Hey guys, I have an LG w2361vg 1080p monitor and it seems like it will sometimes not have enough power going to it and thus shutting of the screen for a second. It is not actually turning off but I do know that it is the monitor and not the video card because I was changing a seting on the monitor earlier today when it did it and the monitors menu also disappeared which wouldn't happen if it was a video card issue.

Do you think maybe it is overheating a component though overall the monitor feels pretty cool?
or is it simply the amount of power I have going to it that is the problem?
maybe I have fried a component somewhere that is supposed to regulate power in?

BlueMak

I am not sure what the problem is. Can you please rephrase the problem you are experiencing?
Not what you think, but what you are experiencing/seeing.

In general, unless there is zero space around a monitor or a cloth or something on top or behind it, a monitor does not overheat. At least not in normal room temperatures. If the room temperature is over 45C, then perhaps you will have a problem.

he screen goes black for a second without turning off the power indicator and then comes back on. he audio going through the hdmi also goes with it. This monitor is sitting on my desk in a house that is usually cold feeling so no where close to 45C especially since my laptop is running at 30C.
sorry about how I phrased it the first time. I switched the monitor to ts own wall socket and it seems to have helped.

BlueMak

Let us know if it happens again.
If it does, try to connect the monitor with a different connection if possible. (DVI, VGA whatever is available)

it happens a lot not just like once before. I will try VGA though.
edit: well I tried it and it isn't a source I can live with as everything is slightly blurry and seems to have images the trail to the right of the screen. and I set the sharpness of the monitor all the way up to get it to look this good.

BlueMak

What matters to find out what the problem is, is, using the VGA connection, did the problem persist?

I use vga to play console games on my monitor sometimes and have never noticed it happen so I think it is fine while running VGA.
could it be an error is the HDMI encryption?

BlueMak

We need to find out if the problem is with the cables, the monitor, the graphics card...
One way to help is to plug in the graphics card to the computer through the VGA connection. As it is now, we only know that the VGA connection on the monitor works. If you use the computer with VGA connection for a long time and it shows the same problems, then it is clear the problem lies with the graphics card. If there is no problem, then we will need to check the cables. There might be an issue with the HDMI cable connecting the graphics card and the monitor. If a new cable doesn't replicate the problem, great, if it does, then it could be something wrong with the HDMI connection on the monitor or the graphics card.
At that point, and if you have proper cables/consoles, you could try to connect one of the consoles with HDMI and see if the problem repeats itself. IF yes, then the problem lies with the monitor.

So, 1)connect the PC with VGA connection to the monitor. Use the computer for a good length of time. Any errors?

2a)If there are errors with (1), then the problem is with your graphics card.

2b)If there are no errors, get another HDMI cable and try that to connect the PC and the monitor.

3)Let us know how it goes.

mcdragon2

well I can already tell you that it isn't with the HDMI cable as I have changed it out as I had 2 anyways.
and I really can't stand to use the VGA but I will try at some point soon.
and also I just remembered that this monitor is refurbished in the first place so obviously something wrong with the design.

BlueMak

We are getting somewhere. When you can try the VGA connection. It doesn't matter if you can't stand to use it. I am not asking you to use it, we are doing this to find what the problem is, not what you find comfortable.

Quick question, is it an AMD 690G chipset motherboard?

no it is an
Mobile™ Intel® PM965 chipset.
its an HP compaq 8510p business laptop. running an AMD mobility Radeon HD2600 video card

mcdragon2

I sent an email to LG and got a response pretty quickly and they gave me no real guidance this time. I will try once more with a reply to them with the email copied. if that gets me no where I might try a warranty return.
I am currently using the VGA port and so far it is ok in terms of the screen flicker thing.

BlueMak

The best thing to be certain, would be to connect your PC with HDMI to another monitor. It can still be a graphics card problem.

I had this exact problem on an Asus AMD 690G motherboard. When I used DVI sometimes the display went black for a few seconds, then came back again, sometimes it went black and never came back and I had to do a system reset. When I used analog VGA, everything was fine. I know of one more person that has a similar problem, when playing video, the screen goes black then comes back again, and it only happens when he is using one of the digital outputs. When he switches to VGA everything is fine, but the VGA output does not offer a good image quality (shadows, pixel snow etc.).

In all cases the problem was the AMD video card, integrated or not. I was unable to fix it, I tried BIOS updates, different drivers, messed with IRQs, power management stuff... I gave up in the end.

People told me to try different cables (an expensive journey for me, as I now have many worthless and yet expensive "premium" quality cables), different monitors, the ultimate fix was an nVidia card. Sad, but true. And no, this is not "flaming"... it's just my personal experience with some lower end AMD video cards.

On a related note, I had pixel snow on my 30" Dell display with all the AMD cards I tried in the past, same story, bought cables, sleepless nights, installs and reinstalls to no avail... It's really sad because the only choice for me is nVidia now...

Sorry to spill all this on you now, but those were some really dark days for me. Your experience may vary.

yep no problems with the VGA all night. A new card is not possible since this is in a laptop. but I will hopefully be building a desktop around Christmas time. Thanks for the help guys

Judas

if the problem doesn't excist with vga.. and if you use DVI and it doesn't excist... but HDMI it does.

99% of the time it's the HDMI cable OR the hdmi output..

Usually the screen going black.. then taking a second or 2 or maybe in 5 for it to come back on is typically a HDMI HDCP handshake issue..

if the hdcp security receives an incorrect bit of information or doesn't receive anything at all even for a split second... the connection is seveared, the screen will go black and then the monitor and computer or whatever HDMI device your using renegotiates the hdcp connection.... a few words are exchanged and then audio/video is sent again and the screen comes back on.

Now i wouldn't advise getting the totally overpriced monster cable HDMI cables which they want to charge you 150 bucks for a 6 foot cable...

but you don't want to go to cheap either .... 3-10 bucks for a 6 foot hdmi cable generally is a bad idea.

generally i stick with the midrange ones for 15-20 dollars... they are built relatively well, can take abuse to within reason and just work.

And even monster cable has had a few cables that won't or refuse to sustain a solid connection like that too... so it's not uncommon to get a faulty cable sometimes.

My best suggestion.. start with trying a new HDMI cable.

mcdragon2

well I have tried a different cable. is there anyway to check the sockets? or the cables for that matter?

Judas

not really.. those would require much more saphisticated diagnostic tools which generally your not going to pick up from any shop and aren't going to be cheap.

Try and different brand of cable..

if that doesn't work.. i'm betting the hdmi output on the card or the hdmi input on the monitor is faulty....

DVI can also be HDCP compliant. You say you had the problem ONLY with HDMI and NOT with DVI / D-SUB(VGA)?

mcdragon2

I do not have DVI output from my laptop. but it was fine with D-sub aka VGA

Judas

try using a hdmi~>DVI adapter.... see if it's the hdmi on the monitor not agreeing with the laptop

__________________

mcdragon2

ok I will do that eventually. I do not have an adapter as this is my first digital monitor

mcdragon2

from what i'm seeing else where you guys are probably correct and this is an HDCP client handshake problem though idk why it would be doing it with internet browsing and games like warcraft 3 that were made before HDCP.
any ideas on how to fix this?

mcdragon2

just installed 10.10e hotfix so we will see how that effects the errors. it updated from a 5.x to a 7.x driver so might do some good

mcdragon2

watched a movie today and its still horrible though it seems slightly better with games

Judas

indeed there is no reason for the handshakes to occur during web browsing and the internet and such...

only duing playback of blu-ray or HDCP required content..

I think there is likely more involved.. it's not likely HDCP itself.. but the actual digital connection failing to be decoded/understood at either or both ends..

Either the card's output is faulty or the monitors input is faulty if the cables your using have been swapped with no change..

I had picked up some DVI cables awhile ago and i frequently experienced similare issues... the cables were faulty...

Only thing i can suggest is to use the VGA connection or try a completely different cable... brand and length....

actually seems better if I do not have the monitor change the brightness with LG's f-engine which is what I had been doing while watching movies. instead I used catalyst to increase the brightness and it seemed fine for the most part.

Judas

a glitch with lgs software..

i never EVER install the supplied software for any of my monitors and keyboards/mice

they've always given some stupid issues...

its not on my computer it is part of the monitor's functionality. and when I switched cables it was to a different length and brand though to a cheap cable.
is there any tips you have on routing cables because my computer and monitor are right by each other meaning that I have the excess cable coiled up in between
