Ghosting, streaking and smearing issues can be caused by many things, least of which would be response time with any recent monitor. From the monitor side, it could be a crosstalk issue with the panel itself. It has to do with the rise/fall times with the monitor's internal signals. You can't do anything about this yourself as it's a design issue. You can use DisplayMate MM (multi-media) version ghosting and streaking patterns to see this if design is not optimized. It's a give and take scenario. The monitor/panel supplier may go for sharper focus clarity with VGA input and as a result they've got a minor ghosting issue.
Best things to look for when comparing monitors visually is this:
1) Black level - You will see a difference between panels here. Higher black levels = lower CR - contrast ratio.
Don't go by advertised spec. A monitor supplier will have at least two different panels qualified for each model and some monitor companies may have as many as 5 suppliers for one model if volumes are high. That's 5 suppliers at 2 panels per supplier. It's darn near impossible to get all of them to look the same.
And if you're buying retail (Best Buy, etc.) then it's a crap shoot because these "Consumer" monitors are not aligned as tightly as "Commercial" grade versions. Reason is that commercial companies routinely line up competitor monitors side-by-side and also line up same "Like" monitors to compare production consistency, uniformity, etc, etc.
2) Look at Red full field (full screen) pattern to compare color gamut issues. Good panels (Samsung, CPT) will have a deeper red than el cheapo crap panels like SVA and HST - Hannstar.
3) Look at full field light/dark gray pattern to check for Mura and light leakage issues. Light Leakage will appear around edges of panel, pretty self explanatory. There are many types of Mura issues these days. These may appear as dark or light spots around corners or vertical bands in the display.
4) Play with OSD color controls. Default color settings will typically be 6500K for any new monitor that is Vista certified because it's a MS requirement. Not all panels have native color temp of 6500K so that's not their best 'Look'. Most suppliers will have the panel native color temp set to OSD 'Custom Color' or 'User Color' depending on monitor mfr.
Ok, I'm rambling now...
Back to ghosting issue.
DVI is the way to go, but you can still have ghosting issues...but much less.
If you're using a VGA cable longer than 6ft. you can run into reflections, etc. that will appear as ghosting.
If using VGA, make sure your Clock and Phase settings are optimized. This is VERY critical because if not set correctly you will see focus clarity issues, ghosting, smearing, jitter issues. Be sure to use a 1on/1off type pattern when performing the AUTO adjust function (sets clock and phase). It won't optimize correctly on normal Windows desktop. Most monitor companies should have a utility for this function (HP, CPQ, Dell, Samsung).
From the system side, Up solution cards (plug-in) will have cleaner VGA signals than down solution (motherboard). Notebooks are the absolute worst. Mainly due to added filtering to output so that mfr can pass EMI testing. The filtering rounds off the square waves to almost sine waves. Hard for monitor to detect start and stop times of sync signals so makes it harder for them to Auto adjust. You may also see softer focus if signals are really degraded. Same thing is seen when running very high resolutions on those limited memory video cards. Bandwidth issue.
That's another 10 pages of text so will leave that one alone.
oh, one more thing.
For 99% of LCD monitors, 60Hz modes will look better than 75+Hz modes. Slower refresh rates of video cards = cleaner output signals = cleaner video. Monitor internal circuitry converts anything higher than 60Hz down to 60Hz anyway. That's the panel native rate.
cheers.
... i mean if i hit a ball hard it sometimes showed 1-2 cm of trail behind it .. omg. Other than that i didnt see much ghosting in anything else i played/watched.
