No Picture In Preview Screen

[jimstick]

I know this has been covered, but none of the solutions posted have worked for me, so here goes;

I have no picture on my computer preview screen while connected to a HD input. As long as I am connected to 480p I can see the preview. If the input is 720 or 1080 the screen goes blank. I can still record ok, but I can't preview. I am using HDMI input.

 

I know it has something to do with my computer, but I can't figure It out. I connected it to another computer, and it worked fine. It worked for a couple of months, and then just stopped. Nothing changed. My computer only has the onboard intel graphics, and I have not changed any settings, nor can I see how to. The only thing that changed around the time was several windows updates.

 

My computer is a Pentium 2.2 ghz, 4gigs RAM, 500gig HDD. Any ideas would be appreciated.

 

Thanks,

Jim

I solved my problem...sort of. If your computer has the Intel HD graphics built in, this might work for you, too. I had to disable the graphics hardware completely. I have to re-enable it to render the video.

 

I had to go into control panel; device manager; display adapter; right click; properties; disable device, and then I have picture in preview in all resolutions. However, that also makes the video captured kind of jerky, in other words, it freezes momentarily repeatedly. I think I can play with the bitrate and get it to smooth out.

 

The reason I say fixed sort of, is that, I did not have to do this before, and it worked with the display adapter enabled. I would still like to know why I have to do this, now, and not before. What changed? I can say for sure it was not the adapter settings. I have changed everything that can be changed, with no results.

Pretty sure it is your display settings on your PC...

 

Check the specs and set them to that

Didn't read the post too well. I said I don't see any way to change them.

If that is a single core CPU then it will not work correctly

 

 

Minimum System Requirements:

• Microsoft Windows® 8, 7, Vista™ SP2, XP (SP3 for 32 bit & SP2 for 64 bit), Intel® Core 2 Duo Processor 1.8 GHz or AMD Athlon x2 64 2.0 GHz, 2GB RAM
  
• Dual Core 2.3 GHz above is recommended for 1080 30p/60i recording.

It is dual core. As I said in my post,it worked before,and now it doesn't.

Something changed, and I didn't do it.
