I'm already quite happy about 100 Hz though.

@above: I can recommend Hulustar, they had a 0-2 pixel warranty when I bought, I had no dead pixels though, paid $319 ex shipping/customs.
Test mode unlocks the patch that allows for >400mhz pixel clock limit - which happens to be about 99hz refresh rate. So yes, it is likely that with test mode and driver patching, you can go higher.

Hey everyone.
Just got my X-Star on Monday and I've been playing around with it ever since so figured I'll throw in my experience with it and also ask for some help.

So first thing's first: The stock colors are not as nice as my Yamakasi Catleap but I prefer my 120hz overclock over the right colors. I'll try calibrating it eventually.
It overclocked to 120hz without effort!

Secondly: I am confirming some minor burn-in and screen darkening when overclocking.
I don't remember for how long my window was open but I can clearly see my Chrome's address bar with writing in it as well as some details from the white webpage I was visiting at that time when I have something dark open over that area (visible in black-grey only)
It's slowly going away with the trick that involves just leaving the screen white for some time though at least. Been about an hour of pure white screen and it's almost gone.
The screen darkening can be sort of fixed by turning screen brightest to the max and setting the gamma to 1.5 in CCC. But it is still noticeably darker in the top right corner of the screen and that I can't seem to fix no matter what I try.

Now for my problem: The X-star is my primary screen and I have my Yamakasi as my secondary screen. The problem is that the Yamakasi sometimes flickers and even gets randomly flashing green pixels everywhere. This only applies to the Yamakasi as a secondary screen and not when it is primary. Also it doesn't happen when crossfire is off (dual 6970s). I've tried alternating cables but no matter what combination it still happens once in a while.

I've minimized the issue by preventing my video cards from downclocking too far from their "load" clocks but it still flashes randomly every once in a while. Also I don't like how my idle temps have risen from 40*C to 55*C because of limits I've imposed on the downclocking.
I've even tried switching the two graphics cards to see if it was a port issue or something and it didn't change anything.
The only thing I haven't tried is changing the port order because my X-Star's 120hz option only shows up when it's in the primary port of my video card. If I plug my Yamakasi there I can't overclock my x-star to 120hz

This issue does not happen when I replace my Yamakasi with my old 24" 1080p monitor.
So it seems to be screen specific, but only when Crossfire is on. I've even tried using different crossfire bridges to no avail!
I've even tried 3 different driver versions.

Ugh I'm on the verge of just buying new video cards and going with Nvidia for less driver-related issues.
That or replacing my Yamakasi with another X-star to possibly rule out a "different screen-different timings" related issue.

Anyone have any ideas?


P.S. Also There seems to be a tiny hair under the LCD panel's glass.
There's no way in hell I'm going to be able to get that out is there?
luckily it's in the bottom right corner of my screen where the clock usually is and if I'm doing something fullscreen I wouldn't notice it anyways.

Thanks. I had to do it that way because A) My desk is not wide enough and B) It's in my living room and having them set up horizontally would of made it awkward because It would essentially create a wall between my desk and my living room.
For those interested: Link to the mount on ebay can be found HERE
Also, this is the extent to which the top right corner is darker than the rest.

Nice. Maybe I should have gone with 2 of these and had 4 monitors lol

I think that would feel weird though because you'd have no "central" or primary monitor. Don't you think?

Solution: 6 monitors! biggrin.gif Bottom middle as primary.

I think i'll get two 4K displays before I get six 1440p displays hahaha.

EDIT: ****, after two hours of a white background the burn-in was going away but now after 5 minutes of studying I get this...

I took the picture at an angle so you could see it better.

This burn-in rate is insane!
I think I might contact the seller if this keeps up.
Even after downclocking it's still there.
It's only the top right of the screen that burns in where it's dimmer after overclocking.
