Folks,

This is the first time I have connected a PC to my LG 42 LCD TV. I run other devices to it through an Onyko HDMI system such as PS3, DVD player, Sky HD etc.

I built a Mini ITX system using an Antec ISK300-150, ASRock E350 mobo, 8GB Kingston Hyper-X memory, OCZ Vertex 3 SSD, Windows 7 64-bit.

Anyhow, it all runs fine but I notice in Windows, half of the task bar is chopped off at the bottom. Now all other devices display fine so I tried to look for settings on the GPU within Windows to change size of screen but can't find anything. My TV is set to 16:9 so I cycled through available settings and found "Just Scan". When choosing this setting, it displayed correctly.

However, the next time I reboot (next evening), it reverts to 16:9 and I have to manually choose "Just Scan" in the TV settings to display correctly.

Has anybody else had this issue? Is there a solution other than what I am doing? It's not really a major issue because watching films is OK, just an annoyance.

The edge of your picture is being cut off overscan. TVs by default stretch an image by 5% (overscanning) which goes all the way back to CRT with analog TV days when displays didn't have fixed pixels like modern displays. For some reason it's still default today :confused:. What you done is exactly the right option, use your TVs 'Just Scan' option, which turns off overscan (ie. 1:1 pixel mapping.) My LG TV remembers the setting however. Have you tried updating your TVs firmware?

Thanks for the info - useful to know and glad it's not specific to me :) I haven't updated the firmware, not sure how to. I have an LG 42-LD450, got it about 15 months ago.

I had the same problem (LG TV not remembering overscan). I asked their support department and they said there was no way to get round it using the TV hardware.

So I adjusted overscan in my Radeon's GPU settings. Since your mobo has built-in Radeon graphics, then I imagine you might have this option too.

Ok - thanks. I'll take a look in the ATI control panel. It's an onboard GPU, part of an ASRock Mini ITX E350 mobo. It is a Radeon 6310.

BTW - I used the display drivers that came with the CD/mobo, think it was dated March 2011. Is there any harm in downloading the latest from ATI or does the onboard GPU require special drivers?
