I'd suggest you RMA it if you can.

Really? Oh man...I'll check my return policy and see what the max is. Other than the pixel shift thing I am really happy with the monitor.

But I'm also wondering why this happens, I mean I'll still RMA my XB270HU because of 3 dust spots but I think I'll mention that too on my RMA note.

I was able to do that the first time, but the last few times I tried that it screwed up my other monitor that is connected via HDMI and had to reboot. A guy on Reddit mentioned I should try the big power switch on the back to reboot the monitor. I just tried that today and it did not help (XB270 went into power save and my second monitor got all flashy and broken). I wonder if it is a cable or video card/driver issue because when I turn the monitor on the Acer and Energy star logo look fine but when it switches to using the displayport is when it looks messed up.

I have a few question about this monitor ^^

Should game mode be on or not? I have it on right now but to be honest I'm not really sure what it does tongue.gif

I have noticed some "motion blur" (possibley not the right term for it, its most noticeable when scenes are in motion, camera panning etc) for instance if you focus on an object in the background and move around the image gets blurred/stuttery, I have g-sync on so I thought that would correct it and ULMB just seems to make it even worse, could it be a nvidia settings issue?

Would it be possible for someone to perhaps share screenshots/photos of thier options on their monitor and nvidia control panel settings? I really like this monitor and I'm not sure that I'm really getting the best out of it :3

Thanks in advance!

What game mode do you mean?
I think this game mode thing is just to save your profiles etc. so nothing what changes your gaming experience (like decreasing input lag or something)

I don't really know what you mean by "motion blur", I mean there is more motion blur on the XB270HU than on a fast TN monitor like PG278Q (because of IPS). It doesn't really bother me, but actually ULMB should fix your "issue" and not make it worse.
Does it work properly? It doesn't work with G-Sync activated, so you have do deactivate gsync and activate ULMB (which also works only max. 120Hz, so you also have to change from 144Hz to 120Hz)
To make sure, that the NV Control panel is not the issue, you could reset it to standard settings. But I don't think that its the NV control panel, which causes your problem.
By the way, make sure you set the OD setting to "Normal". Not "off" nor "extreme"


For me, the motion blur on the XB270HU is perfectly normal, especially because its a IPS monitor. And with ULMB, the motion blur is greatly reduced, but I prefer G-Sync so I deal with the motion blur and enjoy the tearing-free picture tongue.gif

Hmm perhaps I am being overly critical :3 My previous "monitor" was just an old HDTV and it didnt have any of these issues, I guess going from that to a new monitor, perhaps I expected too much from it tongue.gif I guess I will try and get used to it, who knows perhaps I won't notice it after a while. Thanks for your input smile.gif

Hm that actually sounds weird... This monitor should be a lot better than your old HDTV.
The old HDTV should have more motion blur than the acer.

What settings are you using in the OSD of your monitor?
post #3786 of 4149
You may want to check things with Test UFO or do a direct comparison with it. I agree with Addict that it seems very unlikely an old HDTV would be comparable.

Edit: Whoops, fixed my link.

On G-SYNC mode, keep Overdrive on NORMAL, and refresh rate at 144 Hz. On these settings, the XB270HU has far less motion blur than any TV.

For ULMB, set refresh rate to 120 and enable V-Sync in the game. ULMB only works right if V-Sync keeps the game at a steady 120 FPS.

@StargazerLuka

I have just tested ULMB again @120Hz in CSGO.
It works perfectly fine for me, motion is so sharp and not blurry at all. So it is in the UFO Test, the UFO is without ULMB @960 px/s more or less sharp, but with ULMB its perfectly sharp.

So if you play a lot of competitive games like CSGO, definitely turn on ULMB and you should see a massive improvement. Yes, the picture is much darker but a lot sharper so you can spot enemies much easier. smile.gif
I play CSGO everytime with ULMB now (I actually never used it because I prefer G-Sync. I turned g-sync off for csgo, but never turned on ULMB redface.gif). You can also react much faster to anything because you just see it sharper than before, its absolutely amazing imo tongue.gif



But as I said, even without ULMB the picture is really sharp actually. I think the RoG Swift PG278Q was a bit sharper in motion without ULMB, compared to the XB270HU, but its an insignificant difference.


@boredgunner
What do you mean by activating V-Sync? I played CSGO without any kind of synchronisation and it worked fine (playing csgo with vsync would be awful anyway biggrin.gif). Whats the difference with vsync activated?

V-Sync would be to keep the frame rate and refresh rate synced, for the cleanest picture (no tearing). But you're right, competitive gamers won't do this of course. You'll get less input lag with a much higher frame rate than 120.

hmm could it be because I was overclocking the monitor to 165hz? I haven't tested it at 144hz yet because I thought, you know, more was better tongue.gif Going by the ufotest the image has a slight ghosting trail behind it, is that normal?
