I just bought a new Samsung flat screen monitor, SyncMaster 955df, and it gets fuzzy near the border, especialy the text in my web address bar. I have tried everything to get it to focus. I am not sure whether it is the monitor or the settings. Any suggestions on how to possibly fix this or if anyone else has had similar problems.

Specs for the monitor - .2mm dot pitch and 1600X1200 max resolution
Current settings - 1280X1024 at 75HZ

Short expert note: , and are on the right track — the symptom you describe can be caused by either the display or the incoming signal. Before another trip to the store, run a quick checklist to isolate the cause and to make any exchange/test at the retailer decisive.

  1. Try another computer or laptop on the same monitor. If the fuzz persists, the fault is in the monitor; if it disappears, the problem is in the video card, drivers, or cable.
  2. Swap the VGA cable for a known-good short cable and check pins. Bad cabling often blurs edges.
  3. Reset the monitor OSD to factory defaults and run the monitor’s Auto/Geometry adjustments. Then try a couple of different resolution/refresh combinations (both higher and lower than your current setting) to see if sharpness changes.
  4. Display solid red, green and blue full-screen tests (one color at a time). If colors mis-align at the edges, that’s convergence; if all colors are uniformly soft, that’s focus/optics.
  5. Degauss and remove nearby speakers, magnets or large metal objects; magnetic fields and positioning can distort corners.
  6. Show a full-white screen and a text line placed at the exact problem border — that makes comparison between units quick when testing replacements.
  7. Do not open the cabinet: CRTs contain lethal voltages. Service-only adjustments exist; leave those to a qualified technician.

If the problem survives these checks, document it with photos (and the test patterns above) and request an immediate replacement or a manufacturer warranty repair. At the store, test the replacement with your own laptop or a USB-prepared test image so you don’t have to guess after you get home.

It's the monitor. Edge-focus is notoriously tricky on flat-screen picture tubes. I have not found anything on adjusting the focus for this model. A quick check on the web indicates that you are not alone, though it seems to be more of a sample-defect problem rather than a poor design; a replacement should be OK. As a former monitor repairman, I have no problem recommending Samsung as a brand, in general.

Thanks for your help, I just wanted to make sure I wasn't going crazy since I have already taken back one of these monitors that had blotches in each corner. I guess it will take just one more trip to best buy.

KLEJ,

TallCool is correct. A replacement is required. It's unfortunate you have to do so and even more so that you already have once before... but faults such as that are trickier to find at manufacturers quality inspection stations, and are frequently passed without anyone knowing the wiser. You just happened to luck out and get the 2 out of 500 (just an example) that are expected field failures. Perhaps someone is testing your patience? ;)
