When I connect my Apple Powerbook G4 17" to the VGA input on the TV, it just says "Mode Not Supported" on the TV... at ANY resolution setting...

I previously had a 720p Samsung LCD TV, and it worked fine at 1360 x 768..

I just cant get ANY picture at ALL now on this new TV... its the LA40F7 model.. the new one..

Any help would be greatly appreciated. Are there any known issues?!?

I'm using the powerbook's DVI output... which runs out to a DVI > VGA adapter... the one that came with the laptop from apple..

it worked a treat on the 720p screen that I returned.

Seems like a problem with the motherboard inside the tele have a tech guy come check it out. Or if your going to return it then take ur laptop and try it at the store.

dang it. OK will do. I'll also call Samsung, in case there is some sort of work around.

Check your refresh rate. It needs to be 60 hz not optimal or some other setting.

Have you tried checking the display properties of your secondary monitor in videocard software.And if you can try vga to vga connection from a home computer if you have one.

hey guys...

yeah my mac says 60Hz as the output on the display settings

when I connect the LCD to the computer, it detects it as a 'SAMSUNG LCD" and correctly displays all the various resolutions I can set it to... but none of them work...

I only have Computers with DVI outputs unfortunately. But even still.. the other 720p Samsung LCD worked fine with this type of ouput using the DVI > VGA converter cable..

I spoke with Samung, they have no known issues... they said to take the laptop up to the retailer and plug it in there and test it on a model in store... Could just be my TV, as already mentioned.

Does your PowerBook have a graphics setting for 1920x1080, or are you trying to use a lower setting?

Your previous TV had a lower native resolution.

What graphics settings are listed in your Samsung's manual for computer hook ups.

I'm trying to output at ANY resolution, but ultimately 1980 x 1080..

my laptop supports that res, and the manual for the TV says that 1920 x 1080 @ 60hz is the corrent setting

Yeah, take it to a store with the same model. Also try some other model. Then you'll know.

OK, here's some info

Same problem at the store. In fact the SONY's would work, but only up to 1360 x 768.

DVI > HDMI worked at all resolutions up to all but 1920 x 1080... at which point is overscanned the image.

So I went home and though Ti would try my big desktop computer.

And BOOM, it worked. Detectedc the LCD and displayed 1920 x 1080 first go.

Then my computer went to sleep. So I woke it up... and DOH... 'mode not supported' displayed again. The only way I could get it to display the PC image again, was to repeatedly press the 'PC' button on the TV's remote... after a few goes, it eventially picked up the signal and worked.

I'm guessing this is a firmware issue in the Fseries Sammies..

Once i got the picture working at 1920 x 1080, the displlay is fantastic. Obviously sitting at the lounge, its hard to make out some text, since the pixels are so small.. but you could EASILY use your TV as a work display if you sat close to it.... But for what I want.. which is to be able to watch high def footage off the mac... it works perfectly.. just gotta sort out the firmware issues.... and.. get my laptop to work.. so I'm gonna call apple and ask them if the graphics card needs a firmware update

The new Aluminum Mac Mini just released in June 2010 has a HDMI port - quick and easy connection to my 48" Samsung LCD HDTV; perfect picture/desktop right out of the box. No hassles. Hats off to Apple for this long awaited feature!
