Hey all, i just hooked up my dell to my 52" tv. I used a dvi to hdmi connection and the image is great. However, now i only have one screen resolution available (640 x 480) but my screen cuts off portions of the desktop. So if i maximize a screen part of it is missing in all the corners. Before, i had it hooked up through s-video which allowed me to have 2 resolutions available, but with the hdmi there is only one. any suggestions? thanks!

Hi ehstraub, and welcome to Geeks to Go!

I'm going to start you off with the basics...

What type of video card do you have installed? I'm looking for the make and model.

In addition, have you updated your video drivers recently? Sometimes updated drivers add screen resolutions as well as other bug fixes, especially if your card was built for this type of output.

If are are unsure about what type of card you have installed, please reference the instructions I have provided below.

Items in blue which are underlined are "clickable" and provide more information about the process

Download and install Everest Home Edition

Run the program and click on the plus (+) next to computer then click on summary

Look through that report until you see the Display category. I'm looking for your Video Adapter.

With this information handy, I will be able to assist you in finding resolving this issue.


Please post the make and model in a reply to this message.

This installation is absolutely harmless, and is only providing us with an audit report of your system's components.

If you have any questions, please let me know! :)

Hey, thanks for the response. I updated the driver and that allowed me to change the resolution, which i guess answers my question. But the screen still does not fit the TV exactly. Like the task bar is half hidden and there is just basically a square that cuts off 1/2 inch from all 4 sides. And i tried to change the aspect on the tv, and when i did the small one, The screen was black all around the desktop, but there was still a section missing form all 4 sides of the screen, just kinda seems like the screen and video card are not in agreement with the size of the tv screen?
Umm, it is a dell 8300 with a nvidia geforce 7000 video card.
thanks!

Excellent, so it sounds like we just have some minor tweaking to work on...

This issue is known as "overscanning." I'm hoping we can fix that easily.

Is there an "auto adjust" feature on your TV? Sometimes using the "auto adjust" feature will fix it for you. If you have your TV manual handy, this would be a good time to check the appendix for it. Also see if it has anything about using the PC as a video source.

Also check your TV menu and manual for something called a "Just Scan feature." I've heard that this helps some people as well.

In addition, please look for any reference to "HD Size" settings. Some TVs have more than one size, and that may fix your issue right there.

If you don't mind, please provide me with the make and model of TV you are using. I can search the manual online for you as well. Two sets of eyes will work better than one.

Good luck! :)

If you press the Menu button on the Remote, move the arrows to the "Zoom Adjust" option and see if that can help at all.

Under the Picture submenu, it has Normal | Set at the top. See if you can move that around a bit as well.

I'm still looking into it, but see if these help.

Well I'm going through some different documents here, but I'm curious...

Do you have the NVIDIA Control Center/Panel installed?

This application normally comes standard with updated drivers, but that's not always the case. I'm thinking that this application will allow you to customize the signal you are sending out, and possibly fix the issue by creating a custom resolution.

Please start by letting me know if you have this application installed. I will then instruct you on how to create a customized resolution.

Hint: The easiest way to detect if this software is installed is to expand your tray next to the system clock by clicking on the (<) arrow. If you see the NVIDIA logo, double click on it and let me know.

Ok so the menus offered from the remote didn't work out so well. How about the NVIDIA Control Center or NVIDIA Control Panel I mentioned above?
