Ok it works fine. No dead pixles... perfect LCD

Out of interest: what did you change to get it working?

I am told the dead pixel thresholds will be revised on the next batch going to OCUK - this pessimism and 'play it safe' attitude isn't doing us any favors!

The reason it wouldnt work on its own was that i cant boot into windows without seeing my boot loader

Once thats selected it works fine but only upon entering windows.

I just cant understand why it wont work on its own before entering windows :/

i have to send off my dell monitors tomorrow and wont be able to use my pc now lol

Phoenixdancer · 28 Nov 2010 at 23:09

Still a No go.

Bah seems im going to have to buy a Tv or something with VGA or DVI to be able to see the bios with :/

Such a shame tbh

Try it on a different PC, to see if the same thing happens. No reason that it shouldn't display the BIOS screen, or other pre-Windows info - the EDID info for the screen has all standard resolutions listed.

I take it you've tried using all the different DVI outputs from the video card?

Phoenixdancer · 29 Nov 2010 at 01:15

yea tryed Both DVI from GPU.

Guna try a DP to DVI adapter

Did you try DVI-D?. DVI single link 60-Hz LCD can display a resolution of 1920 x 1200, while a DVI dual link can display a resolution of 2560 x 1600. Not sure if that will really make a difference but worth a shot maybe?.

I would suggest you testing different cables or converters if you use converters.
I had similar issue with my 20wgx2 and 8800GT. Both me and my brother had same problems with 8800GT from different vendors. Lately when I used converter from my 460 on brothers 8800GT it started displaying bios. It might have something to do with EDID/DDC. Also flashing new bios on motherboard/5970 is worth a try.

Phoenixdancer · 29 Nov 2010 at 11:32

im useing Dual link dvi cables.

flashed a new bios for my mainboard, no help.

will have a look if here any new ones for my 5970

Had a quick look on the net for others having this problem. A few things to try:

reseat the graphics card;
turn on the monitor first and give it a few minutes to warm up;
when you do get into windows, check the sync res is 60Hz or if it is, change it to 59Hz. check that the res is set to the native res for this monitor, which is 2560x1600 I believe;
check all connections,including power cord, between monitor and graphics card are fully pushed in;
check bios for any 'suspicious' settings relating to VGA/monitor which might need changed.

tryed all this mate.

The monitor will only allow a 60hz connection, no way of changeing that.

cant find anything in bios that stops a big monitor

Phoenixdancer: have you tried a different graphics card? It seems like a problem with the bi-directional DDC comms. Its a common card which is in use by many of our customers and no problems reported yet.

Phoenixdancer · 29 Nov 2010 at 13:28

Whats the Bi-Directional DDC comms? :O

I will test a diffrent graphics card soon Im getting my mate to bring his pc over

Would i have to RMA my graphics card to fix that issue?

Duff-Man · 29 Nov 2010 at 13:42

Assuming it does work on your mates PC, try swapping your graphics card over into his machine. That way you will be able to narrow down the problem to either the graphics card or the motherboard. If it's the motherboard, then a BIOS update, CMOS reset, or changing some settings may help. If it's the graphics card (which I doubt) then you will be faced with a different set of issues.

Ezyryder · 29 Nov 2010 at 13:44

It is strange though that his graphics card powers up the U2410 fine though.

Yes, it's a strange problem indeed...

The issue is clearly one of incompatibility with the Hazro screen, than of outright inability to display a POST image. Given this, I think there's only so much that we as a community can help. Once he has gained more info from his friend's PC, it would be nice to see Hazro offering some possible solutions...

Phoenixdancer · 29 Nov 2010 at 13:49

I cant remove my GPU as its watercooled

will plug in his 4870 and set bios to load from PCI-E 2 (bypass the 5970)

if it works then its my 5970 haveing the issue wouldnt it?

Ezyryder · 29 Nov 2010 at 13:55

Indeed - but what kind of issue is a different kettle of fish?!?! I would imagine RMAing the card will be difficult as they will need to try it with that specific monitor. May be its an incompatibility between that specific model of 5970 and the Hazro monitor, if that is the case that is seriously unlucky!

FreeStream · 29 Nov 2010 at 14:30

Interested in the 27" CCFL now, any indications you can give that it will be cheaper than the Apple 27" which I can get for £746.13?

Also, does anyone know if I could plug a PS3 into it using a HDMI -> DVI adapter?

smilertoo · 29 Nov 2010 at 16:37

as a last resort add a second cheapest gpu you can find and use that for bios access.

Or in the meantime (until the problem can be fixed) you could:

1. Keep the Dell and the Hazro both connected and, when you're finished with the bios/boot loader, turn off the Dell;
2. Or if you only need to change the boot order, use something like EasyBCD (means you have to reboot everytime you change boot order and no access to bios but the Dell need not be connected).
