Solved Monitor blinks randomly - I don't game

[MLT]

Don't know if it is a monitor issue or video card. Sometimes it seems like I can associate it with what I am doing (when watching video or sometimes I will have Adobe apps or Bejeweled up) but then it happens when there is no apparent stress on the card at all.

Doesn't matter if the monitor has been on for minutes or days, same with PC. Sometimes it's constant (anything from 1 to 5 sec of black with seconds in between) and sometimes it has longer intervals.

Card is Radeon 5750 PCIe
Monitor is LG LED 22" (E2250V)
Connection is HDMI (tried two different cables no change)
Win 7 pro SP1
64bit
i7 2.8ghz
6gb ram

Res is set to 1920x1080 (32b) (which by the way doesn't fill my monitor for some reason, which is annoying as hell)

Anyone have any thoughts? My appreciation in advance. (let me know what other info you need that isn't here or listed in my profile)

Hi.

Hardware check first,

You can connect and check with any other monitor.

Check if graphic card is sitting tight in the pcie slot.


Software\hardware check,

[FONT=&quot]Download and install the new version of [/FONT][FONT=&quot]Driver Sweeper.[/FONT][FONT=&quot]

Download the most recent software\driver for your ati [/FONT][FONT=&quot]AMD Graphics Drivers & Software[/FONT][FONT=&quot].

Uninstall ati software\driver,restart in safe mode,run driver sweeper,choose only AMD-Display and clean,restart in normal mode.


Install the new ati software\driver,restart.

Update[/FONT][FONT=&quot] DirectX.[/FONT][FONT=&quot]


Read carefully the instructions and run [/FONT][FONT=&quot]http://www.sevenforums.com/tutorials/160729-nvidia-amd-video-card-test-occt.html[/FONT][FONT=&quot] post here the results.

Thank you so much for taking the time to respond. I apologize for my late reply, I had forgotten I posted here. I checked with two other monitors now. Card is tight, drivers and software up to date, as is directx. I even replaced the video card and monitor with the Radeon 6770 and an LG 27" LED. Connected to monitor with HDMI and still happened. Connected to a different 27" using displayport and so far it is world's better but it still shutters at times. Doesn't blink and i don't lose picture altogether anymore but every once in a while it shutters if that makes sense.

Installed OCCT 3.1.0 and ran CPU: OCCT and CPU: LINPACK for an hour each and showed no errors. The GPU: MEMTEST is unavailable due to no 'cuddy' or whatever (which, by the writeup you linked to I thought this version wouldn't be subject to..?) but I will run the GPU: OCCT and POWERSUPPLY tests and see what that comes up with.

Any additional insight is appreciated, thank you.

Monitor flickers and can't run 2 screens - OCCT results attached

I was hoping someone could help me understand these OCCT results. (CPU Test runs w/out errors every time, GPU gets errors but I don't know how to read these)

Screen flickers randomly. I don't game, I play full screen bejeweled or zuma's revenge occasionally but the flickering is not limited to those times at all.

















I've had real unstable performance for while now. Started while running Radeon 5750 and a 23" LED via HDMI @ 1080p. I've replaced the card for a 6770, replaced the monitor for a 27" LED, replaced connection for display port and still couldn't get rid of the flicker. It did improve from completely blacking out for a second or two at a time, to just vertical flickers for the most part. Currently I have two 6770 cards, running 1920x1080 @120hz via dp.

Tried to hook up another 27" via HDMI but picture on both (but especially the second) gets really unstable and I lose one or both of them quickly.

Specs should be in profile but just in case:

OS: Windows 7 Pro 64bit
Motherboard: Gigabyte GA-X58A-UD3R
Processor: i7 930 2.8gig (modestly overclocked)
Memory: 6g ram
Graphics: Radeon HD 6770 (x2) pcie
Power: 800w
Temperature: b/w 37-43 C
Outlook: defeated

I've upgraded drivers and replaced everything spare the mother board itself. I would really appreciate any help I can get here.

thanks

Nobody knows how to read the OCCT results? Can nobody help me at all with this?

Despite unecessary and ineffectual hardware upgrades, problems persist....

No reply in 3 days and 300 views? Please help!

Not sure if I am doing something wrong or if people just truly don't have any input but with roughly 300 views and 3 days I haven't gotten anyone to touch my post. Looking around, even the most redundant posts seem to get a few replies, some even equally redundant.

Anything I could do differently to get a reply?

Thanks

The third one won't be needed, it just adds more confusion to your thread,
First of all i will ask you to undo any overclocking.

It says your running 2 gfx card at once for testing purposes can you use one at a time for now.
I will be able to assist for another 30 minutes after that i go bed. Someone else will hopefully take a look and reply

 

[brianzion]

have you installed the latest ccc from AMD? Automatically Detect and Install >>> AMD Driver Autodetect

 

[brianzion]

i am using a xfx HD 6770 card with no issues running 3 monitors using the display port and 2 dvi-d outputs, what outputs are you using?

 

[brianzion]

how many and what monitors are you using? what inputs are supported? if you are using just two monitors one card would be fine to run them as there are so many HD 6770 models listed on amd could you tell me what outputs you have please.

 

[MLT]

Thank you for your replies. The cards are both eyefinity edition (ATI) ? And the monitors are 27" LED one samsung one LG the samsung by display port and the LG by HDMI. No adapters. I installed the newest driver tat was released on Tuesday and it worked fine for a day then came back. I disabled AMD's overdrive and it hasn't flickered yet. (5min so far)

 

[MLT]

oh and the ports are two dvi 1 hdmi and 1 full size dp

 

[brianzion]

check the refresh rate to i found using the same connectors for two monitors dvi- d was the best for me

 

[brianzion]

i think one card would be enough to run two monitors you use two cards for crossfire in gaming etc.the chip in the HD 6770 is more than capable of running two monitors this may seem like a silly question but do you have the card powered up from the psu plug for the graphics ?

 

[MLT]

Yes both cards are plugged to power. After trying three different monitors with three different connections (23" LED via HDMI and DVI, 27" LED via HDMI, and 27" LED via DP & HDMI) and upgrading the card I didn't know what it would take to run the two monitors. Seems stable though. It was that ATI Catalyst default is to enable overdrive, once disabled it was resolved.

Knowing that now, I am sure I could get away with the single card. Without intense gaming do you think I will ever see a noticeable improvement for the extra card or am I better off not subjecting the card(s) to the added heat for no real benefit? Thanks so much for all replies.

 

[brianzion]

no you don't really need two cards if you are not gaming/crossfire etc the HD6770 gpu is very good at controlling the monitors as i think i said mine runs great with 2x dvi and 1x displayport i can watch streaming tv on one monitor surf internet on one other and use other for well anything like file viewing its down to having a good ram bank and psu and cpu really. and looking at your spec you will have no problems

 

[chris1neji]

Good to see you solved your problem.
Overclocking can sometimes cause weird problems. Especially graphics overclocking can sometimes display weird things onto your monitor.

 

[brianzion]

if you want to see whats going on with the card and processor etc download this AMD System Monitor >>> AMD System Monitor

 

[MLT]

Thank you very much, I will definitely check out the monitor you mentioned. I have been looking for something like this. I may pull the second card now actually (as it is starting to blink a little bit again) you don't think there will be any issue with the two on one card when I am using DP and HDMI (no DVI)?

Thanks for checking out my specs too, only thing I'm slightly worried about is psu - specs say 800 but noticed while in there last it is actually 700w

 

[brianzion]

no you should be ok using one card for your monitors with using your desired ports,( i find it best for dvi myself) your psu should be fine to im using a 500w coolermaster Elite and i have no problems
