NVidia Cards and Vesa modes

I am looking at purchasing a new card for this system. Currently looking at the Zotac 750 Ti, seems to be a decent card. What I would like to know is what Vesa modes it supports. I am having some difficulty finding this info online.

If anyone has this card can you post the results of "hwinfo --framebuffer" here? I would be especially interested if the card supports 1920x1024.

Thanks I see it now, I actually looked at this page and missed it. Maybe terminology mismatch in my head, sort of. So when we are taking vesa modes for frame buffers we are talking about the "Maximum VGA Resolution 2048x1536" line, where the "Maximum Digital Resolution 4096x2160" would be your maximum once the drivers are loaded.

That link is not nearly enough to answer MikeW's question. It has some very generic info a on 750Ti GPU and that's all. The VBIOS is highly card specific, it depends on the card manufacturer, and I wouldn't be surprised if cards from the same manufacturer containing the same GPU had different VBIOSes, for example if the card comes in many flavors, like overclocked and non-overclocked variants.

The only one who could answer MikeW's question is someone with the exact same Zotac card, an info MikeW hasn't even provided (as said before, there might be multiple variants containing a 750Ti GPU). The chances that another Arch user has the exact same card are quite low.

If I may do some guessing though, based on my experience with Nvidia in general, and having an old Zotac card (GTS450 GPU, yeah, quite old ), the requested resolution is highly likely not there. My card only has 1280x800 as a widescreen resolution, the rest are classic 4:3 resolutions.

So when we are taking vesa modes for frame buffers we are talking about the "Maximum VGA Resolution 2048x1536" line, where the "Maximum Digital Resolution 4096x2160" would be your maximum once the drivers are loaded.

No, both of these refer to native modesetting (so when a driver is loaded), *not* VESA. I doubt any online documentation, especially generic docs like that, will have information about VESA resolutions in the VBIOS. You'd have to ask Zotac directly, but somehow I doubt the person at the other end doing customer service would even know what you're talking about .

This is unfortunate, but not surprising. When I tried to get this info from the clerk in the local store he looked like he might be having a stroke. I might just send a message to Zotac and see what happens.

That being said this is not a complete deal killer, I was just hopping that this info would be readily available but it looks like its not.
This is the exact card I was looking at BTW, a bit of an upgrade from the current GTX 260, and half the power use, possibly some lower heat output too.
