24 inch Sansui TV being used as computer monitor. Changed resolution, getting not supported message. Need to return resolution to acceptable limits but cannot get back to control panel to reset. What is correct resolution for widescreen 24 inch monitor?
SOURCE: resolution issue when connecting to a PC
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.
SOURCE: "Not Supported Mode" Message...
Your tv does NOT support any higher than 720p res.
Is your cable box set to this? If not, and it is set to 1080i than it would explain this, and is also a common problem with computer(vga) connections even with monitors. To see the current resolution the box is set to hook up a yellow jack to the to from cable box just to get the picture back long enough to navigate to a setup menu and lower the resolution back to the highest supported which is 720p
SOURCE: Picture is not centered on monitor leaving a 2 1/2" black border on Philips LCD
I have a Philips 30 inch LCD and solved the problem by using the circular arrow button on the TV remote. Pointing it at the TV and clicking "right" (3 o'clock on the button), the picture moved right. Same thing on for "left". Worked for me.
SOURCE: Mac Mini - Signal is not compatible with this intput
Can you change the signal format in the display settiings? 1080p is the native one on your monitor, try difrent ones if availabe. also test difrent resolutions.
SOURCE: VG4 mode on Insignia 19" widescreen LCD wont accept computer
go to your control panel of your computer (using a different monitor obviously) and change your screen resolution to 640x480, 800x600, 1024x768, or 1440x900. any of those resolutions should work. also go to advanced and make sure it is set at 60 herz.
