Only partially true -- the dynamic range reduce trick helps partially.Notty_PT wrote:There is nothing possible to solve the AlienWare AW2518HF overshoot problems on bright colours.
To reduce most of the bright-colors ghosting issue (use NVIDIA Control Panel, not monitor OSD adjustments) to reduce your pixel brightness range 0 thru 255 (digital colors range) to roughly 0 thru 210 .... or 0 thru 230. Or even better lop both ends of your range via adjustments like 15-230 or thereabouts. It's often done by lowering the contrast slider while raising the brightness slider a bit or even better, reduce both ends of your range (e.g. RGB. Digital brightness adjustment, and not backlight brightness adjustment. That forces the monitor to use only the overdrive-friendly colors, and thus makes it better. Basically, you need to force your graphics card to never digitally transmit the brightest pixel colors over the cable, so that the monitor is using only the overdrive-friendly colors. It wrecks contrast ratio, but it solves ghosting problem 50%-90% on some of my screens.
Instructions for dynamic range reduction for reduced ghosting: Go to NVIDIA Control Panel -> Adjust Desktop color settings -> Use NVIDIA settings -> Slide both "Brightness" and "Contrast" downwards in NVIDIA Control Panel. They both default +50%. Lower both to same settings if you only want to chop the top end of your color range. Contrast should be slightly lower than Brightness if you're chopping both ends of your color range. The final settings would be closer to usually Brightness=+40% and Contrast=+30%. Or try Brightness=+30% and Contrast=+10%.[/b] This brightens your blacks and darkens your whites without touching your backlight, forcing the monitor's overdrive to avoid the most problematic ghosty pixel colors. This range-reduce trick works best in conjunction with moderate overdrive (e.g. BenQ AMA High) or dynamic overdrive (e.g. NVIDIA GSYNC), but can also partially help non-dynamically-overdriven FreeSync monitors too.
Sometimes you only need to narrow the colors range a bit. Other times you need to reduce the range massively. But, it's one extra tool in a toolbox of tweaks of workarounds.
It's a band-aid, yes.
And it's a workaround, yes.
Yes, it worsens contrast ratios (dims your whites without dimming your blacks)
And it requires properly understanding it's digital brightness and not backlight brightness that you need to adjust.
And yes, it is a monitor flaw.
But it dramatically improves ghostng for many colors.
Which makes false the statement, "There is nothing possible".
Also, I should stress that the AW2518HF has no dynamic overdrive. For those sensitive to ghosting, I highly recommend the real-brand GSYNC and run it in true GSYNC mode if you're a ghosting-sensitive person. It helps massively in ghosting quality at fluctuating & lower frame rates.
As a result, AW2518H (no F suffix) has better VRR motion clarity than AW2518HF. While AW2518H 144fps might not always be better than the best 144Hz monitors, the 144fps on it at 240Hz true-dynamic-overdriven NVIDIA's GSYNC looks much better than several 144Hz monitors anyway such as Acer GN246HL and a few other ghosty 144Hz monitors, for example.
So many great honest Amazon reviews about 240Hz from former 144Hz users (4.5 stars too), not everyone is fluctuating-Hz-ghosting sensitive. For exqample, a review from that tearing-intolerant person for example, show for that person prioritizes lack of tearing visibility above all else (even ghosting).
One needs to be armed with the knowledge of what you're picky about, and make sure you buy the monitor that you are most happy about. Whether it's staying 144Hz or making the leap to 240Hz.
