Lightroom and second display

Hi, I'm sure its been asked many times before, but is light room capable of using dual display on a mac? if so, how?

Not directly, although some users report success splitting the application across monitors so that the right pane containing the develop controls is on the secondary monitor.

IMac and second display help.

I am currently thinking about getting a second display for my iMac.
Because my iMac is only 17" i need a bigger screen.
I have 3 questions-
1. Can i use my imac as the second display and have my new display as the main screen displaying the menubar and dock?
2. Are there any monitors other than the apple displays that look really good with the imacs?
3. With an intel graphics card is there a maximum screen size it can cope with?
Cheers

Lightroom and photoshop display colours differently??

I have just done a colour critical shoot of fashion garments. There is a dramatic difference particularly noticeable in Purple colours between Lightroom and Bridge. Lightroom displays it as blue and Bridge displays it correctly. I cannot figure out why this is - it means that I cannot work in Lightroom as I am not sure if the colour is correct or not.
Please - if anyone can shed some light on this I will be eternally grateful.
By the way I work on a mac with CS3 and the latest lightroom - on a calibrated system so it is not a calibration issue.

Are you sure that bridge is actually generating previews from the RAW and that you are not just looking at the camera-generated jpeg preview embedded in the RAW? This is pretty typical for bridge to do. The camera-generated preview generally looks very different color-wise from Lightroom and ACR because the camera manufacturer. Test this by double-clicking the RAW in bridge. Usually the color will be quite different from the preview you see in Bridge. After you close ACR, the preview will get updated in Bridge too. The reason behind this color difference is that camera manufacturers use secret, proprietary algorithms to determine the color from the camera's raw sensor data. This color is not necessarily correct, but what they consider "pleasing." If you shoot RAW, your RAW converter supplies its own interpretation of the data. Usually based on shooting color patches with the same camera.

Adobe lightroom and 2 display support

Hi,
I would like to use lightroom, but...
I currently use 2 displays to work in (for example) Photoshop. I just put all my toolboxes on my rightside display and my image on my left display.
Does lightroom support this to?
Can I put the toolbars on another screen?
Is it possible to show the slideshow on the second screen?
Thnx!
Kwinten

hello,
it would be nice that when a two monitor set up is introduced( V1.5, V2 or when/ever), that it would allow for different modules to be open in a new window, and dragged to the second monitor.
...this way one could have the develop module open on the primary monitor, and the library open on the secondary monitor. ( or print module and library )
This would also be nice in the case of third party modules.
However, I think it is not a deal breaker, LR works very well on a single monitor, the two monitor thing is more a need with photoshop, because it can get pretty cluttered.
thanks,
Fabio

New iMacs and second display

I'm looking at getting a new 20" iMac and looking at both versions. My main concern is that I already have an older Apple 20" cinema display (the kind with 2 plastic legs) that I want to hook up as a second, extended desktop monitor.
The first iMac has an ATI Radeon HD 2400 XT with 128MB memory. Can this run a second 20" display or will there be significant slowdown?
The more expensive iMac has an ATI Radeon HD 2600 PRO with 256MB memory. Clearly this is better with more memory but will there be a huge difference that I would notice in every day use, enough to warrant the extra cost?
I don't do any videos or 3d rendering, I work in Photoshop and Illustrator a lot on 2d graphics, sometimes pretty large but hardly ever over 200 MB.

I have the 24" imac intel duo 2.4, tried running my apple ADC 15" via the ADC to DVI converter that I used to use on my G5. The converter is more or less a power supply but it requires that you plug into a computer USB (not on a hub, even a powered one) port. This started making the imac act wierd and during a disk verification, it came up with several USBF errors, locked up a few times with the spinning beach ball. I disconnected the display and usb plug and everything works just fine. I also have a ADC 20" cinema that has superb color and is the closest thing to the press we print on. Even tho I try to do things by the numbers, it's nice to have a calibrated screen and the new imacs (even with custom profile) is still off. I'm sad that I won't be able to have the extended desktop until i either buy a dvi version or a new 20 from apple ($500 refurb). Anyone have any experience using the converter successfully?

MBP Retina and Second Display issues

I'm using a Macbook Pro with retina display and having a hard time really understanding how it translates to a normal 72dpi screen, so I hooked up a second computer, this is what photoshop looks like on it...
Suggestions?

Disable GPU drawing in Photoshop's preferences, and let Apple know about their video driver problems.

Windows 10: Second display "turns off" in lock screen

Unfortunately some of these quirks are why people don't upgrade straight away, on the plus side by having over 14M people upgrade in less than 2 days MS now has a lot of faults found and fixes to work on - quickly. We hope.
That said I have a dual screen setup and my monitors retain the screen space settings.
The fact yours is a laptop maybe indicative of your issue - does your laptop have dual graphics, e.g. one for high use games and one for low use 2D?
Does it turn off 3D settings - it may not be a Windows 10 thing but more of a setting that has defaulted.

I don't recall having this problem with Win 7 Pro, just upgraded to 10 pro a few days ago.I have an HP Probook 450 G2 (with up-to-date graphics driver) and a dual monitor setup. Main display is on HDMI and second display is on VGA. When I lock my laptop (Win+L), it seems to "turn off" the second display and shifts any applications I had in the second display to the main display.While a relatively small issue, it is rather annoying to have to drag applications back over to the second display when I resume working.It doesn't seem to happen right away though, nor does it seem to trigger when display is set to sleep at 20 minutes. I'm not sure how else to explain this. I've found posts of a similar nature on Spiceworks and other forums, but nothing seems to help.Thispostis from a while ago and is related to Win 7, but does seem to describe...

24" imac with second display that flickers on and off randomly

Hi, I'm a n00b here, I've read a handful of threads before posting this a I cant seem to find a definitive answer.
I have a 24" 2.4Ghz aluminium iMac and I've recently purchased a HP zr24w 24" IPS panel as a second display, connected with an apple miniDVI - DVI connector.
The screen flickers off, to totaly black every time the mac seems to be having a hard time doing something, be it fast scrolling, flash video, but someimes randomly.
I have boot camp installed with winblows vista (for work) the screen does EXACTLY the same thing, all be it less frequently. This for me rules out the Mac OS, i think it must be something video card/driver related.
Was there ever a fix for this? most of the threads seem to just die with no official answer, it would appear that MBP users were ok until the last 10.6.3 update, when the problem seems to have returned, although i think thats a different issue with the same net effect.
I have spoken to apple care and the very helpful girl I spoke to send me some logging software which I've run and sent the logs back, that may help them out someway.
Any help would be GREAT !!
many thanks
Michael

well, some time has passed, here's where I'm at so far.
I tried a friend's samsung 24" screen and all was good with the world, no flickering on and off, no black outs nothing, for days it was all fine. I swapped the HP monitor back on and it went right back to its old ways. I called HP tech support, they decided that the monitor was faulty, i returned it to where I got it from and they have sent me a new one. Which was fine, for about 7 hours!!
So, to recap, the mini-DVI to DVI adapter is fine as it worked on the samsung screen, the HP screen is brand new and exhibiting the exact same issue as the first one (cant be 2 faulty ones surely) The samsung screen was fine.
This leads me to think that there is some compatibility issue between the 24" imac and this particular (hp zr24w) monitor.
I have followed apple support's requests for data logging but they cant find anything wrong there.
I'm out of ideas, any help would be GREATLY appreciated !!!
thanks
Michael

Hi, I use BootCamp for my windows 7, I have a Macbook Pro 2012, and I want to use a second display, is this possible with my Mac using Windows?

I just dont see a port usable for a second screen. I want to hook it up to my TV to view photos and movies. What can I do?

What do you mean you don't see a port? Does your computer have a HDMI or a ThunderBolt/Mini Display port? You can use these to add a second display. Which one you use depends on what input ports your tv has.

Why does Lightroom (and Photoshop) use AdobeRGB and/or ProPhoto RGB as default color spaces, when most monitors are standard gamut (sRGB) and cannot display the benefits of those wider gamuts?

I've asked this in a couple other places online as I try to wrap my head around color management, but the answer continues to elude me. That, or I've had it explained and I just didn't comprehend. So I continue. My confusion is this: everywhere it seems, experts and gurus and teachers and generally good, kind people of knowledge claim the benefits (in most instances, though not all) of working in AdobeRGB and ProPhoto RGB. And yet nobody seems to mention that the majority of people - including presumably many of those championing the wider gamut color spaces - are working on standard gamut displays. And to my mind, this is a huge oversight. What it means is, at best, those working this way are seeing nothing different than photos edited/output in sRGB, because [fortunately] the photos they took didn't include colors that exceeded sRGB's real estate. But at worst, they're editing blind, and probably messing up their work. That landscape they shot with all those lush greens that sRGB can't handle? Well, if they're working in AdobeRGB on a standard gamut display, they can't see those greens either. So, as I understand it, the color managed software is going to algorithmically reign in that wild green and bring it down to sRGB's turf (and this I believe is where relative and perceptual rendering intents come into play), and give them the best approximation, within the display's gamut capabilities. But now this person is editing thinking they're in AdobeRGB, thinking that green is AdobeRGB's green, but it's not. So any changes they make to this image, they're making to an image that's displaying to their eyes as sRGB, even if the color space is, technically, AdobeRGB. So they save, output this image as an AdobeRGB file, unaware that [they] altered it seeing inaccurate color. The person who opens this file on a wide gamut monitor, in the appropriate (wide gamut) color space, is now going to see this image "accurately" for the first time. Only it was edited by someone who hadn't seen it accurately. So who know what it looks like. And if the person who edited it is there, they'd be like, "wait, that's not what I sent you!"
Am I wrong? I feel like I'm in the Twilight Zone. I shoot everything RAW, and I someday would love to see these photos opened up in a nice, big color space. And since they're RAW, I will, and probably not too far in the future. But right now I export everything to sRGB, because - internet standards aside - I don't know anybody who I'd share my photos with, who has a wide gamut monitor. I mean, as far as I know, most standard gamut monitors can't even display 100% sRGB! I just bought a really nice QHD display marketed toward design and photography professionals, and I don't think it's 100. I thought of getting the wide gamut version, but was advised to stay away because so much of my day-to-day usage would be with things that didn't utilize those gamuts, and generally speaking, my colors would be off. So I went with the standard gamut, like 99% of everybody else.
So what should I do? As it is, I have my Photoshop color space set to sRGB. I just read that Lightroom as its default uses ProPhoto in the Develop module, and AdobeRGB in the Library (for previews and such).
Thanks for any help!
Michael

Okay. Going bigger is better, do so when you can (in 16-bit). Darn, those TIFs are big though. So, ideally, one really doesn't want to take the picture to Photoshop until one has to, right? Because as long as it's in LR, it's going to be a comparatively small file (a dozen or two MBs vs say 150 as a TIF). And doesn't LR's develop module use the same 'engine' or something, as ACR plug-in? So if your adjustments are basic, able to be done in either LR Develop, or PS ACR, all things being equal, choose to stay in LR?

PS RGB Workspace: ProPhotoRGB and I convert any 8-bit documents to 16-bit before doing any adjustments.
Why does one convert 8-bit pics to 16-bit? Not sure if this is an apt comparison, but it seems to me that that's kind of like upscaling, in video. Which I've always taken to mean adding redundant information to a file so that it 'fits' the larger canvas, but to no material improvement. In the case of video, I think I'd rather watch a 1080p movie on an HD (1080) screen (here I go again with my pixel-to-pixel prejudice), than watch a 1080p movie on a 4K TV, upscaled. But I'm ready to be wrong here, too. Maybe there would be no discernible difference? Maybe even though the source material were 1080p, I could still sit closer to the 4K TV, because of the smaller and more densely packed array of pixels. Or maybe I only get that benefit when it's a 4K picture on a 4K screen? Anyway, this is probably a different can of worms. I'm assuming that in the case of photo editing, converting from 8 to 16-bit allows one more room to work before bad things start to happen?
I'm recent to Lightroom and still in the process of organizing from Aperture. Being forced to "this is your life" through all the years (I don't recommend!), I realize probably all of my pictures older than 7 years ago are jpeg, and probably low-fi at that. I'm wondering how I should handle them, if and when I do. I'm noting your settings, ssprengel.
ssprengel Apr 28, 2015 9:40 PM
I save my PS intermediate or final master copy of my work as a 16-bit TIF still in the ProPhotoRGB, and only when I'm ready to share the image do I convert to sRGB then 8-bits, in that order, then do File / Save As: Format=JPG.
Part of the same question, I guess - why convert back to 8-bits? Is it for the recipient? Do some machines not read 16-bit? Something else?
For those of you working in these larger color spaces and not working with a wide gamut display, I'd love to know if there are any reasons you choose not to. Because I guess my biggest concern in all of this has been tied to what we're potentially losing by not seeing the breadth of the color space we work in represented while making value adjustments to our images. Based on what several have said here, it seems that the instances when our displays are unable to represent something as intended are infrequent, and when they do arise, they're usually not extreme.

With 8 bits, there are 256 possible values. If you use those 8 bits to cover a wider range of colours, then the difference between two adjacent values - between 100 and 101, say - is a larger difference in colour. With ProPhoto RGB in 8-bits there is a chance that this is visible, so a smooth colour wedge might look like a staircase. Hence ProPhoto RGB files might need to be kept as 16-bit TIFs, which of course are much, much bigger than 8-bit jpegs.
Over the course of my 'studies' I came across a side-by-side comparison of either two color spaces and how they handled value gradations, or 8-bit vs 16-bit in the same color space. One was a very smooth gradient, and the other was more like a series of columns, or as you say, a staircase. Maybe it was comparing sRGB with AdobeRGB, both as 8-bit. And how they handled the same "section" of value change. They're both working with 256 choices, right? So there might be some instances where, in 8-bit, the (numerically) same segment of values is smoother in sRGB than in AdobeRGB, no? Because of the example Simon illustrated above?
Oh, also -- in my Lumix LX100 the options for color space are sRGB or AdobeRGB. Am I correct to say that when I'm shooting RAW, these are irrelevant or ignored? I know there are instances (certain camera effects) where the camera forces the shot as a jpeg, and usually in that instance I believe it will be forced sRGB.
Thanks again. I think it's time to change some settings..

When I connect a second display both displays start to cycle on and off.

I am connecting a second display that works on both my macbook and macbook pro. When I connect it to my imac, both monitors start blinking on and off.
Any ideas?
Thanks

Long story short I solved the problem, and it was totally a model issue. It is the HP w2207, which apparently has a problem with iMac 24 inch, the nvidia graphics card, mini DVi to DVI and 10.4 in particular. You see these two devices, just don't get along very well. The imac tries to auto set the monitor at one resolutions and the monitor tries to auto set itself at another, and they will continue to do this indefinitely. However both when I switched to a VGA cable, which I believe prevents the monitor from auto setting itself, and when I upgraded to 10.5 solved the problem.
Personally I didn't mind the upgrade, as I was planning to do it anyway, and is definitely the better solution as there is noticeable difference in the color between the two cables.
Anyway thanks for the help everyone.

My MacBook Pro display won't work without a second display plugged in. What caused this, and how do I fix it?

I'm using a Dynex Mini DisplayPort to DVI Adaptor to use a second display (an older display, I'll admit). After I have unplugged the adaptor, my MacBook still tries to read the second display, and switches back-and-forth between a blue screen & my desktop. It stabilizes once I plug the adaptor back in. What is causing this problem, and how do I fix it so I can use my primary display without having the adaptor constantly plugged in?

Reset PRAM.

If not try Reset SMC.

Second Display flashing on and off randomly

Since upgrading to Lion, my second display (ViewSonic VX2235wm) flashes on and off frequently. There doesn't seem to be any pattern to it. Has anyone else experienced this behavior? This problem is with a second display hooked to my 2.4 GHz Core 2 Duo iMac. It's driving me nuts!

I've since tried other resolutions and haven't found any others that are stable. I've used the monitor with another system and had no problems and the problem started immediately after the Lion install, so the issue is clearly Lion-related.
I haven't heard of many people having this issue, so I'm contemplating upgrading the monitor to get around it. (Longterm, the 1360x768 solution is unacceptable to me as it stretches the image.) I think it may be specific to a few makes/models of monitors and possibly even to a graphics chip/monitor combo. I think if it were more general, there would be more noise about it: a two monitor set-up isn't uncommon.

Change display order between second and third display

I have a MacBook Pro Retina 15" (2012) with 2 external displays (Dell 27 and Samsung 24). I use the Dell as main display. My problem is with FCPX. I want to use my Samsung 24 as Second Display to see my video material in it with the option "Show events in second display", but OSX set the macbook display as second and the samsung as third. So, I only can see the events in the macbook and the timeline in the Dell. (Unless I close the Macbook. losing one display. I'd rather keep the 3 to use one of them (macbook) with a Finder window).
Anyone can help me with this or is impossible to change teh order between the macbook display and the Samsung 24?
OS X Yosemite 10.10.3 / FCP X 10.1.4

Another way to put this: in my original instructions, do step 1 after steps 2 and 3:
(Start with FCP in single window mode, in whichever display, it does not matter)
2) 1) Open System Preferences->Displays, click on "Arrangement"
3) 2) Drag the visual representation of the Menu Bar to the display that you want to use as "second" display in FCP X.
1) Move FCP X's single window to the display you want to use as your main display.
4) In FCP X, choose to put the viewers events on second display.
