Help - dv2315nr and external monitor

OK, so I just got an HP Pavilion dv2315nr a few days ago and hooked it up to a new Gateway 22" flat panel monitor. The display stinks, I am getting tons of flicker. The notebook screen displays fine.

1. I have two of the flat panel monitors and have tried connecting the notebook to both, still flickers
2. I have connected both of the flat panel monitors to another PC and they display fine.
3. Due to 1 and 2, I am convinced the issue is the HP notebook, not the external monitor.
4. I am trying to use 1680x1050 resolution (75 hertz), but would be happy with just about anything that doesn't flicker like crazy right now.
5. I have tried a bunch of the resolution settings and none of them get rid of the flicker.
6. I have updated the NVIDIA GeForce Go 6150 driver has been updated to 7.15.10.9815 (2/27/2007)

Has anyone else seen this issue and have any idea on how to fix it?
Thanks,
Dan

 

Use 60Hz with LCD monitors.

 

60 Hertz is no better.

you,re connecting to the monitor with dvi or d-sub?

i've had a similar problem... and solved it by buying a better cable... the new one has some new foam injection insulation... no flicker anymore.

 

Yeah, I totally second that... I was using the cable that came with my 22" Samsung to connect to a notebook (lenovo y410)... then I tried a different cable and no more flicker... it's gone.

 

yeah get a better cable

 

I had a similar issue with my dv9500t. It was the power strip I was using. I had to rip off the ground plug (long thin thing at end of cable that plugs into the wall). Once I did that, the flickering stopped. I just used pliers to rip it off.

But then again this might have been a different issue. See whenever I ran on battery power, the flickering would stop on the external monitor. thats how i knew it had something to do with power.

 

I am having the exact same problem. different model HP laptop (dv2416us) different model monitor (acerx223w) (widescreen 22") (running 1680x1050)

same nvidia geforce 6150 video adapter.

the driver I have is from 2/2007. the connection is dsub, (no dvi on this laptop)

flicker, wavering lines. very annoying

I am going to try updating to whatever new driver HP has on their site. I am not clear on driver updates on laptops and whether I need to use what HP sends out, or whether I can get a driver from nvidia. I went to the nvida website, and they seemed to indicate that their drivers for laptops are modified by manufacturere

 

Get one of those 3 prong to 2 prong adaptors and place it between your power strip and the wall outlet. You like me most likely have wiring problems in your house. (Ground fault loop)?

I used the adaptor and my flickering on my 22" Acer LCD is gone

boffo, I have the same exact monitor....

P.S. I actually placed the adaptor between my monitor and the power strip so that my laptop would still be grounded...

 

Well, I know this thread is a little old .. HOWEVER, I had to say thanks because your solution of breaking off the ground prong fixed my flickering problem on my DV9220us!!

I tried changing to a different power supply (iGO) and it still flickered. I am on an APC battery backup so the power is clean and there is no wiring fault (UPS checks). Broke the ground prong off (even though a different power supply didn't work, I thought it was pointless) and all is well in dual monitor land.

Thanks!
