Windows 7: Reset Dual Monitors

Reset Dual Monitors

I have moved this post from the graphics card forum.

I have an HTPC with a monitor attached to it via a VGA connection. I also have an HDMI cable attaching a second monitor in another room. Somehow, I changed the primary monitor to the one in the other room. Now I cannot see my desktop on the monitor next to the PC and thus cannot navigate. I cannot control the PC while looking at the other monitor (primary) in the other room.

The only way I can get my desktop back on the monitor next to the PC is to unplug the HDMI cable to the primary. However when I plug it back in, I lose the desktop again as the other monitor still thinks it is the primary (when it is plugged in).

I don't know how to reset this. What makes it difficult is that I believe I need to reset it while both monitors are plugged in. However I cannot control the PC when both are plugged in.

How do I fix this?

can you flip through the projector menu using
+P

or whatever your keyboard might be setup for as a way to toggle the displays

For instance on my keyboard there is a "moniter" symbol in a box on the f4 key looks kinda like |[]| before the box that i mentioned which simply means to use the [fn] function key, and it similarlly toggles through the same menu

not sure on a HTPC but this allows single-moniter#1, dual-duplicate, dual-desktop(the mode you seem to be in)and single-moniter#2

I not I can think of two possible other ways, then a last resort, thats a pain. hopefully this will work

My keyboard does not have those functions. It is a simple logitch keyboard. My screen is blank with a windows logo but no desktop icons. I could try to pick up a blue tooth keyboard and try to navitiate the deskptop in the other room with the other monitor which has visibility to the desktop.

Thanks

okay how did you switch the primary with the secondary initially. What window, your graphics software or windows screen resolution window?

great!

I was going to tell you (for future advice)

try: +R :to bring up the run menu, then you can run any program you need.


CONGRATS!

One last question. Could this also be rectified if the HTPC monitor was able to do 1080p? That is, the problem seems to occur when I extend the desktop monitor (MAIN) and the monitor on the end of the HDMI resets to the resolution of the HTPC monitor. If I replace the HTPC monitor with a new one will this fix the problem too?

I only have one HDMI out from my graphics card (AMD HD6750). This feeds my 1080p monitor in my other room. The only other outs from this card are a VGA and a funny looking ouput which I am assuming is a DVI (I think that is what that is called). The idea here is that I want 1080p on both monitors but need to get the 1080p signal from my grahics card to the new monitor by not using the HDMI out (i.e. the other ouputs).

I dont believe there is any way to do that.

(maybe someone knows some clevar way to "trick" the device into believing it's displaying at a resolution/speed/method that it is not? I doubt it.)

and youre just trying to make you computer monitor display at 1080p so that it will match the HT screen rez - instead of having the HT screen "pulled-down" to whatever the computer moniter is displaying at? correct?

have you tryed using the Catalist Control Cntr to create the 1080p for the main HT large screen while creating a group of settings that can be displayed by your other computer monitor?


it may be under: dig.flat pannels >> HDTV support (although i don't have it in front of me)
