Asus, I have to say I’m disappointed after seeing dozens of videos having to explain this fix this simple malfunction that any other equipment company would have been able to prevent.

[DavidBarrowIII]

I have had multiple Asus ProArt monitors go bad after the mains power went out and came back on. No amount of cycling/trouble shooting made them work again. Very said. I really loved the ProArt monitors, but I have had three of them go bad so far.

I was the biggest Asus fan, but will never buy Asus again. Screen is only white, just out of warranty date. My Samsung is 10 years old and still runs like new. No help from Asus.

PG279QM - The HDMI ports don't work properly with any of these tips, or with the included / or with multiple alternate high end, high speed HDMI cables. The HDMI ports on a brand new PG279QM simply don't work properly (9 times out of ten, no signal) - limited to the one, single Display Port for using the product.

Just bought my monitor Pro Display PA248QV last month, everything was fine, but not until today… i didn’t on my monitor for almost 3 days bcs i was away. But today when i want to use my monitor, nothing happen… the monitor just won’t turn on. I tried to use the power cable at my other devices and the device can turn on, but when i try again on my monitor it won’t power on…

This is not helping. I have brand new ROG STRIX XG32AQ, it worked well for a week and now I have to replug the power cable every single time I turn on my computer or I need my screen back from screen saving mode. It is so frustrating. Cheaper monitors weren't doing that in 20 years. And now I'm so frustrated that I'm reading so many bad reviews for that model. Next time I'll probably take another brand. :(

I have a VG278Q the light is turning on, but the monitor is still black any suggestions?

[giphk]

The LED light is on but the screen stays black and the asus logo doesn’t appear

[BladezzWoW]

I have an Asus PG32UQ I bought on July 2021 and was working fine, now when it turns on, only a white led light under the screen comes up but nothing shows on the screen, not even the logo, so I can't use the menu on the screen as is all black (off?), I used a flashlight to see if there was any backlighting at all but nothing, tried different PCs, a laptop, PS4 and PS5, also different HDMI and DP cables and nothing, ac adapter, /power brick is the original that came with the monitor. Is there any way to get it back to work? Monitor was so expensive to have this kind of issues...

[TheBlankJoker]

ROG Strix XG27UG. Power LED is Solid Red for a short period of time before going back to off.

[ForeheadSweat]

My ASUS VG279QL1A turns on, with backlighting, and LED indicator WHITE, but no OSD, no “signal” indicator, nothing on thr screen but black with backlighting. Updated gpu drivers, unplugged-plugged, used different DP cable, plugged into different DP slots. DURING GAMING IT TURNED BLACK AND NOW IT WONT COME BACK. PLEASE TELL ME WHAT I CAN DO ASUS.

Unfortunately, this is useless. My monitor just won't wake up automatically. It says HDMI not detected when turning on the computer. However, I just need to press the menu button, and everything is fine. This is the first time something like this happens to me with a monitor. I just bought a VY249HE, and I regret it.

[LAARRRRRYYY]

I have the Swift Rog PG279QM and I’ve taken good care of it. I was doing homework and all of a sudden my screen went black. I unplugged and replugged in a different outlet and it didn’t help. The power led will not stay on and flashes whenever I plug in the power cord. I’m disappointed because not only did I buy this expensive monitor that won’t work but I also got a buddy to buy one not too long ago. I have no idea why it would’ve stopped working like that.

I have the asus v2g49 144hz monitor and im getting no display when everything is plugged in i tried display and hdmi and they wouldnt work and i thought i needed a new cable and i put the new cable in and it still didnt work so i got a new powercable and it still didnt work and it also turned on randomly today and i was very excited thinking it was fixed but now it wont turn back on. And i forgot to mention before my monitor had this problem when it would go to sleep mode it would flicker the asus logo and then if i wait it out it turns on and when my monitor started working randomly today it was doing the same thing so i waited it out and it started working and now it wont work anymore. I don't know what the issue could be because it isn't a cable issue or anything like that and I think it might be a problem with the inside and this video did not help me at all.

[TSLMachine]

VG278QR, power indicator LED is on white but screen doesn't display anything. I have tried swapping the DP cable, turning it off then unplugging it then holding the power button for about a minute then plugging it back in then turning it back on, the monitor still doesn't display anything. My PC detects the monitor and shifts the whole arrangement whenever I turn it off and/or unplug the monitor.

[josneira]

sorry but all this info is trivial and obvious, do asus monitors have error codes as many pc mobos do?
because mine flashed 3 times the asus logo then went black, yes everythings connected, just started doing this i believe afer a win update, but the light is on the adaptor/psu it comes on under the power switch for the monitor and the hdmi connectors are fine, ..this is the 4th time in succession it has done this, then after a few minutes it turns on nirmally, ,,clearly somethings not right and that's what i'm trying to find out, this help video, doesn't explain anything at all.

[ViktorasFr]

i have Asus MG28U.
And having black screen issue and cant seem to get it to work :/
My PC detects the screen and everything but nothing is showing up, power comes through to the monitor and seems fine but just wont show anything on it, other monitors work fine.
Tried swapping power cable, tried 2 different HDMI cables and DP cables as well, nothing seems to work.

[andrevalencia]

I have Asus Tuf Gaming VG27AQ3A, Its a week old yet I already have a problem of it not turning on. Already did this but still it doesn’t turn on. Already checked the plugs it doesn’t have a problem because my ps5 is turning on yet my monitor isn’t

[stefenhill]

None of these steps work. I've had this monitor for less than 2 years, I won't be buying ASUS ever again if these things just stop working, look at all of these comments...

[madmaduk]

Wouldn't boot to bios, monitor woke but froze with tiny white line in the middle or the screen on a solid black background, tried everything possible. Turned out to be a faulty USB device or port. Not sure which. Just removed all the USB fobs that were plugged in and bingo, It now boots to bios. Now I have to work out if it's a USB port or hardware that's plugged into one. But it's booting and that is the main thing. Hope that helps somebody.
