720p not supported on VGA?

[Mark Kaine]

so I've been resurrecting my old (and very glorious) Athlon 64 x2 Windows Vista PC... as far I can tell it has only VGA as Video output (NVIDIA nForce graphics) and when I set it to 720p my TV (FUNAI 720P) says 'not supported' anything lower than 720p works tho, and I know this TV supports 720p for sure (over HDMI at least) 

 

So any ideas how to fix this? 

Do I need an adapter? 

 

I will also install a ATI X1950 GT later, maybe I have more options with that?

Either the VGA port on your motherboard or the VGA port on your TV doesn't support 720p over VGA.

Do you have another VGA device that you can test with so we can figure out which it is?

hmm..... its probably hardware end. I can do 1080 over vga fine.

Specs would be helpful. VGA can definitely do well above 720p.

Just over 1080p is the most commonly highest supported resolution that most VGA cables can do. (in other words your far from an issue using 720p on the VGA standard)

 

As another comment suggested your probably coming against a hardware issue my friend.

Can your TV accept an output of 1024x768, by any chance?

I see, unfortunately I don't really, but I have dvi - vga adapter, and I think also dvi - vga cable, or possibly hdmi - dvi... I just checked what I have right now without searching too much :

 

 

(the little one is a msi 'comanche' d64 - without vga port apparently!) 

 

the round port is S-video I think? maybe that would work, or the adapter? edit: just checked that's 480p lol, so maybe the vga-dvi adapter, or maybe vga-dvi-hdmi? Otherwise it's either the cable or the TV, or motherboard (though how likely is that?) 

 

well I also have my Asus mx 279H, but it's stashed away, and I'd rather not set it up at the moment - not a lot of space where I have the Athlon PC.

Yeah it's probably the TV, but not sure.

motherboard is (Asus, probably) M2N68-LA (HP prebuilt) 

cpu: AMD Athlon 64 x2

yeah, it does, but also 1360x768, and 1280x768...

I'm suspecting that your TV:

1. Doesn't like 720p signals being sent through a VGA output, at least concerning that PC. It could be outputting something that it's not expecting for VGA for whatever reason.
2. Your TV taps out at 1360x768. Most 720p TVs don't have a native resolution of 1280x720. Many of them actually top out at 1360x768 or 1366x768, while some older TVs top out at 1024x768.

If it's not bothersome and 1360x768 happens to work, just use that.

Almost figured, though it's weird if I plug in my PS3 over hdmi it'll say '720p'... but I guess the vga port is less 'optimized' for lack of better word. 

 

And I really would have liked to play at native resolution of the TV - which im now not even sure what it even is. 

 

 

But for the time being it's fine, I'm just testing stuff, maybe it'll change with a GPU, but looks this TV doesn't even have dvi, so I need to use an adapter. (which I remember I always did, but that was with a monitor.
