New M6500 Discussion Thread

I believe "pulsing" the LEDs is normal, due to the fact that LEDs really only have 2 settings; on and off (not entirely true, but at a general level, mostly true). Thus, to achieve anything less than full brightness, they're pulsed at very high frequencies. Maybe try cranking the brightness all the way up and see if that effect disappears. If so, then you have your answer.

 

Well, I guess that's the reason. Cranking the brightness all the way up makes the effect considerably less noticeable, but I still can see it. They could have bothered to sync the pulsing in order to at least get rid of the colorful red green blue trail. It would be much less irritating then. Maybe the Samsung is synced or has a higher pulse rate???

Hmmm, I seem to not only have color sensitive wide gamut eyes, but extremely fast sampling ones too. They should be used in LCD panel development.

 

Well, if they were synced (assuming they can be, due to possible different inherent brightness levels), then instead of your occasional red green blue trails, you'd have periods of completely blank screen instead. I'm not sure which would be better.

 

Looking forward to getting rid of the 3800M, it really is a crash magnet.

 

Touchpad scrolling in FireFox (3.x and 4) on Win7 x64 hangs the mouse completely. Either with two finger scrolling or by using the right border. SynTPEnh.exe goes up to 13% which is one complete core on my 820qm.

The mouse stops moving until I kill syntpenh.exe.

When I kill syntphelper.exe as well and restart syntphenh the gestures start working again. Try in FF again and the mouse fails again. Seems a 100% repro here.

Scrolling in IE8 and Chrome or any other app has no issues.

Does anybody else see this as well?

I am using the current Dell synaptics drivers - 15.1.6.2

 

Yep had that exact problem with my old unit (new one on its way not for this reason though)

Seemingly at random the trackpad stopped working, only way to ensure 100% reliability was to not have any synaptics drivers installed at all.

 

Just for FireFox, too?

Would be nice, when you report back how it goes with the new unit.

 

Quite possibly just in firefox. Sometimes it would work for a while and sometimes it would stop soon. I never really took the time to diagnose it as it worked just as well without the driver.

 

Good point. Anyway, LEDs shouldn't mind high frequencies like 200Hz or more. This would be a simple way to eliminate this irritation for people with "fast" eyes.

 

Hmmm, checked again after your post. Regular Dell driver, no issues in FF, never had any, but haven't used the touchpad intensely so far.
