    Help with screen display


    Hi

    I bought a new computer yesterday (desktop) an firstly during the setup process found out it didn't have VGA port so I couldn't connect my screen to it, I have today been out and bought an HDMI to HDMI cable and connected our HDTV to it. After setting up everything seemed to be going fine but when the desktop was showing both the left hand edge and the bottom edge of the screen were off the monitor. I have managed to slightly adjust the screen via the TV menu so that I can see the buttons but when I open anything I am now missing the top bar as the window opens up at the top with the top 1/2 inch missing.

    I am curious as to how does it know what size screen you have it looks about in inch too small but if I buy a new bigger TV will the same thing happen, why does it not just fit to the screen.

    Thanks for your help

    In some TVs pressing the picture size button on the remote can help fitting the image on the screen. In others, there is an "auto adjust" option in the picture menu when input is set to RGB/VGA/PC

    I don't have a picture size button. The only options in the menu are horizontal and vertical but they just move the picture about on the screen but do not change the size.

    The picture size is the one changing 4:3 to 16:9 or zoom or smart etc. In computer input it resizes the image and one of the settings fills the screen exactly.

    its overscan issue by the output port of your computer - you should be able to fix it via drivers. if not - try to set TV on "PC" or "Gaming" mode - whichever it has. this should add you the extra 5% in horizontally and vertically so you can see the screen correctly.

    auto adjust has basically nothing to do with this - its the mode VGA is accepting the signal in (most of the time it says "universal" so you have to configure the output and data you feed to your TV if theres no PC/gaming mode available)

    overscan parameter on/off on TVs / monitors can only be used when you have HDMI-input chosen

    When using the PC input of your TV it should take care of overscan automatically, so you can see the whole picture. I'm currently using a Sony Bravia 16:9 LCD TV because my old CRT monitor died. Almost every time I switch it on the picture has black borders top and bottom because of incorrect scaling. I just press twice the picture resize button on the remote until I see message "full screen" and the picture fits the screen perfectly without cropping or black borders. In another no-name 15" LCD TV the same function is performed if I select "auto adjust" from the menu while in PC input. As I said it depends on the model. See your manual for more details.

    actually no. theres differencies. and if you plug it into a "wrong" HDMI input, then its not "automated". most of the TVs have HDMI (RGB/DVI) -input and then just HDMI -inputs. its due to a being "universal HDMI" which is meant for computers - no overscan issues or as you said, automatic correction for it.

    most of these HDMI -inputs (Sony, Samsung, LG, Philips, NEC etc) have to be configured to be this "PC" -mode.

    1920x1080 = computer resolution
    1080p = video resolution

    on video use (ps3, ps4, xbox, blu-ray players etc) the overscan is already popped into the output format

    dunno if this made any sense for you tho :P

    I was talking about analog VGA or D-SUB or PC (RGB) or whatever is called input. Not HDMI. HDMI is digital and should adjust automatically. In worst case you may have to manually change the resolution to 1280x720 (for HD-Ready TVs) or 1920x1080 (for Full HD TVs). After matching the native resolution of the TV it should fit the screen with a perfectly clear image.

    once again - HDMI isnt adjusting itself always automatically cause of things i mentioned its due to TV setup and due to difference between computer resolution and video resolution

    Yes, you may not get a perfect fit at once, when you switch to HDMI input, but if you set the TV's native resolution, you could then make it fit from the controls. We are saying the same thing. I would be easier if it was fully automatic, but this vary with TV model.
