Windows 10: Bad resolution when i connect my laptop to a 1366x768 LG monitor why?

I have a LG 28TQ515S with native resolution 1366x768, and i have it connected to my Laptop Asus Vivobook on Windows 11 23H2. I have tried the connection via a Dock and also directly via HDMI but i get the same result: bad grainy resolution on the LG monitor. These are the screen settings of my Laptop integrated screenand these are the monitor'sI have also changed the mode of the monitor between his native resolution 1366x768 and the 1920x1080 but i get the same results.

Laptop to Monitor Resolution


your laptop can only output 1366x768 - when you use "clone displays" -option, your full HD monitor gets restricted with this resolution. you need to "extend these displays" and then via display configuration set the correct full HD resolution to your monitor and the 1366x768 to your laptop monitor

 

External Monitor screen resolution issue (looses driver)

Greetings.

I have two external monitors connected to my laptop.

LG Monitor is connected trough a USB-C dock station to laptop. This dock has HDMI to HDMI.
A third monitor (tv monitor) is connected trough HDMI port on laptop.

Everytime laptop came from a "suspend" mode. LG Monitor looses resolution.
Also, LG HDMI monitor dissapears from "manage devices" list.

The three monitors (laptop monitor, tv monitor, lg monitor) works well UNTIL "suspend mode" activates.

Sometimes LG monitor is ok after a "suspend" mode. Cant tell why is that. But mostly time (90%) looses resolution.

Please your help

 

Windows 10 - Force higher external screen resolution - LG HDTV shown as non PnP monitor

How can I force the higher external screen resolution on Windows 10 (64-bit).

Configuration:

• Dell Inspiron 6400 laptop with Intel 945GM chipset, with VGA (D-Sub 15-pin connector) video output and correct 945GM graphics drivers installed
  
• Adapter VGA->HDMI (tried 2 types)
  
• LG 24" HDTV (1366x768) detected as non PnP Monitor
  

The windows allow only to set 800x600 or 1024x768 screen resolution (laptop screen resolution is 1280x800 so it is still higher than allowed on the external display). From what I remember the laptop is able to display at least 1920x1200 on external TV/Monitor.
Unfortunately there is no option in Windows 10 settings to go above 1024x768. In previous Windows versions there was quite easy to add or force higher screen resolutions but on windows 10 (with latest updates as per Nov 2019) it seems not that easy. I have tried to add the resolution, reinstall graphics and monitor drivers with no success.

I know it is an old laptop but it is capable of display 1366x768 resolution easily.

Can anyone help with the solution how to set the screen resolution preferably to 1366x768, please?
