"title": "5.0 out of 5 stars Honestly the best monitor i've ever owned",
"body": "Either I won the panel lottery or this is just a great monitor. I've bought many cheap and expensive monitors and never had one so perfect out the box. Time will tell though. Went from a 34\" 3440x1440 to this 45\" 3440x1440 very worried about bigger pixels, massive curve and the text on desktop being blurry but had nothing to worry about. You don't even notice the curve when your using it (look at your flat tv up close after using your monitor and you will think your tv is bulging outward, it's wild). Desktop text is obviously off but not as terrible as people made it seem. You can use this as a home office work computer and be fine with few adjustments maybe sharpness increase and clear type. Plenty of settings on this thing. MAKE SURE you use PIXEL CLEAN setting on monitor before you use it as it is recommended. Also take precautions about screen burn in. Gaming obviously is amazing on this thing. Ran a bunch of tests and it was all good. Solid design nothing over the top. Thinner than expected. Lights are cool. Speakers on this are in fact speakers (Didn't test speakers too much). Response time is insane but im not hardcore like that. My computer is mid to todays standards which is why I stuck with this resolution. I still like to run games on max settings, high fps and don't mind the resolution. Not blurry at all in game or desktop (except maybe the text being ever so slightly off). Maybe if you went from a higher resolution to this then maybe I can understand being a little put off. Plenty of other stuff I didn't mention. Read more",

They refused to give me a refund, no return option, no replacement nothing. Instead of helping, they kept sending me to the manufacturer and wasting my time. Bad product, and Amazon didn’t stand behind the customer at all. Read more",

"title": "4.0 out of 5 stars Great monitor , well built . Remote would be nice tho",
"body": "Bought this for Xbox play . Been eyeing this and the Samsung ark 2 55” but for gaming decided to go with the smaller 45”. And when it finally hit a sale price I grabbed it . Monitor showed up in two days . Easy to assemble. Very sturdy materials . Aluminum not plastic . Has two hdmi and one display port for inputs . Not gonna lie maybe two display ports woulda been nice as well as an hdmi out or optical sound out but it is a pc monitor primarily by design . It does have an Audio 1/8th inch jack for headphones so gonna try that with a sound bar . This model has the square base. Most brick and mortar stores around me have the weird pyramid arms so I am glad I got the square base as it takes far less room on my desk . I do wish it came with a remote, having to enable PIP AND PBP via the button on the bottom to me isn’t ideal and I will be using this monitor in split screen for productivity as well but I’m sure I will get used to it . As for gaming . I’m primarily COD and FORZA. COD is amazing on this monitor . It truly helped my game play . And forza is very immersive in cockpit view inside the car . I still need to tweak and explore the monitor settings to optimize but really enjoying it so far and can’t beat the sale price Read more",

"title": "5.0 out of 5 stars For daily use it’s an awesome upgrade!",
"body": "The curve on this monitor is NOT bad at all. It’s been called “severe” among other things, but I use this as a daily monitor for work, streaming, some gaming, etc. so it’s all over the place on use cases. It was a noticeable improvement over a 32” monitor, and the added width makes a big difference (no pun intended). The DPI of 96 isn’t razor-sharp, but I’m not 4 inches from it looking for soft edges or gotcha disappointments. It’s fine so don’t worry about it. The text quality is as good as most others, and frankly isn’t a problem at all. If a pure text-displaying microfont monitor capable of competing with 5K is your requirement then look elsewhere. But if you want a fantastic big OLED with awesome black levels, smooth movements when gaming, and popping colors with zero bleed for mixed use then jump on it. Read more",
