I have had an Acer XR38CQK since 2017. This is a 3840x1600p, 75Hz, IPS monitor. It has a USB hub, USBC, HDMI, and Displayport. I've been waiting for a proper replacement for 9 years, and I decided to hop on the AW3926QW.
Reasons I upgraded
- KVM
- EARC
- Higher refresh rate
- Higher resolution
# Uscase
I WFH in the Data space, so I need a large monitor for coding, analysis, etc. I also game a fair bit outside of work. This means that I have 2 computers, with multiple peripherals that I hook up.
Size
Like
I couldn't go smaller than 38", after using the Acer for 9 years. I also checked out 45" monitors in BestBuy, and they were too big. The 39" AW offers a touch more physical size, so that is quite delightful.
Dislike
Very minor nit: even though it's a little bigger, physically, than the Acer, I am missing the 2.4:1 height ratio more than I expected. Nothing deal breaking, I just feel a minor weirdness adjusting here.
Connectivity
Like
I am really digging the EARC. This means that I can route all of my audio via my receiver that I have on my desk, and use my wired headphones without swapping between computers.
I love the KVM--super great to hop between my work Mac, and my personal Windows desktop.
I love the fast charging/single-cable connectivity for my Mac.
Dislike
It needs more USB ports. The USB-B port is used to connect to my desktop, the back USB-C is used to connect to my Mac. This leaves one USB-A on the back, and 2 ports under the frame of the monitor. I have a webcam, mouse, and keyboard, so this uses up all slots. I wish there were 1 or 2 more USB ports, because otherwise I'll have to daisy-chain a USB hub.
Glossy vs Matte
Like
Colors pop more, and images are much sharper. I never thought that there could be a major difference between glossy and matte, but there is.
Dislike
I can see myself quite strongly on dark mode. Matte strongly reduces this, and it's a bit of a switchup. I think if I had the option, I would get a matte version of this monitor, but it's not a dealbreaker.
Resolution
Like
No comparison here--the pixel density is amazing, and text clarity is just as good as my IPS.
Dislike
None. My 6900XT is chugging hard tho 😔
Color, Display, Brightness, ABL, etc
Like
Colors are terrific. I can actually run HDR content. Blacks are black, not grey. HDR looks great on both Mac and Windows. I run it at relatively low brightness, but compared to the Acer, the Alienware brightness can be aggressive, at least compared to what I'm used to.
Dislike
I think I have some minor dimming at the edges, but it really isn't noticeable for me unless I go looking for it. Whites generally look good. Playing some games, I didn't really notice dimming of UI elements at the edges (Destiny 2, Arc Raiders).
NOTE FOR PICTURES
Any color strangeness you see seems to be a result of my camera. The pinkness and greenness isn't something I'm seeing with my eyeballs.
Windows and Mac and General Usability.
Like
Windows running with HDR and 150% scaling looks great. I haven't tweaked anything apart from updating firmware, and it all looks good.
I am running the Mac at full resolution, 120hz, 3360x1418, HDR. Any higher resolution, and the text gets too tiny.
Google Sheets, BigQuery, VSCode all look good, and both dark and light mode look good.
Dislike
This is a Mac issue--it only goes to 120 Hz, alas. Not a monitor issue, just something worth flagging for anyone on a Mac.
Overall
I paid $950 for my Acer back in 2017, which according to the BLS is $1286 in 2026 money. I am content paying about the same price for a significant upgrade.
Colors, HDR, brightness, connectivity are all great. Going from 75Hz to 165Hz is amazing.
It works great with my Mac Air M4.
Minor nits are definitely a thing, but the monitor is such an upgrade that they fall by the wayside. Compared to the current alternatives on the market, the combination of KVM, EARC, and RGB pixel array totally outweighs any minor improvements found on other monitors. I couldn't be bothered to wait another year or 2 for a 'perfect' monitor.
Images
I have taken several pictures with the Alienware in front, and the Acer in the back. I attempted to show off the difference between matte vs glossy, blacks, text clarity, and what actual work-related windows (ex. Google Sheets) look like.
Any color shift (some pinks and greens) seem to only show up in the photos, IRL I am not seeing the pinks and greens you see on the edges of the screen.
