pixelated screen problem ever since I bought my new pc and monitor

So a few months ago I bought a new pc and a 1080p fhd monitor
the screens always been very pixelated though

I cant really tell if its a problem with the monitor or the pc, sometimes when I go on and off of fullscreen on youtube videos or games things go normal for a few seconds but it always ends up getting pixelated again not even a few seconds after

Ive tried most fixes, updated and reinstalled my driver, my pc resolution is the same as the monitors resolution which is 1080p but nothing really seems to help, at this point any new fix is helpful, Ive been thinking of replacing my monitor but Im also scared its just a problem with my pc or nvidia control panel settings

for my graphics I have an nvidia 3060ti and an 11th gen intel core i7-11700

 

Second monitor appears pixelated sometimes

Before we get started, here might be some setup information that may be worth noting. My primary monitor is a 1080p, 1920 x 1080 (native) using an HDMI to DVI. My secondary monitor is a SONY TV 1360 x 768 (native) using an HDMI. Both are connected to my graphics card and not the motherboard. I have always had this setup but I have not always had this issue.

Preforming the following actions may cause my second monitor to appear pixelated.

• Getting a web browser out of maximized mode by click dragging the window or using the restore button
• Using full screen on the secondary monitor
• Dragging a window into the second monitor, sometimes

In order to temporarily solve this issue I must apply a change to any display using the Nvidia Control Panel. Using the Windows display settings to apply a change does not always fix the issue. Also note that after the second monitor goes pixelated, my computer does not detect a change in any display's resolution settings.

So far I have tried the following fixes to no avail

• Keeping display drivers up to date
• Using a DDU to wipe display drivers clean and start anew
• Using the Hardware and Devices troubleshooter

I have tried to use capture software to screenshot the pixelation but it can not see it. I have to use a camera to show what it looks like instead.

Capture software is not capable of detecting the pixelation so I have recreated what it looks like on screen. Use this as reverence if the pictures look bad.
