I recently invested in getting a samsung 245bw 24inch monitor and it was fine for the first few days. After those I started to get little blue stars (size of one pixel) in my games of counterstrike scattered randomly across the screen. These would also appear in the screenshots and would glow like before. I was pretty sure that it wasn't something actually wrong with the game though, because when zooming in on the spot it still remained the same size.

Over the last few days I've experienced blue horizontal lines (1 pixel high) slashing across my screen at random heights of the screen. Do i need to rma my monitor or do i need to replace some of my other hardware? Also when i run the ATITOOL artifact tester my computer always passes...

Thanks for your time.

Short diagnostic summary for the Samsung 245BW reports of intermittent single‑pixel blue specks and thin horizontal blue lines. Those symptoms can come from two places: the video pipeline (GPU, driver, cable, PSU) or the monitor electronics (panel/T-CON/driver board). A short, ordered isolation procedure quickly shows which side is failing and what evidence to gather for warranty or repair.

  1. Capture both a screenshot (PrintScreen -> paste into an image) and a smartphone video/photo of the same event. If the artifact appears inside the screenshot image, the fault is upstream (GPU/driver/capture path). If it only appears in the camera capture and not the screenshot, the monitor hardware is likely at fault.
  2. Swap the video cable and use a different input (DVI/VGA/HDMI) or a known‑good shielded cable; bad or poorly seated digital cabling can create repeating lines.
  3. Attach the monitor to a second PC/laptop and attach the original PC to a different monitor. If the problem follows the monitor, it is the display; if it follows the PC, it is the GPU/system.
  4. Observe the screen during POST/BIOS (before drivers load) and run a solid‑color/internal test pattern if the monitor provides one. Artifacts present before OS/drivers or during the monitor’s internal test point to hardware.
  5. Run longer, real‑world stress (gameplay) and monitoring rather than only a short synthetic artifact test; intermittent faults can evade quick tools. Also log GPU temps and PSU stability while gaming.

If diagnostics show the monitor is at fault, record short video clips (include model/serial, resolution/refresh) and avoid opening the chassis to preserve warranty. If the GPU/system is implicated, proceed with driver rollback/reinstall, temperature/power checks, and testing the GPU in another machine before replacing components. Comments from and point toward both sides of this split; the above steps give an evidence‑based way to decide which to escalate.

RMA is the way. Your LCD screen is going flaky. (OH NO ITS GOT DANDRUFF) Good luck with the warranty-you-musta-done-somfin-wrong-so-it's-not covered-department. Pleae give a repost when you know.

are you sure it's the lcd and not my graphics card? i just wanna be sure.

If the flaky business is going on no matter what program you are running, then it is in your LCD. Call the tech support, and describe it to them, they'll have you do some basic troubleshooting, as they must, and then see what they say.
