For lightroom, simulate second screen functionality with Chromecast SDK

Although Chromecast can currently "mirror" screens, wirelessly, it can't extend a desktop right now (and there would be technical limitations even if it did), having Lightroom simply cast the image and functionality to chromecast would be pretty ideal. The FIT image would be on the main screen with all the controls, the FILLED or 1:1 image would be on the casted screen and move around based on where the cursor is over the image on the main screen, just like how the lightroom second monitor functionality already works

Indeed, the equivalent functionality with a mac transmitting to an appleTV using airplay is extremely useful.

To be able to do that with a chromecast, instead of carting around an appleTV, would be part of a lightweight display and marketing system that would really speed things up. Might also allow multiple macs to easily send to multiple TV's in a venue without changing wiring, or needing to pick up the remote control of the TV's.

I want to third this one. I can use Chromecast by casting the whole screen through the Chrome Browser, but it would be nice if LR could hook it directly.

Yes to clarify with Mike, casting the whole screen through the Chrome Browser is only a mirror image, whereas I am requesting to simulate Lightroom's "Secondary Display" options with Chromecast registering in Lightroom as a secondary display option or simply being used as one.

This would require native Lightroom integration or via plugin, but it seems this isn't an option for developers just yet. So I just need to request it publicly.

I am computer illiterate so I need some help.
Purchased Chromecast in order to show images from Lightroom on my HP computer to my Samsung TV. I am able to display some items - such as the Weather Channel from one to the other. How do I display photos in Lightroom to the TV??? Thanks so much.

I also own Photoshop on a laptop so I guess the same question applies to that as well.

Hey GW Pridgeon,
This is the tutorial I found my info at. I used the second link - How to stream full desktop. You have to start in your Chrome browser and click as if you were going to send the browser tab to the Chromecast. What I had not seen before is that there is now a little triangle to the right of the dropdown for the Chromecast. You have to click in here BEFORE you "click send to Chromecast". This will give you the option to send the full screen. Click that, then click to send it to the Chromecast. You will be given a pop up box that makes sure you want to send the whole screen. Click yes and you are good. There is about a 2-3 second lag while casting. The nice thing is that you can still use your mouse to highlight things and point out things. The feature is in beta, and should be treated as such, but I have had no problems. Watching video this way is not fun as it is very stuttery, so if you have something in video to show, use an HDMI cable. Hope this helps.

Oh, btw, you need to add the Google Cast extension to your Chrome Browser prior to doing the above or none of that will work. Sorry, just thought of that.

I think this is a really good idea! Chromecast is a very inexpensive device that produces images onto my 1080p display. It's always a good idea to look at your photos on 2 monitor sources.

I really hope adobe develops a chromecast plugin for this!

Some other items that could be displayed are:
Histogram
Preview
Before/after
Slideshow
metadata overlay
etc

Does anyone succeed in using TV as second screen of LR (PC) with a chromecast dongle ?
I load a "Plex server" on my PC but:
1) I don't find any SDK for LR
2) I don't know how to simulate second screen functionality with Chromecast SDK
Thank's in advance for your help.
