Almost anything outside of the default refreshrates yield a "No Signal".
Is G-Sync enabled? Any particular reason you want to run it at 30FPS?

Edit: Just tested it, no signal. Seems it doesn't unless I'm missing something.

I've been unable to do any different refresh rates too (customs ones that is)

Hey everyone!

I just bought a used XB270HU, it arrived today, and I'm having some issues.
I know it was working fine before being sold to me. It was sent via regular mail on a huge and well protected box showing no big signs of any damage.
The previous owner logged about 1350 hours of use on it, according to the hidden menu.

Right now it's connected with the original DP cable to my laptop (Clevo P650RP6, G-Sync, GTX 1060) with a little adaptor (DP to Mini DP). In Windows it's more or less fine, sometimes it flickers to back and on again...
While playing games things get messy... I get horizontal lines and flickering all over the place, like my graphics card was about to die any second. I can't play any games at all...

Tomorrow I will test it on another system as I suspect it has something to do with the DP to Mini DP adaptor (although I had zero problems with it on my last 144Hz screen, no g-sync)

Here's a video of it - https://youtu.be/nuF8VnvongM

And a photo of the cable setup:



On another note, I read some of the pages here but there's no way I can read 400+ biggrin.gif Can someone point me in the right direction on how to safely calibrate it? I know it deppends a lot on each screen but I'm sure there's a few options that everyone agrees are good, thanks!


*EDIT
-Lowering the refresh rate to 120Hz seems to fix all the horizontal lines and artifacts. I still get the occasional flicker but I think it's down to the ****ty DP to MiniDP adaptor I'm using... I'll try tomorrow with a proper cable.

I've never had anything like that happen with mine, games or otherwise :S. Here's hoping it's just the adapter.

It was indeed! Thank God!!
I tried it on my desktop with a fancy DP cable and all the issues are gone. Perfect display now.


On another note, I though I'd share this little mod I like to do to anything made out of glossy plastic, like the ugly stand's base on the XB270HU:

Disassembly


After some work


All done, perfect brushed aluminum look


And it's the easiest thing to do, just take some regular kitchen scotch brite (don't use sand paper!) and rub it in a straight line for a while until the top shiny layer is removed and you're happy with the finish. Then just clean and polish with regular glass cleaner and it will look very professional.

Good to hear it was only the cable causing the issue. Nice work on modifying the base.

Nice can you post a pic with it back and assembled. Would like to see how it looks, before making a decision on whether to take to mine or not. My KB is a Corsair K70 with that brushed finish, so it may work nicely.

Folks, I have an Acer xb270HU since June last year. Working great until today. Was watching a movie on it and pause it for 30 or so minutes. Since power saving were not really kicking in I switch the power off using the front button. Now monitor don't come back (I am writing this using a second monitor). The power blue light stay on all the time even is not connected to the PC only with power cable on it. Anyone experienced something similar?

Have you tried a different DP cable? If no one can offer up a solution I'd just send it in to Acer.

The product page is gone on the US website for some reason.

No, but the cable seems fine since I am using it on my back up 24" Benq monitor (it seems so ugly after one year with the predator). I downloaded the service manual and it seems the blue light always on is indicative of board defect that should be replaced doh.gif . Acer it is although is going to be a pain. Was brought in US but I live in Brazil sad-smiley-002.gif
