Customer Reviews

Great monitor, great company.

I went from a 24 inch VA monitor to this 40 inch IPS. It's a huge jump in both size and picture quality. It looked great as soon as I plugged it in (ie. without any adjustments). I bought it along with the Arc Titan desk mount, which is a very sturdy and highly adjustable mounting arm - especially for the price! The optional USB ports in the base are perfect for wireless mouse and keyboard receivers. I'm very happy with both of these items

I can't end this review without mentioning the support staff at Prism, because they are absolutely the best! I spoke with them on the phone and by email on a number of occasions. They are super helpful and very friendly.


Beautiful monitor. Went from a 32 inch 1440 to this bad boy. Almost exactly the same height as the 32 inch but ultrawide. Bought primarily for gaming and flight sims. So happy with the upgrade. Nice colors and image. Heaps of customization and feels built according to the price tag. Not a single thing to complain about. At first it felt a bit washed out but with some simple tweaking it looks amazing.

My PG400U PRO review

Terrific website, very helpful staff, an amazing 40" monitor that has replaced my 34" monitor and is doing a fantastic job with its huge screen, 144Hz refresh rate and 1ms Latency.
I couldn't be happier with it.
And the delivery was hassle free and the courier driver was very polite and friendly. What's not to like I say.
It's was a very seamless experience topped off by an excellent product and at an unbeatable price point.
Thank you Prism+

Great size, great quality.

This is a game changer for editors as there is so much screen real estate. The colours are great and the connectivity to my 16" Mac with the USB-C cord was seamless. Very customisable and I love the multiple ports on the back as I don't have to keep switching between all 4 sources that I use. Arrived within 4 days of ordering which I was happy with.

Adrian Ng
Great value ultra wide monitor

Did a lot of research before deciding to purchase this monitor. And I've made the right choice. The extra real estate is amazing for doing multiple tasks compared to my old 27 inch. Gaming on it is also a very good experience. Ultra wide provides the immersion like watching an Imax movie. Highly recommend anyone to buy this.
