Attached your see my live preview from my 4K monitor. Works perfectly fine in my 1080p monitor. When I downgraded back to version 27. Live preview works fine in both monitors. Something wrong or needs to be patch with the latest version? Or is there a setting I need to change somewhere... any help will be greatly appreciated.

Is your display scaled in Windows? Maybe try disabling that scaling temporarily to see if that fixes it?

Another idea is to remove any plugins you're using temporarily to see if that fixes it. Basically, keep trying until you see something.

Also, are you on v28.0.1?

Are you referring to the "fix scaling for apps" if so.. ive already disabled it.
The plugins i currently have are (according to my logs): (I believe these are on default with OBS. And yes I'm on latest 28.0.1.

Few things you can try:

See what that setting's set to.

Try setting the scale in Windows to 100% (if you're on Win10, it looks completely different):

I checked your DLLs against mine. They look right. I have a 32-bit and 64-bit folder.

Last idea is rename your OBS configuration directory:
```
%appdata%\obs-studio
```

Rename that directory to `obs-studio.bak` and re-open OBS. See if it works on a new set of configs.

If not, delete the new configs and remove the `.bak`.

Ok I changed the scaling to 100%... but now the font and everything around is WAY too small for me to see anything lol. My recommended scaling is 175%.

Something I also noticed... after i switch to 100% scaling.. now the recommended resolution is 2560 by 1440. (I'm assuming that 2K resolution is the best I can do). At least I can see everything now and better yet... OBS preview live looks fixed too.

This is great to know!

But what fixed it? Swapping the scaling down and back up? Deleting your old configuration data?

If it's scaling related, and you have to be at 100% now, the real issue would be an OBS bug related to high-DPI mode if there's no an even scaling. Last thing we can do is fix the DPI mode in Windows only for OBS.

If you right-click the OBS shortcut, you can go to the Compatibility tab. After that, look for the DPI scaling setting; then you can make Windows higher DPI, but only this app runs at a lower DPI. I've done this to games in the past which don't support more than 100% scaling.

Brilliant! working like a charm now! Fix was the Swapping the Scaling down and back up. Didn't need to delete any configs.
I even went ahead and did the DPI mode. Didn't even know that was a thing. But it's working now!

Thank you so much for your help!
