Windows 7: HDTV out display issues

HDTV out display issues

Hello, I'm having problems with windows 7 detecting my HDTV as HD on component. It detects the other display but will only let me display low resolutions. When I open nvidia control panel. It says it's hooked up via S-video not component. Does anyone know a way to disable windows display detection, to force it to detect the proper connection type, or any other method that will allow it to display HD resolutions.

There's some kind of software conflict going on I think. It will work properly about 20% and detect it as using component hook up.

I've been trying to solve this issue for the better part of a year, and it's very frustrating. I never had this issue on XP.

Your issue is mostlikly with HDCP. What is HDCP? I'm glad you asked,

High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed by Intel Corporation[1] to prevent copying of digital audio and video content as it travels across connections. These connections include popular ones like DisplayPort (DP), Digital Visual Interface (DVI), and High-Definition Multimedia Interface (HDMI), as well as non-popular or now defunct connections like Gigabit Video Interface (GVIF), and Unified Display Interface (UDI). It is commonly, though incorrectly, referred to as High-definition Copy Protection.

So in short you need to find the port on your tv that has the feature disabled. I have a Sony EX-500 and this is only disabled on HDMI port 1. All of the other HD ports have this feature. Basicly HDMI only exists because companys do not want you to make copies of movies. I guess they have never heard of DVD and Blu Ray Burners. As for the svideo, the computer is correctly displaying what is being used. The round port which you are mostlikey using can be used for svideo and compent.

If you have any other questions just ask.

I thought HDCP prevents you from playing HDCP encrypted content (DVD/Blu-ray) on non-HDCP devices. The problem is getting to TV to display in the correct resolution in the first place with just my desktop.

Every time I switch from Dual Screen to Single screen for w/e reason. I run the risk of the resolution being stuck at 800x600 instead of 1080p. It looks like to me windows screen resolution software is overriding nvidias control panel. I'll try to do things in the control panel and click apply and they dont apply, but when I try something in the windows default screen resolution it works. I think the default windows stuff isn't working with the drivers properly in 7 or having some kind of software conflict with control panel on my comp.
