I believe that means you're losing 5/48, which is 10.42%

I'm pretty sure not. Imagine your screen were actually 48x27 pixels, and you were trying to display a 48x32-pixel image. In each 32-pixel vertical column, 5 pixels would be missed out. So the reduction is 5/32. In those horizontal rows which appear at all, all 48 pixels appear.

Cropping a 3:2 image for a 16:9 screen is the same as cropping a 48:32 image for a 48:27 screen, so you're losing 5/32 or 15.6%. Likewise, cropping 3:2 for 4:3 is like cropping 9:6 to fit 8:6, so losing 1/9 or 11.1%. So 4:3 is better than 16:9 even for 3:2 originals.


For a 3:2 image on 16x9, the number I get is about 84% coverage (same as Peter).
For a 3:2 image on 4x3, my calculator says 88.8% coverage (same as Peter).

Excluding borders, title bars, and icons etc..

But I much prefer 16x9 for viewing photos, mostly because they tend to be larger screens for the same height/price as 4x3.

Yeah, you're right. I told you my brain wasn't working well.

I think the Norhtec MicroClient Jr., eBox-2300 (which is pretty much the same) or the decTOP all fit the bill

The supports VESA mounting and consumes 8 W. Mount it on the back of an LCD monitor and you are all set.


The problem is all these are companies out of Taiwan and shipping is $40-$50

What about the the $50000 to $100000 you will have to pay someone (or someones) to develop the software to run the frame?

There are, I'm sure, dozens of free RSS screensavers out there for both Windows and Linux.

I don't think it really fits the bill, as an LCD monitor doesn't look much like a photo frame, but, still, those are pretty cool.

Ok, with the screensaver route it's doable and passable in many instances. I got away with it making the Mac-based frame for my brother. But one really needs more specialized software if the frame is intended for someone who isn't computer savvy. My brother can easily connect to a share on the frame to copy images to it, or remote login using VNC to copy images off a connected USB drive. My parents on the other hand could never do that.

Using RSS would hopefully give the savvy admin the ability to set up photos remotely on a frame connected to a high speed internet connection, but truthfully, I haven't seen any great programs yet (ones that are great at the slideshow portion of the puzzle). Of course the last time I looked was earlier this year when making the original frame.

I set up a web-based photo upload (and captioning) engine for my frames without spending anywhere near $100,000 worth of my time.

Maybe I'm just a cheap date.

Granted, what I wrote isn't at all mass-market bullet-proof, and all my scattered family members are quite computer literate. So this proves nothing.
They'd be OK with getting it to work even if it were Comcastically bad. (or near-Microsoftian in its opacity)

Yet, I'd still say that my hardware is the weakest part of this equation (and I'm a hardware guy....)
because I hate having a spinning hard drive on this thing. And I hate that it's running Windows underneath.

I'd like to port it to Linux and have it boot off a USB flash drive and then run entirely in a RAM disk with no whirring spinning things and no writing to Flash (at least not for swap or tmpfiles, anyway).

Maybe someday.

Bringing this back to the top as it is a year on, things have changed and I'm in the market for one for the Mammy so she can fawn over picture of the grand-daughter she'll rarely get to see.

My needs are very similar to what Andy outlined in his first post, easy of use is very important, as I'm not in a position to pop over and debug issue.

I'd like to think that things have improved, but I bet they haven't. I did look at Kodak's new frames, they had made three changes:

- added a random order option
- added a stupid not-quite-touch screen (you touch on the border round the screen)
- removed the useful remote

and nothing else

I haven't look at any other new ones though, so who knows, things may have moved on.

Kodak also has (or is releasing) an OLED photo frame. Only $999.
