- color gamut coverage of 98,3% sRGB; 72,2% Adobe RGB; 76,4% DCI-P3
- and a color gamut volume of 108% sRGB; 74,4% Adobe RGB; 76,5% DCI-P3
Usually, I do not mention this while mostly all monitor speakers are not working well but the built-in speakers of the Acer X34P are probably the best-integrated speakers I saw in a gaming monitor so far. Keep in mind that they will NOT replace a good (or even a cheaper) 2.0 audio system. Its IPS panel ensures great viewing angles for brighter image content, whereas viewing angles in dark image content (dark sci-fi or horror titles like The Evin Within) are not really good. This, however, is something which appears to currently ALL gaming monitors while we are still waiting for local dimming or rather direct led solutions.

Deviations in gaming monitors measurement results
- Gamma settings
- Native sharpness settings
- Max brightness
- Response time (overdrive settings)
- Pixel inversion and many more.
- Some people in different forums have micro stutter issues when using G-Sync. I could not really observe stutter issues and there are also many other users that do not really can observe this stutter problem.
- (15.08.2019) Several people have reported that the monitor (as well as the Alienware AW3418DW) starts to flicker after several weeks when using 120Hz. On 100Hz it is "totally fine".

Tips and Tricks for the Acer X34P
Known Issues on the Acer X34P (Variable/Lottery)
- Scanlines on 100Hz and on 120Hz. On 100Hz they are less visible. Scanlines on 120Hz are even less visible than on the Asus PG348Q and the Acer X34A. (Can vary in each unit)
- G-Sync Scanlines: When enabling G-Sync scanlines become even a bit more visible (and STILL LESS than on the Asus PG348Q or the Acer X34A). In addition, it can cause some dark moving scanlines. These are even less visible than the "usual" scanlines. (Can vary in each unit)
- The right side of the panel can be warmer in the color temperature than the left side. (Can vary in each unit)
- Some retention issues can occur (I could observe them only at the Ufo-Test from Blurbusters) (Can vary in each unit)
- (03.04.2018) Still, many people have Scanline issues on the X34P and people on a German forum reported that Scanlines becomes worse over time. In addition, some people have reported that Scanlines started to occur after several weeks or months for the first time.
- A better overall build quality
- Thinner bezels
- Cheaper (at least in Germany - 100€)
- Less (no) scanline issues
- Fewer homogeneity issues and less IPS Glow (But THIS CAN VARY and I also read that users had more issues on the Alienware so that this simply is a lottery)
- The Acer X34P otherwise offers an 8-Bit + FRC panel so that color banding is probably a little bit less visible on the Acer X34P. But since I did not had both units here at the same time, it is really hard to tell a difference.
Pro & Contra
- Currently (with the Alienware AW3418DW) the best ultrawide gaming monitor (panel)
- Compared to the Alienware it has an 8 Bit + FRC panel whereas the Alienware does not have FRC integrated
- 34" with a 1900R curve for an immersive gaming experience
- G-Sync with a very nice range of 30-120Hz
- Very good image quality out of the box
- Very low input lag
- Black equalizer for fps games
- Useful gamma settings within the OSD
- 6 Axis control integrated into the OSD
- Very good integrated speakers, at least for a monitor (They will not replace a good 2.0 system)
- Acer Predators "Ambient Lighting" (RGBs)
- A bit darker top near the bezels inhomogeneity (not visible in games)
- Homogeneity issues on several units
Some units suffer from a cooler color temperature on the left and a warmer color temperature on the right side as same as my unit. On my tested unit it is pretty good visible - In games and movies, it is mostly NOT visible.
- A tiny bit too much sharpness settings which cant be changed within the OSD
- You need a fairly deep desk so that you still have enough space on your desk and not sitting too close to the panel to avoid IPS glow
- Halfe matte panel coating (a bit less matte compared to the Asus PG348Q or the Acer X34A)
- Retention issues(!)
Update: They can vary in each individual unit so that you should check your unit for retention issues when you got your Alienware
- Unfortunately: ULMB still is not integrated
- A clearly warmer right panel side in color temperature
This (the amount) can vary within each unit
- Scanline "issues"
In my opinion, it is not a BIG deal since they are barely visible
- Still, the IPS glow, especially on the left (but much less compared to older 100Hz IPS Ultrawide panels)
The last Monitor Reviews
Do you have more information or user's feedback on the warmer right side issue ?
I am looking for a working (graphics) and playing monitor, but this issue is a MAJOR downer...
If it's still there, I will look for the older models like Predator X34A or ROG swift PG348Q.
Yes: It is simply a total lottery. No matter if you are buying the Acer or the Alienware. So it is still there. The X34A / PG348Q have both MUCH more IPS glow. Not just a bit, the difference is really huge. My Alienware had only a very small amount of a warmer right panel side (it was pretty much not visible) while others have a better Acer X34P unit. If you can RMA, you maybe should give it a try
Now to my question, in reviews and forums I have seen people criticizing the X34P because they have haven't been able to enable '10-bit' in Windows 10. When you reviewed the monitor, did you enable and test the 10-bit functionality extensively?
I also heard about this issue, that many people cannot set 10-Bit, it is just curious why. When I finished the review, I had just stated 8-Bit (without FRC) and I added the +FRC on the page after I read that the Acer supports FRC. I was pretty sure that the Acer has the same color depth as the Alienware so I just messed up with testing 8 Bits + FRC. But tbh, I do not really see a huge difference while playing at 8 Bit or 8 Bit + FRC while I also read from some other people that there is a massive difference (and here I doubt that they have tested both...)
Love the unit as my first ultrawide and the screen space is a great experience to me. There's no dead pixel or bright pixel but unfortunately I have the same issue as yours which is noticeable Warmer Right screen compare to the right. What's more funny is that the Warmer color on the right screen actually looks OK/Normal if you look at it from a straight line - not viewing from Center (sitting position). Hence, I'm not sure screen is brighter or viewing angle make a play here due to its Curve as my previous Dell U2713HM does not have such state.
Due to this, I just configure the RGB/Gamma/Contrast that is whatever available on the net and adjust from there to my acceptable level. It's not so worse now than on stock settings. The built in Audio surprisingly sound not bad at all which is totally out of my expectation.
The only thing i need to do next is to get a monitor arms. The stands of this monitor looks sexy but it takes almost half of my table away which is too near to my face, around 60cm i think.
Yes, the viewing angle will have a direct impact on the color temperature. Build in Audio on the Acer is much better than Average in monitors, that is true.
The warmer panel side (right or left - lottery) is mostly "only" visible while browsing. So the most people will get used to (: But there are also a lot of people which simply cannot stand this "issue". So always the personal tolerance level
I've been looking at upgrading my monitor for the past few years but hesitate due to quality control issues and panel lottery on some of these high end models. I'm currently using a Samsung S27A950 - 27" TN 1080p 120Hz - which has been an awesome monitor for years but I would really like something with a higher resolution (1080p over 27" is not great :P). I play a bit of everything, mainly FPS and RPGs. PC specs are 4970K@4.5Ghz with an Asus STRIX 1080Ti.
I'm tempted to try an Ultrawide for the first time, but not sure if I'll like the 21:9 ratio or if I'll find it too wide - a lot of people seem to love them though and they do look nice in stores. So I've been looking at the Acer X34P vs Alienware AW3418DW. I'm from Australia and the Alienware is around $600 more -(~AU$1600 - Aus Dell site when on sale) than the Acer(AU$999-$1050). If the Alienware is the better monitor I could wait for a good sale. I'm guessing you'd recommend Acer z34p based on price, but Dell has 3 year warranty and possibly better returns if I had issues. Also, the LG 34GK950F isn't available here in Aus. Are there any better 34" Ultrawides coming out soon? I understand that overclocking to 120Hz isn't guaranteed on these panels as I might get flicker later on (which is a shame as according to TFTCentral the response times were a lot better when above 100Hz) So I'm not sure if I want to drop down to 100Hz from my current 120Hz (probably not too noticeable compared to 120Hz though?). The other option is to go with a normal widescreen like the Acer XB271HU. What would you recommend?
Thanks! And sorry for the long read :P
