Resolume Forum

Sounds crazy but it is true. Or I am missing something..?

It is hard to find laptops with HDMI output that will be accepted by the Intensity Shuttle- USB3 or Thunderbolt.

90% of source laptops with act like they are connected- in resolution settings it lists that you are connected to BMD device, you can set the resolution to 720 or 1080- yet only a hand full of source laptops will actually show video in Media Express or Resolume. I know- check the settings in Media Express or Resolume- done, its always only 1080p 60 or 720p 60 that laptops can output via HDMI successfully to a Shuttle. I can input one laptop that works fine, shows video- then plug in a different one, same settings, laptop sees the BMD and resolution can be set, but no video shows.

I even took my laptop that I use the Shuttle with to the computer store, trying different laptops HDMI out and I have only found one Lenovo out of all the laptop that can get video to show through the Intensity Shuttles.

So far only these work:

Sager NP8130 / Clevo P151HM1 with a GTX 460M, Chipset: HM65 - Own this, works every time
Lenovo z50-75 AMD A-Series A10-7300, Radeon R6 - Works but not enough power
Old 2008 Macbook Pro with Nvidia Geforce 8600M GT - Old, but works


But every other laptop I could not get to show video.

Note: If using an Intensity Pro card installed on a desktop- It will accept any laptop as a source or even my ipad or iphone -- But this never works on the shuttles, very sad.

So am I totally missing something or what is the issue here? Is there any guideline I can get for what kind of laptops will work as a HDMI source for the Shuttles? Or does anyone have a list of laptops that DO work?

It probably has to do with laptops not having enough power on pin 18 [+5 V (max. 0.05 amp)].

A couple of thoughts:

• Have you tried with an HDMI amp?
  Do you notice any difference when the laptop is plugged or unplugged?

Interesting, I have not tried that. I do not have an amp.. But that could make since.. I did notice that one of the source laptops I was testing sending HDMI was working but would start to flicker when the CPU was under a heavy load, but I did not notice any difference when they were plugged in..

I think you are right. So what would be a way to figure out if the laptop will have enough power on the HDMI? I am shopping for a new one but it will most likely have to come in the mail and would be hard to test before buying.. Is there a spec, HDMI version or something I can look for?

...Did find it interesting that the Lenovo with a shared graphics card and super little power supply was the only one at he store that worked.. Do they all have a new version of HDMI with less power or something?
