My Honest Sceptre C355B-QUN168 monitor Review

This is a top-to-mid-range gaming monitor. If you’re searching for “the cutting edge,” this isn’t it. This is a 3440 x 1440 ultra wide curve monitor with a refresh rate of 120 Mhz. It’s not as weighty as I expected, so the desk mount is a little too big. Still, the desk mount enables me to rotate and have greater control over the monitor’s position, as well as more open space surrounding it.

One thing to remember is that this monitor offers excellent visual quality right out of the box. No trouble with 4K movies in a 21:9 aspect ratio. I had a 49-inch Samsung Odysey G9″… very amazing, but the refresh rate was insufficient, and my video card (GeForce 3060) just couldn’t give full power owing to the vast real estate. With this one, it’s a piece of cake.

Without a doubt, I prefer Sceptre C355B-QUN168 display over a 49-inch ultrawide monitor.” Yes, the extremely huge one seems to be better for work, but this one appears to be exactly on the cusp between games and productivity.

A word of advice: purchase a decent DisplayPort connection, not a cheap one, and you will be able to fully use the potential of this monitor (better than HDMI).
