Windows 7 Can't Get Part 1600 x 1200

[Dark Light]

I have a 8800GTS 320MB and a GDM-FW900, which has a maximum resolution of 2304 x 1440. I've tried both the Windows 7 (64 Bit) and the Vista (64 Bit) drivers, and I can't get past 1600 x 1200. When I unhide the modes that Windows thinks aren't supported, I can select any res (after adding 2304 x 1440) in Nvidia's Control Panel, however when I try to apply 2304 x 1440 it applies 1600 x 1200.

I am only running a Nvidia GeForce 7900 GS but with a Dell 2405FPW monitor through DVI and I can get 1920 x 1200 @ 60hz
without any problems though I don't play games on my system.

OK people,

Since I feel to be the one that has done the most "test configurations" for this problem, I want to share another one with you. In the begin of this thread, I wrote a long article about what I've all done to solve the resolution problem with Win7 build 7000. Shortly after that, I have had a chance to test it in another configuration. The story follows:

My old configuration, with which I couldn't get above 1600x1200 resolution in Win7 build 7000 x64 was like that: Toshiba Satellite A100-912, Intel T7400 2.16 CPU, 3GB DDR2 RAM, Intel PM945 Chipset, NVidia Geforce Go 7600. And this configuration was not able to set the native resolution of my secondary monitor (1680x1050) with Win7 build 7000 x64 but the resolution could be set within the builds 6936 and 6801 (both x64).

The new configuration was like that: Samsung NP-R560, Intel T9400 2.53 CPU, 4GB DDR3 RAM, Intel PM45 Chipset, Nvidia Geforce 9600M GT. First I was afraid to install build 7000 directly as clean install, so I installed 6936 x64 and get the resolution working as I did in the old configuration. Afterwards and after making a whole backup of the working system, I upgraded to build 7000 x64. And guess what, the resolution was set without doing anything. The native resolution 1680x1050 was there in front of me.

Conclusion:

1. The problem may be related to the NVIDIA drivers. With Geforce Go 7600, I've used various drivers from laptopvideo2go website to get the resolution, but all failed even doing the test at the custom resolution management area in Nvidia control panel. BUT I haven't tested it with the drivers released from Nvidia for notebooks (179.28) since my old graphic adapter was not supported in the original inf and I tested the system before the offical release of these drivers. So, please be free to modify the inf of the nvidia's official driver for notebooks (179.28) and try to set the resolution and get back here with the results.

2. The problem may be related to the chipset. Since my old configuration was a PM945 chipset, which is pretty old, the resolution problem may be related to the chipset drivers or the chipset itself (the 945 chipset couldn't even address 4Gb RAM together). The new PM45 chipset may be the solution for this problem.

3. The system configuration or the codecs may be the real problem. Not every hardware works with every other one in totally peaceful and successful ways. Or even the codec related installations or the codec packages itself can be the cause of such problems.

What's next?

Waiting for your comments and possible configurations and test results. Please share them all..

What happens if you install a clean install of 7000 on your 2nd system, also what is the res of you laptop displays?

A clean install to the second configuration also works with all resolutions. All configurations have a native resolution of 1280x800 in their primary monitors..

What res can you get without installing any Geforce drivers, hopfuly you'll be limited to 1600 x 1200, which will mean that it's not 7000 it's self.

Anyone using 185.20 is using a hacked driver. If you get any problems with it, I would suggest using 179.23, or the latest Vista driver. 185.20 is basically a turd in a tuxedo.

Same issues - Can't get past 1600x1200 on 2nd Monitor

I finally made the choice to go to Win7 after my XP install crapped out on me. I've been fighting to get 1680x1050 on my second screen, with no luck whatsoever.... Anyone have any luck with this? I noticed the thread was a bit stale...

Specs:
Dell Inspiron 1505
GeForce 7300GO
Samsung 205BW LCD
Windows 7 Build 7000

Thanks!

not just Nvidia...

this problem isnt just confined to the nvidia cards you all seem to be using, i have an ATI 3870 sitting on a p5q D with an e8400 and 4 gigs of 1066 reaper and i have the same problem, either a max cap of 1600x1200 or it will go to 1800x1440 (the maximum my 21" 1997! dell trinitron will do) with a bit of twiddling but if a game is run or the system restarted you can kiss that goo bye and get bumped back to 1600x1200.
so yes the army of green is not alone in this problem and i really want a solution as i run most of my games at 1800x1440.

Since I wrote this thread I have got a new HD4870 1GB, due to my 2304 x 1440 res and CCC I couldn't get my res to work in XP. In XP I was limited to 1600 x 1200, after 4 hours I got my 2304 x 1440 res to work. I then turned to Windows 7 and I was able to get 1920 x 1200, 2304 x 1440 @ 60hz and 2304 x 1440 @ 80hz(with incorrect timings).

This is what I did.
XP
Installed the official Windows XP GDM-FW900 drivers.
Change the max res in CCC to something stupid like 3200 x 2400 @ 200Hz, since the GDM-FW900 doesn't seem to ab able to tell the OC and CCC its max res and refresh rate.
Did a reedit edit(not sure if this did anything).
Used PowerStrip to add a custom res, with custom timings.
At this point I got the res added @ 80Hz, however the timings were incorrect (the image on the screen was all wavy).
I then change, in PowerStrip, the timings (or refresh option) to give it back to the OS.
Worked fine, however the OS reports a Refresh of 60Hz eventhough its at 80Hz.

Windows 7
I tried to do the same in Windows 7 however the official GDM-FW900 didn't work.
Can't 100% remember what I did next, but I think I created custom GDM-FW900 drivers in XP with RivaTuner, then used it in Windows 7, I might have created custom drivers in RivaTuner again in Windows 7.
I then did what I did in XP, however in rededit the information there was all wrong, so I left it.
Then I did what I did in XP by adding a custom res in PowerStrip.
Then only problem is that I can't get 2304 x 1440 @ 80Hz with good timings.
The res is added, but then when I give the timings (or refresh) control over to the OS I only get 60Hz.
