Monitor losing power

I just got a new monitor (Achieva Shimian qh270) and am having an issue with it losing power. My video card is a Sapphire Radeon HD 6870 and I've verified it's connected to the Dual-Link DVI port. After a certain amount of time, it varies each time it seems, the monitor will simply lose power. It doesn't go into sleep mode, it just shuts off entirely. I'm able to fix the issue by unplugging the DC brick for a few minutes and then plugging it back in.

I'm curious if this could be as simple as replacing the power brick or whether this is something wrong internally with the monitor. Just wanted to see if anyone on here had had this happen before or had any suggestions to try before returning and getting a replacement device.

I've tried multiple power outlets, both on the power strip and different wall outlet. I haven't tried a new cord, though there was nothing wrong with it before I salvaged it for use with this monitor. It was originally plugged into my printer with no issues. The computer is still running just fine. Sound, display on other monitor, USB connectivity. I end up going to the secondary display, setting it as primary to regain computer functionality, unplug the power brick, replug it back in a few minutes later and all is good again.

Not connected through a UPS.

The only other thing I notice is that the DC brick gets extremely hot. I wonder if there's something wrong within the DC brick that's causing a power shutoff?

Yea I'm kinda thinking something is wrong in the power path in some way or form. If the DC brick is hotter than your other (identical?) DC brick, then I'd call that the culprit. Or at least a very good place to start. Contact Dell and see about trading. There could be a future recall on it... if there isn't one already.

If it's switching off then it must be power related. If you have to unplug it and then plug it back in for it to work then this pretty much makes it even more likely that it's the PSU. However, as it's under warranty and brand new, I'd get the entire thing exchanged just to rule out anything else.

    • Celebrating Windows XP's 25th anniversary this year

      If I could, I would commemorate it the best way possible: Replacing old machines that are still running Windows XP with something more modern, stable and better.     Noone and nothing should be running Windows XP in 2026.
    • Google's new hand-wave reCAPTCHA can be bypassed with a stock photo

      By Ivan Jenic · Posted

      Google's new hand-wave reCAPTCHA can be bypassed with a stock photo by Ivan Jenic Image: Screenshot Google is testing a new reCAPTCHA method that asks you to wave at your camera to prove you're human. So, besides solving puzzles and reading distorted text, you can now use your computer’s camera to pass the verification test. When the hand gesture verification is triggered, your browser asks for camera access and prompts you to perform a simple gesture, like a wave or an open palm. Google says it records a short video of the movement and uses AI to extract 21 hand-knuckle coordinates to complete the verification process. The video is then immediately deleted, and Google swears it doesn't keep it. The process alone can be uncomfortable for people who wouldn’t want their biometric data, which hand scans technically qualify as, recorded. But it gets even more nuanced, as early testers discovered that the new hand-waving reCAPTCHA can be passed with a simple stock image. A user on X tested the new challenge using a stock image of a hand fed through OBS Virtual Camera, and it passed. I wanted to verify it, so I tried the same thing. It took me a few tries and a few stock images, but in the end, I was also able to pass the test. I simply had to readjust the stock image of a generic person waving inside OBS, and Google’s mechanism registered it as a legitimate hand gesture. Once again, it didn’t even have to be a video or an AI-generated hand animation. Given the simplicity of the process, the entire action can be automated in minutes. All it takes is a simple Python script to render the new reCAPTCHA method obsolete. And it doesn’t even have to be an AI bot, which is usually used for solving puzzles and other verification methods. The new reCAPTCHA method is still in its early phase, and Google will, hopefully, update its AI to at least reject still images. However, this incident, combined with users’ initial skepticism about Google’s practices regarding user data, likely won’t make too many people wave at the camera anytime soon.

      Apparently not. I know it is on Edge for business at the moment, but how long will it be before it become on the home version of Edge?
