I have an old LCD monitor (Dell Inc. 22'') that I am now trying to use as a second monitor to my laptop (Lenovo E460), running on Ubuntu. I would like to see if I can make this monitor less hazy/blurry, with a software that can tweak some adjustments. (It is now absolutely useless if I want to read text on it.)
The text is blurry and it hurts the eyes after only a few seconds.
On the high-contrast regions of an image, a shadow of the darker region would be cast over the brighter region. This could be the reason for the text being blurry.
This is connected to my laptop via VGA -> (New) Converter -> HDMI.
My Lenovo is running on Ubuntu, with a built-in display with resolution of 1920X1080.
All window content is set to match with the higher resolution screen (1920X1080 of the built-in monitor).
Using the monitor settings to modify the sharpness/brightness/... of the display did not improve a bit.
A Clue: When it is not connected to any source, the error message on the screen ("No input signal detected") seems sufficiently sharp!
