Windows 7 on Latitude E6400

there is no way that this is OS dependent either. which version of the nvidia driver are you using?

 

I have tried 2 or 3 NVS 160M driver versions, currently using 8.16.11.8840 released on 14. 12. 2009.

 

Can you please be specific, which drivers have you tried? Did you uninstall the old one and restarted your computer first? or did you just install over.

AHH Here is an idea... I think I know what is the problem, I had this problem with a 22inch Samsung via VGA cable. Create a custom resolution, but don't make it 60Hz, but rather 59.997Hz, if that doesn't work try 59Hz. The problem is that Windows 7 doesn't round the Hertz.. well it does, but for some reason the 60Hz range is rounded down. You have 2 types of display 59.997Hz and 60.001Hz, this simply depends on the lamp technology used and transformer (if it's a CFL lamp). My Dell U2410 is a 59.997Hz.. so in previous version of Windows, you see 60Hz, while in Windows 7 you have 59Hz (which is 59.997Hz and can confirm this by looking at the monitor on screen options, whee it says the resolution and receiving a 60Hz signal (59.997Hz rounded up))

 

Thanks for hint. I have tried completely uninstall old Nvidia drivers first (keeping standard VGA driver only) and then install latest

- Dell E6400 NVS 160M driver (14. 12. 2009 version 8.16.11.8840)

then uninstall again and then newer (based on version id, not date )

- NVIDIA NVS160M compatible with E6400 (20. 11. 2009 version 8.17.11.9562)

Both drivers are similar , but NVIDIA's one is more aggresive when trying custom resolutions - it warns that it can destroy my EIZO - and really.. I have made 10 attempts and picture was shaking and monitor bit noisy, even at ranges between 59-61 Hz. so no luck with custom resolution with both drivers.

Btw, one of prictures is offering an option to set 1680x1050, but this was with unknwon Windows online driver, installed by default from Microsoft site - when choosing that native recommended res - blank screen for 10 minutes was the result - so hard restart was only option

Anyway, if you look at pictures attached, especially at "nvidia_hd_supported_res.png", it seems NVIDIA drivers do not bother with 1680x1050 res actually, I suspect because DELL laptops are not equipped with this panel res.. whereas 1920x1080 panel is assembled with E6500 for example. This is not true for VGA cable, of course. This is quite strange but seems to me like explanation what is happening.

To summarize, I am really surprised that even HW/SW is more and more fantastic in these days, sometimes wrong things happen

 

Hmm, perhaps you should ask under Nvidia forum, onto why you have these side affects when forcing a resolution, perhaps there is some settings that needs to be set. For me it sounds like the horizontal and/or vertical polarization are wrong for your monitor, but take what I am saying at a grain of salt - don't break your screen by trying. I know that EIZO is a Japanese company, so perhaps it follows different standards then in North America (just guessing).

I don't think so. My monitor is 1920x1200 (1200p), and I don't have this problem with my display port (my monitor takes DisplayPort).

 

Actually I agree with you .. I just said that I cannot see on "nvidia_hd_supported_res.png" resolution 1680x1050 listed, but yours (1920x1080) is there - so should work.

Thanks for link to Nvidia forum ( I do not like ad-hoc frequency/pixel clock/phase changes with potentional harm to my Eizo anymore ).

My resolution is NOT 1920x1080.. but 1920x1200. Which is my point that my resolution is not part of the "HD" presets that you see. You and I have the same aspect ratio (16:10) and my resolution is higher then yours. So normally, the GPU should handle your resolution properly.

Would it be possible to try a different computer with the your EIZO awesome display via display port? What i wonder, is that maybe your EIZO has a manufacture problem by pure bad luck. OR Perhaps you can communicate with them and see how to setup your screen properly, maybe they know the exact information to put it to ensure that everything is proper. I mean, we are talking about EIZO here, and not some crappy brands.

 

EIZO support has confirmed that S2233 was tested with two laptops ( mac and acer ?) and worked at 1650x1080 when connected with DP cable.

As I wrote before, the problem I see is that NVidia driver does not list 1650x1080, just res below and above (i.e. 1920x1200). I started discusion on Nvidia forum, maybe one day it will work.. at least VGA connection works reasonably well.
Anyway, many thanks for support on this forum.

Hi,

I recently installed Win7. Since then it looks like the cd/dvd burner I have fail to do the job. Just prior to upgrading to win7 I had to burn some iso and it worked fine but now the errors I get is somehting like the disc is not compatible or something like that.

I googled a few times and I found this post: Latitude E6400 can't burn cd's - Disk Drives (HDD, CD/DVD, Blu-ray) Forum - Disk Drives - Dell Community
but gave me no joy so far. I also tried to install the latest drivers from dell's website but still haven't manage to get something working.
My drive ref number is PLDS DVD+/-RW DU-8A2S.

Thanks in advance for your help!
