M860TU / GTX260M resolution problem with external monitor

Hi there, thank you in advance for taking your time reading this.

I have a Clevo M860TU with a NVIDIA GeForce GTX 260M, running Windows 7 64bit.

I'm trying to work with an external monitor, a YAMAKASI CATLEAP 27" LED 2560x1440.

However, this monitor has no scaling capability and the maximum resolution of my video card is 2048x1536.

I've been told in another message board, that my card's video memory is not enough to reach 2560x1440.

In that sense, I thought of increasing the shared video memory. However, there is no such option in my BIOS.

I think my BIOS version is 1.02.16 and, after reading the BIOS thread for older models, I know that I can update it to 1.02.17.

Still, updating the BIOS is a somewhat troublesome process. So, I have two questions:
- is there any other way I can increase my shared video memory?
- and if there is not, will the BIOS update allow me to increase the shared video memory?

I would really appreciate some help here!

i dont know too much about it as i only hook up my m860tu to my sony 3D tv to watch films using hdmi

 

Thank you for your answer.

However, your reference is for the GTX 260, and mine is the GTX 260 M -- GeForce GTX 260M | Specifications | GeForce

 

You arent able to increase the video RAM. Thats typically only possible with a integrated graphics card, when you have a dedicated one like you do you can only have what the card has built into it.
However I dont think this is a video card RAM problem. Are you using DVI, HDMI, VGA to connect to your screen? What issues are you running into? Do you get any picture at all, can you try that same port on another monitor to see if it works.

 

oopps! me bad. i didnt notice that

 

Thank for your answer.

I'm using a Dual DVI cable to connect with the monitor. The monitor was already tested and worked just fine with another computer, but with the same cable.

With my laptop, the monitor is detected, but it is not working -- I get a black screen and a blinking blue led (that turns red occasionally).

However, when I was messing with the custom resolutions on the NVIDIA Control Panel, the external monitor actually showed a frame (just one frame) of my desktop, and then it went back to the black screen. This happened twice, under some specific circumstances.

 

No problem at all. All attempts are welcome!
Once again, thanks for trying to help me.

 

ive never used a dvi cable so cant advise on that but its strange you got one frame show up.

you did try the Fn + F7 shortcut didnt you to switch to external display.

 

Yes, and all the other Windows actions I know that do the same thing.

 

If it is maxing at the analog resolution my doubt is that it isn't a dual link dvi PORT. I think the cable is fine however the port may not be. Might be worth looking into.

States "DVI" Needs to be Dual link for 2560x1440.

States it just a DVI-I port meaning it won't do 2560x1440
