repost from Samsung 600 series owners's thread
I have a Samsung LN52A650, Dell Inspiron 518 and VisionTek Radeon 3450 card with a built-in HDMI port. When connected to the TV (tried HDMI2 and HDMI3 on the TV), the video card seems like it's not detecting the TV (even in forced TV detection mode). I verified that the cable is OK and tried 2 known good HDMI cables.
When I connect the TV to the video card using a VGA cable instead it works just fine.
I fiddled with settings and searched various forums and couldn't get it to work with HDMI. I have downloaded the latest drivers as well (using 64 bit Vista BTW) - and my TV firmware appears to be up-to-date.
I've tried rebooting the PC and shutting the TV on/off
Some odd things are happening though:
- TV always displays 'no signal'
- Computer monitor has native resolution of 1680x1050, but when I connect the TV by HDMI, the video card switches the max resolution to 1680x1200 (and 1680x1050 is no longer available)
- in 'Basic' mode in the Catalyst control center, it is telling me I can connect to either a monitor or TV (i.e. seems to detect the TV in this mode whereas it doesn't in advanced), but when I select TV, it does not connect
Any ideas? Thank you for any assistance.
