I just recently bought this LCD from best buy and I have a cut out/cut in (the LCD seems to cycle for a brief moment) when just sitting there. It does it more when it's "warmed up" but it's not overheating (from what i can tell), and it does it more when i put the 1920x1080 res to it. I'm using a x1600 ati card with monster DVI to DVI cable. Also using catalyst drivers and catalyst control center ver. 1.2.2425.37188. it's doing it right now...i'm in "clone mode" with my real lcd as the main, but even if i disable my main and only use the westy then it will do that cut out/cut in thing every now and again. Please advise i don't know what to do. ps the firmware on the tv is 1.19 and should be current.

Hey dude, the behavior is strange.... The native resolution of the monitor is 1920 x 1080 therefore using 1920 x 1080 should work fine. This is not a sign..

How about other sources via DVI? Cable box or DVD player? Even though lower resolutions do not scale well or look good, do lower resolutions work ok (no cut out /cut in)?

Later..

I can watch on component outputs from the DVD player (no dvi out on it) and when i started first with the DVI to hdmi adapter then hdmi to the lcd it did the exact same thing, low res high res..didn't matter, but i can turn the tv off and then back on and it'll chill for a while then "warm up" and do it again. the good news i suppose is that i watched the dvd last night through the dvd player and no glitches at all. even when i watch vongo from the comp it tends to not do it (but it has). All i can think is that the vid card is a generic one ( i bought this from powerpc.com pretty decked out but i had a "budget" card put in. probably gonna try a switch with that befor i think about sending it back...

The X1600 is capable of HD resolutions. You are using Catalyst 6.9? Also, make sure the Video Card is properly identified in Device Manager. It should not say something like "X1600 series", it should list the exact model of the video card. I have seen this be an issue. Rule out a bad driver installation by performing a clean installation? Remove driver via add/remove programs in the control panel, reboot and then reinstall driver.

I noticed you mentioned "warm-up". Do you mean the issue does not occur until after the unit has been on for a few minutes? If so, it sounds like bad hardware.

Remember to verify the basics. Check the cable, also try again cable? Also talk to Westinghouse about it.. Sometimes issue exist that are not known to the public..

Please let us know if you got those problems worked out, as I am looking at the same Westinghouse display.

I got almost exactly the same problem:

Problem:
Display goes black (not blue as in no signal) and returns usually 2 seconds later
this repeats two to three times. Only on Westinghouse monitor not second monitor...
(but I cannot test dvi or hdmi connect to 2nd monitor without very expensive adapter)
1920x1280 native res. HDMI cable feels hot to touch on monitor end and screw for next port vga d-sub feels just as hot. I originally blamed the video card and installed venting in my chassis, but the problem remained even with lower temps reported in chassis. I have recently tried blowing over the vents in the back when it starts a "blackout cycle" and have seen fewer "black outs" repeats.
So I'm contemplating attaching 40MM fans to help vent from the upper slots in rear.
Any better ideas, criticism, or solutions are welcome short of purchasing a new monitor.

Setup:
Westinghouse L2410NM (24" monitor, HDMI, component, composite, vga, and audio)
via DVI-HDMI cable from ATI Radeon X800 Mac Edition (Power Mac G5)
alt display 17" Apple studio Display LCD
via ADC (Apple proprietary connector power+signal)
