Question about potential LED Backlight Life (ASUS PG279Q)

Zaite · 7 Jan 2025 at 18:47

I have 3 ASUS ROG PG279Q panels that I purchased in late 2018. So they're roughly 6+ ish years old.

They have done a lot of time, I've used the PC (well, the PC has changed, not so much the monitors :-)

) a huge amount of hours over these 6 and a bit years for work and play. It's hard to say for sure, but I would estimate they have now done about 25k to 30k hours of on-time.

It's really hard to find specs on the LED backlight lifetime, I can't find any mention whatsoever on the ASUS website, the manuals or basically anywhere, other than a few articles that suggest they have a 30k lifetime. I don't know if this is MTBF, it's really just a brief mention if at all. Some other similar panels are saying 50k so it seems a bit vague to me...

These panels are still perfect, if the backlighting dies it would be a real shame because I spent a lot of money on them!

Wondering if anyone has any experience with this. Is it a conservative figure? Has anyone had LED backlighting fail due to old-life on any make/model/etc?

Am I just being paranoid :-)

Thanks!

My 7 year old Samsung ultrawide is just starting to intermittently show signs of backlight failure. I'm getting flickering and yellow staining in the middle of the screen on occasions. Was just starting to annoy me, so replaced with an oled.

Interesting... I guess I'll just keep fingers crossed and hope they last as long as possible. Can't really afford to replace them at the moment but will have to if forced!

It did get 4 years of hammering while I was working from home though.

I got a Gigabyte Aorus FI27Q-X in April 2021.
However it started having some backlight flicker last month and also goes blank for a few seconds every now and then (most annoying while gaming online!)
It's been on pretty much every day probably 5 or 6 hours a day midweek and 14 or so hours a day at weekends. so certainly well short of a 30k hr lifespan, but does gaming at high refresh rate stress the backlight more due to BFI?

Would be good to know the expected lifespan of these but I haven't been able to find much about that either, I know I've had mine on far more than average during the time I've had it... but still a bit annoying that's it happening.

I have triple-monitor setup and this is my main center monitor and needs display port for the 240Hz (other two are 60Hz, so HDMI is fine), however since windows rearranges the desktop when the monitor is switched off for power saving, so don't use power saving and just have a blank screen saver kick in. Considering an OLED next since those the only ones with HDMI 2.1, so can get the good refresh rates without the monitor disappearing when power saving is on!!
