Botmonster TechAW3926QW bad picture
If your AW3926QW shows a bad picture out of the box, the fix is almost always in the settings. Update to firmware M2B102, switch to the Creator sRGB preset, pick the right HDR mode and sit level with the center of the screen. The one thing no setting fixes yet is a short edge dimming after bright games.
Key Takeaways
- Most AW3926QW picture complaints go away once the settings are right.
- Creator sRGB mode tames the loud, oversaturated colors of the default preset.
- True Black 500 is the safest everyday HDR mode.
- The green edge tint comes from viewing angle, so sit level with the center.
- Brief edge dimming after bright games is built in and has no off switch yet.
Why does the AW3926QW picture look wrong out of the box?
The first hour with a new Alienware AW3926QW can be frustrating. One buyer on r/ultrawidemasterrace wrote that the screen “SUCKED” on day one. He then worked through the monitor menu, Windows and the NVIDIA driver, and ended up delighted.
Once this thing is properly dialed in, the picture quality and immersion are insane.
Four things make that first impression bad:
- Colors look too strong. The default Standard preset pushes colors too far, so skin looks red.
- Shadows look a little light. Tom’s Hardware measured gamma at 2.14 instead of 2.2, and Custom Color can’t fix it.
- Too many HDR modes. There are seven to pick from, and the wrong one makes games look too dark or too bright.
- Glare and the curve. The glossy screen reflects lamps, and the curved edges shift color at an angle.
Out of the box, the panel measures a grayscale error of just 0.70 dE, well into professional territory.
Flash firmware M2B102 before you change anything else
A firmware update can shift picture presets, so update first and tune second. TFTCentral tested M2B102 and found a change that Dell’s release notes skip. The update fixes the sRGB gamma curve in the Creator sRGB mode. That mode now tracks the sRGB curve from the factory calibration report, where it used to follow a plain 2.2 curve.
Everything else in that mode measured the same, including white point, color clamping and accuracy. The edge dimming after bright games also behaves exactly as before, and TFTCentral has reported it to Alienware.
One owner, u/DOHChead, reported washed-out colors and dropped connections after flashing, so recheck your preset and input settings once the update is done.
The best SDR settings for the AW3926QW
The most accurate SDR choice is Preset Modes, then Creator with the color space set to sRGB, which measures a 1.24 dE color average.
the sRGB mode is an excellent choice for anyone wanting the best SDR accuracy
The sRGB mode locks most controls, however, and blocks white balance changes. If you’d rather keep the Standard preset and its sliders, turn on Windows Auto Color Management instead. It removes the oversaturation, with a 5.5 dE ColorChecker average.
Creator also offers DCI-P3, with gamma presets from 1.8 to 2.6. That option suits wide-gamut photo work and lets you correct the light gamma, which Custom Color cannot do.
A colorimeter won’t buy you much here, since calibrating the panel brings gains too small to see with the naked eye.
Full-screen white reaches about 293 nits at the top brightness setting and 37 nits at the bottom. Most dim rooms never need the maximum.
Which HDR mode should you use on the AW3926QW?
Most “washed out” and “too dark” complaints start in the Smart HDR menu. It lists seven modes, but the minor ones behave much like True Black.
| Mode | Peak brightness | Strength | Weakness |
|---|---|---|---|
| DisplayHDR True Black | About 500 nits | Reasonably accurate in bright and dark scenes | Some dimming in very bright scenes |
| HDR Peak 1300 | About 1,200 nits in dark scenes | Accurate tracking in dark games and films | Panel dimming can halve brightness in bright scenes |
| HDR Peak 1300 Bright | Same peak as Peak 1300 | Holds up bright scenes | Can roughly double brightness in dark scenes, lifting shadows |
| Dolby Vision | Just over 500 nits | Hands HDR10 content to your HDR mode | Content detection is hit or miss |
True Black is the safe daily pick, while Peak 1300 earns its place in dark games and films. Peak 1300 Bright comes closest to the look of LG’s 39GX950B , for anyone who wants punch and accepts gray-looking shadows.
Dolby Vision is on by default, and it makes a useful pairing: leave it on and set Smart HDR to Peak 1300. The desktop then gets the True Black-like Dolby Vision look, which beats Peak 1300 for brightness in desktop apps. Windows switches HDR10 games and video into Peak 1300, with a brief black screen at each switch. Detection misses some content, though: HDR YouTube in Chrome stays in Dolby Vision, and so do some games.
Brightness reaches 1,235 nits on a 2% window, 512 nits at 10% and 282 nits full screen. That’s why small highlights sparkle while big bright scenes look flatter. Dell’s user guide adds that Peak 1300 makes browsers and editors look dimmer than True Black, and suggests turning Windows HDR off for office work.
Green edges and dim corners: what settings fix and what they cannot
Edge color and edge brightness are the loudest complaints from owners. In a uniformity thread on r/ultrawidemasterrace , an owner saw desaturated, green-tinted edges on screentester.io and considered a refund.
The green tint is a viewing angle effect
The green shift appears mainly when you view the panel from above or below. Owner u/awowoosas saw the same tint only when looking from the side. It only shows clearly with your nose a few inches from the panel.
To fix it, raise or lower the stand until your eyes sit level with the screen’s center, and sit square to the curve. Head-on, uniformity measures a 3.71% deviation from center, with no visible change in any test pattern.
Judge the result from your chair. u/DOHChead pointed out that phone photos of a curved screen exaggerate edge problems. The same owner’s photos looked more even with Smart HDR off, but that setting also turns HDR off, and u/saint_marco saw no change. Treat it as a quick test at most.
Edge dimming after bright games
After about 30 seconds of bright-scene gaming, the edges dim slightly. Alt-tab to a white desktop and a faint vignette shows, which fades back to full brightness about 30 seconds later. It shows in SDR and HDR alike, though not during dark scenes.
The likely cause is CPC, or Convex Power Control. It’s an LG Display burn-in guard that dims all four edges of the panel, and this monitor has no toggle for it. Dell’s OLED protection features stay on at all times, so no menu setting reaches the CPC dimming. The fix has to come in firmware.
I don’t think this is a hardware limitation, but a configuration issue.
u/aPHAT88 says it hardly registers in games, and u/h0mn0cu7u5 doesn’t notice it on the SDR desktop. u/saint_marco can see it on a mostly white page.
GPU and VRR settings that finish the job
A perfect OSD setup still looks wrong if the graphics card sends limited range or 8-bit color. In the NVIDIA Control Panel or AMD Software: Adrenalin Edition, set these four options:
- Output color format: RGB
- Output dynamic range: Full
- Color depth: 10 bpc
- G-Sync or FreeSync: on
Every input runs 5120 x 2160 at 165Hz with 10-bit color. HDMI needs DSC compression to get there, while DisplayPort 2.1 UHBR20 can run without it.
Anti-Flicker ships off, and it’s best kept that way. It cuts VRR flicker in menus and loading screens, but it also made small frame rate swings feel less smooth. The 48Hz VRR floor stays the same either way.
Fix a bad picture on the AW3926QW in eight steps
Update to firmware M2B102
Download the updater from Dell’s AW3926QW drivers page , connect a USB-A to USB-B cable from PC to monitor, and run it. Confirm that Display Info in the OSD reports M2B102.
Pick the SDR preset
Set Preset Modes to Creator and choose sRGB for desktop, web and photo work. If you prefer the Standard preset, turn on Windows Auto Color Management instead.
Set SDR brightness for your room
Lower the OSD brightness until a full white page feels comfortable from your seat.
Turn on HDR in Windows and calibrate it
Enable Use HDR in display settings, run the free Windows HDR Calibration app, then set the SDR content brightness slider to match your SDR look.
Choose the HDR mode
Start with DisplayHDR True Black. Switch to HDR Peak 1300 for dark games and films, and try Peak 1300 Bright only if you accept lifted shadows. Leave Dolby Vision on if you want the monitor to switch modes by content.
Set the graphics card output
Choose RGB, full range and 10 bpc, and turn on G-Sync or FreeSync. On DisplayPort 2.1 UHBR20 you can turn DSC off in the OSD.
Leave Anti-Flicker off unless menus flicker
Turn it on only if flicker in loading screens bothers you more than slightly rougher frame rate swings.
Seat yourself and test head-on
Set the stand so your eyes are level with the screen’s center. Open a full-screen white and grey test from your normal seat, and judge the edges from there with your own eyes.
When is it the panel and not the settings?
Settings can’t fix a real defect. After the eight steps, add single-color tests to the head-on check, and judge only what shows at a normal viewing distance.
A few signs point to the panel and justify an exchange:
- Edge tint that stays visible when you look straight on.
- Uneven brightness on the SDR desktop with no bright game running beforehand.
- Physical damage, like the cracked bezel u/aPHAT88 found.
u/DOHChead swapped a unit and called the replacement panel perfect. Dell’s three-year warranty also covers burn-in.
