PC on TV

[Spekkio]

i just got a new acer aspire revo 3610 nettop with designs of hooking it up to my television via HDMI. unfortunately when i do that, all 4 sides of my image are heavily clipped off. by using the ion control panel, i can get it all to fit on screen by slashing the resolution down to 1200x660 but naturally reducing the resolution of the screen by such a significant sum makes it look rather ugly. the display is a 720P capable TV, so i can't comprehend why i should be unable to get it to display at 720.

by hooking it up via vga, i can get it all to fit on screen (oddly at the resolution of 1360x768, which i can't figure out where that slightly higher number comes from...) but that's just an analog signal and i'd rather use digital if i can figure out what's causing the problem. has anyone experimented with similar setups or experienced similar problems with any advice on a solution?

The two things I can think of are to either try a different driver (maybe even older than what you have) or if the driver supports it to use scaling. I'm not sure where scaling is in Nvidia's drivers or I'd give you instructions on finding that.

It's not the computer in all likely hood. I had the same problem with my TV until I used the dot-by-dot aspect ratio option. There should be an option in your TV somewhere, what it would be called I don't know.

I had the same issue when I went to using my onboard HDMI on my living room PC. It was a scaling issue - the default settings (Radeon HD3200 in this case) had it taking up something like 80% of the screen. Over VGA it was always full-screen with no tweaking. I had to install an actual version of Catalyst instead of just using the driver Windows 7 included, then find the actual control (which is rather stupidly placed, IMO), but once I did it worked like a charm.

I'm not exactly sure where this would be in the Ion drivers, but I would say that it's what you should look for.

I think I've also seen dot-by-dot referred to as 1:1 if it's the same thing I'm thinking of.

"1:1 Pixel Mapping"?

Yeah, I'm pretty sure that's what you're looking for. Pioneer likes to call it dot-by-dot for some strange reason.

i started digging based on what you said in the thread (much better springboard words than "HALP! MY TEEVEE IS CUTTING ME OFF!") and discovered this thread. it seems like it just won't work via HDMI on my samsung screen, though if i'd chosen another mfgr of TV i'd be fine. has anyone played with this setup on a samsung tv specifically and has any insight? the thread i found is here: http://forums.nvidia.com/lofiversion...hp?t78822.html

Just adding that most, if not all, 720p TV's native resolutions are actually 1366x768, and NOT the expected 1280x720. The TV then up scales the 720p image to fit the entire screen.

As mentioned, the issue is very likely due to underscaling by your laptop's video drivers. I had the exact same issue with my Samsung LCD TV with two different Radeon cards, and the fix was to adjust the scaling using CCC. I would think that NVIDIA drivers would have a similar option in their control panel somewhere.

I use a samsung, and what I do to avoid part of the picture to get cut off , is to play with the P.Size button. This is what works for me, hopefully for you too. I use the Just Scan setting for my laptop. For HD TV i gotta switch it depending on the channel.

Try this if you haven't my computer is hooked up to my tv using dvi/hdmi adapter and the bottom would get cutoff in 16:9 mode, set it to Just Scan and it worked perfectly.

when i hit the p size button, my TV only switches between 4:3 and 16:9, there does not seem to be a "just scan" setting unfortunately.

Yeah actually stumble upon that with a lower res laptop today. I guess the just scan is left for those that can output higher resolution than the TV. sucks...
