hey guys I am not sure what the deal is. I bought a samsung t240HD and no matter what I do I can't get it to run at 1920x1200 even though both the monitor and GPU are rated for that. Drivers are updated as well. Any ideas?
March 26, 2009 10:00:31 PM

Did you install the driver for the monitor?

Stupid question, but I have to ask: using DVI port right?

March 26, 2009 10:38:59 PM

yes using DVI and yes installed driver for monitor, actually Vista picked it up on its own, didn't need the monitor driver. I can get it to do 180p settings but it makes everything run terribly slow and stretched out. The funny thing is that native should be 1920 x 1200 on this monitor. Thats why I thought I should post it here to see if anyone else had an idea.

You don't mention what video card you have.

Ahh... glazed over that somehow... Who makes it??
March 26, 2009 11:18:02 PM

Hey sorry, I just realized my first post was pretty sparse on iformation. My full specs are:

gigabyte ep35-ds3p
intel e8400
8GB OCZ ddr-1066
ASUS Radeon 4850 512MB
Corsair tx(HX?)850W
Vista 64 bit

Ati Drivers are all updated. I really don't get why it isn't just plug and play, anyone else have this monitor?

March 26, 2009 11:44:22 PM

I run the t260 and did not have any problems with the resolution once the vid drivers were installed. I am running win 7 so I just right click desktop and go to screen resolution. I don't set the res in the nvidia control panel.
March 26, 2009 11:46:24 PM

Yeah I downloaded that already, unfortunately it didn't make a difference. Do you need to use an HDMI cable to get the proper resolution?
March 26, 2009 11:59:02 PM

I could be wrong about the HDMI cable, but I don't think that should matter.

Question.... do you even get the option to set it at 1920 x 1200 ???

As chef said... Right click the desktop... Click Personalize... Click Display Settings....
Click Advanced Settings button... Under Adapter Tab, click List All Modes...

Is 1920x1200 on the list???
March 27, 2009 12:05:05 AM

nope, 1920 x 1080 is on there but x 1200 isn't, the only reason 1920x 1080 is even there is because i forced it in there with the catalyst software, originally it wasn't going past 1680 x 1050.

I have the T240HD, only diff is I have the 4870 w/512 Meg GPU. Also didn't try the DVI cable as I have a Blu-ray recorder and Blu-ray playback pretty much requires HDMI cable with I used from the Get go (With DVI->Hdmi adaptor)- Had no problems w/1920 by 1200

HDIM is not required for either blue ray or displaying 1920x1200. DVI and HDMI are the same thing minus sound on DVI. There is no bennifiet of running dvi over hdmi unlass you are running sound to your monitor.
March 27, 2009 12:28:46 AM

I have T240, i never heard of this before, what is the lowest and highest resoluton in display settings?
March 27, 2009 12:32:46 AM

What hertz are you at? Make sure it is set to either 59 or 60.
March 27, 2009 12:45:33 AM

Lowest and highest resolutions that I am picking up are 640 x 480 to 1680 x 1050. hertz is set at 60 but I have fooled with it at 59, it also list 23 and 24. It runs fine with it at 1920 x 1080 but it is stretched irritably. I would be fine with leaving it at that but the fact that it is rated to 1920 x 1200 makes me want to keep trying to find out why it isn;t working at that resolution.
March 27, 2009 12:48:11 AM

You said you forced 1920x1080? How did you do that?
March 27, 2009 12:57:16 AM

Okay man I know the exact answer to your problem. With your standard DVI cable you will only be able to do 1920 x 1080. You'll have to pick up a DVI-D that will do 1900 x 1200 - 2500 x 1600 and beyond. Your problem isn't the monitor or video card... just a simple cable. Just go out and try to find a DVI Dual Link cable and it'll work. If you can't find one in town then TigerDirect.com and Compusa.com have a bunch of them for only about 15-20 dollars. Don't worry about getting an expensive cable though just make sure it says DVI-D or DVI Dual Link.

Here is a link to a good one.

DVI-D is standard cable with most everything now. Stands for DVI digital. It comes with any monitor that has a dvi cable included such as the T240. This is not his problem is he is using the cable that came with the monitor.DVI-D single link which is what comes with monitors 27" and below support up to 1920x1200. A dual link DVI-D supports higher than 1920x1200.

these monitors come with the cables. I am starting to think uninstall ati drivers and reinstall. use driver cleaner pro. somehting aint right. or reset mointor, buttons on the right side.
March 27, 2009 1:04:31 AM

Give that a try and see if it works .
March 27, 2009 1:05:11 AM

Sorry, wrong words, it wasn't forced I meant to say you have to add the 1080 support to the display manager within the catalyst control center. Thanks for the input on the DVI-D cable mamw93, unless something else comes up I will try that, I just want to see if there are any other explainations for this anomaly. I don't mean to doubt you or anything I am just having a hard time believing that they would package a monitor that proudly displays 1920 x 1200 and then ships a cable with it that doesn't support that format. But hey it could happen!

The cable that shipped with the monitor is a dvi-d single link.Quite capable of supporting up to 1920x1200.

Hate to be a lazy bum but could you recommend a good program for wiping drivers and if possible a download link to it. Tks
March 29, 2009 1:44:31 AM

Hey there... I just found this information while looking up info for another post....

http://computer.howstuffworks.com/monitor3.htm

The info includes this tidbit...

DVI cables can be a single link cable that uses one TMDS transmitter or a dual link cable with two transmitters. A single link DVI cable and connection supports a 1920x1080 image, and a dual link cable/connection supports up to a 2048x1536 image.

If this info is correct... I believe you just need a DVI dual link cable.
March 29, 2009 2:10:41 AM

that is incorrect. a single link supports 1920x1200. Thats why when you purchase a monitor under 30" you receive a single link cable while 30" and above you receive a dual link. I am using single link with my t260 at 1920x1200.All you have to do is look at your cable. If there are missing pins in the middle it is a single link cable.

Well we have no heard from him since he reinstalled the drivers. I am pretty sure it is a software issue.
April 21, 2009 9:38:05 PM

Hey sorry I never checked back in on this after a little bit of inactivity. Nope reinstalling the drivers didn't work. I called Samsung about it and they came up with the same dual link cable idea so to satisfy them i got a dual link cable and no dice. I am probably going to call them back tomorrow and see if they wil replace the monitor or not as apperntly there are quite a few people having the same problem with the t240's. Tks for all your replies and i will try to update it once I get the thing fixed.
April 25, 2009 2:43:05 PM

I currently have the same issue.

Just bought a Dell 540 with ATI3450hd 256mb. Try Dual link, single link DVI and HDMI do not work. Get 9400GS card still doesn't work.

I have the same problem, it's not the monitor. I hooked up a windows XP pc and loaded the Samsung driver and the monitor works at 1920x1200. Using the 15 pin vga or DVI adapter. This would show the problem in the Vista driver for the monitor. I'm using A nvidia in the XP and the Vista box. Same problem with ATI 3450 HD card. So I'm back to using XP. Vista still is not ready.

you should exchange another one now. The firmware you have on it is for 22in only. The signal it sends to you video card for max 1680x1050 only. To confirm it you should try with another monitor with 1920x1200 then exchange out the T240HD ( do not reboot the system). You would see your T240HD would be able to display in the full scale ( 1920x1200). However, if you reboot your system the monitor would go back to its 22in firmware.

I did it myself.

Then why does is work properly with XP? The problem is with the code for Vista. Samsung needs to fix the driver for Vista, works fine with the same PC running XP. Load vista and problem occurs again.
May 11, 2009 6:46:56 AM

I have the same problem with my T260HD. I'm running vista with a radeon 4800. HDMI works great (1920x1200), but DVI doesn't. I can configure it to run at 1920x1200 in vista, but when I logoff/logon again the screen goes blank and stays blank. Plugging in the cable in another monitor and then in the T260HD seems to 'wake up' the display again. Dual link cable doesn't help.

Is there any conclusion on what the real problem is ? Is it the firmware or the Samsung monitor driver ? Anybody got this setup to work ?

Thanks a lot!

It seems there is actually nothing wrong with the monitor itself (the firmware seems to be correct, etc.), but that Vista somehow puts the monitor to sleep when it switches users. I replaced it with windows XP (after a small detour in Windows 7 that had the same problem), and everything works fine. I don't know whether the problem is the Vista support of the screen, or that it's a problem with Vista itself, but I got it to work.

Well there might not be anything wrong with your monitor persay as I don't know your manufacture date, plugin play ID etc...

Are you saying that if you use your monitor via Windows XP (64 bit or whatever you use) it works fine? And you don't have any issues whatsoever? And if you use Vista it somehow puts the monitor to sleep? How does it put the monitor into to this sleep mode? I never switch users as I am the only user on this PC.

Hey guys,

I just got a t240hd and am running windows 7x64 with 2 x sapphire 4870's in crossfire. If I plug my monitor in the dvi port after windows has loaded with another monitir, it works fine until i reboot. Then when i reboot, it gives me the windows 7 splash screen and then goes black after giving me the sounds of the welcome screen. Then i can log into windows but it remains black and asleep. I can even plug in my old monitor after this has happened and it remains blank. Should I try the VGA cable? What's the deal here?
June 4, 2009 11:33:16 PM

I have a t240"red rose" on DVI and with a HD4870 its fine at that, however its a sod for going blank :S
July 6, 2009 11:19:49 PM

I have a 4870 and a t240hd running now, Just fine.

However today i added a 2nd t240hd, which seems to be having the same issue you all are, however my wifes sony links up just fine at 1920x1200 on hdmi.

Very odd indeed is there better firmware?

As long as the video card and the cable can support the digital signal (DVI-D), you will be fine using either DVI-D or DVI-I cables. The T240HD says it requires DVI-D simply because it won't use the analog signal if provided (through DVI-A or DVI-D) unless supplied through the VGA connector.
