Difference between Acer H257Hu and G257HU?

Solution
1) LCD and LED are usually the same thing now.
LED is the backlight, and LCD is the filter (with all the RGB pixels) that filters the color to what you see. We used to have CCFL backlights, but now it's LED + LCD.

2) Differences?
I can't find any obvious differences. There must be at least one (besides looks) but I can't find it so far.

Just FYI, but the 2nd one is being labelled as "Ultra Widescreen" which it is not. Normal widescreen is 16:9 ratio, and "ultra" is 21:9 ratio.

I literally found no difference.

(FYI, the panel is IPS which is better than TN, though both are "LCD" panels. IPS tends to have higher response times which can show up as motion blur but it's 4ms response time is unlikely to be obvious. I have a higher response and rarely notice the blur issue. The cheaper TN panels are faster so less prone to blur but have lower quality color and washed out problems on angle.)
