Installation of docking station using VGA cable to monitor appears to degrade video signal. Will adapting docking station's DisplayPort to HDMI improve it?

Hello,

A coworker recently obtained a new docking station for her laptop and complained that her external monitor seemed "fuzzier" than it was.  Originally, we had her laptop connected via HDMI.  However, our IT support company connected the docking station with a VGA cable.

I theorized that the switch from HDMI to VGA was probably the cause of the video degradation.

When switching between the VGA of her docking station and "hardwiring" an HDMI directly from her laptop, she felt that the display did look better.  The difference seems barely perceptible, but I can imagine that staring at the screen for hours on end would make a difference.

When I looked at her new docking station, I noticed that there is no "HDMI out" port.  Rather there is a VGA, two DVI, and two DisplayPort (DP) out ports.  Her current monitor is only capable of connecting via VGA or HDMI cables.

Given this configuration, would you agree that connecting a DP-HDMI adapter to the docking station, and then an HDMI cable from adapter to the monitor is the BEST solution in this case?  Other than purchasing a different docking station of course.

It looks like I can purchase a DP-HDMI adapter for about $25.  So that's the way I'm leaning unless any of you experts believe there is a better solution.

You can try it, but in my experience I can't tell the difference between VGA, DVI and DP on any monitors that I've used.

Thank you.  I bought the adapter and connected DP to HDMI.  The user noticed improvement immediately and is now working  happily!
