AMH A399U 4K monitor

post #1 of 311
Thread Starter 
I was watching this from Tek Syndicate and it piqued my interest. Anyone manage to purchase one and have any experience with it?


http://www.ebay.ca/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR12.TRC2.A0.H0.Xamh+a399u.TRS0&_nkw=amh+a399u&_sacat=0


I don't find 4K useful on a 30" monitor or less, but with a 40" + $550 ish price point... definitely curious now.

King4x4 would love to hear your feedback on this, is this an IPS panel?
post #4 of 311
Me too me too!
post #5 of 311
I was just looking at this the other day. At first I thought it has to be a TN panel because of the price, yet it says 3000:1 contrast ratio and I dont know of any TN with that high of static contrast. Only really good IPS and average VA panels get that high. Seems odd someone can sell a 40" panel that is seemingly of good quality for this price right now. Let me know how the monitor turns out

This one is a little short on DP ports if memory serves. 1 DP 1 HDMI 2.0 1 HDMI 1.4 and a DVI but I could be wrong.

The flicker observable in Tek Syndicate's video indicates that this monitor uses LED PWM Dimming (Side Effects) which ruins motion clarity. 60hz LCD sample and hold blur negates all sharpness benefits 4k can offer when not looking at static content, and PWM blur further ruins motion clarity.



The slightly more expensive Wasabi Mango UHD420 does not use PWM or is Flicker Free. The name brand 40" TV's (LG & Samsung) also use PWM.

Monitor arrived.

Only gripe is the tempered glass ruins the image a bit.

Post the tests that you want

Only if you're sensitive to PWM. I have the Samsung UN40JU6700 and 7500 and and I have no problem with either one playing a variety of games and watching videos.
