Hello,

Can you help me get the maximum resolution from my monitor? My graphics card's 'Calalyst Control Center' shows a max reported resolution of 1920x1200. However, the instructions for my monitor say 'The optimal resolution is 1920x1200 via VGA input and 2560x1600 via DVI input.'


  • I have a Dell 3008WFP 30 inch monitor that I bought two years ago.
  • My PC is a Dell Inspiron 620s, Win7, with a 'AMD RADEON HD 6450' graphics card that has 1GB memory.
  • I am connecting my monitor using a HDMI Cable.

I have tried using windows software and the graphics card's software to get the desired resolution. This has left me slightly confused and I'm still at 1920x1200 resolution.

I tried using a DVI cable, with the same results.

The monitor instructions do say to use a dual link DVI cable, which I do not have. I bought a HDMI cable instead, as I thought it would be at least as good, whilst keeping a DVI port free for my other monitor.

Do you think it's worth buying a dual link DVI cable, hoping that my HDMI cable is the problem?

"The Digital formats are available in DVI-D Single-Link and Dual-Link as well as DVI-I Single-Link and Dual-Link format connectors. These DVI cables send information using a digital information format called TMDS (transition minimized differential signaling). Single link cables use one TMDS 165Mhz transmitter, while dual links use two. The dual link DVI pins effectively double the power of transmission and provide an increase of speed and signal quality; i.e. a DVI single link 60-Hz LCD can display a resolution of 1920 x 1200, while a DVI dual link can display a resolution of 2560 x 1600."
