Great Value Good Quality Monitor

I got these from a different site, but they are really good 4k screens. I bought 3 for 4k eyefinity! Although no GPU can run any recent games at that resolution 11536x2160!

That brings me to the X-Res function. I have settled for 5760 x 1080 for my eyefinity now so that is not a native resolution, but X-Res means that whatever resolution you choose to run, it will look as if it's on a native screen. There is no blurry that you get with other monitors on non native resolutions.

All in all a great monitor, just missing 120hz 4k, which I don't think is available yet...

1 Dead Pixel

Top specs for the monitor, excelent value for you money!
3 years warranty
The only downside is that arrived with a dead pixel left center. (3 yr warranty)
shoulda bought the Asus.(maybe no dead pixel on the Asus)

Iiyama G-Master GB2888UHSU-B1 28

I was a bit worried when I chose this monitor, on another website's reviews a damning review was left. The reviewer reported that screen was blurred. This is only true if you run at max resolution over VGA (2048x1080) and you increase DPI to the maximum of 150% or 200% (Windows 7). Drop the resolution or DPI and it is crisp and clear. Over the HDMI and the Display-port you get no blurring at all and is joy to use.

One minor niggle, if you connect an Android media player to the HDMI port and the Android media player is set to the default resolution and frequency, the monitor will blank the screen. So there is no ability to play around with the settings once connected to this monitor. To get round this change the media player screens settings on your standard TV first before connecting to the monitor.

I just replaced an old 19" LCD monitor so I can't really say how it compares to other modern monitors, but all I can say is I am more that happy. Especially since it is pixel defect free.

Great 4K monitor for the budget minded!


Runs great at the top resolution of 3840 x 2160. Everything is so small so if your sight isn't good then you may need to change the DPI settings or look at a different monitor.

I have been swapping and changing monitor every x months, but now firmly believe I have found what I've been looking for and won't be changing until the next big thing in Monitors comes along and that's only if I see it as a benefit.

One thing to note if you buy this model, there is a power switch at the side of the socket you plug the power lead into, this must be switched on before the monitor will turn on with the usual power button at the front. Talking of the power button at the front, it's not easy to press, so I would advise you to leave it switched on if you are able to, not sure if this is a design fault or just mine has an issue.

This monitor is worth every penny.

Would recommend to those who are looking for a 4K monitor on a budget at least.
