Displaying Video on Two PC Screens

I'm not sure if this will work but after dragging the window across the two screens, click on the Maximize button at the top right corner. I think that might lock it in and prevent it from resizing to the single screen.

I don't have a dual screen computer so I can't test it now. Let us know if it works.

Yes I have already tried that, and even after maximising the screen, it still reverts to the movie image on only one of the screens.

But thanks

Most of current mainboard can support two graphic card, so you can buy anthier display card and assemble on the board, then you can install another screen from it. windows support two cards.

but why do you split one picture into two parts? I dont think its a problem for the os.

I see on tv that usa bond exchange staff use such computer, and our musician can use up to 6 screen for their creating.

try to ask computer seller, they will show you all.

if you hope to use only two projectors, then you can use one socalled distributor to do the trick. you can buy it from rv seller, very cheaper.

I already have the "Hardware" is two separate video outouts. We use two screens all the time. Only ususlly one screen is the "Front of House" image, words for songs, a video, etc, and the other screen is the PC Users monitor with the control window for whatevet application we are running, Powerpoint, PowerDVD etc.

So normally we have different things shown on each screen. I also know that we can have the same image on each screen ie two copies of the same thing, but we want the impossible for nothing. :)

Its just for this occaison we want to run two data projectors to have a very big screen at the back of the stage as part of the backdrop for a special Christmas event. One projector would not have sufficient brightness to simply pull it further back fron the screen, and we also want it to be wide (ie 32x9. twice as wide as one 16x9 image).

Hence the attempt to run a video sequence with the one image shared across the two video uotputs.

But thanks for your thoughts.

Most dual display setups will allow you to resize the window across two screens, however the behavior varies among the different graphics vendors... I had the best luck using nVidia video cards for this, though the ATI FireMV works well also... your other option is to get a matrox DualHead2Go unit... http://shopmatrox.com/usa/products/datasheet.asp?ID=853 ... it makes the pc think it has one large high-resolution monitor connected.

Greetings,

I have been looking at doing the same thing myself.

As it turns out, the movie files have a set aspect ratio, I.E. the same resolution as a single monitor. The video cards give you a larger " Desktop" by adding more memory and addresses for the larger " Desktop". Some can be configured for monitors stacked or side by side.

I have seen a movie displayed on a four monitor setup, but the hardware was setup to do that even with the current 1280X1024 resolution files on a 5120X4096 Desktop.

ah, 4k is used for movies format. as I know. it may wonderful compare with pic on film.

Vulcan's link looks promising if you reverse the procedure and play with accelerator and rendering. Direct X capabilities may not allow this to happen the way we think it should. Gaming programmers can attest to that I am sure. ;)

a good link.

not bad. ga.

Thanks Guest & Vulcan, the DualHead2Go looks like a good unit, but I don't have time to try it this week. I'll give the Microsoft Solution a try tomorrow. I'll let you all know how it works.

you will need a vidio card with 2 out puts and it should work fine

I can sympathise with your problem. I use a dual screen desktop with a dual output card and find that applications are inconsistent in the way they behave in full screen mode, most fill the the display they are in, rather than the whole desktop.

One hardware solution is a device from Matrox that will split a single video output across two screens. This gets around the inconsistent behaviour of Windows but will cost several hundred dollars.

I would suggest asking this question on the more specialist forums that cover presentation AV and church AV as it is sure to have been answered before. Sites include:
