GeForce Go 7300 - don't get 1400x1050 resolution on ext. TFT (dual view)

I am using an Acer TFT-Monitor (AL 2017) with a native resolution of 1400x1050 as an external monitor for my notebook (Acer Aspire 5612-100 with a NVidia GeForce GO 7300 graphics card).

Using the windows display manager, respectively the NVidia settings tool I don't manage to set the display resolution to 1400x1050. I have tried different drivers: 83.40 (driver update from the acer website) and also the very latest driver (91.47 with modded INF. file).

For the 83.40 driver I found that 1400x1050 is in the modes list.

I'd like to work in dual view: 1280x800 on the laptop screen and 1400x1050 on the external TFT.

Actually I could set the resolution to 1400x1050 - but only for the notebook screen and not for the plug-and play 20'' monitor. For the plug-and play monitor (no matter if I use it as primary or secondary monitor) the list of possible resolutions (among them are 1280x1024, 1400x900 and 1440x1050) doesn't include 1400x1050.

I have also tried user-defined resolutions. 1440x1050 and 1600x1050 are allowed. 1300x1050 is rejected as an unvalid resolution.

Trying to add 1400x1050 I get a different message - 'the user defined resolution cannot be added'.

I am currently running the monitor with a resolution of 1440x1050, but this is still unsatisfactory as the the image is spoild by blurred stripes.

Does anybody know a better solution for this problem?

Thanks in advance,

Tom

Tom,

I've been having the exact same problem with my acer L 2017. My videocard supports resolutions higher than the monitors native but I still cannot manage to set 1400 x 1050 despite numerous attempts using many different drivers. In the mean time the monitor seems to enjoy 1280 x 1024 as a second best.

Nothing worse than buying a new 20" and not having it work at peak quality! If I come across something I'll post it here.

It looks like the Acer AL2017 is not behaving correctly.

Me too...

I have HP dv8286ea notebook with go 7400.

I can't set 1400x1050 for my new Viewsonic 2021m.

I'll let you know if I fix it.

Hi Jim,

I have an HP dv8327ea with a go 7600 and i also can't set to 1400x1050 for my Samsung 203B. Did you find out in the meantime how to solve this? I am thinking of installing the standard Nvidia drivers on my HP but i don't know if this will work.

Kind regards,

Erwin

I talked to HP, but the only suggestion they had was buying some sort of hardware box to convert the signal between the laptop and the monitor!

I think the only solution is to send your 1400x1050 monitor back, and get a 1280x1024 one(Which I know works because I'm using it now.). Has anybody got an external monitor working with go graphics which isn't 1080x1024?

LOL I doubt they could tell you something worse to do.

All you need to do:

- use the official driver from your OEM if it supports 1400x1050. (in order to limit the issues sources) Or 84.25 that support every single resolution ever found on this planet.

- plug the external monitor.

- boot the laptop.

- go to the display properties panel, then settings, then select the secundary monitor and set the proper resolution.

This has worked for me for years in all the possible combinations. Same resolution / Higher resolution / Lower resoltution. 1400x1050 is a pretty standard resolution... in fact it's even more standard that the ackward hybrid 1280x1024. (which should be 1280x960) Back in 2002 my Inspiron 8100 worked in that resolution.

Do you know where i can find this 84.25 HP driver for my DV8327ea (Geforce Go 7600)? It is not on their website anymore. I have the latest driver (84.54) but this one does not support 1400x1050.

Hi,

I have the same problem with a Quadro 700GoGL. I can get every possible resolution, but not 1400x1050 to display in dualview on the external monitor. This is annoying since our projector has 1400x1050 native resolution.

It works in clone mode and in horizontal spanning, but not in dualview. The resolution can be added neither through the nvidia panel, nor through powerstrip or rivatuner. It seems the inf here has the resolution in its mode string, but somehow the driver rejects it for the external display.

Any ideas?

Seems like more people are facing the problem with different hardware that always has nvidia graphics chip, e.g. http://forums.laptopvideo2go.com/index....showtopic=11986 .

The weird thing is that the resolution is included in the mode list of the modded INF files, but still it's not available in Win settings. So what is it that blocks it ?

Technically it should work, without the graphics card driver a switch to 1400x1050 can be done.

If your monitor came with a driver CD, be sure to install that one too.

It seems the driver is blocking it on analogue outputs. Using clone mode or dualview seems to trick the driver into still doing it. The monitor .inf doesn't have anything to do with it.

I was able to do a custom resolution of 1400x1048, and this displays on my projector, but I have no idea whether this was anywhere near 1:1 pixel mapping...

Same here: Acer TM 4652 with 15" display physicly supporting 1400x1050. Card is a Nvidia Geforce Go 6600. No matter what drivers, 1400x1050 is not supported on an external monitor with the same native resolution.

I was able to do a custom resolution of 1400x1048, and this displays on my projector, but I have no idea whether this was anywhere near 1:1 pixel mapping...

Thanks for this advice! I, too, could not add 1400x1050, but 1400x1049 could be added. The external monitor shows 1400x1050 (on the OSD). The clock and phase had to be adjusted, but up until now it looks like it's working.

Great! 1400x1049 on the external monitor is working with my GeForce Go7300 too. :) Got a blurred image first, but after auto-adjustment the image is ok. Thanks a lot!

Hello,

I have a Toshiba Satellite with Nvidia4 420 Go.

I am trying to connect a Samsung 205bw 20" widescreen monitor as a 2nd monitor with analog connector. I installed the monitor's driver, but still do not have the ability to set it to its native 1680 x 1050. I do have the option of 1600 x 1200 though. Im not sure if I am doing everything right. Did I read in a different post that it is possible to go into the nvidia driver and manually set the resolution? Will it help to update the Nvidia driver?

thanks

Rothie

1680x1050 is probably the same problem as 1400x1050. Just try 1680x1048 or 1680x1049 as a custom resolution. Updating drivers usually doesn't help.

I dont understand how to do a custom resolution. What tab is it under? I suppose it is possible that feature isnt available with my old driver...

Actually, you might just try installing a new driver from this site. I notice I do have 1680x1050 available on my VGA port, whereas 1400x1050 doesn't work.
