Question Spotty App Lag With New Monitor ?

[Merkabazen]

Upgraded my monitor 6 weeks ago from a Viewsonic VX2757-MHD 27" LED LCD to an
LG UltraGear 32GP750-B QHD 32-Inch Gaming Monitor . I immediately noticed some things ran slower, opening Windows Excel, Google loading when opening Chrome, clicking on social media notifications and waiting 5-10 seconds for it to load... etc. But only about a third of the time. The rest of the time everything opened instantly like it did with my old monitor.

I've tried to fix the occasional lag by dropping the refresh rate to under 100Hz, deleting old monitor profiles in Windows, updating drivers for the monitor and GPU, using the DisplayPort cable I used with my old monitor, plugging it in to the same port on the GPU... etc.
Besides changing the drivers and monitor profile, my system setup is the same.
My question is what is causing the occosional lag since I started using the new monitor?

GPU: EVGA GeForce RTX 3060 12GB
OS: Windows 10 Home
Processor: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz, 3192 Mhz
MOBO: ASUS ROG MAXIMUS X HERO (WI-FI AC)
RAM: 32.0 GB - 4x Gskill RipJaws V F4-3200C14D-16GVK

Use Task Manager, Resource Monitor, and Process Explorer (Microsoft, free) to observe system performance.

The objective being to discover what the system is doing or may be trying to do when the lags occur.

Use all three tools but only one tool at a time.

Look for unexpected or unknown apps, etc. running in the background. May be being launched at start up or perhaps in Task Scheduler and being triggered by some game or other action.

Just take your time and observe carefully. Leave the tool winodw open so you can continually watch for changes that occur with respect to when the lagging occurs.

Ralson18, Thank you for your response. Found out the issue was GPU firmware update. I had updated all the drivers and profiles... totally didn't think about GPU firmware.
