Monitor - Refusing Native Resoltion

[CorruptedSanity]

I just bought a Samsung 2493HM monitor to replace my Samsung 226bw.

I cant get it to its native resoltuion of 1920 x 1200.
When I try to set it to that resoltion, it goes all the way down to 800x640.

At first, I disconnected the DVI & power cable from the 226bw and connected the new monitor to those same cables because the DVI is the same and the power cable also looked identical. No harm using the older power cable, especially sinced its encased in a cable-management thingy.

Any way, there was no screen, so I restarted the computer and saw the BIOS screen and the Windows XP loading screen, but nothing after that. I have my LCD TV hooked up to my graphics card too (2 DVI slots), so I guessed I needed to install the drivers. But popping in the Samsung Drivers CD gave me nothing. It would not show up. I thought the CD was busted so I popped it into my laptop, but it worked! So I downloaded the drivers from samsung.com and selected the 2493HM Digital drivers and installed, then playing around in Nvidia control panel, I got the monitor to work, but not on its native resoltion. The highest I can get it to is 1920 x 1080, coincidentally its a full HD monitor.

Any idea why their driver CD wont work and why I cant get it to its native resolution?

Thanks

It sounds like the computer is seeing this as monitor 2, and not the primary display device.

guns!

Very smart, it was at first, but I managed to get it to Primary but still the smae.

Is your DVI cable dual link? Make sure you are setting the refresh rate properly. Probably 60 Hz.

Hi guys!

Problem solved.

Turns out Nvidia had set this monitor as "Treat as HD TV" by default.

Untyicking this option allowed me to set it to its native resolution of 1920x1200.

Thanks a bunch and here are some tips for future readers (which did not help me) because my problem required me to untick the "treat as HDTV".

Plug everything back in the way it was.

Boot, device manager, uninstall all monitors and all video drivers.

Not everything!

Shut down.

Plug in the new monitor with the new cables. Let Windows find a monitor. Try the driver cd again.

Just another thing: never unplug or change a screen while your pc is up.
You need to shutdown unplug old and plug the new one. Windows will recognize it (and maybe your screen would not have been installed as a hdtv)

cd090580,

You are most correct!

Also, dual link DVI-D isn't needed until monitor resolution exceeds 1920x1080.

There are two 1920x1080 resolutions under VESA.

The single link version is called "HDTV" -- (1920 × 1080) @ 60 Hz with CVT-RB blanking (139 MHz)
All consumer HDTV equipment use single link DVI-D or HDMI.

The dual link version is called "Dual link HDTV" -- (1920 × 1080) @ 85 Hz with GTF blanking (2×126 MHz)
Dual link is mainly used for higher resolutions mainly for pro CAD, 2D graphics and 3D animation. This dual link standard won't work with consumer HDTV equipment but may be possible from a "pro" computer display card to a dual link capable computer monitor.

He said he's using a 1920x1200 monitor. But it looks like single link DVI supports 1920x1200 at 60 Hz.

Im not sure if its single or dual link DVI.

Single link is all you need.

My monitor has a DV-D Dual Link port
