I just bought an LG 24M38H monitor in order to connect it to my Dell Latitude e6510 laptop. I connected them through a VGA cable and the result was quite disappointed. The colors of the external monitor are washed up, and the text is very blurry. In fact, it is far more comfortable to read a text from the 15'' laptop screen than the 24'' brand new monitor.
I suspect that the problem occurs due to the poor quality of the VGA signal. Since the monitor provides a VGA and an HDMI input, and my laptop provides a VGA and a DisplayPort output, should the quality be improved if I hook up a DisplayPort to HDMI adapter to the laptop and connect it to the HDMI input of the monitor?
In that case, should I buy an expensive adapter, or a relatively cheap one should be just the same?
P.S. I use Linux Mint 17.3 with nvidia 340 drivers (the recommented), the resolution for both devices is 1920x1080, and I fiddled a lot with the on board monitor's settings before I ask this question.
P.S.2 I just checked that the DP++ logo is on the port. Does that mean that it is active? If so, does it make any difference?
Any thought would be appreciated.
