No, an unstable HT overclock does not harm a monitor.
No, an unstable HT overclock does not harm a monitor.
Hey everyone,
I had a stable overclock for a while but had to reset the CMOS because I accidentally turned off USB 2.0 for the UEFI setup. I tried to recreate the settings as accurately as possible, but when I tested it with Final Fantasy 15 I encountered a BSOD with an error like "k_mode_exception." That was somewhat expected, but what surprised me was that one of my monitors started cycling through solid colors. Smoke came out from the top vent and the backlight stopped working for more than a second. I think this was likely due to failing capacitors. I’m pretty sure the BSOD was caused by an overheating HT clock.
The big question is: did the crash harm the monitor or was it already failing? (To give you an idea, the monitor I had was a Vizio VMM26 from 2008 connected via DVI-D and all GPU ports are fine.)
Were you adjusting the monitor's speed settings? Or are you referring to HyperTransport technology? A decade is a reasonable duration for a monitor, but it might have failed prematurely. I don't think any signal leakage or connections from the computer could have damaged it. It's possible the power supply suddenly lost its capacity, leading to an overload on the AC circuit that caused the failure?
Eximo:
Were you adjusting the monitor's speed? Or are you referring to HyperTransport? A decade is a reasonable lifespan for a monitor. It seems it might have failed completely. I don't think any leakage or computer connections could have caused it to break. Could the unexpected drop in power from the PSU have affected the AC line, leading to a surge that damaged it?
Yes, it wasn't overclocking the monitor and HT refers to HyperTransport. There could have been a spike in the +5 volt line across the DVI. The other monitor didn't have these problems but used DisplayPort, which doesn't supply power. I hope my PSU is stronger than that one. Otherwise, my USB devices might get damaged.
An intriguing idea. A sudden removal of some 5V sources might cause a significant rise, particularly if it involved one of the PSUs that draws its 5V from a DC to DC converter. This situation doesn't reflect well on the protection measures in place for the DVI port, though after ten years it might have deteriorated. A good approach would be to inspect where the blown component was connected. It could also be a straightforward fix. My brother once salvaged a batch of dead 19" 4:3 LCDs from discarded work. He managed to repair around eleven by simply replacing the cap or regulator.
