Resolume Forum

HDMI doesn't have enough bandwidth to do 7680x1200 at 30hz so use a DisplayPort cable and you should be fine.

Thank you Oaktown, I hope to solve it! Tomorrow my cables arrive. Therefore it's the hdmi input that don't have enough bandwidth? Thank you for now. I've ordered the dp - dp 1.2 but even the 1.1 will work fine?

The display port 1.2 finally solved the problem, Thank you Oaktown. Now I'm having hard time to edit properly the f44. Resolume only see 1 Virtual, pc display and 1 screen 1280x720.

In wall designer
I select projector with native resolution 30 or 60hz?

Any step by step in this forum to set up 4 1920x1200 at 60hz so i can see 1 screen 7680 x 1200 or it's too much?

Any advice , my gig is in 12 hours

It sounds like you're not setting up your input size and resolution for the datapath Personally I would set up the datapath EDID to 3840 x 2400 at 60 Hz since you're using this with displayport and then and in Arena, You would assign your screen to the datapath and distribute four slices according to the grid you set up in wall designer which in this case would be 2x2.

I've followed what you recommended and the input said the source exceed the bandwith limit reduce resolution org refresh rate. Before the the projector input was 1280x720 at 142hz now is 1920x1200 60hz...but resolume see only 1280x720...Oaktown thank you for you help I hope you have some time to help me to solve the problem I'm very nervous...

After putting 30hz I see 1 screen 1920x 1080. But I still didn't test the slicing. Is this what should I see ? Or I should see 3840x2160... Which makes more sense to me.

Sorry, that was my bad! Since you're dealing with 1920x1200 projectors, you should set your datapath to be 3840x2400@30Hz. If that resolution is not available in Windows you may have to create it and once you've done that i would recommend you restart Arena. Also, make sure your display scale is set 100% in Windows.

...ok. Does have to be extend these display in windows, or different?
And what screen size should i expect? 3840x2160?

I still didn't plug the other hdmi-hdmi projector...

Yes you should expect 3840 x 2160 @ 30Hz in windows. And yes it should be an extended desktop. As I said if that resolution is not available when you're plugged to your datapath, create a custom resolution.

Custom resolution, in wall designer where? Input source? Or in devices, advanced timings, custom ... only resolution or other parameter matters?
