massive problem

[86JR]

yesturday i took my rig to a mate where we rebuilt it etc, put vista 64 on, installed all drivers and the pc worked perfectly.

got pc home today and vista said files were missing so i reinstalled it, now running fine again except i cant install any drivers for the card.

if i run it as standard vga adaptor it runs fine in 1680x1050.

when i install nvidia drivers, it wont turn the display on when it boots, it gets through the bios screen etc fine but when it loads vista i just get "no input signal - standby" on the monitor.

so far ive tried 180.42 betas and 178.24 officials and i get the same problem with either, im currently typing this in safe mode at 800x600!!!

What i dont get is it worked perfectly for my mate but wont work at all for me!!!!! theres been no BSOD's yet or anything, just no signal from card so i assume its a driver issue.

should i install the drivers from safe mode or something ?

thanks!!!

got it working now, but i cant run 1680x1050 which is nattive for my 22" screen, im forced to run at 1280x768 so the text is blurry and gives me a headache!

it seems this is a problem for everyone with nvidia cards + vista + lg 22LS4R screens (ie 22 inch screens which dont have or need drivers)

so thats that, now im forced to either buy an ati card (which have same issues sometimes ) or go back to xp 32 and lose 800mb of ram

Stole this from another forum:

search for nv_modes in the registry and replace the lines with the following, this is good for widescreen resolutions too. you will also have choices of 60/75/85/100hz. I have done it with all my vista installs. i run a 24" 16:10 CRT at 1440x900@100hz

Code:

{*}S 640x480=1;800x600 848x480 960x600 1024x768 1152x864 1280x800 1280x960 1280x1024 1440x900 1600x1000 1600x1024 1600x1200 1680x1050=20; 800x600 848x480 960x600 1024x768 1152x864 1280x800 1280x960 1280x1024 1440x900 1600x1000 1600x1024 1600x1200 1680x1050 1920x1200 1920x1440=10;

after you have done this, reboot and you will beable to choose 1600x1200 and 60-100hz

might be worth a shot, just make sure you backup the registry first!

thankyou, that seems to have worked BUT it only lets me run at 30hz interlaced, my monitor is rated for 60hz and when i select 60hz i just get "no signal" untill the 15 second safety net kicks in.... any ideas how i could change the code to make it 59hz ?

thankyou!

 

[Fatpigeon]

again, stolen from elsewhere:

-30Hz is Microsofts strange way to present 59.94Hz / Interlaced. NVIDIA on GPU TV Encoder support 59.94Hz or 29Hz the way the Microsoft Vista User Interface wants to reports it by cutting the refresh rate by half if it's an interlaced entry. So 30Hz is 60Hz/interlaced and 29Hz is 59.94Hz/interlaced.

Best regards,
NVIDIA

Also, have you tried using powerstrip? http://downloads.guru3d.com/download.php?det=169

update : couldnt fit it and monitor started making static / boiling kettle noises, so i reformatted this time using a shell and it took 2 hours

installing all updates etc this time im yet to try the drivers but if i have same problem then im not sure what to do....... might have to rma the card and get a 4870!!!

 

[86JR]

still doesnt work.......so ive ordered a 1080i/p compatible monitor..... 24" Samsung thing from ocuk, apparently comes tommorow, cant wait

just hope the 260gtx has enough power at 1920x1200 ?????

1680 x 1050 isn't a stand res with the Nvida drivers ... who knows why

In the Nvidia control panel select the 'Manage Custom Resolutions'

Then try the two check boxes
-Force HD resolutions
-Show modes not exposed by the display

That's how I have to get 16 x 10 on my 24" otherwise it's just not there

It certainly is with every set of Nvidia drivers I have used recently. I run 1680*1050 from my GTX 260 to my Acer 21 inch panel with no problems at all (1680*1050 is it's native resolution).

Try using the dvi to vga adapter and connect the panel using vga connector (assuming it has one) to rule out an EDID error.

im doing that now and get 1680x1050 on nvidia drivers.

But it moves the screen an inch to the right, black bar n the left and missing image on the right.

I guess the main problem is that the LG 22LS4R is actually designed to be a TV and not a monitor, however you should be able to adjust the image position using the nvidia control panel under display options.
