New user here - joined to post this as I am in need a great deal of urgent help!
I recently bought the shimain Achieva QH2700-IPSMS Edge Eco 27" LED 2560x1440 AH-IPS DVI PC Monitor on the recommendation of this thread.
This one, to be precise:
and am having a devil of a job getting it to work properly.
1. The monitor is giving huge graphics glitches, with the screen flashing irregularly, and with stars appearing all over the screen.
2. It isn't displaying the full resolution either, as can be seen by two black bars either side, even though the card is showing the resolution as being the correct native resolution for the monitor.
I made a YouTube video of the problem here: http://www.youtube.com/watch?v=bvnMBn96qKI
The image below (sorry, crap image) shows the resolution showing correctly as 2560x1440, but the black bars remain and the monitor is not displaying the correct resolution.
If I change the resolution to something else other than 2560, then I get nothing at all (which I think is the correct behaviour for this monitor). Unfortunately, the computer seems to then remember the settings for the monitor and then I cant get anything back off it.
I can sometimes get the screen to be stable - i.e. no flashing or glitches, but the screen still show the black bars either side. Also, when I change the resolution, the monitor clicks as if it is changing resolution, but I just get a blank screen, as if the monitor is just waiting for an input. I can sometimes get the graphics glitches even when no cable is connected to the monitor at all, and it's just running on power with no input.
My Graphics card:
which says it supports the resolution. Driver is up to date. I do not want this for games, just for Photoshop/Lightroom hence the passive cooled GC.
In fact, it's the second graphics card that I have tried with the monitor. I changed the first one I bought (http://www.sapphiretech.com/presentation/product/product_index.aspx?pid=316&lid=1
) at my local PC World as I thought my problems must be down to my graphics card rather than the Shimian monitor.
I also have a second older machine that has a graphics card capable of outputting 2560x1440, but that gives the same problems. Either black bars, either side, or monitor appears to be waiting for input, with occasional glitches/star patterns from both.
I have contacted accessorieswhole, who were helpful communicators before I bought the monitor but haven't heard back from them yet in two days. However, it has been the new year so am not surprised in the least. Don't fancy sending it back - I haven't even received the HMRC import duty bill for this yet. God knows if they will accept that I have sent it back!?!?!
I suspect I might have a faulty monitor, but would welcome your opinions on this...
