Question about backlightbleed?

PugLord · 8 Oct 2015 at 19:50

Simple question........should I see backlight bleed on a monitor when the pc is off and also the monitor is off but plugged in?

Monitor in question is a Benq XL2430T.

So i'm guessing i have a problem with my monitor as i do......only way to stop it is to unplug the power cable from the monitor and wait a few minutes.

PugLord · 8 Oct 2015 at 21:04

This is my monitor with pc off and monitor off.

Its still in warranty but i just need to know if this is normal?

PugLord · 9 Oct 2015 at 08:58

.....have you took the power cord out? pull it out and check.

If i pull the power cable out after a few minutes it goes away but returns as soon as i connect again.

A power led coming through?

Not sure what you mean by this?

Led power button is in bottom right corner which is orange when in standby but off when powered off so shouldn't be any light from the button as it's off.

Benq replied to me saying it could take up to 30mins for the capacitors to discharge but with my monitor it's on all the time after turning off the monitor so will see what they say next.

Fantastic service from Benq - Raised RMA Friday afternoon and replacement arrived today.

Unfortunatley the replacement does the same....grrrrr

Can someone else with a Benq XL2430T please try?

Are you sure that its a different monitor? Did you take note of the old monitor's serial number before sending it back? If its not noticeable when the monitor is on they may not class it as a fault. If it makes no difference in windows or playing games I'm not sure I'd be worried about it either tbh.

Its a different monitor as i had to hand mine back to the courier when they dropped a replacement one off.

When the pc is on i dont have any issues.......its after i power the pc off its like the screen is still backlit. It even does it when the only connection to the monitor is the power cable.

My only worry is that something is on when the monitor is powered off which i never seen before.

Would you be happy if your monitor did this when turned off?

Original monitor

New Monitor

Isn't that just the bezel pressing too firmly on the panel which causes the glow?

Even with the panel switched off?

No, you're right. I wouldn't be happy with it. It actually looks worse than the last one?

My issue is that when the monitor is OFF it shouldn't be doing this full stop!

Just had an update from Benq and they have confirmed that they have managed to reproduce the issue and admit it is very peculiar!

They are currently trying to find a definitive solution so its a case of watch this space.

So anyone with a XL2430T see if its affects you.

PugLord · 28 Oct 2015 at 14:56

Update from Benq:

We received a feedback from our repair center; this issue might not be solved quickly due to spare part discrepancy.
Therefore, it is possible to get your own unit repaired, but the estimated time of repair is around 3 weeks.
In this regard, we can also offer you to swap this unit with a fully working upgraded model XL2730Z for an amount of 50 €
Please kindly let me know what option you would like to take, I will then advise with the repair center.

Now i can see that the XL2730Z is about £175 more than the XL2430T so for 50 € (£36) it doesn't sound like a bad offer to me.

And they offering you a true 8 bit 1440p panel for just 50 pounds more is a hell of a bargain. And it will come with V2 firmware installed.

That's 50€ (Euros) so its about £36.......even more of a bargin.

Falkentyne said:
If you still have the monitor, I'm curious, if you use a monitor test program (Eizo monitor test works great, Aida if you have registered it) and use an all black screen, does it look correct?

Will try tomorrow and let you know.

PugLord · 29 Oct 2015 at 11:59

Just tried the Eizo monitor test and all looks fine on the Black screen test so i'm guessing like you said that the standby voltage is turning something on that shouldn't be on.

Just had email from Benq that they have dispatched the monitor and should be with me tomorrow.

Lets see if they ask for the 50 Euros!!

Just received my XL2730Z and when I turn my PC on i just get a blank screen. :mad:

Before i call them to report a possible fault could it be my graphics card? It a HIS 7950 IceQ Boost Clock 3GB card which should work at 2560 x 1440 resolution.
For info I've got it connected via a DVI cable.

Any suggestions?

PugLord · 30 Oct 2015 at 20:56

Just connected a laptop to it via HDMI and nothing....... All I get is the backlight come on and that's it. The laptop did detect it was a XL2730Z but I couldn't get anything to display.

When you connect a monitor to a laptop, you have to enable the display first.

It can either be the primary or secondary display or you could duplicate it with the laptop display.

Did you try this?

Yes i set it to extend my desktop onto both displays.....then i tried duplicate but nothing.

Falkentyne said:
Also on the desktop, make sure you're using the dual link port on the 7950. They have two dvi ports I think, one single ilnk and one dual link.

My 7950 is a HIS 7950 IceQ Boost Clock 3GB GDDR5 PCI-E which has DVI/HDMI/2xMini DP

His panel is completely dead.
He's not even getting the Benq eye care logo or anything. You get the eye care logo when you first power on the monitor, even if it's not hooked to anything.

OP: You don't get the eye care logo at all, right?

Yep that right no pink eye logo or OSD from the menu buttons.

PugLord · 3 Nov 2015 at 22:21

Replacement coming tomorrow.......Wish me luck!

I must say hats off to BenQ for their customer service.
