Anyone know if a Polaroid TLX-01911C will accept 15khz through vga?

I just bought a Polaroid TLX-01911C from Wal-Mart for about $300 bucks after taxes. Although it's shown as a tv i find it to be more like a computer monitor. It has a max 1440X900 16:10 resolution through it's vga and hdmi port and the picture is just absolutely perfectly clear at 1440X900 just like any good LCD monitor.

My problem though is that I tried using my Scart-RGB to ypbpr converter and plugged it into the component inputs on this new Polaroid and the screen is squashed and fills only the top half of the monitor while the bottom half is black. The entire picture is there but it's squashed to fill up only the top half of the screen?! BTW I only tested this with my Super Nintendo and haven't tried it with my genesis though I don't see what difference that would make... It always worked perfect on my Sony Trinitron through it's component inputs.

So is this what it's suppose to look like if the monitor isn't 15khz compatible? I don't get it since my DVD player looks fine in 480interlaced mode through the same component input? My SVHS looks fine through the Svideo input? So why can't my super nintendo look right using the RGB to ypbpr converter through the component input?

What if I built a scart-RGB to VGA cable would it accept the signal and display properly then? I find it a high possibility that this tv/monitor would accept a 15khz signal through vga as it's advertised as a TV even though I find it to be more like a monitor (the text is way too clear to read even from a distance to consider this a tv lol. much better than any laptop that's for sure and even some lcd monitors I'm sure).

If I do build a scart-rgb to vga cable can I tie the composite sync to both the hsync and vsync on the vga side or can I just use the hsync? I swear I read somewhere on here that u can just use the hsync pin... How expensive is a sync splitter if I have to use one? If it doesn't work will I kill my new tv/monitor?

So any thoughts? God bless

Sounds like you got yourself a fixed resolution display.........OR you need to enable scaling.

Most LCD monitors default to maintain aspect ratio + no scaling. In it's menu, you should be able to change this.

It MUST accept 15khz if it's a "TV", but that doesn't mean it will accept it over VGA. The only way to tell, is to try and it appears you have and if it is displaying an image, it does. You just need to figure out if you can get it to scale.
Given that it's marketed as a TV, look for picture settings "4:3/16:9/Zoom" etc. 16:9 setting forced, should scale everything to fill the screen if it scales and works like most TVs do.

This thing is a fixed reslution display with scaling as it is an LCD though it's listed as a T.V. while it does have hdmi, vga, component, svideo, av inputs so yeah

Yes it does have scaling options but that's not the problem. The screen is only filled up half ways vertically though it shows the entire image in a squashed way. It's messed up. I just think it doesn't like my rgb to ypbpr converter and maybe the timing isn't exactly what it wants or something? It works perfect on my sony trinitron and a panasonic lx70 HDTV so I don't know what the problem is on this one...

This thing is advertised as a T.V. so it of course does 15khz but I haven't tried it over VGA yet. I asked in my first post how I could wire the composite sync in the easiest way though I'm probly gonna have to be on my own on this one and figure it out... It'd be great if it worked out this way as the picture would go through less process and be more direct as opposed to using an rgb to ypbpr converter (though it still looks as good that way aswell. Don't know why some folks say the converter will make it look no better than svideo as I found that to be very untrue)

If it's like the two LCD TVs I own, you may either need to hook the C-Sync to H-Sync or both (1 of mine requires both, the other just H) and then RGB to the respective pins on the VGA connector with capacitors if the picture isn't as bright as you'd like.

If you aren't very good with a soldering iron, I'd suggest buying a VGA cable and splicing wires instead of wiring up a new connector. I did just this for my MAME'd VC arcade cabinet, which needs 2 VGA leads for the dual monitors, so 1 cable got me 2 anyway once I cut it in half.

Just get a multimeter to check continuity on pins/wires to figure out what is what. Not all VGA cables use color matching cables (Red wire won't always = red).
After that, it either works or it doesn't. If you wind up with a rolling picture, try changing how the snyc is fed (Both pin, or either pin). If it just won't sync, you'll have to build a separator, which other posts here cover extensively.

Many thanks for your responses you have been most helpful I will try just the HSYNC first and see what happens and I'll just go from there. God Bless
