It would appear that you're 0 'fer 3 on plugging devices into that TV. Why would you risk a 4th (even if it is used) when all signs point to a defective HDMI port on your TV?
This is a long, detailed post meant for anyone who has the time to read it and wants to try to figure it out.
I restored the SSD in my laptop but the HDMI port still wouldn't work with the TV set. I was using two 10 foot HDMI cables while testing. As a last resort I tried a 6 foot HDMI cable. The laptop's HDMI port displayed on the TV set!!! So the laptop's HDMI port isn't toast after all. I tried a 10 ft HDMI cable again and it worked. Go figure.
Here's what I don't understand. Maybe the sleuths on this forum can figure it out:
TOWER PC RUNNING WIN7:
1. PC's integrated HDMI port initially worked with a monoprice 50 ft HDMI cable to the TV set.
2. After about a year?, the 50 ft HDMI cable stopped working.
3. Replaced it with a 30 ft RedMere HDMI cable from monoprice and it worked.
4. After maybe 6 months (not sure exactly), the 30 ft RedMere cable stopped working.
5. Tried a 10 foot HDMI cable since it barely reached from computer to TV across the living room floor.
6. It wouldn't work.
7. Pronounced the integrated HDMI port dead.
8. Installed the used HD4350 card that I already had.
9. It worked with the 30 ft RedMere cable to the TV for maybe 6 months.
10. Went on a 10 day vacation.
11. Upon return, the 4350 HDMI via the 30 ft RedMere HDMI cable wouldn't work.
12. Tried a 10 ft HDMI cable to the 4350 but still no work.
13. Reinstalled the Gigabyte driver for the 4350 but still no work.
14. Installed the latest AMD driver for the HD4350 from the AMD site and it won't work.
15. Tried a 6 ft HDMI cable to the TV. Still no work.
16. In steps 13 and 14, the Catalyst software icon does not show in Win7's notification area. Nor does the Catalyst show in Control Panel. This leads me to believe that the HD4350 card died.
17. Throughout steps 11 to 14, Device Mgr > Monitors only show one "Generic Pnp" monitor which is the computer monitor on the integrated VGA or DVI ports. When the HDMI was working, Device Mgr > Monitors used to show two "Generic Pnp" monitors.
Background info: Laptop worked for many years using 6 ft or 10 ft HDMI cables (which ever happened to be handy) to the HDTV in the living room (same TV that the tower PC uses). This was only very occasional use of maybe a day or two, every 2-3 months or so.
The following started when the Tower PC HDMI stopped working in step-11 above.
a. Tested TV's HDMI port using my laptop via a 10 ft HDMI cable. It worked fine.
b. The next day, I wanted to watch a movie on the TV so tried the laptop and it wouldn't work via the HDMI to the TV.
c. Tried the second 10 ft HDMI cable and it wouldn't work either.
d. Restored the laptop's SSD to a known working backup.
e. Laptop still no display via 10 ft HDMI cable to TV.
f. Last resort tried a 6 ft HDMI cable. Laptop displayed on TV.
g. Tried the 10 ft HDMI cable again. Now it displayed on the TV also. Go figure.
Sorry for the long details. If you waded through the details and your detective work figured out whats happening, please post.
From my perspective now, it seems that things worked with long HDMI cables but gradually deteriorated to where shorter HDMI cables are needed to work. This is true for both the tower PC and the laptop. No clue why.
