FIXED: Black screen on startup

Bugs
1

I’m on Windows 10, Lenovo y740 laptop with Geforce GTX 1660Ti. I’m not sure what my build number is but the installer executable is named TouchDesigner099.2019.19160.exe

I have been using TouchDesigner and everything worked fine, but then one day I started getting a black screen in the TouchDesigner window on launch.

Recently I have upgraded my Nvidia drivers to the latest version. I also removed all of the NVIDIA bloatware. I only have the essential driver and control panel right now.

I have also seen a thread on this forum with someone reporting the same issue. I’ve tried the solution proposed there (tweaking settings in NVIDIA control panel), but it didn’t help.
Reinstalling TouchDesigner didn’t help too.

Hello again. The problem was fixed by changing scaling from 125% to 100% in Windows display settings. This is super weird. Again, TouchDesigner was working normally with scaling set to 125% a week ago!
Huge thanks to TD Far East user group: Telegram: Contact @TDfareast

In the same build?! Or did you change builds?
Could you report which Nvidia drivers you were using there are also newer ones you could try now that might behave differently.

Same Problem here. Works with scaling on 100% but with 150% on 4K screen only black TD.

System: Win 10 - gtx1070TI - Nvidia Driver 457.30 - TouchDesigner latest

Thanks for the report @shufflerror, I saw this on another system this summer, but can’t reproduce anywhere. Can you confirm which ‘latest’ build, the official 2020.27390 or the experimental 2020.42700?

Thanks

Hi Ben, it is the .2020.27390 build. But after your reply i tried 42700 with the same behavior

I tried some random older builds down to 2017.30400 and none of them worked.
A version of TouchDesigner 88 (088.58140.64) started fine, but im not able to sign in, maybe its to old and not supported anymore.

Ok found a solution.
In the NVIDIA Settings i changend the Antialiasing modus to Application driven for TouchDesigner and after a restart of TD the Ui is there.

Thanks for the tip! We were finally able to reproduce the issue with this hint. The next 2020.40000 builds have a fix where we force this setting to be back to Application Controlled for TouchDesigner if we detect it’s been changed to something else.

For anyone finding this before that build is out (or using older builds). In the Nvidia Control Panel set ‘Antialiasing - Mode’ to ‘Applications-Controlled’. You can do this globally or just on the Program Settings tab for touchdesigner.exe if you want to keep it on globally.
