eyefinity with 720p

[DefDan]

im am using 720p projectors, the ati card finds them with name, setting up a group is no problem too - but not with the right resolution. i only can choose 5760x1080 and 3 other totaly worthless resolutions (not even the right aspect ratio). so at the moment i have to use 3x full hd what cost me 50% performance and forces my projectors to downscale what makes the picture even worse.
i tried the EDID method but that doesnt work at windows7 64bit at all, becouse my windows doesnt accept inf files made with moninfo. even when i use the phoenix tool to read out my registry data and make a inf from that it gets rejected... so "solved" is maybe not realy the right description for that topic....

for me eyefinity is a big disappointment, how the hell can u make such a feature and than screw it totaly with resolution castration....

if anybody has an idea how to work around on windows 7 64bit i would be more than thankful.

Sorry to hear you're having problems. A lot of us have been there. :( That being said, I also have Win 7 64 bit and did not have trouble with moninfo or phoenix. As far as I know, a 720p resolution is not currently supported, but if I had to guess I would say that in the future it will be avaliable. As of right now, the EDID mask is the route you need to go. I personally couldn't tell you what to do to fix it, but maybe someone here knows why the programs are not working for you. Maybe you can be more specific on what errors you are getting with those programs?

when i dont use the monitors as group (only cloned or expanded desktop) they work perfectly with 1280x720. only in a group i am limited to 3x 1920x1080.

my problem with the edid routine is at the last step. when i want windows to install the custom inf file as a driver i get an error from windows. i am told there would be "no driver in the folder, and if there is a driver i have to make shure it is for 64bit".
like i wrote even when i read out my registry and convert it to a inf without any modification i get that error.

sorry for my english ;)

i will upload my monitor data and custom file later on, maybe someone can make a look at it...

here are my files

like i said, when i make inf files with moninfo windows7 64bit doesnt accept them as proper driver for my monitors.

[DefDan]

no one with an idea here ? ;)

Hi I can't download the file from rapidshare because its overloaded at the moment... I hate rapdishare :lol:

I was able to install my modified .inf on windows 7 x64. It could be some sort of restriction that applies to projectors and not monitors though.

How did you try to install the inf?

The way I do it is going to device manager then monitors right click over the first display / update driver software / Browse computer for driver software / Let me pick from a list of device drivers / Have disk / Browse to inf / Select to install even though its not digitally signed / repeat process for 2nd and 3rd display/ restart PC.

[DefDan]

i tried it over "screenresolution"-"advanced"-"properties" etc.

your way aactually worked!

but not as i hoped. now one screen has no curser and one screen doesnt show up on windows start at all, only 1 is working now....

[Sideeffect]

Can you explain in more detail what you see now. Including the resolutions and refresh rates of the two monitors that show a display.

How are the projectors connected to the card? Are you using any adapters? What GPU are you using? What ATI driver version? What are the available resolution options in CCC after you applied the modified EDID?

[DefDan]

5870 lcs.
10.1 driver (no hotfix)

one is connected via hdmi (no cursor), one via dhvi-hdmi adapter (ok), one via displayport-vga adapter (this is the one that cant be found anymore).

hdtv resolutions available are 720p & 1080p @60hz but in my edid file was no 1080p.

[Sideeffect]

With the original EDID where you able to get the display working with the displayport to vga adapter using 720p? Did you try switching between duplicate and extended mode for the 2nd projector to see if the cursor appears? Can you create an eyefinity group using just the two projectors of 2560 x 720?

When you made the EDID did you create a new one or modify an existing one? Can you upload the dat files to another sharing site because rapidshare still wont let me get them.

[DefDan]

i made a new edid file.

when i didnt use the monitors as group (only cloned or expanded desktop) they worked perfectly with 1280x720. only in a group i was limited to 3x 1920x1080.

my main problem now is how to get back to the status before ;)

im trying to upload the files later.

You can just uninstall the monitor drivers using device manager to revert back to your previous setup. The driver is not digitally signed so windows will revert to one that is or the default supplied with the operating system.

[DefDan]

i tried that, but when i restart my pc the one at dp-vga port still remains dark and the other one has now cursor.

as the one with dp-vga doesnt appear there is no way to uninstall, why the curser stays away is a miracle to me.

[Sideeffect]

The dp - vga projector no longer appears in device manager?

Did you try reconnecting it to the displayport while the operating system is active?

It is possible to remove the registry information for the EDID using Monitor Asset Manager looking under Display ID's for your modified EDID name string and click view and registry then deleting the Key but I would check your connections first.

i attached an 19" tft for testing with dvi-vga adapter (tft has only vga input).

it runs fine at his nativ solution, however as soon as i insert the dp-vga adapter now the curser on my tft disapears. and no, the projector with the dp-vga adapter doesnt apear in the device manager when i connect it.

i tried to reinstall windos7 but my raid controller driver gets rejected every time now (same files i did setup the system 1 month ago, same usb stick) ... i dont think it is connected to my problems with the ati card but at the moment im realy screwed...

[Sideeffect]

I would uninstall the ATI driver 10.1. Download driver sweeper http://www.guru3d.com/category/driversweeper/ Restart and go into safemode and run driver sweeper and remove ATI files found. Go back into normal mode and install 8.703 driver http://forums.guru3d.com/showthread.php?t=315404 which is based on 10.2 and is a solid driver.

The act of uninstalling the display driver also has the benifit of reseting the displays and will revert you back to the original EDID. Reinstalling windows shouldnt be required.

[DefDan]

i will try that ;)

[DefDan]

ok i am back where i was.

3x1 with 1080p. i had to connect diconnect them whil running windows several times and finaly all 3 where working at the same time... man what a mess this stuff is ;)

[DefDan]

one restart later my dp-vga projector was gone again, another restart later my curser too.

i also tried it with 10.1 again after deinstalling and cleaning with driver sweeper, but the same happens.

awesome feature that eyefinity stuff ;)


------

finaly its working again. i had to make a fresh win7 installation.

thats it for me with eyefinity, i will try to get a matrox triple head for 720p and sell the 5870.

When I first ran eyefinity I had the missing curcur as well.
With my three monitor setup such as 1-2-3 the cursur would not appear on 1 that was the monitor with the windows start buttun so obiviosly yhat was a problem.

What I found was if I moved the cursur from 3 to 2 to 1 it would dissapear when it got to 1.

However if I moved the cursur from 2 to 3 and kept moving in that direction it would reapear on 1.

Try that and see if it works. After I did that I recreated a group using that method to make the mouse cursur work on all three.
