Hi Everyone!<\/p>\n
I built my first computer about 3 years ago, everything worked great, no issues with anything, then within the past couple months I have been getting artifacts and blanking out on my 30″ primary monitor (I have 2 other 19″, one on each side, running off my second video card).<\/p>\n
Below are some of my computer specs\/hardware:<\/p>\n
-Primary Monitor: Samsung 305t 30″ monitor (used at max res on DVI-D)
\n-2 secondary 19″ monitors (estimate at least 5 years old each)
\n-Graphics cards: HIS H489FP1G Radeon HD 4890 Turbo+ 1GB 256-bit
\nXFX HD-489X-ZSFC Radeon HD 4890 1GB 256-bit
\nThe HIS is typically the one running the 30″
\n-Motherboard: ASUS Rampage Formula
\n-CPU: Intel Core 2 Quad Q9550 Yorkfield (2.83 GHz)
\n-Win 7 64 bit professional
\n-Power Supply: Cooler Master RS-A00-EMBA 1000W
\nObservations:<\/p>\n
I cannot find a pattern to make the problems appear. Many times it is horizontal blue lines across part of the screen (typically the black parts in my background). I have seen different configurations of this, sometimes lots of vertical lines when shutting down (right before it moves to the shutdown “splashscreen”). Sometimes it is other colors, red, green. Other times the picture drops out completely for a second or two then comes back. This sometimes goes away after a short while on its own, and sometimes I restart it and they are gone. This has happened when I turn on my system for the first time after being completely off for the night (I shut my monitors completely off with the switched wall outlet, the power supply typically has power to it). this has also happened after several hours of trouble free use. And it has also not had issues for days or weeks at a time.<\/p>\n
The problem will persist when switching videocards, but only with the big monitor. The two other monitors have never had any problems with display.<\/p>\n
I am not overclocking the cards, they are at default and catalyst shows them running without issue and around 60C<\/p>\n
I have an older laptop that I hook up to the monitor and though it is not running at full 2560×1600 resolution, there are no lines that appear (only limited testing).<\/p>\n
Any suggestions to narrow down the culprit?<\/p>\n
And of course drivers have been uninstalled and then updated.<\/p>\n
Any help would be appreciated! The monitor is under warranty for about a month or so, but I do not want to go through the nightmare that so many others have had to based on their reviews. That being said, if the monitor is at fault, I want to send it back before warranty is up!<\/p>\n
Additional Notes:<\/p>\n
About a month ago I purchased a new DVI-D cable, and it *seemed* to help the problem, but they came back intermittently a week or so after. This is typically not a daily issue, though the past two days have seemed to be worse than previously.<\/p>\n
Additionally, I have posted a several minute video for those who care, I switch video cards after the flashing persists for a while, and then there is a few blue horizontal lines across the screen near the end of the clip. Later, after the camera was off, the screen flashed a few times again (on the second card). This leads me to believe it is not the video cards. What are your thoughts?
\nSide note: I usually have the cables screwed in, and I realize many people do not advise hot-swapping monitor, this problem was happening before doing either of these.<\/p>\n
