Nvidia 7300 HDMI to LCD - Resolution/Quality Problem!

Hi, im trying to connect my computer to my Samsung LCD tv but i am having problems with the resolution.

My gfx card has a HDMI output (is MSI 7300 series card) and i connect this straight into the tv. The screen comes up but the screen edges are cropped, and the display looks a bit naff to be honest.

I am running the latest drivers from nvidias website. On the nvidia control panel i set the output format to hdmi 720p (which is what my tv is). I then click set to native resolution of the samsung (which is 1360 x 768). I click ok, the screen looks much nicer but it is cropped.

I then reduce the resoltion incrementaly until i can see the full desktop, i am able to when i reach 1176 x 664, however the picture isnt quite as sharp as i would like, plus there is some unused screen space at the screen edges.

The thing is with the VGA input to the tv i can run it at 1360 x 768 and it looks very very good, apart from some slight tearing when watching movies and fast moving scenes.

Any idea how i can get the hdmi to work good? I thought buying an hdmi output capable card would avoid all this hassle, i wanted it to just be simple like plugging in an xbox to the tv and getting a nice picture!

Do i have to use tweak tools? I cant see an option (even with advanced mode) under the nvidia control panel to create custom resolutions.

Whaaaaaaa :(

thanks in advance
 
i dunno about the 1:1 mapping, good call though ill check it tonight.

i thought hdmi would work fine, how wrong i was! i dont understand the difference to be honest, xbox works fine in 720p i just wish my pc was as simple. The 7300 supports hdmi connection and HDCP also, i dont actually why the pic is so carp!
 
forgot to say im running vista ultimate and i dont think the current nvidia drivers are capable of overscan correction :((

AFAIK you have these options:
- Set the TV to 1:1 pixel mapping (if possible) or adjust the settings on the TV so that you get black borders around the edges at a lower resolution but that the rest is 1:1 mapped.
- Live with the overscan (depending on how much you miss)
- Use a lower resolution to get the full image (this will mean you do not have 1:1 mapping and it can be blurred)
- Install XP and use that.
- Get an external scaler (very expensive and might not work)
 
cheers dutch guy... dude you have a lot of posts!!!

im thinking this will be sorted in future driver versions? for the meantime i may just stick with the VGA i know i can get 1360 x 768 and it looks sweet.

Thanks for the help.

It won't be sorted, this is a problem with your TV's hdmi input that cannot be fixed.

As I said already there's a simple fix. Just use the VGA input.
 
I've been trying to do the same thing, I actually found that the screen looks perfect through vga cable to a 40" Samsung 1080p LCD TV.

One thing I noticed though was that when I played a game the FPS was capped at 15fps is that the tv or the connection?

Whats a 32" LCD TV which will work then?

I tend to get tearign when watching videos on my laptop through the VGA, havent tried it on my 7300GS yet.
 
Only LG LC2's can do 1:1 pixel mapping and native res over HDMI on 768 line sets. No other 768 line sets can do this (maybe other LG's).

I think the reason you get tearing is because of the 60hz refresh rate, with hdmi you are probably using 50hz which is in sync with the 25fps videos you are watching.

So you'll have to choose between tearing or decent picture quality.

You could also try 75hz if that's available which should stop the tearing. You'll probably need to force it in powerstrip though, and possibly fiddle about with the timings.
