Re: HP w1907
Not always: vga signals on videocard are filtered by a low-pass filter in order to reduce emi and to obtain an FCC certification.
On cheap boards these filters (usually a series of capacitors and inductors near the vga connector) employs low-grade components, so the screen results is usually dizzy, the sharpness is low, colors can be altered and so on. Matrox cards, Ati-manufactured Atis and some Creative ones usually employ[ed] better components with stricter tolerances, so they were claimed for their beautiful images; Matroxes were [and often are] the reference for monitor tests.
Dvi signals should be unaffected by this filter, so their quality is (unfortunately) unimportant for today's card.
OTOH, the vga cable may be unshielded and without ferrite rings, so they catch almost any interference: this was common with 12 and 14", because they had a low resolution, but is almost unique nowadays, since even low-class monitors are shipped with a decent cable.

I guess they could have moved onto cheaper manufacturers like my Samsung monitor. It does not use a Samsung panel even thou the same model used to! 
I guess they shifted manufacturing of this model over there, hopefully they stuck with an LG.Philips panel. The manufacture date is December 2007, and the FCC ID starts with BEJ, so we know for sure it was made by LG. Too bad this isn't a very popular model, otherwise someone would have figured out how to tell what panel you have without having to crack it open by now.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
