I just bought a Samsung LED monitor, BX1931N which supports 1366 x 769. What video card can best support this maximum resolution. I heard NVDIA 6600GT can support this monitor.

1920x1080 resolution is the starting point for HD video. If you have set your desktop resolution to that or anything avove then you should be running at HD resolutions. Maybe the image/video you are watching is not at a HD resolution, therefore it will appear distorted and streched (poor quality). To fully experience HD playback use video files and imaged that are at the 1920x1080 resolution and above.

This video card has a max resolution of 2560x1600, so generally any LCD or LED monitor on the market should work for it. If you want to have it work at it's maximum though I would recommend a bigger monitor or you won't be able to read anything on the screen. Personally I use a 32" at 1360x768, not the highest resolution but it is what I am comfortable with.

That means your video card and/or your monitor does not support that resolution. Check what the maximum resolution your monitor can handle. You can find that out by asking your monitor's manufacturer or looking up the model of your monitor online. If you're sure that the monitor can handle that resolution but its not working, try updating or reinstalling your video card driver.

max res is 720p.

Yes, if your video-card does not support the "native" resolution of the monitor, you'll get "fuzzy" pictures, until you replace the video-card.

Since 3/4 of 1920 is 1440, and 3/4 of 1080 is 810, does your video-card support 1440x810 ?

Since 2/3 of 1920 is 1280, and 2/3 of 1080 is 720, does your video-card support 1280x720 ?

You probably would not want 960x540. Correct?

Dual screen mode? You mean dual monitor mode?
But anyways, the maximum resolution that you can obtain on your Pavilion dv6t is 1366x768 unless you attach an external monitor. Even then, only the external monitor can go above 1366x768 resolution. You're laptop screen will remain at 1366x768 max.

high resolution is supported by high resolution monitors or LCD no matter what type of Video card are you using so first check monitor compatibility with the resolution

Hi, I noticed you posted this same problem again. Here's the answer from the first post which should answer your question.

The maximum performance of your video card is limited by the hardware you attach it to. In the display properties of Windows, your highest resolution is 1280x1024 because your monitor is not able to go any higher than this. This resolution is a typical maximum for a 17" monitor. Some 15" can do this, and some 19" can do this. In order to get a higher resolution, you'll need to get a bigger monitor with a higher native resolution. For example, a nice 24" monitor can only do 1920x1200. The video card can go higher, but it's limited by the monitor. 32bit color is your highest setting - that's 16 million colors. Your video card's 1GB of RAM only determines how much rendered data (usually 3D) it can store and move at any given moment, which is related to but not determined by your screen resolution. That's a very nice card - you should be able to get very good frame rates, color, and performance out of 32bit color and 1280x1024. If you want a higher resolution, you'll need to get a bigger monitor.

The problem is the cable connection to the video card.
When using the DVI output of the FX 5500, the maximum screen resolution that you can select is 1280 x 1024.

But, if you use the Analog (VGA) output, the card will support resolutions up to 2048 x 1536, which should be ok.
