    Am I right to insist on digital out (HDMI more convenient; DisplayPort -adapter would be needed for HDMI-only in 1080p HDTV but technically DP could support higher res monitors if needed) for new notebooks-netbooks or can VGA quality really compare?

    {For end users demanding best display quality experience}...

    Thanks for your thoughts,

    HDMI > VGA hands down. I went from grainy image with completely off coloring to sharp accurate coloring. DVI should be same as HDMI for most people.

    If you have a short and good VGA cable, the image quality will be the same as DVI and HDMI at 1080P

    I've never noticed any obvious difference on my desktop monitor, a 22" ViewSonic LCD with both VGA and DVI inputs. The main difference is that VGA only supports up to 1920x1200 resolution, and DVI and HDMI can do up to 2560x1600.

    VGA technically has no resolution limit. You're limited only by the graphic card's DAC, your monitor's ACD, the cable's bandwidth, EM interferrence..etc. A good vga cable can go way beyond 2560x1600.

    I think it's just that many older cards only support up to 2048x1536 through VGA.

    So digital out (HDMI, DP) is an overblown issue over standard VGA out in terms of quality?

    I still hear theses conflicting reports...Thanks

    I'm also one of those who can't tell a difference between VGA and DVI/HDMI, but they say digital output is the best so umm.

    With my 24" monitor, I would get interference with my VGA cable, but now with the HDMI/DVI cable, there is no interference. This is at my office at a manufacturing facility. Interference meaning 1 or 2 faint lines coming down the screen.

    That could just be a poorly shielded cable.

    I got interference with VGA on my LCDs, and when I switched to DVI, it was gone. Perhaps it was bad grounding or bad cables.

    Ideally I'd like both VGA & HDMI or DP for direct compare & HDMI-DP carries audio in 1 cable but VGA only out should not really be a dealbreaker in terms of display quality itself ?

    I'm not clear on all the fuss then if it's not really a significant improvement, just marketing hype?

    If you have proper cable (not those ones where you buy from flee market for $1), you won't notice the difference between VGA and HDMI/DVI at 1080P resolution.

    I keep reading conflicting reports such as above & proper cables no difference at 1080p so still not sure..

    http://en.wikipedia.org/wiki/Hdmi

    I know I prefer the HDMI input over composite on my HDTV & DVI over VGA on monitor or can good VGA cables really fix it?

    With good cables, you can't tell between DVI/HDMI, VGA or Component at 1080P.

    It's basically Digital Vs Analog Signals. They're all capable of achieving beyond 1920x1080 resolution. Analog singals is prone to EM interferrence, but if you have a properly shielded VGA cable, EM inteferrence won't be a problem. Digital signal is prone to data corruption. If you have a working cable, you'll have no problem outputing 1080P signals from a digital source.
    If everything is working correctly, a normal person shouldn't notice any difference between analog signal vs digital signal.
