Why doesnt W500 drive WUXGA external monitors at 1920 x 1200?

2009-07-14, 19:22 PM

I just bought a Samsung Syncmaster 245BW, a fantastic 24" 1920 x 1200 monitor. I also bought this Startech DisplayPort to DVI adapter, http://www.amazon.com/Displayport-To-Dvi-Cable-Adapter/dp/B0017K6BD2/ref=sr_1_1?ie=UTF8&s=electronics&qid=1247598897&sr=8-1

 

I plug everything to my W500 running Win7 (with the latest Win7 64-bit driver from ATI). Though I havent installed the drivers that came with the monitor.

 

The max resolution Windows lets me choose is 1680x1050. I want to to be able to drive this monitor at it's native resolution. What am I missing? Do I have to install the driver that comes with the monitor also?

Hi ice,

 

I Googled your monitor and found several people reporting being stuck at 1680x1050. Unfortunately there didn't seem to be consistent answer on how to get 1920x1200 native resolution on DVI. There were some suggestions on using ATI CCC, and settingt the refresh rate (which should be 60 Hz) before the resolution, not after. And some said to use VGA rather than DVI connection (which you could try, but that's hardly optimal). Anyway, here are the links, on the chance that something here helps you:

If you have access to a computer running a 32-bit OS, you might test your monitor with that. I think I saw a hint that the problem might be related to the 64-bit ATI driver.

 

There were other hints that the problem might be a bad EDID in your monitor, in which case you need to talk to Samsung...

 

Good luck, and please let us know how it goes,

I have had no problems driving displays with much higher resolution out of the displayport on my W500.  The first thing to check is under "Screen Resolution" (right click on the desktop) go to "Advanced Settings" and under the "Monitor" tab, make sure the button is unchecked where it says "Hide modes that this monitor cannot display." 

 

I have also had very good luck running the ATI Catalyst Control Center on Windows 7 64 Bit.  It should be at this link http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70417.  Best of Luck!

Hi meretricio and welcome to the forum! :smileyhappy:

 

Would you mind posting the highest resolution you've driven using your W500's DisplayPort?

 

Thanks!

I actually just ran a short film festival at a local theater off of my W500 into a digital cinema projector.  The projector was auto detected at 4096×2160, and I was able to output that resolution.  I could only run it as a single display that high (without significant artifacting), so I could not run the notebook LCD as a dual monitor setup.

@ ice

 

Are you cloning or extending your desktop? If you're cloning it will only present you with 1680x1050 (WSXGA+) which is the resolution of your internal screen.

That was extending the desktop, so I was able to run two different resolutions.  As I said though, this produced artifacting (green bands running through black areas, as on letterboxed films) so I ended up putting all of the ATI cards power into driving the projector.  Using the windows key you can press P in windows 7 to bring up a quick diolog to tell the system to duplicate, extend, or use the projector only.

Wow! Thanks, I didn't know the W500 would do such a high resolution. Do you remember what the input port on the projector was? DisplayPort, or DVI...? And what cable you used?

 

Thanks again,

Frank

The input was DVI, without HDCP (not sure if that matters, but it made us scrap the original plan of running the show off of a DVD, the player kept spitting back that it didn't have HDCP, so it would not play).  I used a Displayport to HDMI adapter, then an HDMI to DVI cable.  The high numbers startled me at first, but the show looked pretty good, so I was pleased.

This is the adapter I'm using.  From SIIG.
