A Logitech Quickcam can take still images and video. Make the most of your webcam experience by setting it to take the best pictures possible. Here's how.
Double-click on your Logitech Quickcam icon. This is generally one of your desktop icons. You can also click your Start menu option on the lower left of your screen and choose it from your list of programs. Click "Camera settings" on the right of the new window that comes up. You can also get to the camera settings by clicking "Quick capture" and then clicking the arrow on the far right. Choose which settings you want to work with first. You will have the option of Video and Audio. The video option controls the picture while the audio option controls the sound. Go back to your main window and click "Quick capture." This will activate your webcam and allow you to view what it will look like as you adjust the different settings. Move the bar back and forth on the Brightness, Contrast and Saturation. Do these one at a time while viewing the image on your webcam until you are satisfied with the quality of the picture. Click and un-click your Low Light Boost and Color Boost options to see which, if either, is needed to make your picture quality what you desire. You can turn these on and off based on the lighting of the room at the time. Click on your Audio option once you are satisfied with your picture quality. A check mark will appear if the volume is at a good level. If you choose to reset it, click the Configuration option. Follow the steps on the Configuration Wizard once you select the Configuration option. The wizard will walk you through testing the sound on your webcam to ensure quality during live webcam chats. Hope this helps.
Hi - I have some suggestions. The following factors effect picture quality:
1. Source (because LCD TVs have much higher picture quality than traditional CRT "Tube" TVs, the worse your source material, the worse it looks on a LCD TV).
DVD and Sky/Digital TV should look excellent on this TV when connected with a good quality Scart lead (nothing too expensive, but a Oxygen Free Copper Gold lead may help) directly into one of the TV's Scart inputs (avoid using "switching" boxes for multiple equipment).
Also, bear in mind that this is a HUGE screen (40 inches I think) and will REALLY show up bad source material.
The best advice I can give is, if you have HD-ready equipment use HDMI connections for everything (ideally with an HD-uplscaling DVD player which will "improve" the quality of standard DVDs on the TV - I recommend models by Philips) and check that you are in "Movie" or "Cinema" mode on the TV.
Make sure that all of your equipment, like your Sky digibox, is set to 16:9 mode (not 4:3) aswell to preserve the true widescreen aspect ratio.
Hope that helps!
The intermittent horizontal line is cause by a loose solder connection in the vertical amplifier IC.
The IC is mounted on a heatsink nearby or around the flyback transformer.
The way to fix this failure is to add fresh solder where you see some brown spots on the circuitry that were cause by components getting hot.
Yes it sounds very much like it is simply in need of a tuning. Also if you do not feel comfortable repairing yourself, this is a very simple fix that can be done at most any electrical repair shop and usually doesn't cost too much.
It may be that your audio cables are poor quality. Try getting some higher quality cables to run your sound and see if that helps. If your system has optic outlets then these are best. Coax are better than RCA as well. If only RCA, then just try buying some higher quality RCA cables. Good luck!
