HD 4870 problems?
I've been reading about the HD 48xx cards producing blank
screens with Vista and DVI output to some LCD monitors. When you go on some of those forums you get a lot of complainers, so I was wondering if anyone here has an insight to the true scope of this issue. Some said they also have the problem with XP. |

Never had any such problem using DVI on both XP and Vista64. Maybe the DVI cable they are using is the problem. My Samsung 226bw shipped with a single link DVI cable and current video cards need dual link cable. Maybe that is their issue? |

With both the PC and monitor powered on, they disconnect and reconnect the DVI cable, which supposedly activates the monitor display. They may get away with this for a while, but eventually it will be bye-bye monitor and/or video card interface chip. |

HD 4870 problems?
The problem with forums, as you are well aware, is that people only go there
to complain. Check the Newegg buyer reviews, which has both positive and negative reviews, with statistically significant sample sizes. Looking at the numbers, 4870 owners don't appear noticeably less satisfied than GTX260 owners. If the blank screens (a definite dealbreaker) were prevalent, you wouldn't see such high satisfaction ratings. Sapphire 4870X2 2GB http://www.newegg.com/Product/Produc...82E16814102768 108 reviews, 86% of buyers gave the card 4/5 stars or better. HIS 4870 512MB http://www.newegg.com/Product/Produc...82E16814161236 57 reviews, 89% of buyers gave the card 4/5 stars or better. Powercolor 4870 1GB http://www.newegg.com/Product/Produc...82E16814131120 38 reviews, 82% of buyers gave the card 4/5 stars or better. Sapphire 4870 1GB http://www.newegg.com/Product/Produc...82E16814102801 32 reviews, 97% of buyers gave the card 4/5 stars or better. eVGA GTX 260 http://www.newegg.com/Product/Produc...82E16814130398 78 reviews, 97% of buyers gave the card 4/5 stars or better. MSI GTX 260 http://www.newegg.com/Product/Produc...82E16814127361 77 reviews, 91% of buyers gave the card 4/5 stars or better. BFG GTX 260 http://www.newegg.com/Product/Produc...82E16814143157 16 reviews, 81% of buyers gave the card 4/5 stars or better. -- "War is the continuation of politics by other means.

Maybe the DVI cable they are using is the problem. My Samsung 226bw shipped with a single link DVI cable and current video cards need dual link cable. You need a dual-link cable (and a dual-link-capable video card) only if you want to drive a monitor that can proccess a dual-link signal, and you want a resolution beyond what single-link DVI supports (i.e., beyond 1920x1200). So for your 22" monitor with a maximum resolution of 1680x1050, a single-link cable is sufficient (that's why the monitor came with one), and a dual-link cable would not help, because the second link will be inactive at the resolution you are using, and the monitor probably does not even connect to the second link. - anton -- M.

That was with one of those 7950GX2 video cards so borrowed a friends dual link cable and it worked fine. Ended up buying my own dual link cable and that is all I have used since. |
