hardware, and some users report that is' horrible on nicely spec'd state-of-the-art systems.  IOW, throwing faster hardware at it doesn't always work. 

IMO, with a modern Core i5 CPU (even if it's a dual core mobile model) with a discrete graphics chipset and 8GB of memory, a modern app like Lightroom should not have horrible performance with laggy response to sliders, etc.  But, that seems to be the way it behaves on some machines.

So, you may want to try different software and see if something else works better for you.

As Malch mentioned, a new LR5 Beta is out now.  So, you may want to give it a spin and see if it works any better for you.  Get it here:

http://labs.adobe.com/technologies/lightroom5/

Personally, I use Corel AfterShot Pro instead of Lightroom.   You can download a trial version of it that works for 30 days to see if you like it or not.

http://www.corel.com/corel/product/index.jsp?pid=prod4670071

Here's a webinar that goes into many of it's features that I'd suggest watching so you can get a better idea of what to look for when using it (as it's very full featured software):

It's very fast, with versions available for Linux, Windows and OS X (and scales very nicely as more CPU cores are available).

I actually installed Lightroom 5 and it wasn't better if not worse! So, no luck with that

I assume the issues are not because of previews because it doesn't matter what I have tried 1:1 and there's no improvement.

I will give "no lens correction" a try but it's still a compromise because I have to do it again at some point.

Thanks for the suggestions!

Thanks Jim. I agree with you and that's what bothers me a lot; lack of performance consistency. It makes it very difficult to track what exactly is causing the problem.

I mentioned that LR5 wasn't any better but I am giving AfterShot a try. I hope it well supports my D600
