Muss mal hier eben schreiben. Hat nix mit IPS zu tun, aber es muss raus
Mein XL2730Z hat wohl eine gefixte Firmware erhalten. Danke für den Hinweis @ Taunuki.
Habe direkt mal Amazon angeschrieben. Bezüglich dieses Problems:
From original review dated 24/4/15
From a monitor point of view the use of FreeSync creates a problem at the moment on the XL2730Z at the moment. The issue is that the AMA setting does nothing when you connect the screen over DisplayPort to a FreeSync system. This applies whether you are actually using FreeSync or not, you don't even need to have the option ticked in the graphics card settings for the problem to occur. As a result, the setting appears to be in the off state, and changing it to High or Premium in the menu makes no difference to real-World response times or performance. As a result, response times are fairly slow at ~8.5ms G2G and there is a more noticeable blur to the moving image. See the more detailed response time tests in the previous sections for more information, but needless to say this is not the optimum AMA (response time) setting on this screen. For some reason, the combination of FreeSync support and this display disables the AMA function.
This only happens when you are using a FreeSync enabled graphics card, FreeSync capable drivers and the DisplayPort interface. If you switch to DVI or any other interface (which don't support the FreeSync feature) even from the same graphics card/driver then AMA behaves as it should again. If you use DisplayPort but revert to an older non-FreeSync enabled driver package then AMA works as it should. If you use a non-FreeSync supporting AMD card, or a card from NVIDIA/Intel then AMA functions as it should. It's only when all 3 things are combined that the problem seems to occur. Obviously if you eliminate one of them to make AMA work properly, you lose the advantage of FreeSync dynamic refresh rate control. The only exception is if you enable the Blur Reduction mode, where the AMA function then works properly regardless of your system configuration.
Having spoken to BenQ about it the issue is a known bug which apparently currently affects all FreeSync monitors. The AMD FreeSync command disturbs the response time (AMA) function, causing it to switch off. It's something which will require an update from AMD to their driver behaviour, which they are currently working on. It will also require a firmware update for the screen itself to correct the problem. Both are being worked on and we will aim to update this review when it is fixed, hopefully within a couple of weeks. Assuming that fixes the issue the performance when using a FreeSync system should be much better than now, as you can move from AMA Off to the better AMA High setting. At the moment if you use the FreeSync function, or even just have a FreeSync enabled system in place, the response times are slower than they should be by a fair amount, and so you will experience a moderate amount of blur. If you need to, you can always switch to DVI or another interface other than DisplayPort to benefit from the AMA setting (but lose FreeSync).
It is unclear at the moment what would be required to update an existing XL2730Z model, and what would be required in terms of new firmware. We will update this review section when we know more.
Lösung ist folgende:
Update 1/6/15
BenQ have confirmed that the FreeSync/AMA issue has now been fixed. A driver update from AMD is already available and should be downloaded from their website. In addition BenQ will be releasing a firmware update for the monitor itself to fix this issue. Current stocks in distribution are being recalled and updated with retailers so future purchases should already carry this new firmware. This is expected to apply for stock purchased AFTER 1st July, as V002 firmware screens should be shipped by BenQ to distributors in late June.
For those who already have an XL2730Z if you want to, you can return it to BenQ for them to carry out the firmware update for you. This only applies if the user is experiencing issues with the performance of the screen. There is no simple way for the end user to update the firmware themselves and it is not encouraged. Users should contact BenQ support through their relevant country website for more information on how to return their screen for the update.
This only applies in Europe and we do not have any information about how this update will be handled in other countries unfortunately. We would suggest contacting BenQ support for additional help if you need more information, now that a V002 firmware is in circulation. You should be able to identify the firmware version you have by accessing the factory OSD menu (hold menu button while powering the screen on, then press menu). The Firmware version (F/W) should start with V001 or V002 and then a date. You are looking for V002 for the updated firmware.
Ich habe also diesen Text an den netten Mitarbeiter von Amazon geschickt - daraufhin die Frage "Welches Problem haben Sie denn?" - "Scheinbar das, welches im Text beschrieben wurde, oder?!"
Nachdem ich dann nochmal alles auf deutsch piekfein erklärt habe, lautete seine Empfehlung "Grafikkarten Einstellungen überprüfen!"
Ja - genau, überprüft. Jetzt läufts
ARGH!
Naja, jetzt ist es bei der Fachabteilung
