Yeah I played around with the NV CP and made sure my resolution was correct and my frequency was correct too.

I am guessing the off-white color has something to do with the way the actual HDTV processes the information. Going to mess around with that tonight.

This is going to depend on your tv. Not all TV's were made with PC's in mind and thus won't necessarily allow for 1:1 pixel scaling. Worse, some force overscanning which means you won't see the outer edge of your screen. I'd look at your TV manual, or maybe google search to find if it allows for 1:1 pixel scaling.

In the shops they seem to refer to this as HD-ready, as opposed to True HD. At least they do in the UK.
Why not? If the refresh rate is at 60Hz then it is scaling it down, but many times if you choose the higher resolution it will automatically down it to 30Hz.

Ah, I kinda see what you're saying. I'm no too clued up on how that side of it works TBH.

Yeah, didn't think of that. Your colour temp is probably set to 'warm' in the TV's settings.

I'm not sure how it works and I've been trying to find more information regarding it. I just know that when I go into the control panel and select 1920x1080 the resolution on the TV obviously changes to it and the refresh rate is set at 59hz. In games there is a noticeable difference when going from 1280x720 to 1920x1080 as well. Even just going into the control panel and selecting the HD signal format to 1080p it works.

Text becomes pretty damn tiny and hard to read at this resolution sadly. Otherwise the Samsung LN37A450 is a damn good TV. I can only imagine the newer models are better.

Your TV is probably scaling it down.

I doubt they sold you a 1080p TV although it's labeled as a 720p lol.

I know it's not a 1080p TV. I guess what just kept throwing me off and what was my point is that in the Nvidia control panel it states the signal as 1080p even though what the TV is actually displaying is 1080i. The TV is just tricking the graphics card so that it sends out the signal but converts it without the source knowing.

Hello all,

I've successfully hooked up my PC(DVI) to my Sony TV(HDMI) and I'm pretty happy with it.

I've got a 256MB NVIDIA GeForce 8600 GTS graphics card.

While watching movies on my tv, and there is alot of motion, there is a tiny bit cracking in the picture.


Any ideas what the cause of this is and how to fix it?


Thanks

What kind of "cracking"? I'd guess you've got sharpening turned on on your tv - so just turn off any settings meant to improve the image quality of your TV from the TV's menu.

it's almost like a lag, when you see a person running fast on the tv screen, you will see a very slight lag in his legs. it's like its trying to catch up?
