Q: QuestionWould you rather this monitor or the C2 42in?(5 answers)
A: AnswerIt depends. If you need a dedicated monitor for your PC, it has more PC oriented features than the C2. If you’re like me and game more on consoles than PC, a TV is a better choice than a monitor anyway as it has features that lean more towards consoles than PCs. Other factor is Size. 48in is a big monitor to sit up close to. I returned mine because it was too big for my desk to be able to sit comfortably and type or game with a keyboard and mouse while sitting that close. If you wait there are newer 42in OLED PC monitors from other brands that have PC features releasing soon. Again comes down to if you can tolerate size and usage.Answered by JayLov1011

Worth every penny!
Got this monitor a couple weeks ago when it was on sale. $800 is definitely a steal, but for the quality that this brings, it’s well worth the $1500. The vivid colors on the screen, the speakers in the monitor, the speed when gaming, THE ANTI GLARE… chefs kiss! I also use this for work (split my screen 4 ways) and it feels like i have 4 regular monitors within the one—it’s amazing. I will never go back to a smaller monitor again!!

A GAME CHANGER!
I have had this monitor for close to two months & I love it every time I look at it. The deep inky blacks are so distracting. The 4k clarity in all of my games are what rejuvenated a huge part of me that had been missing since I was a kid. I completed this purchase 9/7/22 & I have logged 266 hours on my monitor so far. YES IT WILL TELL YOU! & not a single issue. OLED CARE I play & use with the OLED screen care every day all day. There is a couple of settings to prevent any burn in. The image & pixel cleaning that are part of the OLED screen savers setting. They clean the screen while the screen is off after longer sessions. Maybe anything over 2 hours will give you a cleaning reminder. There is also a setting called Screen Move which will move your screen at the speed of light every minute or so so that not all pixels are just shining the same thing. It is a little noticeable in the day time because sometimes you will notice a bezel is bigger then the other ones. This actually makes me happy knowing that feature is working. No burn ins 266 hours after use. I play a lot of Minecraft which is notorious for burn ins with the HUD at the bottom. THE BAD This monitor is next to perfect. The price is a little high, but I found a 1200 deal which was not too bad. It is almost the price of my computer tho, but the experience is worth it. Im sure I have not gotten all of its value yet. I am sure I will. I purchased the 4 year warranty so I am protected. People need to know... This is not a TV. No dolby vision (not mainstream for games). This is a gaming monitor. This is mainly for the PC gamers but I could see this being great for XBSX/PS5. THE GOOD The whole thing is good. Bright colors, Bright panel, Anti-glare, 4k, OLED, 138 HZ, Clarity, OLED

Two thumbs up!
Considering I purchased the item on sale… I can’t say enough good things about this monitor. Beautiful rich colors, stunning 4K images at 120 frames/sec…. My only criticism is reserved for the 100x100 bracket pattern on such a large monitor. It puts limitations on what wall mount you really should purchase for it. The universal mounting systems (I.e. Sanus) with the long bracket rails may put mild strain on the connections where you plug in HDMI/Display Port cables.
