XPS 1530 HDMI with HDTV

I had some movies on my XPS 1530, so I decided to connect it up to my parents Samsung 37 inch HDTV while I was home for Thanksgiving. This would be the first time I have every used the HDMI output jack on my 1530 and I have noticed some strange things. First, when I connected the HDMI cable my computer it detected the HDTV but every time I try to switch to it, either by FN+F8 or in the nvidia control panel, it reverted back to the notebook screen. The only way I could get it to work was by rebooting the machine with the HDMI cable plugged in. After it reboots, I can then change to the HDTV no problem. So why would I need a reboot to get it to work?

Second, after I finally get connected the only resolution that seems to work is 1280x720(720P). If I try to go any higher the picture on the HDTV will flicker terribly. I have connected my 1530 to other displays using the VGA connector and have gotten higher resolutions before, so what's the deal with the HDMI connector?

Background info:
XPS 1530 (Bios A12)
Fresh installing of VISTA Business
Video Driver - (laptop2go modified) 177.98

Thanks

 

First why do you have vista business. it does not come on that notebook. second, why are you using the modded video drivers. they only cause problems for what you are trying to do.

The reason for the resolution is that is likely as high as that tv goes.

 

As above

But on a side note I installed the modded .inf file and drivers, I want to get rid of them now but not sure how?

Anyone know?


Thanks!

 

Mart , just un-install the modded drivers and install Drivers provided by Dell Simple

 

If only I uninstalled via control panel and went to install the standard one's 178.24's on the Nvidia website and I get the error below?

Hence my stuckness...lol

 

Hold on I just realised what the problem is...lol

Do Dell offer Vista 64bit drivers for the 8600GT?

Can someone link me if so..

 

Being thick, got them

 

You might want to tell us the full specs of your notebook AND your TV, because 1280x720 might well be the max resolution of your TV. Makers generally do flaunt a TV to be HD, but neglect in many cases to include the resolution of the TV.

 

Laptopvideo2go (moded) doesnt really mean the driver itself is modified/tweaked. Only the nv_disp.inf is changed to make the original nvidia drivers installable on Mobile cards, thats all. Actual driver is as provided by nVidia.

@ Mart-XPS: However, installing DELL drivers might fix your problem, since DELL drivers are properly tested to work with your notebook, but they might not be the best drivers in terms of performance (because they are few versions behind nVidia's latest driver releases)

As I said above, you need the modified nv_disp.inf to install any drivers downloaded directly from nVidia, because they are ONLY meant for desktop cards. That is why you get that error.

You have to either install a different version from laptopvideo2go OR install the version available at support.dell.com

 

Install the original 8600 GT driver from dell and then try again

 

I actually ran into this problem recently with my TV and an HDMI connection. Apparently my TV (Westinghouse LTV-32w6) only accepts up to a resolution of 1280x720 over HDMI, but allows custom timings and resolutions over VGA, allowing me to use the full 1360x768 resolution of the LCD panel. Even using a custom monitor driver with Powerstrip wouldn't solve the issue.

Of course, every TV is different - just depends on your model.
