Uncalibrated – Maximum Backlight Level
Lenovo claims 450 nits for the R45w-30, but my sample didn’t quite get there. 415 nits, however, is extremely bright when a monitor is this large, so I have no complaints. The default brightness setting of 75 is only a tick above 200 nits, which is an ideal light level here. The black level of 0.1341 nit is very good relative to other VA screens and delivers a solid contrast ratio of 3,098.2:1.
After Calibration to 200 nits
Calibration makes no difference in contrast, which remains just over 3,000:1, excellent performance. The top four screens are nearly identical to the naked eye and will have a lot more pop and depth than the IPS-based Monoprice, which is a decent monitor in its own right.
ANSI contrast drops a little to 2,770.9:1, but that is a typical result. I noted a slight hotspot in the bottom center of the screen that is affecting this test. Again, there is no cause for complaint.
Test Takeaway: The R45w-30 delivers average contrast for the VA ultra/mega-wide monitor class. It can be set quite bright which will be an advantage for those with sunny offices. Black levels are about as good as it gets for LCD monitors, so the picture is vibrant and saturated with deep shadows and bright highlights.

Neilbob Looks decent enough, and it'd be nice to have for certain things, but I just don't think I'd be able to work with that aspect ratio. Multiple smaller monitors > a monitor that could double up as a surfboard. I'm old fashioned like that.Reply
But I'd be terribly impressed if someone could legitimately tell the difference between 165 and 170 Hz. I might buy 'em a beer or something. -

Same. Something about the separate monitors that mentally works better for me. Another thing with massive wides is if you do any zoom/screen sharing. I have a colleague at work (remote) who when he shares his ultrawide it tries to share the *whole* thing into my 27" making it basically unreadable.Neilbob said:Multiple smaller monitors > a monitor that could double up as a surfboard.

cknobman I've always been curious about ultra wides like these but never quite enough to pull the trigger.Reply
As a developer I always have 2-4 screens going and really value as much screen space as possible.
Just not sure that curve would be good staring at all day. -

"There are many choices in the 21:9 aspect ratio, but by the numbers, they only equal one-and-a-half 16:9 screens."Admin said:The world of extreme gaming monitors grows by one with Lenovo’s Legion R45w-30. It’s a 45-inch DQHD VA curved panel with 5120x2160 pixels, 170 Hz, Adaptive-Sync, HDR400 and wide gamut color. It’s like a window to your favorite games.

FoxTread3 March 23, 2024 - I think it is kind of fun the way many of us humans like big things.. I have my favorite female anatomy measurements ;):cool: I have a Dell 32" LCD monitor and an Alienware 34" OLED monitor. For sharpness and color accuracy, the Alienware wins hands down. When the Dell dies, I'll replace it with another OLED. I use the desktop PC that the Dell is connected to. To do all of the usual online stuff like surfing, reading and writing emails etc. I even watch videos on it. However, for the best video viewing I use my other desktop PC connected to the 34", and that is also my gaming setup. I guess some people really benefit from having a curved monitor, but I find my LG 55" OLED TV fills my needs for a large screen with OLED video quality.Reply -
kira-faye For $800... Just buy a used 42" 4K OLED. You'll never catch me paying that kind of money for an LCD panel.Reply
I got my 42" Sony for $600 by being patient watching local ads. -

a 4K screen isn't ultra wide. Entirely different form factor.kira-faye said:For $800... Just buy a used 42" 4K OLED. You'll never catch me paying that kind of money for an LCD panel.
