Why do i keep getting the Mode Not Supported Error???

by jokerfwb / March 8, 2009 11:17 AM PDT

I have a custom built computer. The graphics card is a Nivida Geforce FX 5200 i have the updated drivers for it. I have a Samsung 32 HDTV model number LN32A330J1D. I have my computer hooked up to it with a normal computer monitor cable, RGB i believe is what it is called. The problem i have is my TV only supports a handfull of resolutions the highest being 1360 x 768. When ever the computer is hooked up to the TV and i restart it changes to 1280 x 1024 and the TV says mode not supported. So i have to get out my LCD monitor change the Rez setting back and then switch the cables and all is good. Now when the computer is pluged into the LCD monito which is a Starlogic widescreen HD20W and restarted it stays on the rez it was set at. What is happening when my computer is hooked up to the TV??

Refresh rate

If you have the resolution set and still get mode not supported, make sure that its also set to 60hz for the refresh rate, if its not 60hz that can also cause mode not supported.

Mode not supported error

Ya i checked that and it was set at 60. I have figured away around it though. I just went out and bought a DVI to HDMI cable and all is good now. I would like to know why it was switching when hooded up through the RGB cable. I think it has something to do with the TV maybe it needs a Firmware upgrade.

Auto Detect
by Samsung_HD_Tech Samsung staff / March 16, 2009 2:25 PM PDT

jokerfwb,

I'm glad you found a solution. I'm not sure why that was happening. I was thinking that maybe the video-card has an auto-detect for the resolution and it's not connecting right up. Mode Not Supported is a generic error message that basically notes that the resolution coming in isn't supported - that is, able to be processed evenly onto the screen. These are usually resolutions that would look bad as a result on the panel it's being shown on.

The cable I think you were trying to describe is usually referred to as a 15-pin connector, D-Sub, or the generic "VGA" or "monitor cable". RGB refers to a component connection with the Red Blue and Green jacks, but most computers don't have that output.

Welcome to the forum, and again, I'm glad you were able to find a solution.
