Best solution for PowerPoint on LED TV

BigA 770 207 March 1, 2011 at 07:26 PM
This is an odd question, but where I work we just got two Sony 46" LED TVs. One we are just going to set to CNBC, but the other we want to loop PowerPoint shows. We wil probably change them once a week. Both these TVs will be mounted and networked.

I have been thinking about a few ways to do this. The main problem is that the few users who will be doing this from week to week are not very IT savvy. I want to make it as simple as possible.

1) Run a mile long VGA cable and connect to a laptop/desktop we have in our server room
2) Save the PowerPoint shows as a video and save them to a DLNA NAS. Stream from the TV that way (this Sony TV has an option to loop videos)
3) Save the PowerPoint shows to a USB stick and connect the USB stick to the TV
4) Setup a separate desktop for DLNA and stream that way

Looking for other suggestions and feedback (good or bad).

Thanks,

A

USB stick sounds good to me, except that you probably have to manually start it playing every time the TV gets turned on.

Thanks, I think that is the best option too. I guess my work is worried that someone would steal the USB sticks. I don't think it's a big deal since we only need 2GB at most stick and who cares if someone took a 5 dollar USB drive. The data is not sensitve either.

These TVs will pretty much be on all the time during the day. I am pretty sure they have a sleep timer or mode that can be set on.

can the tv play back powerpoint files? or do they need to be converted to a movie format every time they're updated? that might be a little too much for the folks doing the updates to the slide shows. a video over ethernet solution (or wireless hdmi) + nettop running powerpoint viewer might be the easier way

I think USB is by far the easiest and most reliable way to go. Their documentation is built into the TV (i-Manual), but it is poor, so it will take some trial-and-error to get it to work. Some of the points:
  • Formats: AVCHD, MP4 (AVC).
  • Video files are located in the following folder structure (hierarchical position):
  • /AVCHD/BDMV/STREAM/00000.MTS/PRIVATE/AVCHD/BDMV/STREAM/00000.MTS
  • /MP_ROOT/100ANV01/MAHA0001.MP4
  • The TV has "USB Auto Start" settings available, which might launch the movie automatically, as soon as you turn on the TV.

The instructions seem a little complicated. I looked into it, and it's because the AVCHD format is like Blu-ray, and it is created by camcorders. The good side is that it offers very high quality, even 1080p30 resolution, just like Blu-ray. Once you find an encoder, and you put the files in the right places, it should work very well. Wikipedia has a good article on AVCHD [wikipedia.org], which explains where the files go, how they get named, etc.

I would have to convert it. I will just save the PowerPoint as JPG files. I can run the slideshow that way. The TV has quite a few options for running slideshows. It actually works out pretty well.

I have a desktop or laptop I can use. I am going to see if I can setup DLNA on it browse that way.

I think the JPG conversion from PPT would make the files look shitty. You would probably be better off creating a video from the PPT and having the TV play that.

Thanks, and yeah the instructions are terrible.

I guess when they want a high end PowerPoint I can create it and do it this way. I actually have a lifetime license to DVDFab and the video converter is pretty good.

Basically, what I am going doing is setup every type of option and see what works best.

Please let me know how it works for you. I have to do marketing work, too, and if you figure out how to get it working well at 1080p, I will probably try the same thing.

I tried it out, it actually works pretty good. These are just informational slides. Basically, all it's for is to display selling statistics and leader information.

We do the same thing in our company but I believe it's just a PPT on the secretary's (front desk) PC that she's responsible for. She sits about 10 feet from the monitor.

Could you get a cheap netbook or something and lock it down near the TV? This would give you flexibility to show essentially whatever you want on the TV.

Wont the USB port be up under the TV thus hard to see? Unless people know that its there they wont steal it. Then again it makes you wonder what kind of people you work with.

USB is the easiest to test and see how it works, its also the cheapest. I would start there.

Well, I was able to setup a desktop with media sharing and I am able to browse to videos and pictures. I like this way the best so far, but there are a few issues.

When you export PowerPoint slides as JPG it exports them 4:3. I don't think there is a way to export as 16:9. There is a way to edit the registry, but that will only change the DPI, so that doesn't help much at all. The jpg would be stretched a bit. I will have to see how it looks.

Only the text on the PowerPoints will change weekly, so I could technically create slides in Photoshop and have users edit the pictures. Maybe there is a light freeware photo editor I can find that will do that. That way I can create pictures in 1920X1080.

I am going to connect it to a desktop or laptop with VGA as well. It will be a long run, about 75ft and go to our server room. I am wondering what would happen if I connect the cable and then just use VNC, so the users can connect that way. Not sure how that would work.

laugh out loud they are driving me nuts. If somebody is out of the office for a few days they are lucky to come back without missing their network cable. Poor lady, the other day somebody took her phone handset cord and left an old crumpled up one.

Wow that is crude. Time to get some security cameras and stuff I guess.
