dissolve davinci not on screen

I've a editing problem, when I put between 2clips a dissolve during playing this clips the dissolve is black on the monitor.
Also when there are to many filters on the clip I see nothing.
After rendering as an AVI I see that the dissolve and filters are of course there.
My system is a i7-8700k, 16 GByte ram, for the moment no graphic card.
Is this perhaps the problem while I use the IGPU?

Thanks

You don't mention which GPU you have, but it could be the culprit.

Hi Uli,

"My system is a i7-8700k, 16 GByte ram, for the moment no graphic card."

I have for the moment no GPU, while until now I use Edius 8WG for editing and in this case no GPU is necessary.

Resolve needs a GPU for everything, it won't work without it.

You have a GPU. It just the GPU integrated in the 8700 CPU. The Intel 630. Integrated GPUs are fairly weak in the scheme of things. Make sure your video driver is up to date.

AFAIK, only the Intel Iris 4000 and 5000 work with Resolve (for HD without too many effects).

I will install a Nvidia-GTX1070 with 8GB, hoping this will work better and perhaps also put 16 GB extra.

That should help. But don't forget to deactivate the Intel graphics in your BIOS, on PC that can be a problem.

Thank you Uli,
This is bad then I need the iGPU for QuickSync in Edius Editing!
As you can see I've the Studio Version and I thought that in the setup you can make the choice which GPU for the UI and which one for calculation.

Thanks in advance

Just try it out, that problem doesn't happen on all machines. On the Mac it isn't even a problem.
