Laptop freezes when external monitors go to sleep — started after using ATAS trading platform
Hi everyone,
I’m trying to figure out what could be causing my laptop to freeze completely.
My laptop is a GIGABYTE GAMING A16 CWH with the following specs:
- CPU: 13th Gen Intel Core i7-13620H
- RAM: 32 GB
- GPU: NVIDIA GeForce RTX 5070 Laptop GPU, 8 GB
- Integrated GPU: Intel UHD Graphics
- OS: Windows 11
My setup:
- One external monitor connected via HDMI
- One external monitor connected via USB-C
- Laptop internal display also active
The problem:
Whenever my monitors go into power-saving/sleep mode, the whole laptop freezes. I can’t wake it up properly and usually have to force a restart.
This only started happening since I began using ATAS trading platform.
In ATAS, I usually have:
- One chart open on one external monitor
- One chart open on the other external monitor
- Two heatmaps open on the laptop screen
I suspect it could be related to GPU rendering, multi-monitor handling, ATAS using OpenGL/DirectX, or maybe Windows power management switching displays/GPUs when the monitors sleep.
Has anyone experienced something similar with ATAS, multi-monitor setups, or NVIDIA/Intel hybrid graphics laptops?
Things I’m wondering about:
- Could this be caused by ATAS’ renderer settings?
- Should I use OpenGL, DirectX, or GDI in ATAS?
- Could Windows be switching between the Intel iGPU and NVIDIA GPU when the displays sleep?
- Are there specific NVIDIA Control Panel or Windows graphics settings I should change?
- Could USB-C display output be causing the freeze?
- Should I disable monitor sleep completely while ATAS is running?
Any ideas on how to troubleshoot this would be really appreciated.
Thanks!
