First, attempt to use another input on rear of set if possible, if no luck, contact LG tech. I had to replace main pcb on two of those for similar problem. Good luck, Russmann.

Ibm thinkpad wont connect to LG TV


Lower the screen resolution to 720 dpi.

Another issue is the reference to RGB. Is it the 3 cable (YPBPR) or the standard 15 pin VGA? You may need a converter.

Trying to hook my home PC into my LG TV gets me the message Invalid Format, what can I do to get the signal or can i use this tv for my monitor with a dell PC


Connect VGA (D-sub 15 pin) cable from PC to TV (RGB PC) input jack. Connect audio cable from PC to TV. Set screen resolution on PC to be compatible with TV, such as 800 X 600 or 1024 X 768 etc. Select on the TV, the PC INPUT using the TV remote when ready to use as monitor.

Under PICTURE on the TV select SCREEN (RGB-PC). You can AUTO-CONFIG or you can set resolution manually to the same you set PC to. Other adjustments can be done here as well to get optimum picture on TV from PC.

I have a Samsung Series 6-650 LCD TV (Model # LN46A650A1F). I am trying to connect my Laptop to use the TV as a monitor and have done everything to make it work, using a VGA/HDMI cable, but the TV refuses...


Why do you use VGA-HDMI cable? This TV works fine with VGA cable - it has VGA plug.
Or if your notebook has DVI output, then you can use DVI/HDMI cable and connect it to the TV to plug named DVI/HDMI (only one HDMI input is marked as DVI on TV).
I suppose that over HDMI the TV supports only some standard resolutions, but over VGA it supports almost every resolution laptops use. You can find supported resolutions for each input in the TV manual. Try setting the same resolution on the laptop.

LG LCD Monitor won't exit Power Saving Mode


Does your desktop/PC display show anything before the monitor goes into power save mode? If nothing comes up, its possible that you have a loose VGA connection or that your video card/motherboard are defective in some ways. Try using a different monitor.

If the other monitor works fine with your computer, try changing/lowering the screen resolution. If in XP right-click on the desktop and go to Properties, and select the tab for display settings and adjust the resolution. If in Vista/Win7, right-click the desktop and select Screen Resolution/Display Settings and adjust it there. Then check and see if your LG monitor works on it.

If the other monitor also doesn't show any display, most likely the problem is either with your video cable or your PCs video card/motherboard, not the monitor.

Hope that helps. Good luck

Pc to tv


Try changing the resolution on you computer. That TV may not handle the current resolution setting. You may also have to do something on your computer to turn on the rgb output.

Blurry and shaking pictures on LCD


refresh rate, likely
try to adjust to a compatible rate. the monitor manual will give you its compatible rates. the video card should have that rate available. if not, you may damage the monitor with the wrong rate.
stop and try another monitor that has a refresh rate available on your video card.
good luck
