Resolution issue when connecting to a PC

The LCD TV works well in stand alone mode, but when I try to connect it to a PC with a VDI cable, the video mode is not accepted by the screen (though properly configured for PC use). The only solution seems to start the PC in safe mode and set resolution to 640 x 480, which is by no means an acceptable standard for today use of a PC. Is there any way to use the screen connected to a PC with a higher resolution? Thanks for your ideas.

    Apparently no solution can be found for this problem, because 640 x 480 is the maximum (nominal) resolution for this LCD TV when used as a PC monitor. This intrinsic limitation is a serious drawback of the 20" 4:3 LCD. In the same series, a 20" widescreen also exists, with a much higher resolution (1280 x 768). The 15" and 23" LCD also have a higher resolution (1024 x 768 and 1280 x 768), respectively.

If the tv accepts 640 x 480 via DVI lead in safe mode, then as long as the tv is set to work in conjunction with the same resolution as your pc by the pc to DVI setting, it must be your pc's graphics driver that is the problem, as in safe mode the graphics vga driver only is loaded and not the advanced graphics options and resolutions, so enabling you to view on an external monitor. You should be able to right click on your desktop, then graphics properties and select either clone/dual or monitor. If this option does not show then you need to go into your graphics cards properties and ensure that an external screen or multiple display; is enabled, depending on your graphics driver.

Olevia LT23HVX screen resolution


what kind of cable are you connecting with? If you are using a Composite or S-Video cable perhaps you may want to use the VGA cable instead and see if that corrects the issue.

The scrren either says resolution is not supported (mode 1) or the screen wiggles and shakes (mode 2). A directly connected pc works fine. I am sending to a tv with pc input as the remote display


The QVS VBC5 video extender supports a maximum resolution of 1600x1200 @ 60Hz for up to 50meters (164feet) & 1024x768 @ 60Hz for up to 100meters (330feet).

Make sure your maximum distance of Category 5 cable from your source to your television is no longer than 330 feet if using a 1024x768 resolution. Try dropping the resolution on your source computer in Mode 2 to resolve the issue.

if you have a PC input to your LCD panel, connect the VGA cable at both ends (one to PC and the other to LCD TV), Only after the connection switch on the PC not before.
Make sure your Computer Display settings - Resolution not more than 1020x780. If so reduce and then try.

Philips 52'' LCD HDTV. Has PC Input Issue.


You will need to download and install the catalyst drivers and software for your ATI card from here http://game.amd.com/us-en/drivers_catalyst.aspx?p=win7/windows-7-64bit These are the drivers for the 64-bit version of Windows 7 and I believe that is what you are using. With the Catalyst software installed you can adjust the HDMI output to 1080p,1080i, or 720p so your TV will recognize it. Let me know if that works.

Samsung 27'' lcd tv for Pc Monitor resolution max is only 1024x768


Use a DVI (female) to HDMI (male) cable to connect your PC video card to the LCD TV. You will then be able to use the full resolution of the LCD TV. You will always be limited to the max resolution of the TV though, not matter your video card.

LCD TV and VGA output


The resolution and refresh rates have to match exactly to the TV for it to work correctly with the computer.

The newer computers are using much faster refresh rates by default. Their default resolution is also different.

Consult the manual for the TV and see if the computer's external monitor output can be set to match to what the TV exactly requires. Both the refresh rate and resolution are critical.
