How can I get my Mac pro 1,1 with Radeon 5750 to drive LG ultrawide LG29UM65???

I bought this monitor and to my dismay, my mac is stretching the resolution to fit the screen. I understand that this is due to the HDMI's inability to display over 1920x1200. I've read about other people's workarounds using adapters for MBP's on here but haven't read anything about the limitations of an old mac with this particular card.

Can I do anything with this setup or should I buy a new monitor or a new video card? Also, keep in mind that eventually I would like to run two of these as a dual screen setup for a DAW.

Thanks in advance!!!

What type of ports does your 5750 have ? If it has a DisplayPort or a DVI port , then maybe you'll get better resolution choices using that instead of HDMI . DP and DVI are the preferred interfaces for the cMP . I would just get a regular DP or DVI cable and not mess around with adapters .

Thanks for the reply! The card has (2) dvi, (1) HDMI, and (1) display port 1.2.

This is rather troubling to wrap my head around. Is there any chance that this would work for at least ONE of the ultrawide's.... also, the monitor has (2) HDMI inputs and that is it.

This would go from my DP 1.2 and I could use a typical HDMI from there to the back of the LG. Or so I would hope.

I looked at the NewEgg description of this display model and it says you have a two HDMI , one DP and one DVI port .

Did you get a very low end inexpensive version available from only one retailer, with reduced features ? They sometimes play this trick .

Oops, its this... ATI Radeon HD 5000 1024 MB. I was way off although I was right about the outputs I think.
[doublepost=1457826660][/doublepost]Okay so I did more looking around and I am pretty sure this is what I have, a Sapphire Radeon HD 5770.

Solved. I bought a dual link DVI cable from Radio Shack and then added a DVI-to-HDMI adapter going into the tv and all is well. A cable similar to this is what is needed.

This should work for a dual monitor setup as well because the card has two DVI outputs. I hope this helps someone else.
