Strange red dot on screen which does not seem to be a faulty pixel.

[GoodFella]

As of today, i am annoyed by a red dot (or a small filled red circle of may 2-3px width) that suddenly appeared right in the center of my screen.

My Specs:
OS: Windows 7 Ultimate SP1 64 bit and Windows 10 64 bit on a different hdd
CPU: AMD Ryzen 7 3700X
Motherboard: MSI X470 Gaming Plus Max (MS-7B79)
RAM: 32GB
Graphics: NVIDIA GeForce GTX 1080 Ti

What i ve tried:

- make a Screenshot: does not display the red dot.
- reboot: does not display the red dot while at POST, neither in the BIOS
- change the OS: begins to display the red dot once the user is in the process of logging in (dont have user/pass so it skips that)
- change the monitor: didnt display the red dot. then changed back to the previous monitor: didnt display the red dot at first, then rebooted and the red dot returned.
- unplug and replug hdmi: red dot vanished but returned after reboot
- change the graphics settings: while in grayscale mode, the dot was still RED, diff. resolutions, scales, orientations and even changing the refresh rate of the monitor didnt change the red dot at all.

It is almost like that dot people drew on their monitors in the 90s to play shooters with more comfort. Just not playing a shooter.

I m quite lost on what could be causing this .... any suggestions on what i could do to fix the issue?
Thanks in advance.

(i hope this is the correct sub forum)

Check the monitor OSD settings, manual and attempt to reset to factory defaults.

Some monitors have a gamer mode that displays a crosshair on screen.

Ha beat me to it @Regeneration I was just going say look in the OSD settings for gamer mode my AOC 24G2 does exactly that unless you untick it

Also at OP would have been nice if you would have told us what monitor you have

OMG you guys are great!!! it was fucking exactly that!

Yea, i should ve included the monitor, it is a

LC-Power LC-M39-QHD-165-C​

which happens to have a single button thing for menu navigation only, which, in my case, lead to misintended activation of the gamer mode - nice to know. i also got various crosshairs etc.

Thanks alot

glad you managed to get it sorted and yeah it is a pain the ass when it's on wouldn't so bad if it recognised a game and turned on but no it's on all the damn time making it probably the most useless and annoying setting monitors can have

That was me, just checking out some new nerf guns

Saw the title and knew it'd be an OSD crosshair, everyone beat me to it
