100% crash rate in VP18 with "Video Preview on External Monitor"

hambonio wrote on 8/3/2020, 7:43 PM

I am in Vegas Pro 18 Suite (284)

I can NOT get a preview on a secondary monitor. When I click on the button (or Alt+shift+4) the external monitor goes black, and VP18 crashes. It does not bring up a crash report either.

I have 3 total monitors. 3x Dell Ultrasharp U2718Q 27" 4K UHD. I can not get it to show on either of the other monitors when I change up the option.

If I try moving the VP18 main window to one of the other monitors, it also crashes.


Things I have tried:

I tried updating the graphics driver.

I switched from 8-bit full range and back to 8-bit video.

I tried a new installation of Windows and no other programs or plugins installed yet (I am sure I burned my 2nd registration for now on that one).

I have tried pulling files from both a brand new 1 day old 2TB M.2 Inland drive, and also a Samsung SSD Raid 0 configuration.

I have turned GPU acceleration off and on.

I jumped up and down in my chair.

I slammed my fist on the desk.

I bruised my pinky.

I regretted that decision and asked for forgiveness.


I tried VP17, VP14 and VP13 (all latest versions) and they all work. It is only happening in VP18.


My system:

VP18 build 284

Radeon VII (Driver currently is 27.20.2001.9003 and was 26.20.13025.10004 when I first tried).

3x Dell Ultrasharp U2718Q 27" 4K UHD Monitors

Ryzen 9 3900x,

Crosshair VII Hero, X570 Motherboard


Windows 10 Pro 1903 (currently back to that as I have everything installed on that build ) and I assume the clean OS install I did earlier was 2004 as I downloaded the fresh install from Microsoft today onto my flash drive.


Video files I have tried are from Sony a7sii and Sony a7rii. Tried 4K files at both 24p and 30p. All with the same result.


Thanks in advance for any help.


Current state of my project properties, but I have tried various options:

I have also tried changing my scaling from 150% (my usual) back to 100% as I remember having external display issues in VP 14.


EDIT: I have also just tried installing a 2nd Radeon VII from my other PC (that I have not dared to try yet) to see if a 2nd card would help with the external displays. No luck, still crashing.

Can you try unplugging one monitor and see if Vegas can figure out which is the external one?

You did set which monitor is for external preview under preferences/preview device?

hambonio wrote on 8/3/2020, 10:14 PM

I have tried that. Whatever monitor I have it set to goes completely black when I try to view it externally, then if I am playing in the timeline it slows to about 1 frame every 5 seconds for a bit then completely crashes or "whites out" then crashes.

If others don't chime in with ideas I'd suggest filing a tech support ticket with Magix detailing your exact set up and what you've tried to remedy it.

(I have 2 monitors and haven't had issues. I'm on NVIDIA, though.)

This is very interesting, because your system is nearly identical to mine (though your CPU is newer, I have a Ryzen 7 1800x), and I don't have this issue.

I do know some Radeon VII cards are unstable due to overheating (apparently it's difficult to get the heat sync to lay flat against the HBM2 RAM, from what I gather), but I highly doubt this is the cause of your issue. Mine has been solid, even in 32 bit HDR projects being sent to my LG OLED TV.

Just out of curiosity, do you have the monitor connected to the display ports, or the HDMI out? I'm using HDMI for the secondary.

One more thing to check... are you using the latest enterprise driver from AMD? They have separate drivers now for media production, that are supposed to be more stable than the game drivers that they give you by default.

I have exactly the same thing thing with a laptop w a rtx2070 maxq gpu. goes black / crashed the second i switch to full screen preview

fr0sty - I saw both options on AMDs site, I thought it was odd, I have never seen that before. I did try it. I wasn't even sure they were the correct drivers at first because it seemed to only have an option to install the entire Adrenalin software set they had. It should not be heat - even cold card on cold start up will do this immediately. I have never had a problem with at least VP 17, and VP14 I either had to have the main window on a certain monitor, or set my display scaling to 100% instead of 150% which made everything nearly impossible to read. If I did not do that I was only seeing half the preview on the other monitors I chose (I think I had a post about that last year, but shortly after VP17 came out and it was a non issue). Either way, I was at least getting some kind of display on the other monitors and it never did crash.

I am using 3 display ports on the back, no HDMI. All monitors are identical, and PC is in the other room (LARGE utility/storage room) so all wiring run to there for sound control.

UPDATE: I still do not have this fully figured out - but seem to have made a bit of progress, though I do not even know why or how.

I used Acronis to go back to the fresh windows install I had yesterday (I have used this software and similar software for more than 20 years without issue).

Oddly enough this time my secondary displays were working. The ONLY thing I did between this install over yesterday was physically add a 2nd Radeon VII, and then remove it - and both were on my "Full/Old" installation, so I never did it on the fresh Windows install. It only ever had 1 GPU installed.

While I was not thrilled about the new possibility of reinstalling every part of my system piece by piece - at least I was on the right track.


I ran into new issues though, and hope to get them answered here if possible without starting a new post.

So, I started installing all the parts of the suite. Realizing in the middle of this how many licenses I had on the other installation that needed deactivation - the headaches began again. At least Vegas itself you can deactivate other installations from anywhere, I wish other vendors would take note... I have since gone between both installations using the imaging software about a half dozen times this morning. I really need to take note on what I have in an organized fashion I guess, I kept forgetting about some plugins.

I think I have everything I need - or at least use on a regular basis on the new windows installation - with the exception of Spectral Layers 6. When I go back to the old windows installation and use the elicenser for it I see no way I can remove or deactivate the license. Am I missing something?

I would love to just have one installation of Vegas Pro these days instead of up to 6 versions like I have had in the past just to use specific plugins/features.

I WAS pleasantly surprised that I was able to get my Mercalli Plug-ins from VP14 to install and activate within VP18 - as I was never able to do so in VP17 - so I kept VP14 on my system and it was pain whenever I wanted to use them for cmos fixing or stabilization pulling clips from VP17 just to do it. I was never happy with the stabilization included with VP17.

The other plugin (not included with any of the VP releases) I have that I cannot use is my old Pluraleyes 3.5 - and have not been able to install that in anything newer than VP13 so that remains on my system as well, but I gave up hope on that years ago. I just sync up my projects in VP13 then open them in newer versions.

I do have other issues with playback and scrubbing in VP18 vs VP17 but I will make a separate post for that.

Thanks for keeping system images. You have brought me much joy.

HA! I will say I have never used it so much EVER as I have this morning. Going back and forth and back and forth back and forth all morning. I am sure my main m.2 SSD Loves me with all the rewriting on it today. But hey - each installation I keep going to was just as solid (or apparently not) as the last time I visited it!

I usually restore back to my main setup every 1-3 months just to keep it fresh.
