I am currently experiencing the same problem. I just updated to the Davinci Resolve 16 yesterday and this happened.

The photo shows the two black displays where I can't see the preview of any videos !

Attached in this link is the .NFO file and the Resolve log file: https://we.tl/t-hBpRClguku

Remove the display from the onboard video connector. If you want both displays, connect them both to the GTX1050Ti.

Can't I leave the monitors connected to the computer as is?

I currently can't connect both monitors to the GPU, thus can I leave as is and still get a preview for my edit?

If not this is very sad news as this was available in Davinci Resolve 15.

Thanks

I am having the same issue as Albertocv above. When I drag the video to the timeline, the video flashes for an instant in the preview window but then goes black. When I play, I hear the audio, but can't see preview video.

My System Information is attached. You'll note that I have two screens connected to the motherboard, one to the video card. Regardless of which screen I try the preview in, it doesn't work.

Uninstalled and reinstalled Davinci.

Moved ALL monitor cables to my graphics card, and restarted computer.

We can't help without information from your system.

We need a Resolve log file and a Windows System Information .NFO file.

Details here:

Hi,

Same problem here, but an odd setup: 2011 MacBook Pro 17" (integrated Intel HD Graphics 3000 & discreet AMD Radeon HD 6770M GPUs).

I'd like to use the MacBook Pro 17" screen, and an external nVidia (vGeForce GTX 1070) Sonnet eGPU Breakaway for CUDA processing through Thunderbolt 1/2 to Thunderbolt 3 Apple adapter. Installed both: https://github.com/mayankk2308/purge-wrangler; https://github.com/mayankk2308/set-egpu.

Using the latest nVidia web driver 440.89 (GPU Driver Version: 387.10.10.10.40.133). nVidia eGPU works great on other apps. But Resolve does not show clip in preview window with nVidia eGPU selected in Resolve GPU preferences panel. However, if the MacBook Pro 17 is connected to an external monitor through the Thunderbolt port (removing the eGPU option), then Resolve uses the discreet AMD Radeon HD 6770M and DOES playback in preview window.

Bottom line request: can Resolve use the eGPU while running the preview through internal screen.

Thanks,
Chris

I can’t imagine how a TB 3 GPU can work on a TB 1 connection to a 2011 computer. I’d recommend a computer made in the last couple of years and current OS. Sorry to bring bad but realistic news.

Thanks for taking a look at my post. Well, please do try imagine : OSX 10.13.6 is the last OS to support CUDA. As for the Mac, it works OK. There's no power-user here, so TB3 to TB1 bandwidth is OK on very lo-res footage. Just need a stable environment to write OFX Resolve plugins. I was wondering if Resolve preview panel might work if an external monitor were connected to the nVidia directly.

Perhaps there's a alternative forum better suited to my queries?

Thanks,

The ASUS manual for your GL704GV has no detailed info on the available BIOS settings.

Look in the Advanced area of the BIOS for something related to Internal Graphics mode, and set it to IGFX instead of PEG/PCI, or something like that.

And/or, if you have an external display connected, what happens if you remove that?

Hi,

Still doenst work. Opened up my Advance Area of BIOS but cant find anything in the internal Graphics mode to change the setting. Am I missing something?

I've attached my latest Log if it helps.

Seems like the video shows when its in Fusion / Fairlight but not in the editing areas.

Please help .. thanks

@Taiaha: You have a very old NVIDIA driver installed.

Likely the reason the driver links you tried failed, is because they are for current 10 and 20 series GeForce cards. You have a 750Ti card, so you need to install the current driver for that and see how that works.

Go to the NVIDIA Driver Download site and enter the info your GPU, and install that driver.

If you still have issues, send another NFO file, along with a Resolve log file.

Download Resolve Studio 16.2 again and install it. You don't need to uninstall the current version.

You currently have build 054 and the current build is 055.

I don't think it will have an effect on your issue, but we need to start with that.

If it still has issues, send another Resolve log, as well as a Windows System Information .NFO file.

Hello Dwaine,
As you can see in the screen shot, windows explorer shows braw thumbnails, but not Resolve.
Premiere plays them properly too.
I have attached suggested files.

Is the issue only with BRAW files? Do other file types work?

If you put a SMPTE Color Bar Generator on a timeline in the Edit page, and make that clip a Compound clip, do you see that in the viewer?

You've got a very old (2017) GPU driver installed.

Have a look at this link:

I have a Radeon RX 5700 XT video card. Nvidia drivers at not going to help..

I am an Adobe Premier Pro user keen to try out Resolve.. I have just run it for the first time today, and THIS issue appeared. Yikes.

That finally did the trick!
Initially i uninstalled and tried previous versions, with no results either,
but the moment i disabled open cl all media showed up.
So it seems resolve does not work with Intel GPU as stated, and only in CPU mode.
