Higher than? Never tried, but I wouldn't do that. That would shorten it's life, & I paid too much to do that.
Prefer to run 1280x1024 at 100Hz. Well with-in the monitors capablity.
Have read several posts that suggest running a monitor at it max shortens its life expectancy.
1280x1024 offers 160Hz refresh.
I use a Radeon DDR 32MB w/ 5BNC cable. Yummy.
The Samsung still sounds interesting. The buyer simply needs to be sure that he's getting what he *thinks* he's getting.
Take the Iiyama Pro 450, for example. Somebody might see an attractive price for the "Iiyama 450" & think they're getting a Pro, but they're not. Iiyama has both a Pro 450 + non Pro. Little word 'Pro' makes big diff. Non-Pro is an entirely diff tube. It's not a Diamondtron, it doesn't have near the specs, doesn't have BNC connectors. It's not even flat. Or somebody might see the 'Iiyama 450' and see that it's "not that flat" (like another guy in a similar thread) and think the Pro 450 is a piece of crap, whe he wasn't even looking at a pro model.
What I'm saying is that we need to know (for sure) wtf we're getting for our (hard-earned) money.
