Well, that’s a bit of a subjective topic right there. After all, what’s “better”? Monitors in themselves won’t make games better, and since the underlying, core technology of ultrawide and standard ratio monitors is the same (refresh rates, resolutions, HDR, color depth, etc.), the ultrawide factor in itself won’t boost performance. It will, however, quite meaningfully change the way you literally see your gaming.
Within the context of PC gaming, almost all ultrawide monitors these days are curved. However, you may still find the occasional ultrawide, non-curved, non-gaming focused monitor that may prove surprisingly very good for gaming in solid 60Hz. In general, if you want ultrawide improvements to your games, we’d recommend going with a curved model. The main reason to go ultrawide is to increase your field of view and famous “immersion factor”. A curved panel contributes more to that than a simple and flat ultrawide design.
But what’s an ultrawide anyway? Again, this is all relative. Over the last 15 years monitors have largely standardized (just as did TVs) along the 16:9 ratio, giving rise to resolutions like 1920 x 1080, 2560 x 1440, and 3840 x 2160. Compared to 16:9, ratios such as 21:9 and 32:9 are ultrawide. You see, the height of the screen remains the same, it’s the width that gets stretched. So 2560 x 1440 becomes 3440 x 1440, our beloved 3840 x 2160 4K turns into 5120 x 2160 and so forth. What are the benefits of this, you ask?
