My new Dell had the same problem, blank Activation & Help screens. Changed from the recommended 1920x1080 with 125% resolution to 1920x1080 with 100% resolution and this fixes it, however the text is very small. After activation changed back to 125% so I could read text. If you need to use help you have to change the resolution back to 100%. Aa real problem that TT needs to fix. Changing the resolution does not require a restart of TT.
