Hi greyst Are you saying I may have to buy a new monitor then? The wife won't be happy as it's only 2 years old! Sandhound is correct with his itinery and i'm using a 15 pin connection as you show. Here's the pdf manual http://downloadcenter.samsung.com/content/UM/200404/20040428114441171_BN68-00633C-01Eng.pdf Page 49 I think you need to look at please. The pc was 2nd hand and I only bought the tower as I thought it would work ok on my tv. Like I said in the original it works ok on my 27inch lcd Tosiba (27WLT56) using the vga and I can change the settings to a variety of resolutions from 640x480, 800x600 etc. Some look better than others. I'll be disapointed with the tv if I cant get it to work/display correctly. I thought samsungs were one of the 'top of the pops' in the digital world. Any ideas of the best route to go? Thanks Johnny D
