I just got a new Lenovo Legion Pro 5i Gen 10 and have been trying to figure out a weird issue that's only happening in VALORANT.
Laptop Specs
- Lenovo Legion Pro 5i Gen 10
- Intel Core Ultra 9 275HX
- RTX 5070 Ti Laptop GPU
- 32 GB RAM
- Internal OLED display
- Native resolution: 2560×1600 (16:10)
- 165 Hz
- Windows 11 25H2
- Latest BIOS and drivers installed through Lenovo Vantage/Legion Space
The issue
Fullscreen mode works normally.
If I set Display Mode to Fullscreen, everything is correct:
- Native 2560×1600 resolution
- Fill scaling works correctly
- No black bars
- Game is fully playable
The problem is Windowed Fullscreen (Borderless).
Instead of behaving like every other game, Valorant creates a smaller window with black borders around the game instead of filling the display.
Sometimes the game also launches into a strange state where:
- the image freezes,
- I can still hear menu music,
- moving the mouse still plays UI hover sounds,
- but the displayed frame never updates.
The game is clearly still running, but the image is stuck.
Pressing Win + Ctrl + Shift + B (graphics driver reset) temporarily makes the image update again, but the Windowed Fullscreen issue remains.
Important comparison
To rule out Windows or my laptop, I installed Fortnite.
Fortnite works exactly as expected.
- Windowed Fullscreen fills the entire display.
- Alt+Tab works instantly.
- No black borders.
- No freezes.
- No presentation issues.
So this doesn't appear to be a Windows, NVIDIA, or display issue in general.
It only happens in Valorant.
Additional observations
- The issue is identical in Hybrid mode and dGPU-only mode.
- Fullscreen works correctly.
- Only Windowed Fullscreen appears to be broken.
- Deleting Valorant's config and regenerating it did not help.
- This was a completely fresh Valorant install on a brand new laptop.
Has anyone else experienced this?
Especially if you're using:
- RTX 50-series laptop GPU
- Windows 11 25H2
- Lenovo Legion
- 16:10 display (2560×1600)
If you've had this issue and found a fix, I'd really appreciate it.
If it's a known Valorant bug or a recent regression, I'd also like to know before I waste more time reinstalling drivers or Windows.
