perhaps the pip and hdmi in use is a different number.
i have to specify 1,2,3,4 on my realtec based 494K.

i leave quote email notify off, so there is no point in
quoting me all the time. it just wastes forum space.

I will have to check the setting, but I was not given that option.

FYI- quoting is to specify a response to a direct individual (it has nothing to do with email notification). Without the quotes one is just commenting on the forum.

EDIT: I only have one HDMI port on the back of the 434K. The PIP window only opens in SubWin2 and HDMI is selected as the source.

EDIT#2: I got it working. The power cable for the fire stick was not fully plugged in. I also got the audio to work through the monitor speakers. I changed the audio source in the menu from DP to HDMI. I still cannot figure out how to get it though my PC speakers though.

EDIT#3: I still am receiving the flickering/blinking.

thanks for trying - sorry if i got your hopes up redface.gif
perhaps my observation is unique to my panel or to realtec-494K.
in the meantime, I've been flip/skip free for 3 days now.

your stick audio outs directly to your panel through the hdmi cable, so
unless you can audio in to your pc, there's no reason to expect it to work.

Could indeed be something to do with grounding etc. Usually skipping/blanking is due to power surges or mixed signals and the hardware or firmware give up for a moment (resets). But indeed the PIP needs to be on? Not enough if you have the Roku on feeding image, but not displayed?

no, just that the roku3 is completely connected (data and power) so it's transmitting the screen saver to hdmi-1 but pip itself can be disabled. since i'm using wifi for data and the power is DC, i don't see how there is any possible signal grounding going on through my roku3.

update: while playing SC2 at 1440p fullscreen, I noticed screen skip/flip again. I usually game in windows on my desktop, but SC2 map scrolling requires fullscreen to work best, so... obviously i was not viewing my pip at the same time, but it was still connected as usual.

IMHO this seems to be a poorly engineered logic issue - not something-electro mechanical. my guess is the offending logic is burnt into a chip somewhere, which is why crossover is reluctant to offer a fix as it probably involves dis-assembly beyond an average end user.

there's probably a memory buffer or capacitor they went cheap and underrated that can't handle the required data capacity and frequencies - that's what you get for buying a glorified TV instead of a PC Monitor designed that way from the ground up.

update: was watching roku3 through pip and using my browser - saw a flip/skip. so it seems the problem is not gone - just the intermittent frequency of it's occurrence may have been decreased.

Ah, yes, grounding can be understood in multiple ways. DC has always grounding, that's the black wire or the "minus". Grounding everything to the same level, e.g. using grounded AC wires, means that the appliances have a common ground. It's also a drain if there's a malfunction. Thus completing the circuit with a hdmi cable with another device will change the grounding, even if at times ever so slightly. So you never know.

I still have not been able to capture a video of my screen black outs. Also I just noticed that it looks like after it comes back on the screen doesn't look as bright. I'm contacting green-sum to see what he has to say and to add mine to the list of problem monitors. I'll try and get my cam up and running so I can get a good vid of it doing its blink blackout thing.

a new observation (while my dp+hdmi is active) the skip/flip came back regularly whenever I use my usb2 based webcam (logitech c920) and display the moving image (1080p30FPS) in a window on my 494K. the usb2 webcam is processed by my pc not the panel directly, so this observation only furthers the mystery as to why this panel can't remain in sync due to flaws in it's own display logic handling - to be clear, I never experienced any of this on my 6 year old 1200p60Hz monitor using the same PC/GPU.

One more thing I thought of...

when I first got my 494k, i actually got ZERO display. It only started working when I unplugged the cable from the monitor side and plugged it back in (displayport).

Spypet, maybe in the course of plugging/unplugging things you may have shifted something?

If you unplug your second input can you get the flicker to come back?

Hi all - I need to decide between the Crossover 434k and the Wasabi Mango 42. There seem to be some issues with the Crossover 434k? Is this correct? Should i go with the Wasabi Mango 42? Yes or no? If so, why? Thanks for your help - I need to buy one soon.
